U N I Q U E S E R V I C E P R O C E D U R E S

Crankshaft Rear Seal Dust Cover

• There is a metal plate pressed onto the
primary flange of the crankshaft.
• This plate acts as a dust shield for the rear
seal and the mounting surface for the
flexplate/flywheel.
• The plate must be removed before the rear
cover can be removed.
• It can be removed with a common "finger
type" gear puller.

Crankshaft Primary Flange

• The crankshaft primary flange is bolted to
the rear of the crankshaft and it provides the
sealing surface for the rear seal.
• The flange is machined after being bolted to
the crankshaft.
• Note: Do not remove the six bolts in the
primary flange. If the bolts are removed
the crankshaft will have to be replaced or
repeated seal damage will occur.
