J TRANSMISSION Thrust lock washer 1. lnstall the synchronizer ring and 5th gear. 2. Insert the steel ball and thrust lock washer. 3. lnstall only the two 3.0mm I0.118 in) thick C-washers in the front mainshaft groove. 4. Push the C-washers fully toward 5th gear and measure the clearance between the thrust lock washer and C-washers. If the clearance is not as specified, select the proper thrust lock washer. Standard play: 0.1 -4.3mm {O.OO4--O.Ol2 in) Thrust lock washer thickness: 6.2mm (0.244 in), 6.4mm (0.252 in}, 6.5mm (0.256 in), 6.6mm (0.260 in} 5. lnstall the retaining ring. Mainshaft rear bearing 1. lnstall the rnainshaft rear bearing by using the SST, and fully seat it against the front C-washers. 2. lnstall the original C-washers and hold them with the retaining ring. 3. lnstall the washer and new snap ring. u 4. If the C-washers do not fit into the rear mainshaft groove, select the proper thickness C-washers. 5. Verify that both C-washers at one position are the same thickness. 6. With points @ through 0 pressed tightly together, mea- sure the clearance between the washer and snap ring. If the clearance is not as specified, select the proper C- washers. Standard play: 0-0.lmm (0-4.004 in) C-washer thickness: 2.9mm (0.114 in), 3.0mm (0,118 in), 3.1 mm (0.1 22 in), 3.2mm (0.1 26 in) Countershaft rear bearing lnstall the countershaft rear bearing onto the counter- shaft by using the SST.
