Inspection

8. Using a 4 mm Allen key, lever speedometer drive gear retaining lugs out of differential casing.
9. Remove drive gear and retaining ring.

CAUTION: The following need only be carried out if bearings are to be renewed.

10. Clamp both halves of bearing separator around differential bearing.
11. Assemble tool 18G2 and thrust button tool 18G2/3 to differential.
12. Remove bearing using tool 18G2.
13. Carry out 10 to 12 for remaining bearing.

CAUTION: Drive gear and differential housing are a matched assembly, do not attempt to remove drive gear; if replacement is required, a new assembly must be fitted.

Inspection

CAUTION: Thoroughly clean all components; renew any component found to be damaged or worn. Components of matched assemblies must not be renewed individually. Matched assemblies are:- • Clutch housing and intermediate plate. • Selector lever and shaft. • Combined interlock and detent.

Check following for damage or wear:

• Splines and threads of input and output shafts.
• Plastic insert in end of output shaft.
• Teeth and splines of gears.
• Differential bearings.

CAUTION: If differential bearings are to be renewed, renew bearing outer tracks in gearbox casing and clutch housing. • Differential pinions and gears. • Pinion shaft. • Differential drive gear. • Speedometer drive and driven gears. • Thrust washers. • 5th speed gear needle bearing. • Bias spring and plastic cups. • Segment rings. • Selector shafts. • Synchro hubs and couplings. • Synchro hub fingers, balls and springs. • Synchro rings. • Rear cover gasket. • Clutch release bearing. • Reverse locking plunger and spring. • Combined interlock and detent assembly. • Reverse selector fork and lever assembly.

These components must be renewed during reassembly.

• Input shaft locknut
• Output shaft locknut
• Input and output shaft bearings
• Oil seals and ’O’ rings.
• Drive/roll pins.
