Input Shaft: Disassembly

WARNING: This page is about a different car, the 2011 Mercury Milan and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Measure the input shaft clearances.
1. Measure the clearance between the 3rd and 2nd gears. Third gear thrust clearance is 0.05-0.20 mm (0.001-0.007 in).
2. Measure the clearance between 4th gear and the bearing cone. Fourth gear endplay is 0.17-0.37 mm (0.006-0.014 in).

NOTE: When pressing off components, hold the shaft so it does not fall.

NOTE: Use the Shaft Protector Set to prevent damage to the shaft.

Using the Bearing Puller and a suitable press, press off the bearing.
- Discard the bearing.
- Always install new bearings and cups as a set.

NOTE: The synchronizer blocking rings are not interchangeable. Make sure to keep them in the order that they were removed.

NOTE: Using a paint pen, mark the hub to sleeve position for reassembly.

Disassemble the synchronizer assembly.
1. Remove the synchronizer blocking spring.
2. Remove the opposite synchronize spring.
3. Remove the synchronizer hub inserts.
4. Separate the synchronizer hub from the sleeve.
- Inspect all synchronizer components for wear and damage. Install a new synchronizer as necessary.

Using the Bearing Puller and a suitable press, press off the bearing.
- Discard the bearing.
- Always install new bearings and cups as a set.
Using the Dial Indicator Gauge with Holding Fixture, measure the input shaft gear runout.
- Inspect the input shaft for worn or damaged gears. Install a new input shaft as necessary.
- Input shaft gear maximum runout is 0.05 mm (0.001 in).

Set the synchronizer ring set squarely on the gear, then measure around the circumference.
- Measure the clearance from the side of the gear.
  - Synchronizer ring clearance is 0.80-1.50 mm (0.031-0.059 in).
- Inspect for smooth engagement with the gear.
- Inspect for worn or damaged teeth. Install new components as necessary.

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 3rd/4th synchronizer hub and its shift fork.
- Shift fork and hub sleeve clearance is 0.10-0.90 mm (0.003-0.035 in).
