HANDLING PRECAUTIONS
CAUTION:
-
Do not perform a stall test if there are any people or objects near the vehicle.
-
The vehicle could begin moving suddenly, resulting in a serious accident.
-
Do not perform a stall test if any wheel chocks are out of position.
-
The vehicle could begin moving suddenly, resulting in a serious accident.
-
Do not perform the stall test on a slippery or low-friction surface that could allow the tires to spin.
-
The vehicle could begin moving suddenly, resulting in a serious accident.
-
Do not blow compressed air without wearing safety glasses.
-
Automatic Transaxle Fluid (ATF) could enter your eyes, possibly resulting in blindness.
NOTICE:
-
The automatic transaxle assembly is composed of precision-made parts. Careful inspection before reassembly is necessary because even a small nick could cause fluid leakage or affect performance.
-
The procedures are organized so that you work on only one component group at a time. This will help avoid confusion with similar-looking parts of different sub-assemblies being on your workbench at the same time.
-
The component groups are inspected and repaired from the converter housing side.
-
Whenever possible, complete the inspection, repair and reassembly before proceeding to the next component group. If a defect is found in a certain component group during reassembly, inspect and repair this group immediately. If a component group cannot be assembled because parts are being ordered, be sure to keep all parts of the group in a separate container while proceeding with disassembly, inspection, repair and reassembly of other component groups.
-
Use of Toyota Genuine ATF WS is recommended.
-
All disassembled parts should be cleaned, and compressed air should be blown through any fluid passages and holes.
-
Dry all parts with compressed air. Never use a piece of cloth.
-
The recommended ATF or kerosene should be used for cleaning.
-
After cleaning, the parts should be arranged in the order they were removed for efficient inspection, repair and reassembly.
-
New brake discs and clutch discs must be soaked in ATF for at least 15 minutes before reassembly.
-
All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with ATF prior to reassembly.
-
All old gaskets and rubber O-rings must be replaced.
-
Do not apply adhesive cement to gaskets or similar parts.
-
Make sure that the ends of snap rings are not aligned with any cutouts. Make sure that snap rings are correctly installed into the grooves.
-
If a worn bushing is to be replaced, the sub-assembly containing the bushing must also be replaced.
-
Check the thrust bearings and races for wear or damage. Replace them if necessary.
-
Use petroleum jelly to keep parts in place.
-
When working with seal packing (FIPG), observe the following:
-
Using a razor blade and a gasket scraper, remove all of the old seal packing (FIPG) from the gasket surface.
-
Thoroughly clean all components to remove any seal packing (FIPG).
-
Clean both sealing surfaces with a non-residue solvent.
-
Parts must be reassembled within 10 minutes of application. Otherwise, the seal packing (FIPG) must be removed and reapplied.
