1. Measure the clearance between 1st gear (A) and
the 1st gear distance collar (B) with a feeler gauge
(C).
 If the clearance exceeds the service limit, go to step 2.
 If the clearance is within the service limit, go to step 4.
2. Measure the length of the 1st gear distance collar as shown.
 If the length is not within the standard, replace the 1st gear distance collar.
 If the length is within the standard, go to step 3. 3. Measure the thickness of 1st gear.
 If the thickness is less than the service limit,replace 1st gear.
 If the thickness is within the service limit, replace the 1st/2nd synchro hub and the reverse gear as
aset.
4. Measure the clearance between 2nd gear (A) and 3rd gear (B) with a feeler gauge (C). If the clearance
exceedstheservicelimit,gotostep5.

5. Measure the length of the 2nd gear distance collar.  If the length is not within the standard, replacethe 2nd gear distance collar.
 If the length is within the standard, go to step 6.
6. Measure the thickness of 2nd gear.  If the thickness is less than the service limit,replace 2nd gear.
 If the thickness is within the service limit, replace the 1st/2nd synchro hub and the reverse gear as
aset. NOTE: Refer to the Exploded View in the Countershaft
Reassembly, as needed, when removing components
pressed on to the countershaft (see page 13-44).
1. Securely clamp the countershaft assembly in a bench vise with wood blocks.
2. Remove the special bolt (left-hand threads).
3. Support the ball bearing (A) on steel blocks (B), then use a press (C) and an attachment (D) to press
the countershaft out of the ball bearing.
4. Removethe35mmshimandthedistancecollar.

5. Support 4th gear (A) on steel blocks (B), then use apress (C) and an attachment (D) to press the
countershaft (E) out of 4th gear and 5th gear.
6. Support 2nd gear (A) on steel blocks (B), then use a press (C) and an attachment (D) to press the
countershaft (E) out of 2nd gear and 3rd gear. 1. Inspect the gear and bearing contact areas for wear
and damage, then measure the countershaft at
points A, B, and C. If any part of the countershaft is
less than the service limit, replace it.
2. Inspect the runout by supporting both ends of the countershaft. Then rotate the countershaft two
complete turns while measuring with a dial gauge.
If the runout exceeds the service limit, replace the
countershaft.
