NOTICE
Install stop assembly (13) with the large inside diameter toward the
front of the track roller frame.

NOTICE
Do not damage the threads on the inside of the front track roller frame
when the recoil spring is installed.
1. Attach a suitable lifting device to recoil spring (12) and stop assembly (13). The weight of
recoil spring (12) and stop assembly (13) is approximately 522 kg (1150 lb). Install recoil
spring (12) and stop assembly (13) in the front track roller frame.
2. Use a suitable lift truck to install recoil spring (12) and stop assembly (13) into the front
track roller frame.
3. Use Tooling (C) to install bearing (11) in pilot assembly (10) if the bearing was removed.
The inside diameter of the bearing must be 101.100 ± 0.116 mm (3.9803 ± .0045 inch) after
installation.
Note: The recoil spring and the stop assembly must be against the end of the front track
roller frame before pilot assembly (10) is installed.
4. Install pilot assembly (10) in the front track roller frame.

5. Attach a suitable lifting device to recoil spring retainer (9). The weight of recoil spring
retainer (9) is approximately 55 kg (120 lb). Install recoil spring retainer (9) in the front
track roller frame.
6. Tighten recoil spring retainer (9). Use Tooling (D) to tighten recoil spring retainer (9)
enough to contact the pilot assembly. Recoil spring retainer (9) must be installed
approximately 89.0 mm ( 3.50 inch).
Use only the tooling and cylinder listed in this procedure. Do not use
other cylinders because they can cause enough force to break the
tension rods. This can result in personal injury or death.
7. Install Tooling (B). Measure the distance between Surface (C) and 5P-7269 Plate (5) at four
locations next to 5P-2678 Studs. Use 2J-3505 Nuts (7) in order to adjust the plate. Adjust
the distance to 550.0 mm (21.65 inch). Install stops (2) on 5P-2678 Studs (6) to aid in
proper alignment for installation.

The recoil spring must never have more than 12.7 mm (.50 inch)
distance between the recoil spring retainer during installation of the
recoil spring.
8. Slowly extend the cylinder rod in order to compress the recoil spring while recoil spring
retainer (9) is installed. Continue this procedure until the outside of the recoil spring retainer
is 3.0 mm (0.12 inch) inside the front track roller frame.
9. Turn recoil spring retainer (9) until the slots are in alignment. Install stops (2) in the front
track roller frame.
10. Remove Tooling (B) from the front track roller frame.

11. Put stops (2) in position, and install four bolts (1) .
12. Fasten a suitable lifting device to track adjuster (4). Install track adjuster (4) in the front
track roller frame. The weight of track adjuster (4) is approximately 177 Kg (390 lb).
13. Put cable (3) in position on track adjuster (4). Install the spacer, the washer and the bolt that
keeps the cable in place.
End By: Install the front track roller frame. Refer to Disassembly and Assembly, "Track Roller
Frame (Front) - Install".
