COMPONENT PARTS
GENERAL NOTES
The instructions here are organized so that you work on only one component group at a time.
This will help avoid confusion from similar±looking parts of different subassemblies being on your work-
bench at the same time.
The component groups are inspected and repaired from the converter housing side.
As much as possible, complete the inspection, repair and assembly before proceeding to the next com-
ponent group. If a component group cannot be assembled because parts are being ordered, be sure
to keep all parts of that group in a separate container while proceeding with disassembly, inspection,
repair and assembly of other component groups.
Recommended fluid for the automatic transaxle:
DEXRON ® @@@@@: [g 2]
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean and any fluid passages and holes blown through with
compressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent accidentally spray-
ing automatic transmission fluid or kerosene in your face.
3. The recommended automatic transaxle fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in the correct order to allow efficient inspection, repairs,
and reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corresponding spring.
3. New brakes and clutches that are to be used for replacement must be soaked in transaxle fluid for at
least 15 minutes before assembly.
GENERAL ASSEMBLY:
1. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with
transmission fluid prior to reassembly.
2. All gaskets and rubber O±rings should be replaced.
3. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed in the
groove correctly.
4. If a worn bushing is to be replaced, the subassembly containing that bushing must be replaced.
5. Check thrust bearings and races for wear or damage. Replace if necessary.
6. Use petroleum jelly to keep parts in place.

(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN±8).
Cancel the parking brake on the level place and
shift the transmission in Neutral (or N position).
When jacking up the front wheels of the vehicle at
first place stoppers behind the rear wheels.
When jacking up the rear wheels of the vehicle at
first place stoppers before the front wheels.
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind the other wheels on the ground.
After the vehicle is jacked up, be sure to support it
on rigid racks . It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a small job that can be finished quickly.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity.)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the elec-
tronic components, air filter and emission±related
components from water.
(6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(7) When checking continuity at the wire connector, in-
sert the tester probe carefully to prevent terminals
from bending.
(8) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step±down
adapter for adjustment. Once the hose has been
stretched, it may leak air.
