This page is from a factory service manual section titled "Repair for Component Parts," covering the Clutch Housing and Transmission Case (continued) of a manual transaxle. It describes servicing bearing outer races. For the mainshaft front bearing outer race: (1) use a puller with thinner pawls to avoid damaging the oil channel; (2) when installing a new oil channel, align its cut-out portion with the oil groove in the transmission case; (3) press the bearing outer race in with a drift. For the mainshaft rear bearing outer race, the reader is directed to the Mainshaft & Differential Side Bearing Preload Adjustment procedure. It also covers removal and installation of the differential side bearing outer race, illustrated with a drift/punch driving the race out of the case and a special tool pressing the new race in while the case rests on a wooden block. Five line-art illustrations (figure codes SMT902, SMT903, SMT943, SMT907, SMT908) accompany the text. The page is numbered MT-10, indicating the manual transaxle (MT) section. No torque values, part numbers, or model years appear on this page.
