CONTROL VALVE BODY
Precaution
(1) Pay close attention when handling the control valve because it consists of the most precise and
delicate parts of the transaxle.
(2) Neatly arrange the removed parts in order to avoid mixing up similar parts.
(3) Disassemble the control valve assembly and thoroughly clean it when the clutch and/or brake
bands are burned, and/or when the automatic transaxle fluid is degenerated.
Disassembly
Disassemble in the sequence shown in the figure.

6. Install the thrust washers and side gears into the
gear case at the same time, then turn them back
on the pinion gear and align them with the pinion
shaft hole.
7. Check and adjust the backlash of the side gears
and pinion gears as follows:
(1) Install the left and right driveshafts in the
differential assembly.
(2) Support the driveshafts on V-blocks.
(3) Measure the backlash of both pinion gears.
Backlash:
Standard 0.025—0.1 mm (0.001—0.004 in)
Maximum 0.5 mm (0.020 in)
8.
If
the backlash is not within specification, place the
differential assembly.
