What are the specific advantages of TIME-SERT over Helicoil or coil style inserts?
|
|
|
TIME-SERT
®
is a thin wall, solid bushing, self locking insert with positive placement.
TIME-SERT
®
inserts are a thin wall solid bushing insert. This guarantees easy
installation and allows for full load use of tapped hole, ensuring protection against stress and vibration.
TIME-SERT
®
inserts are "timed" internal to external which gives a very thin wall
thickness which means TIME-SERTS can be installed in areas of limited space
and clearance.
TIME-SERT
®
being a solid bushing insert gives it added strength, easily withstands high temperatures without damage or deforming. TIME-SERT
®
inserts have no prongs or tangs to break off or deal with down in the hole, which can be a problem in deep holes.
TIME-SERT
®
inserts are self-locking having an actual locking feature which will prevent them from coming out when a bolt is removed. On installation the bottom few internal threads of the insert are cold rolled to expand into the mating external threads of the base material locking the insert in place.
TIME-SERT
®
inserts have a flange, which will give them a positive placement on installation for “accurate specific depths”. This ensures that the insert does not wind down into the threaded hole.
Thin wall, self locking , solid bushing insert with positive placement.
Customers have asked if they may also use Loctite
®
adhesives for additional strength. Yes you may due to the solid wall design. There is no danger of loctite passing thru the threads of the insert and locking up the bolt as in coil types. Time-Sert inserts are used in Aluminum, cast iron, steels and even some hard plastics.

What kit size should I buy, is the kit the internal
or external size?
|
| |
The tool kits listed are the "Internal size". Metric
Example: If your bolt is M6x1.0 and your stripped thread is M6x1.0 you will
need a
M6x1.0 thread repair kit.
Inch
Example:
If your bolt is 3/8-16 and your stripped thread is 3/8-16 you will need a
3/8-16 thread repair kit.
Check the correct size and pitch for your bolt.

|
4. |
When should stainless steel inserts be used? |
| |
Stainless steel is recommended for the medical or food industry, and water
applications or where there may be exposure to the elements as in disk
brakes.
|
| |
|
|
5. |
Can TIME-SERTS be installed in blind holes? |
| |
Yes
TIME-SERTS can be installed in blind holes.
A basic dimension we give is .250 inches or 6.3mm deeper hole, than the
insert itself.
This is the relief angle length of the tap we have to account for to
get a full thread.
This can vary as small taps will have shorter relief angle length than
larger taps.
Again this is the length from the tip of the tap to the first "full" thread.
The extra depth also gives us enough room for the install driver to
slightly pass thru the bottom of the insert to expand the last few threads,
locking it in place.
Example. The blind hole depth for a 5/16-18x.450 should be a minimum of
.700 inches or 17.8mm deep.
Insert length .450 + relief angle of tap .250 =.700 inches or 17.8mm Hole
Depth.
Another thing to keep in mind when repairing a blind hole application is
that you "do not" want to bottom out the driver tool on installation. There
is a simple method to safeguard against bottoming the tool out, by placing a
visual mark the driver tool. BEFORE installing the insert, place the driver tool into the hole and mark
the tool at the point it can't enter any further. Use a ink marker or even
use a small strip of electrical tape around the driver. This way we know
exactly how deep the hole is and there is no danger of bottoming the tool
out.
|
| |
|
|
6. |
Can TIME-SERTS be removed easily? |
| |
TIME-SERTS can be removed with a spiral point screw
extractor, or drilled out with the drill that came in the repair kit.
Not recommended to use EZ-out or screw extractor on BIG-SERT because of the
locking pin at the bottom of BIG-SERT it will create a cam lock effect. Drill out BIG-SERTS.

