29.1a Transmission input shaft components

bearing are not available separately and the shaft itself must be renewed. Also remove and check the condition of the output shaft oil seal and renew it if it is worn or damaged (see illustration). Apply some grease to the lips of the seal on installation (see illustration).

Installation

5 On J and К models, if removed, fit the needle bearing cage for the input shaft into its hole in the crankcase, then fit the retainer and tighten the bolt securely. Apply some engine oil to the bearing, then fit the bearing into the cage. Slide the shaft into the crankcase. making sure the shaft end locates into the needle bearing and that the shaft is slid fully home. Install the bearing half-ring retainer for the left-hand end of the output shaft into its slot in the upper crankcase half. Lower the output shaft into position in the crankcase half, making sure the groove in the bearing engages correctly with the bearing half-ring retainer.

6 On L, N and R models, if removed, fit the needle bearing dowel into its hole in the upper crankcase (see illustration). Lower the input shaft into position, making sure it locates correctly onto the dowel (see illustration). Lower the output shaft into position, making sure it meshes correctly with the input shaft. and the locating ring around the bearing and the oil seal lip fit in the slot in the crankcase (see illustration 28.3).

7 Make sure both transmission shafts are correctly seated and their related pinions are correctly engaged.

Caution: If the bearing retainer or dowel are not correctly engaged with their bearings, the crankcase halves will not seat correctly.

8 Position the gears in the neutral position and check the shafts are free to rotate easily and independently (ie the input shaft can turn whilst the output shaft is held stationary) before proceeding further.

9 Reassemble the crankcase halves (see Section 21).

disassembly, inspection and reassembly

1 Remove the transmission shafts from the casing (see Section 28). Always disassemble the transmission shafts separately to avoid mixing up the components (see illustrations).
