holding fixture base J–3289–20 mounted on the end
of a work bench.

5. Remove the drain plug from the transmission case
and drain the lubricant.
220RS053
6. Remove the speedometer driven gear assembly,
using a 10 mm wrench to remove the clamp bolt.
Pull out the sleeve/gear.
7. Position the offset lever(3) in the “3–4” neutral
position.
NOTE: Removal of the offset lever in a position other than
“3–4” may result in driving a roll pin(1) into the
detent/guide plate without releasing the lever(3) from the
shift shaft. Further disassembly will be difficult if this
occurs.
8. Using a 3/16–inch diameter pin punch and a hammer,
remove the offset lever roll pin(1) attaching the offset
lever to the shift shaft.

MANUAL TRANSMISSION
9. Remove the 8 bolts that hold the extension housing to
the case, using a 15 mm wrench.
Note that two bolts use sealer.
Separate the extension housing assembly(2) from
the case and shift cover. The offset lever(3) will also
separate from the shift shaft.
NOTE: Do not attempt to remove the offset lever while
the extension housing is still bolted to the case. The lever
has a positioning lug which engages the detent/guide
plate and prevents moving the lever far enough to remove
it.
220RW059
10. Remove the offset lever(3) from the extension
housing, along with the detent ball(3) and spring(3).
Remove the roll pin(1) from either the offset lever or
extension housing.

11. Carefully pry the oiling funnel(4) from the rear of the
counter shaft. This may be a very snug fit, and the
funnel may become damaged during removal unless
extreme care is used.
226RS097
12. Remove the 10 bolts that hold the shift cover to the
case, using a 10 mm wrench.
NOTE: Two of the shift cover bolts are also alignment
dowels. Note the location of these bolts for assembly.
Remove the shift cover assembly(5) from the case by
sliding it sideways toward the drain plug side of the
case for a distance of 1 inch. Then lift the cover
straight up from the case. You may need to break the
sealer bond between the cover and case before you
can separate them.

pliers.
