6.
Inspect inside edge of friction surface toward center of flywheel for a chamfer.
^
If flywheel does not have a chamfer, then a chamfer must be machined into flywheel. Refer to the "Flywheel Chamfering" procedure listed in
this bulletin.
^
If flywheel does have a chamfer and all other inspection procedures are within specification with no flywheel damage evident, then flywheel
does not need to be replaced.
Flywheel Chamfering Procedure
A flywheel is a precision machined part. It must be properly machined to provide effective performance. The flywheel may be taken to a machine shop
for machining, or may be machined at a Saturn retail facility using an adapter set on a brake lathe.
^
If your Saturn retail facility is equipped with an Accu-turn (TM) Brake Lathe, it is necessary to order an Accu-turn (TM) Flywheel Adapter Set. Call
Dealer Equipment at (800) GM-TOOLS (800 468-6657) to order an Accu-turn TM Flywheel Adapter Set (P/N 54-436057).
^
If your Saturn retail facility is equipped with an Ammco(R) Brake Lathe, the accessories needed for creating a chamfer on the flywheel should be
included. The Ammco(R) Brake Lathe offers no provision for measuring depth of cut. The depth of cut can be measured using a dial indicator.
^
If your Saturn retail facility is equipped with a brake lathe other than the two manufacturers mentioned above, contact that in an manufacturer's's
representative for the necessary flywheel machining accessories.
1.
Remove clutch cover, clutch disc, and flywheel according to procedures in the appropriate year Manual Transaxle Service Manual.
2.
Measure and mark the flywheel in the area to be machined. Measure 60 mm-64 mm (2.4-2.5 in.) starting from the outside edge of the flat portion
of the flywheel moving towards the inside edge of the flywheel. The material to be removed is from the inside edge of the flywheel to the
measured mark.
