SCREW 8F5755 - Caterpillar

Procedure To Set Tapered Roller Bearings
1. Trunnions, with cones in place, should be installed in the pump body. See the Service Manual, Disassembly and Assembly, SENR2458.2. Install O-ring to one cover assembly.3. Install the swashplate assembly and cover assembly to the body using a .38 mm (.015") shim pack and torque the bolts to 43 N m (32 lb ft). Lay the motor on its side so that this cover assembly faces down.4. Install the other cover assembly without the O-ring and shims.
Illustration 1. Location of bolts.5. Torque four bolts (see Illustration 1) to 4.5 N m (40 lb in) total. Do not apply total torque to one bolt before tightening others. Torque in increments of 1 N m (10 lb in) while proceeding from bolt to bolt in a clockwise fashion [total of 1 N m (10 lb in) on (A), then (B), (C) and (D); then total of 2 N m (20 lb in) on (A), the (B) etc.] while tightening the bolts, move swashplate between stops.6. Measure the gap at two places 180° apart [Ref. (E) and (F)] with a feeler or tapered gauge.
Illustration 2. Gap between cover and body.7. Use a shim pack equal to the average gap minus .13 mm (.005"). [If this shim pack is between .13 mm and .64 mm (.005 and .025")] proceed to Step "8". If not, the total of this shim pack and the .38 mm (.015") pack used in Step 3 must be divided equally between the two cover assemblies. If no gap is obtained in Step 6, remove shim pack installed in Step 3 and repeat Steps 4 through 7.8. Remove the cover assembly used in Steps 4 through 7. Using the O-ring and shim pack determined in Step 7, install the cover assembly to the body and torque bolts to 43 N m (32 lb ft).