Screw Extractors
|
| |
|
|
7. |
Can TIME-SERTS be reinstalled? |
| |
Yes, if the threads in the base material are not
damaged a new TIME-SERT can be
re-inserted into that hole. This is a common
practice on CNC pallet changers. When an insert starts to show wear over
time, the insert can be removed with a screw extractor then replaced with a
new one.
|
| |
|
|
8. |
What types of plating are used on TIME-SERT inserts? |
| |
The standard TIME-SERT carbon steel inserts " Black in
color" are plated with
Zinc Phosphate. Sparkplug washer seat
inserts are plated with a copper flash good for heat and anti-seize
properties. Sparkplug taper seat are silver plated.
|
| |
|
|
9. |
What are the torque and pull out specifications for
the TIME-SERT? |
| |
TIME-SERT makes no claims on torque specs or pullout, nor do we provide
them. The reason being there are many factors that can determine the end
result of the insert thread strength. One being the installation process.
1) Was the insert actually installed correctly using Time-Sert tools and
square to the hole? This would have a huge effect on the outcome of the
torque specification. Along with what type of material being inserted,
plastics will not have the same torque values as aluminum's, steels, or cast
irons. Another thing to keep in mind is the length of the insert. Inserts
must match the length of the bolt threading into the hole. Too short of an
insert length could result in thread failure.
TIME-SERT will state that if the thread repair is done correctly and with
the proper length of insert used for the application e.g. the insert is the
same length of the original thread engagement, the result should be a hole
that should match the original torque specification of the hole.
Customers have found in their own testing data that TIME-SERTS have
exceeded their expectations. Many of our larger customers will test TIME-SERTS
before placing them in critical applications and find excellent results.

Can Spark plug repair be done without removing the
head from the motor? |
| |
Yes Spark plug repair can be done without removing the
head by placing a heavy grease on the step tap flutes to catch the chips.
TIP: mechanics have mentioned that using a shop vacuum with a plastic tube
taped to the nozzle end works well for removing any stray chips left over.
|
| |
|
|
11. |
Are special lengths of inserts available? |
| |
Yes we have many special lengths of inserts available
not listed in our catalog. Please inquire with our order department to see
if we have the length you are looking for.
|
| |
|
|
12. |
Can Custom lengths of inserts be ordered? |
| |
Yes custom lengths can be ordered but a minimum of a
1000 insert quantity will be required. The estimated time of delivery is 4-6
weeks.
|
| |
|
|
13. |
What is the correct insert for my SPARKPLUG
application? |
| |
What type of spark plug do you have? Washer seat or
Taper seat. Washer seat sparkplug's will
have a washer to seal the spark plug against the head. Taper seat spark
plugs will have a taper to seal against the head.
Measure from either the spark plug
(Washer) or (taper) to the last thread.
(Not to the end of the electrode). This will give you the correct length on
insert.
TIME-SERT inserts cannot be shortened for length. Please refer to our catalog or web site for length of inserts.
The diameter of the spark plug will be the size. The threads or pitch will
be a standard for the diameter.
Example: If the diameter is M14 the standard
pitch will be 1.25 or M14x1.25.

Can I repair a stripped helicoil with a TIME-SERT
insert? |
| |
No, you cannot repair a helicoil with a TIME-SERT.
The over-sized line in inserts available is called BIG-SERT.
Please refer to catalog or web page for sizes available.

|
|
16. |
Is my hole too large for a TIME-SERT? |
| |
Normally if the hole is just stripped out and has never
been repaired TIME-SERT will repair that hole. You can also check the drill
size from the online TIME-SERT catalog or go to engineering data page, the
drill size should be slightly larger than the stripped out hole.

| |
|
|
17. |
Can TIME-SERT inserts be shortened for length? |
| |
No! you cannot cut off the bottom or top of the inserts
for these reasons. The top has a flange which give the insert a place to sit
for positive placement. The bottom of the insert is the locking portion.
Read more about shorter hole depth options here.
|
| |
|
|
18. |
Do TIME-SERT inserts use special taps? |
| |
Yes, TIME-SERT inserts use S.T.I taps which are
considered special.
S.T.I stands for "Screw Thread Insert" an example would be a TIME-SERT
M8x1.25 repair kit would require a M8x1.25 S.T.I tap, this is "larger" than
a standard M8x1.25.
S.T.I Basic P.D. = Nominal Thread O.D (Basic Major DIA.) - Basic P.D. +
Basic Major DIA.
Example for a "1/2-20" S.T.I tap:
S.T.I "1/2-20" O.D =.500 DIA. - P.D .4675 + O.D .500 = .5325 S.T.I Basic P.D
Taps are generally class 3 (4H limit)
Our taps are made from M2 high speed tool steel.

