Check the sliding condition between the No. 3 transmission hub sleeve and No. 3 transmission clutch hub.

Check that the tip of the spline gear of the No. 3 transmission hub sleeve is not worn down.

Using vernier calipers, measure the width of the No. 3 transmission hub sleeve groove (A) and the thickness of the claw part on the No. 3 gear shift fork (B), and calculate the clearance.

Standard clearance (A - B):

0.31 to 0.89 mm (0.0122 to 0.035 in.)

УКАЗАНИЕ:

If the clearance is out of specification, replace the No. 3 transmission hub sleeve and No. 3 gear shift fork.

Check for wear or damage.

Coat the 6th gear cone with gear oil. Turn the synchronizer ring in one direction while pushing it against the 6th gear cone. Check that the ring locks.

УКАЗАНИЕ:

If the synchronizer outer ring does not lock, replace the ring or the 6th gear.

Using a feeler gauge, measure the clearance between the synchronizer ring back and gear spline end.

Standard clearance:

0.75 to 1.65 mm (0.0295 to 0.065 in.)

УКАЗАНИЕ:

If the clearance is out of specification, replace the No. 3 synchronizer ring (for 6th gear).

Using a caliper gauge, measure the 6th gear inner diameter.

Inner diameter:

New gear: mm (in.)	Maximum inner diameter: mm (in.)
28.015 to 28.031 (1.1030 to 1.1036)	28.031 (1.1036)

УКАЗАНИЕ:

If the clearance exceeds the maximum, replace the 6th gear sub-assembly.

Coat the 5th gear cone with gear oil. Turn the synchronizer ring in one direction while pushing it against the 5th gear cone. Check that the ring locks.

УКАЗАНИЕ:

If the synchronizer outer ring does not lock, replace the ring or the 5th gear.

Using a feeler gauge, measure the clearance between the synchronizer ring back and 5th gear spline end.

Standard clearance:

0.75 to 1.65 mm (0.0295 to 0.0650 in.)

УКАЗАНИЕ:

If the clearance is out of specification, replace the No. 3 synchronizer ring (for 5th gear).

Using a caliper gauge, measure the 5th gear inner diameter.

Inner diameter:

New gear: mm (in.)	Maximum inner diameter: mm (in.)
29.915 to 29.931 (1.1778 to 1.1784)	29.931 (1.1784)

УКАЗАНИЕ:

If the inner diameter exceeds the maximum, replace the 5th gear.

Using a caliper gauge, inspect the reverse idler gear sub-assembly as shown in the illustration.

Inner diameter:

New gear: mm (in.)	Maximum inner diameter: mm (in.)
18.040 to 18.058 (0.7102 to 0.7109)	18.058 (0.7109)

УКАЗАНИЕ:

If the inner diameter exceeds the maximum, replace the reverse idler gear sub-assembly.

Using a micrometer, inspect the reverse idler gear shaft as shown in the illustration.

Outer diameter:

New idler gear shaft: mm (in.)	Minimum outer diameter: mm (in.)
17.966 to 17.984 (0.7073 to 0.7080)	17.966 (0.7073)

УКАЗАНИЕ:

If the outer diameter is less than the minimum, replace the reverse idler gear shaft.
