TM 9-2520-238-34 REPAIR COOLING FAN RIGHT ANGLE DRIVE C (M113A3 FOV ONLY) — Continued 0016 00 5. If tapered roller bearing (1) and roller bearing (2) must be replaced, press outer races of two new bearings into bearing retaining plate (3). Use arbor press. NOTE Take all measurements in thousandths of an inch. 6. Determine thickness of shim (4) as follows: a. Insert inner race of bearing (1) into outer race in retaining plate (3). Place retaining plate with inner race of bearing on clean, flat surface. Measure from top edge of inner race to surface. Record as dimension Z1. Use caliper set. b. Insert inner race of bearing (2) into outer race in retaining plate (3). Turn retaining plate over with inner race of bearing (2) on clean, flat surface. Measure from top edge of bearing (2) inner race to surface. Record as dimension Z2. Use caliper set. c. With inner races of bearing (1) and bearing (2) installed, measure and record total height of assembly as dimension X. Use caliper set. d. Measure and record length of sleeve spacer (5) as dimension Y. Use caliper set. e. Calculate shim thickness using above measurements as follows: Shim thickness = X −Y −Z1 – Z2 – 0.001 f. Peel new laminated shim (4) to calculated thickness or next thinner laminate. g. Remove inner races of bearing (1) and bearing (2) from retaining plate (3). 0016 00-9
