5-SPEED ISUZU MANUAL TRANSAXLE
5. Install the differential assembly first, then install
the input and output shaft with the 3rd/4th shift
fork and shaft together as an assembly into the
clutch housing. Make sure the lock pin is in the
3rd/4th shifter shaft before installing.
The 3rd/4th shift shaft is installed into the raised
collar of reverse shift lever bracket.
6. Install the 1-2 shift fork onto the synchronizer
sleeve and insert the shift shaft into the reverse
shift lever bracket. Align hole in fork with the
shaft and install a new double roll pin. Stake the
roll pin after installation.
7. Install reverse lever on shift bracket.
8. Install reverse and 5th gear shifter shaft and at
the same time, engage reverse shaft with reverse
shift lever. Make sure lock pin is in the 5th gear
shifter shaft before installing.
9. Install the reverse idler shaft together with the
gear into the clutch housing. Make sure reverse
lever is engaged in collar of gear.
10. Measure and determine shim size using J 33373:
A. Position the outer bearing races on the
input, output and differential bearings.
Position the shim selection gages on the
bearing races as shown in Figure 39. The
3 gages are identified: Input, Output and
Differential.
B. Place seven spacers provided with
J 33373 evenly around the perimeter of
the clutch housing (Figure 40).
C. Install bearing and shim retainer on trans-
axle case. Tighten screws to 17 N*m (13
lbs. ft.). After final torque on screws,
stake screws to the retaining plate.
D. Carefully position the transaxle case over
the gages and on the spacers. Install the
seven bolts provided with the tool kit and
tighten bolts alternately until case is
seated on spacers. Tighten bolts to 15
Nnn (10 lbs. ft.).
E. Rotate each gage to seat the bearings.
Rotate the differential case through three
revolutions in each direction.
F. With the three gages compressed, mea-
sure the gap between the outer sleeve and
the base pad using available shim sizes
(Figure 41). The input shaft shim should
be two sizes smaller than the largest shim
that will fit in the gap. The differential
should use a shim three sizes larger than
that which will smoothly fit in the gap.
The output shaft should use the largest
shim that can be placed into the gap and
drawn through without binding.
G. When each of the three shims has been
selected, remove the transaxle case, seven
spacers and three gages.
