T350 MANUAL TRANSAXLEINPUT SHAFT
DISASSEMBLY
Fig.89 Input Shaft:
Before disassembly of the input shaft (1) (Fig. 89), it is necessary to check the synchronizer stop ring gap. Use a feeler gauge to measure the gaps between the stop rings (2,5 and 8) and the speed gears. The correct gaps are:
- 1st - 0.522 - 2.208 mm (0.021 - 0.087 inch)
- 2nd - 0.522 - 2.208 mm (0.021 - 0.087 inch)
- 3rd - 0.73 - 1.53 mm (0.029 - 0.060 inch)
- 4th - 0.77 - 1.57 mm (0.030 - 0.062 inch).
- 5th - 0.73 - 1.53 mm (0.029 - 0.060 inch)
- Reverse Brake - 0.505 - 1.74 mm (0.020 - 0.068 inch)
The reverse brake measurement is taken between the stop ring and case.
If a stop ring gap does not fall within the specifications, it must be inspected for wear and replaced. If the 1st or 2nd synchronizer stop ring is worn beyond specifications, the complete output shaft assembly must be replaced.
The input shaft incorporates the 3rd, 4th, and 5th speed gears and synchronizers on the assembly.
