Using a dial indicator and 2 V-blocks, measure the shaft runout.

Maximum runout:

0.015 mm (0.0006 in.)

УКАЗАНИЕ:

If the runout exceeds the maximum, replace the input shaft.

Using a micrometer, measure the outer diameter of the input shaft journal surface at the locations indicated.

Outer diameter:

Part	New shaft: mm (in.)	Minimum outer diameter: mm (in.)
A	21.991 to 22.006 (0.8658 to 0.8664)	21.991 (0.8658)
B	24.885 to 24.900 (0.9797 to 0.9803)	24.885 (0.9797)
C	28.991 to 29.006 (1.1414 to 1.1420)	28.991 (1.1414)
D	30.985 to 31.000 (1.2199 to 1.2205)	30.985 (1.2199)

УКАЗАНИЕ:

If the outer diameter is less than the minimum, replace the input shaft.

Using a cylinder gauge, measure the inside diameter of the 4th gear.

Inside diameter:

New gear: mm (in.)	Maximum inside diameter: mm (in.)
34.015 to 34.031 (1.3392 to 1.3398)	34.031 (1.3398)

УКАЗАНИЕ:

If the inside diameter exceeds the maximum, replace the 4th gear.

Using a cylinder gauge, measure the inside diameter of the 3rd gear.

Inside diameter:

New gear: mm (in.)	Maximum inside diameter: mm (in.)
36.015 to 36.031 (1.4179 to 1.4185)	36.031 (1.4185)

УКАЗАНИЕ:

If the inside diameter exceeds the maximum, replace the 3rd gear.

Check for wear and damage.

Coat the 4th gear cone with gear oil.

Turn the synchronizer ring in one direction while pushing it against the 4th gear cone.

Check that the ring locks.

УКАЗАНИЕ:

If the synchronizer ring does not lock, replace the ring or 4th gear.

Using a feeler gauge, measure the clearance between the 4th gear synchronizer ring back and 4th 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 4th gear synchronizer ring.

Check for wear and damage.

Coat the 3rd gear cone with gear oil.

Turn the synchronizer ring in one direction while pushing it against the 3rd gear cone.

Check that the ring locks.

УКАЗАНИЕ:

If the synchronizer ring does not lock, replace the ring or 3rd gear.

Using a feeler gauge, measure the clearance between the 3rd gear synchronizer ring back and 3rd gear spline end.

Standard clearance:

0.65 to 1.75 mm (0.0256 to 0.0689 in.)

УКАЗАНИЕ:

If the clearance is out of specification, replace the 3rd gear synchronizer ring.

Check the sliding condition between the No. 2 transmission clutch hub and No. 2 transmission hub sleeve.

Check that the spline gear's edges of the No. 2 transmission hub sleeve are not worn down.

Using vernier calipers, measure the width of the No. 2 transmission hub sleeve groove (B) and the thickness of the claw part on the No. 2 gear shift fork (A), and calculate the clearance.

Standard clearance (B - A):

0.15 to 0.35 mm (0.0059 to 0.0138 in.)

УКАЗАНИЕ:

If the clearance is out of specification, replace the No. 2 transmission hub sleeve and No. 2 gear shift fork.