Why does the NorthStar2000 & NorthStar BIG-SERT have 2
line on the tooling? |
| |
The Original NorthStar 4.0/4.6 TIME-SERT kit p/n
660J-42385-500 only has one line on the tooling because it is specifically made
for the early Cadillac NorthStar 4.0/4.6 engine block only had one depth of
head bolt. This engine block was developed first.
In the year 2000 the North Star block had a change
where the lower bank head bolts were dropped to a deeper depth.
Kit
p/n 660J-42385-2000
The NorthStar BIG-SERT kit will repair the 4.0/4.6
along with the NorthStar 2000 block which have a deeper depth on the lower
bank of the block. Since the
BIG-SERT repair came several years later we
decided to consolidate the two. The
BIG-SERT kit
p/n 660J-42385-500BS is for
blocks that have already been repaired!
This is a second oversized repair.
Question: What if i have a NorthStar
660J-42385-500
kit and want to fix a NorthStar 2000?
Is it possible to do a 2000 repair with my
660J-42385-500 kit ?
Answer:
Yes, this can be done by remarking the tools for
the deeper depth on the lower bank of the 2000.
Core Drill:
The Core Drill has a positive stop collar,
remove the silicone in the set screw and back up the collar starting from
the larger cutting diameter (not the tip of drill) back toward the square,
this should measure 3.100 inches.
Tap:
Mark a line from the cutting edge of tap back toward
the square 4.550 inches.
Driver:
Mark a line from the front of driver back toward
the square 3.550 inches.
Picture of new marking of tools:
660J-42385-500
to
660J-42385-2000
Note: Additional bolt length would be required for deep holes on the lower
bank of the 2000 blocks. Attachment bolts
p/n 662J-42385-604
quantity 2 would be required to attach the fixture plate to the engine
block. The correct kit for the NorthStar 2000 is our
p/n 660J-42385-2000.

Inserts only screw onto the insert
driver 1 or 2 threads? |
| |
What is happening is the plating is slightly heaver on
some inserts that is why it will feel tighter when screwing inserts on
driver tool by hand. This is common on all inserts, if some of your inserts
only screw on a few threads of the driver tool don't worry the driver tool
will screw thru the insert fine when installing. Of course always use oil on
driver tool when installing inserts, this can be a 30wt motor oil.

21. |
Will Honda Drain plug repair work in “Tin Pans” with
oversized drain plugs? |
| |
No! Because the oversized drain plug has oversized the
hole in the drain pan making it larger, so the insert will not hold
properly. The
6601485 kit will work by reducing the hole from M14x1.5 to
M12x1.5 there is no drilling because the tin pans are to thin and the thread
would break out entirely. So no oversized drain plugs in tin pan repair.
Aluminum pan repair:
If the drain pan is aluminum use kit
6601415C,
it does not matter if there are oversized drain plugs used because we are
drilling out the hole to bring it back to its original size. Aluminum pans
have enough material to drill out and insert back to the standard M14x1.5.

22. |
The hole being repaired is shorter, than the length
of your shortest insert? |
| |
One possible solution.
The hole being repaired has a
depth shorter than the length of our shortest insert. There are a few cases
where we do not have a short enough insert for a particular application. For
example: trying to repair a hole 5/16-18 our shortest length insert is .450
inches and the hole depth is .350 inches deep. You can install a TIME-SERT
without using a counterbore. Leaving the shoulder sticking up to remove
later on by milling or filing.
One possible suggestion on this type of installation.
1) Drill hole (2) Tap hole (3) let insert set up with
loctite (4) install insert (5) file insert flush.
Drill the hole out, "DO NOT" use counterbore tool, tap
the hole.
On installation:
Screw the insert in the hole with loctite to the desired
location. Let the insert set up with the loctite before running the insert
driver tool through the insert. The loctite will prevent the insert from
going to deep into the prepared hole.
Use the driver tool to expand the last few threads of the inserts.
The insert will now be protruding or sticking up higher
in the hole, you will have to "file down" or mill the top of the insert to
get the insert flush with the surface. It's recommended to run the insert
driver back through the insert to clean any burs at the top of the insert.
The repair is complete.

