HOSE BK 4568519 - Caterpillar

The track is removed from the right side of the machine for better illustration of tooling (B) position.
TYPICAL EXAMPLE1. Start the machine. Move the machine forward on tooling (A). 2. Put tooling (B) in position under the equalizer spring on both sides of the machine. 3. Move the machine backward up on tooling (A). Put tooling (B) in position under the steering clutch case.4. Tighten the track until it is against the track roller. Do not tighten the track too tight. Damage to the seals in the track adjusting mechanism can result. 5. Remove four bolts (2). Loosen the track. Lower roller (1) and remove it from under the track roller frame. The weight of the track roller is 85 lb. (39 kg).Install Track Rollers
1. Put the track roller (1) in position on the track.2. Tighten the track until the track roller is against the track roller frame.3. Install the four bolts. Tighten the bolts to a torque of 125 5 lb.ft. (170 7 N m).4. Put tooling (A) in front of the tracks. Start the machine. Move tracks forward up on tooling (A). Remove tooling (B) from both sides of the equalizer spring. Put tooling (A) at the rear of the tracks. Move machine backward up on tooling (A). Remove tooling (B) from under the steering clutch case. Move the machine forward off of tooling (A).5. Make an adjustment to the tracks. See TRACK ADJUSTMENT in LUBRICATION AND MAINTENANCE GUIDE.Disassemble Track Rollers
start by:a) remove track rollers1. Remove the plug from the end of the shaft. Remove the oil from the roller. 2. Install tooling (A) on roller (3). Put collar (2) under compression until ring (1) can be removed. Remove the ring from the shaft.3. Remove tooling (A) from the roller. Remove collar (2). Remove the O-ring seal from the shaft.4. Remove the Duo-Cone seal from the collar and bushing. Put identification on the seals to prevent mixing at assembly.5. Follow Steps 2 through 4 and remove the ring, collar, O-ring seal, and Duo-Cone seal from the other end of the roller. 6. Remove the six bolts (4) from each side of the roller.7. Remove the two bushings and shaft (5) from the roller with a press. See TRACK ROLLER SPECIFICATIONS in POWER TRAIN SPECIFICATIONS.
TYPICAL EXAMPLE8. Remove bushing (6) from bushings (8) with a press.9. Cut pins (7) off even with the bushing. Make the surface of the bushing smooth with a file.Assemble Track Rollers
1. Put the oil holes in the bushings in alignment. Install bushings (1) in bushings (3) with a press. Drill two .297 in. (7.54 mm) holes 180° apart .75 in. (19.05 mm) deep through bushings (1) and into bushings (3). Do not drill the holes through the lubrication grooves on bushings (1). Install two new pins (2) even with the outside face of bushings (1).
TYPICAL EXAMPLE2. Install the O-ring seals on the bushings. Put oil on the seals and contact surfaces of the bushings and roller. Install one of the
