start by: a) remove track roller framesb) remove track adjusters
Do not remove the front cover for the recoil springs until Step 4 is completed.
1. Remove cover (1). 2. Remove bolt and washer (2). 3. Tighten nut (3) until the springs are under compression.4. Make sure there is no tension against the front cover for the recoil springs by the following method. Loosen the bolts a little at a time. Remove the bolts. 5. Remove front cover (4) for the recoil spring. Weight of the front cover is 45 lb. (20.4 kg). Remove the O-ring seal from the front cover. 6. Use tool (A) to remove seal (5).7. Remove the snap ring and bearing (6). 8. Install a 5/8"-11NC forged eyebolt into the recoil spring pilot. Use a hoist for assistance in removal of recoil spring (7). Weight is 625 lb. (283.5 kg). Measure the length of the recoil springs under compression if they are to be disassembled. The same length will be needed for installation.Install Recoil Springs
1. Fasten a hoist to the recoil spring. Put the recoil spring (1) in position in the track frame. 2. Install the snap ring in the front cover. Install the bearing in the cover with tooling (A). Make sure the bearing is even with the snap ring. Install the seal in the front cover with tooling (B). Install the seal with the lip toward the outside of the front cover. Install the O-ring seal on the cover. 3. Put the front cover (2) in position on the recoil spring housing. Make sure the drain plug is at the bottom. Install the bolts that hold the cover to the recoil spring housing. 4. Loosen nut (3) until the rear face of the nut is .062 in. (1.57 mm) past the end of the bolt. 5. Install washer and bolt (3) that hold the nut in position. 6. Install cover (4).end by: a) install track adjustersb) install track roller framesDisassemble Recoil Springs
start by: a) remove recoil springs
The recoil springs are assembled under a force of several tons. This force is released against legs (C) during disassembly. Caution must be used to make sure the correct tooling is used and the correct procedure is followed.
1. Fasten a hoist to the recoil springs. Install the springs into tooling (A) as follows: a) Put plate (D) in position on the recoil springs. Install legs (C) through the holes in plate (D).b) Put plate (G) in position on the rear of the springs and install nuts (B). Put the springs so the centers of pilots (5) and (8) are in alignment with the centers of plates (G) and (D), respectively. Tighten nuts (B).c) Make an adjustment to nuts (J) so the distance between plates (G) and (D) is the same on all three legs (C) to prevent twisting of the spring.d) Put cylinder group (K) in position on plate (E). Install two bolts (H) and spacers that hold the cylinder group to plate (E). Put plate (E) in
