Input Shaft
WARNING: This page is about a different variant/trim than selected.
- Inspect 3rd (2), 4th (3), and 6th gear (1) for axial clearance. Lift up on the gear from the settled position and measure travel. Refer to Transmission Clearance Specifications , Gear Axial Clearance table.
- Measure the radial clearance for each of the speed gears.
- Place the speed gear, with the needle roller bearing, on the input shaft at the correct journal.
- Use J 8001-3 or J 26900-12 (1) and J 26900-13 (2). See Special Tools .
- Position J 8001-3 or J 26900-12 on the gear. See Special Tools .
- Move the gear up and down.
Specification:
- Standard Clearance 1st gear: 0.02-0.073 mm (0.0008-0.0029 in)
- Standard Clearance 2nd and 3rd gear: 0.015-0.068 mm (0.0006-0.0027 in)
- Maximum Clearance 1st gear: 0.160 mm (0.0063 in)
- Maximum Clearance 2nd and 3rd gear: 0.160 mm (0.0063 in)
- If the clearance exceeds the maximum, replace either the gear, the needle roller bearing, or the input shaft.
- Clean the input shaft in a suitable solvent.
- Clean and air dry the oil gallery.
- Inspect the input shaft bearing surfaces for the following conditions:
- Wear
- Lack of lubricant
- Debris embedded in the oil grooves
- Brinelling
- Inspect the input shaft splines for wear or damage.
- Replace the input shaft if any of the above conditions are found.
- Using J 8001-3
or J 26900-12
(1), J 26900-13
(2) and V-blocks, inspect the input shaft for runout. See Special Tools .
Specification: Maximum runout: 0.06 mm (0.0024 in)
- If the runout exceeds the maximum, replace the input shaft.
- Using a micrometer, measure the diameter of the input shaft journals.
Specification:
- Minimum diameter 1st gear (a): 38.860 mm (1.5299 in)
- Minimum diameter 2nd gear (b): 46.860 mm (1.8449 in)
- Minimum diameter 3rd gear (c): 37.869 mm (1.4905 in)
- If the journal diameter is less than the minimum, replace the input shaft.
IMPORTANT:
To calculate the radial clearance, measure shaft diameter, needle roller bearing diameter and gear inner diameter.
