WARNING SUMMARY

WARNING SUMMARY

This is a summary of critical WARNINGs in this bulletin. They are repeated here to let you know how important
they are. Study these WARNINGs carefully; they can save your life and the lives of personnel you work with.

WARNING

Always wear eye protection when using a hammer. Eye injury may result if
metal chips contact eyes.

WARNING

Improper number of track shoes may prevent track from being adjusted
correctly, creating a safety hazard. Personnel may be killed and equipment
damaged. For carriers with new track, ensure there are 63 track shoes on
the left side of carrier and 64 track shoes on the right side of carrier for the
M113A2 FOV, M113A3 FOV and OSV. For the M548A1/A3, 66 track shoes
are required for both sides.

WARNING

Do not use a crowbar on the track shoe pins to get leverage. Any scratches
may cause the pin to break and cause the track assembly to fall off the
vehicle while operating. This may kill soldiers and damage equipment. Use
crowbar as shown in the following steps to get leverage to install the end
connectors.

TB 9-2350-369-20-1

WARNING

Not getting the bolt tight enough may result in death to personnel and
damage to equipment if the end connectors fall off during movement of the
vehicle.

For first aid information, see FM 4-25.11.

(2) Install two rings (12474843), sprockets (12474840), and 20 self-locking bolts (MS35764-1445) on
sprocket wheel. TORQUE BOLTS TO 110-115 lb-ft. (149-156 N m). Use torque wrench.
(3) Place sprocket wheel assembly on final drive. Secure with 10 self-locking bolts
(MS35764-1545). Have helper assist. TORQUE BOLTS TO 170-190 lb-ft (231-258 N m). Use
torque wrench.

e. Install T150F Track Assembly on vehicle (Figure 4 through Figure 8).

WARNING

Improper number of track shoes may prevent track from being adjusted
correctly, creating a safety hazard. Personnel may be killed and equipment
damaged. For carriers with new track, ensure there are 63 track shoes on
the left side of carrier and 64 track shoes on the right side of carrier for the
M113A2 FOV, M113A3 FOV and OSV. For the M548A1/A3, 66 track shoes
are required for both sides.
CAUTION
Be sure track shoe orientation matches that of the adjacent shoe. Center
guides can not be next to each other.

NOTE
Track assembly can be installed from front to back or back to front. Going
from the back to front can be easier with the sprocket wheel assembly to
help push the track assembly over the top of the road wheels. Joining the
track together will be between the sprocket wheel assembly and first road
wheel or idler wheels and last road wheel.

If connecting the track at rear of vehicle (M113A2 FOV and M113A3 FOV
only), have ramp closed and secured (see your -10) to allow access under
the vehicle.

(1) Position track assembly with proper number of shoes in a line in front or rear of vehicle. Align track
guides of track assembly between first pair of road wheels. If track shoes came in sections of five or
eight track shoes, connect 63 track shoes together for the left of the carrier (all except
M548A1/M548A3) and 64 track shoes for the right side of the carrier (all except M548A1/M548A3). For
the M548A1/M548A3, make sure you have 66 track shoes for both left and right.
(2) Remove two end connectors from track shoes, to be joined together..

ASSEMBLY – Continued

(3) Unblock vehicle (see your -10).

(4) Have helper drive vehicle forward or reverse until track assembly positions on sprockets.
(5) Have helper drive vehicle forward or reverse until track assembly is over idler wheels.
(6) Hold track in position using crowbar. Hook track fixture to end connectors on either side of break.
Install outside track fixture first, then install fixture to the inside of the track assembly.
(7) Tighten two track fixtures evenly until ends of track are close enough to install end connectors.

ASSEMBLY - Continued

(8) Place alignment track pin tool (12474881) over one pin on the outside track shoe and rest it on the
other pin. Tighten both track fixtures evenly to pull the track assembly together until the alignment track
pin tool fits over and seats fully on both track shoe’s pins. Install the second alignment track pin tool
on the inside track shoe pins.
(9) Remove the outside track fixture. Both alignment track pin tools will hold the track together. Leave
the other track fixture on the inside of the track shoe.

Figure 6. Install T150F Track Assembly on Vehicle

WARNING

Do not use a crowbar on the track shoe pins to get leverage. Any
scratches may cause the pin to break and cause the track assembly to
fall off the vehicle while operating. This may kill soldiers and damage
equipment. Use crowbar as shown in the following steps to get leverage
to install the end connectors.

NOTE

Place end connector or similar size block on top of the two track shoes
being joined. Use the crowbar under the track fixture connected to the
inside track shoes end connectors and press down on the block/end
connector to get the right angle to install the end connector.

(10) Make sure the inside track fixture is tight enough to allow the helper to use the crowbar under it with
enough pressure to get the slight degree of angle between the two track shoes to allow installing
the outside end connector. Use end connector or block to get the angle needed to install the end
connector. Use end connector or block as leverage to get angle needed to install end connector.

WARNING

Always wear eye protection when using a hammer. Eye injury may result if
metal chips contact eyes.

(11) Install the end connector on the outside track shoe pins. Get the angle needed to allow the end
connector to fit on the track shoe pins. Using a hammer, tap on the end connector close to the
alignment track pin tool. Remove the alignment track pin tool from the outside of the track shoe.
Tap the end connector fully onto the track shoe’s pins. Drive end connectors flush with pin ends,
and install bolts on each end connector.

ASSEMBLY - Continued

(12) Install inside end connector. Only a slight amount or no leverage is needed to install the second
end connector if the outside end connector is already installed.
(13) With the end connector installed half way on the inside of the track shoe, remove the track fixture
and alignment track pin tool. Finish installing the end connector flush with the pin ends.
WARNING

Not getting the bolt tight enough may result in death to personnel and
damage to equipment if the end connectors fall off during movement of the
vehicle. Torque each end connector bolt to the proper torque of 400-430 lb-
ft(543-583 Nm).
NOTE

Mark the location of the end connectors so they can be torqued properly.

(14) TORQUE END CONNECTORS’ BOLTS TO 400-430 lb-ft (543-583 N m). Make sure to check
every end connector bolt on the complete track assembly, even if it came in as a complete
assembly.
(15) Repeat installation procedures to the opposite side of the vehicle.
(16) Adjust track tension (see your -10).
f. Install T150F Spare Track Shoes and Brackets on vehicle (Figure 9).

M901A1, use four screws (B1821BH050C350N).
(2) Install two track shoes (12474844-1) on two brackets and secure with four square flat washers
(12474863), flat washers (MS27183-18), and screws (B1821BH050C125N).

FINAL INSPECTION

Final Inspection for T150F Track.

1. Adjust track tension (see your -10).

2. Verify ALL end connector bolts have been secured and torqued to 400-430 lb-ft (543-583 N m).

3. If final inspection is complete and correct, perform FOLLOW-THROUGH STEPS.

FOLLOW-THROUGH STEPS

1 Unblock vehicle (see your -10).

2. Road test vehicle to check that track is installed correctly (see your -20).

WARNING

Not getting the bolt tight enough may result in death to personnel and
damage to equipment if the end connectors fall off during movement of the
vehicle. Torque each end connector bolt to the proper torque of 400-430 lb-
ft(543-583 Nm).

3. CRITICAL SAFETY ITEM CHECK: After 30 to 60 miles of operation with new track, check torque on all
end connector bolts. TORQUE TO 400-430 lb-ft (543-583 N m).

4. CRITICAL SAFETY ITEM CHECK: After 1500 miles of operation with new track reverse track (see your -
20). This extends the life of the track. Keep a record of when track is installed/reversed.
