Important: In all work involving disassembly of the transaxle, a new output shaft
nut and crush sleeve must be installed during reassembly.
- Remove the back-up lamp switch to prevent the switch from being
damaged during disassembly.
- Cover the holes for clutch hydraulics, axles, and the reverse
lamp switch, and clean the transaxle if necessary.
- Mount the transaxle on
holding J 43707
. Mount
the transaxle and fixture in the J 43964
.
- Remove the pipe from the
slave cylinder.
- Using pliers, pinch together
the bottom halves of the pipe sleeve and move the pipe and sleeve upward.
- Pry up the locking tabs
on the sleeve and remove the pipe.
- Remove the slave cylinder
bolts and slave cylinder.
- Remove the reverse idler gear shaft bolt with an O-ring.
- Remove the transaxle rear
cover and discard the gasket.
Important: Do not shift gears using the 1st/2nd, 3rd/4th, or 5th shift shafts.
All shifting should be done using the shift control shaft.
- Put the transaxle into 3rd gear by pulling the shift control shaft out.
Other gears can be selected as follows:
• | Even gears = push shaft in |
• | Odd gears = pull shaft out |
• | 1st/2nd shift gate = turn shaft counter-clockwise |
• | 5th and reverse gears = turn shaft clockwise. |
- Using a punch and hammer,
tap out the 5th gear fork retaining pin.
- Engage the 5th gear by
pressing the synchronizer sleeve and fork down onto the 5th gear. Two gears
must be engaged at the same time to allow removal of output shaft nut.
- Pry up the locking tab on the output shaft nut and remove the
nut.
Important: Before removing the 5th gear synchronizer sleeve, mark its position
relative to the 5th gear synchronizer hub to assist in assembly.
Important: Make sure the 5th gear shift shaft does not come out of the transaxle
when the 5th gear shift fork is removed.
- Remove the 5th gear shift fork and synchronizer sleeve together.
- Remove the 5th gear synchronizer
hub snap ring. This will be easier if the hub is tapped down first.
- Use the J 25031-A
to remove the 5th gear synchronizer hub.
- Remove the blocking ring, blocking ring spring, 5th gear, and
5th gear bearing assembly.
Important: When a manual transaxle with a serial number before T02075 is repaired
for a 5th gear synchronizer failure, it must be determined whether the
synchronizer components are of the 1st design or the 2nd design.
The illustrations show the 1st design, the left half of the illustration,
and the 2nd design, the right half of the illustration, of the 5th gear
synchronizer components.
Important: All transaxles built prior to the T02075 serial number will be of the
1st design unless they have been previously repaired for this condition.
All service parts are of the 2nd design.
- If the 5th synchronizer sleeve removed from the transaxle looks like
the sleeve on the left, then it is a 1st design. The identification mark
for the 2nd design is the extra groove on the top of the 5th gear sleeve.
- If the 5th gear blocking
ring removed from the transaxle does not have a part number embossed on
the bottom of the blocking ring, then it is a 1st design.
If either the 5th synchronizer sleeve or blocking ring is a 1st design and
needs to be replaced, then both the sleeve and the blocking ring must be
replaced with the 2nd design parts as a unit. If the blocking rings and
sleeve have already been replaced with the 2nd design components, then
only replace parts as needed.
- Remove the differential bearing retainer fasteners. The retainer will
be removed after case removal.
- Remove the case-to-reverse
idler gear shaft bracket bolt.
- Remove the case-to-clutch housing bolts and tap
down 2 case-to-clutch housing alignment sleeves.
- Remove the case from
the output shaft.
23.1. | Check that 3rd gear is engaged. |
23.3. | Install the 87 91 410
to the output shaft. |
23.4. | Install the 87 91 287
with the 87-91-303
into the pulling eyes. |
23.5. | Carefully tighten the puller until the output shaft bearing and
5th driven gear releases from the output shaft. |
- Remove tools. Lift off
transaxle case.
- Remove differential bearing retainer from transaxle case.
- Inspect the O-ring seal and axle seal for damage. Replace
if damaged.
Important: Do not re-install the bearing race until after the shimming procedure.
- Tap out differential bearing race using 87 92 202
and 87 91 204
.
- Remove the reverse gear
fork and shaft.
- Put the transaxle in 4th
gear by pushing the shift control shaft in.
- Remove the reverse shift lever assembly and bolts.
- Engage towards the reverse
gear on the shift linkage assembly to access the shift control shaft bolt.
Important: Make sure the TORX® socket fully engages the bolt prior to attempting
removal.
Important: Note the orientation of the shift shaft block.
- Remove the shift shaft bolt, the shift shaft, and the shaft block.
- Disengage the reverse
on the shift linkage assembly. Remove the remaining shift linkage bolt
and lift the mechanism slightly. Remove the locating sleeves.
- Put the transaxle in 2nd gear and remove the shift linkage assembly
by moving it rearward, towards the differential, and angling it out while
lifting.
- Lift the input shaft far
enough to allow removal of the reverse idler gear shaft assembly. Remove
the reverse idler gear shaft.
- Remove the 4th driven
gear, crush sleeve, and spacer sleeve from the output shaft.
- Install the 87 92 103
around the 1st gear and 1st/2nd gear synchronizer sleeve as shown. This
tool holds the 1st and 2nd synchronizer assemblies together. Secure the
tool with a plastic tie.
- Install the 87 91 410
on the output shaft.
- Install the 87 91 287
with the 87 91 295
under the 1st driven gear of the output shaft.
- Carefully tighten the puller until the remaining output shaft
gears are up far enough to allow the removal of the input shaft, approximately
15 mm (0.6 in).
- Remove the input shaft.
Important: Note the up/down orientation of the 3rd driven gear. If the old gear
is installed, it must be installed in the same orientation to avoid noise
concerns.
- Continue pulling the driven gears on the output shaft until all gears
are loose.
- Remove the puller and gears from the output shaft.
Notice: The output shaft bearing retainer bolts were installed using a threadlocker
at the factory. A J43483 impact driver or equivalent must be used to remove these
bolts or the bolt heads may strip out requiring additional repair time.
- Remove the output shaft bearing retainer bolts using the J 43483
or equivalent and remove
the retainer.
- Remove the output shaft
using the 87 91 188
,
the 87 91 972
, and the 87 91 261
.
- Remove the differential assembly.