How to remove head alignment Dowel. |
| |
With
out the
proper tool
removing
head alignment dowels can be tricky.
The tool in the link above can be purchased from Midwest Shop Supplies.
(763)-309-1014
p/n 662PT6575
Possible work around:
Place a suitable bolt that will fit closely into Dowel so that it will not
crush.
Use a pair of vise grips to hold on the "outside" of the dowel. Slowly work
the dowel back and forth as you use slight pressure under the vise grip with
a screw driver to give up lift.
Use care not to scratch the top of block in the process.
Sometimes head alignment dowels will come out easy and sometimes hard
depending on tolerances of the block, how much the dowel gets crushed in the
process, or rust,
etc.

Can Loctite be used on the external thread of insert.
|
| |
Yes,
loctite may be used on the external threads of the insert, due to the solid
wall design there is no danger of it leaking thru to the internal threads.
Application Spark plug taper seat:
Our loctite p/n 6626020 is
required on taper seat spark plug inserts. Only the taper seat
style spark plug inserts require loctite not washer seat. We are
sealing on the built in taper of the insert so we have a perfect seal from
the spark plug to the insert but we need to insure that the external threads
of the insert are sealed by the loctite to keep any gases from passing by
the external threads of insert as a precaution.
Application Head Bolt:
We recommend our loctite
p/n 6626020 on the external threads of the insert
in head bolt applications and commonly include
p/n 6626020 in many head
bolt kit applications.
Loctite
p/n 6626020 = Loctite p/n 266:
loctite 266 is recommended because of it's higher temperature. Normal red
loctite e.g. part numbers 277 or 271, burn away at 200 degrees which is the
normal operating temperature of most engines.
Loctite our
p/n 6626020 has been tested to 500 degrees without any problems and
will give added strength as it will not burn away when engine temperatures
above 200 degrees are reached.

Head bolt repair tip: Should just the 1 or 2 bad hole
be repaired? |
| |
TIME-SERT would recommend repairing at the very least, all the holes on the
side of the block where the threads have failed. (If repairing a V engine)
If repairing a straight or in line engine block TIME-SERT would recommend
repairing all holes.
The reason for this is simply the weakest link effect. If you only repair
the bad hole or holes and leave the others there is a very good chance the
other non-repaired holes may fail.
Especially with aluminum blocks these days and over heating you can
experience an anneal effect where the material becomes brittle. The only way
to make sure is to remove all the old threads by replacing with steel
inserts.
TIP: Clear packing tape
One last tip we like to mention is using clear packing tape normally used to
close cardboard boxes. If you tape across all the holes on top of the
cylinder block this will help keep all chips from entering the water jacket
and piston holes. This way when the repair is finished you can easily remove
the tape from the top of the block and be assured that no chips have
entered. The clear packing tape is very thin and won't be a problem pushing
thru the alignment bolts included in the head bolt repair kits when starting
the repair.

The video example shows the speed in which TIME-SERT inserts can be
installed in a blind hole applications using a pneumatic push pull tapper.
To our knowledge there is no insert on the market that can be installed
faster in a hand volume application where a specific depth is required. The
insert in the video is a M10x1.5x14mm.
If multiple inserts need to be installed this can also be done using a CNC

Ford spark plug
kit p/n 6605553 Tap will not start in hole after reamer? |
| |
The tap should
cut easily
The problem is you may not have
"REAMED" the hole fully. The reamer has a black stop collar and this collar
must touch the head to ream the 45
degree
counterbore which is pictured in step D.
The problem that can happen is the reamer did not ream all the way thru the
hole so it leaves a step in the hole that will STOP the tap because the 45
degree counterbore was not fully done. This can happen because of 2 possible
things. The reamer is hitting a VALVE or the top of the PISTON which is
stopping it from entering all the way.
Please check again that the valves are closed and the piston is all the way
down, then your tap should easily tap all the way thru.
Follow the 2 man step on getting the valves
closed and piston all the way down on the instructions.
Turn the engine over clockwise from the front use an 18mm socket.
Put your thumb in the hole like your giving someone the "thumbs down" the
top of your knuckle should almost block the hole and you should feel
compression as you come up on the compression stroke.
When you get to top dead center you won't feel anymore pressure use a wire
hanger put down the hole.
As someone slowly turns the engine again clockwise as it is going down on
the power stroke the second it tries to come back up STOP. The valves will
be closed and the piston all the way down.
