Remove Front Idlers
START BY:a) separation of tracks 1. Remove bolts (2) and guard (1) from each side of the front idler.2. Remove bolts (3), spacers (6), shims and plates (5) from each side of the front idler. Remove the two strips (4) from each side of the front idler. Keep the shims with their respective plates so they will not be mixed at assembly. 3. Remove bolts (8) from each side of the front idler.4. Fasten a hoist to the front idler. Remove bolt (7) from each side of the front idler.5. Move the front idler forward until the collars of the front idler are free from the track roller frame. 6. Remove front idler (9). Weight of the front idler is 227 kg (500 lb.).Install Front Idlers
1. Fasten a hoist to front idler (1). Put the front idler in position on the track roller frame. 2. Install bolts (5) that hold the front idler to the yoke.3. Install bolt (2) on each side of the front idler. Shims (3) are to give a minimum clearance of 0.76 to 1.91 mm (.030 to .075 in.) between the yoke and plate (4). Make adjustments to the amount of shims if necessary. 4. Put shims (6) and plate (7) in position on both sides of the front idlers. Shims (6) are to keep dimension (B) a distance of 0.76 to 0.51 mm (.030 .020 in.). 5. Install spacers (11), bolts (10) and strips (9) that hold plates (7) in position. Tighten bolts (10) to a torque of 270 35 N m (200 25 lb.ft.).6. Install guard (8) on both sides of the front idler.END BY:a) connection of trackDisassemble Front Idlers
