Input Shaft: Disassembly
CAUTION:
When pressing off components, hold the shaft so that it does not fall.
- Measure the input shaft clearances.
- Measure the clearance between the third and second gears.
- Measure the clearance between fourth gear and the bearing cone.
- Use an (A) arbor press, (B) Shaft Protector, and (C) Bearing Pulling Attachment to press off the (D) bearing (fourth gear end).
- Remove fourth gear and the synchronizer blocking ring.
- Remove the snap ring.
- Use an (A) arbor press, (B) Shaft Protector, and (C) Pinion Bearing Cone Remover to press off the (D) synchronizer hub assembly, (E) synchronizer blocking ring, and (F) third gear.
- Use an arbor press, (A) Shaft Protector, and (B) Bearing Pulling Attachment to press off the (C) bearing (third gear end).
- Use Dial Indicator/Magnetic Base to measure input shaft gear runout.
- Inspect the input shaft for worn or damaged gears.
- Inspect the synchronizer blocking rings.
- Measure the clearance from the side of the gear.
- Inspect for smooth engagement with the gear.
- Inspect for worn or damaged teeth or tapper surface.
- Inspect the synchronizer hub.
- Inspect for worn or damaged splines, synchronizer insert groove or end surface.
- Inspect for smooth hub sleeve movement when it is installed.
- Measure the clearance between the third/fourth synchronizer hub and its shift fork.
CAUTION:
The synchronizer blocking rings are not interchangeable. Be sure to keep them in the order that they were removed.
