Flex Plate: Service and Repair

CAUTION:
^ Driveplate installation must include a careful alignment as described by the procedure and specifications below.
^ Improper alignment can cause the driveplate to crack
^ Before installing the engine, make sure there is a pilot bushing in the end of the crankshaft. If not, one must be installed first, before installing the driveplate.
^ Replacement short blocks are supplied WITHOUT a pilot bushing.

- Install crankshaft holding tool 3242, refer to Engine.





- Mark positions of shim -1-, washer -2- and driveplate, relative to crankshaft.

CHECKING CLEARANCE

CAUTION: Part numbers are listed for reference only. Always check with your Parts supplier for the latest information.

- Install driveplate with shim -1-, using one of two available thicknesses, and washer -2-.
- Shim -1-, Part No. 054 105301, or equivalent: 3 mm (0.118 inch)

Vehicles with 01N transmission:
- Dimension -a-: 21.3-22.9 mm (0.839-0.902 inch)
If clearance is not correct, install different size shim(s) as necessary.
