(AA) Center pin (BB) Pistons (CC) Spring (DD) Bearing AssemblyDimension (A) ... 53.00 + 0.00 − 0.05 mm (2.087 + .000 − .002 inch)Dimension (B) with rotating group in housing ... 0.20 to 0.30 mm (.008 to .012 inch)Maximum clearance for dimension (C) between the snap ring and the spacer is 0.05 mm (.002 inch). (1) Install piston rings (2) and (3) with the marks on the indicated surfaces. (4) Torque for the bearing preload ... 31.5 1.0 N m (23 1 lb ft)Note: A used bearing that has been oiled should be torqued at 15.8 0.5 N m (11.60 .40 lb ft).Note: Measure the torque for the bearing preload in the fixture. Measure the torque for the bearing preload without pistons (BB) and center pin (AA). Measure the torque for the bearing preload before the bearings are pressed into the housing. (5) Torque for the fourteen screws ... 21 6 N m (15.5 4.4 lb ft)Note: Apply 4C-4030 Thread Lock Compound to the threads prior to tightening. (6) 145-8434 Spacer Thickness ... 3.15 mm (.124 inch) (7) 145-8435 Spacer Thickness ... 3.2 mm (.13 inch) (8) 145-8436 Spacer Thickness ... 3.25 mm (.128 inch) (9) 145-8439 Spacer Thickness ... 3.3 mm (.13 inch) (10) 145-8440 Spacer Thickness ... 3.35 mm (.132 inch) (11) 145-8441 Spacer Thickness ... 3.4 mm (.13 inch) (12) 145-8442 Spacer Thickness ... 3.45 mm (.136 inch) (13) 145-8443 Spacer Thickness ... 3.5 mm (.14 inch)After you apply the bearing preload of 31.5 1.0 N m (23 1 lb ft), use spacers (6) through spacers (13) in order to adjust dimension (C) . (14) 145-8429 Shim Thickness ... 4.80 mm (.189 inch) (15) 145-8430 Shim Thickness ... 4.85 mm (.191 inch) (16) 145-8431 Shim Thickness ... 4.90 mm (.193 inch) (17) 145-8432 Shim Thickness ... 4.95 mm (.195 inch) (18) 145-8433 Shim Thickness ... 5.0 mm (.197 inch)Use shims (14) through shims (18) in order to adjust for dimension (A) . (19) 145-8452 Shim Thickness ... 5.5 mm (.22 inch) (20) 145-8453 Shim Thickness ... 5.6 mm (.22 inch) (21) 145-8454 Shim Thickness ... 5.7 mm (.22 inch) (22) 145-8455 Shim Thickness ... 5.8 mm (.23 inch) (23) 145-8456 Shim Thickness ... 5.9 mm (.23 inch) (24) 145-8457 Shim Thickness ... 6.0 mm (.24 inch)Use shims (19) through shims (24) in order to adjust for dimension (B). Dimension (B) must be maintained at numerous displacements. Dimension (B) may be achieved by selecting shims of several thicknesses.
