With Automatic Transmission See: Transmission and Drivetrain/Flex Plate/Service and Repair
With Manual Transmission See: Transmission and Drivetrain/Flywheel>
Important: Do not nick the crankshaft sealing surface when removing the seal.
2. Insert a flat-bladed or similar tool through the dust lip at an angle.
3. Pry the crankshaft rear oil seal out by moving the handle of the tool towards the end of the crankshaft.
4. Repeat, as necessary around the crankshaft rear oil seal, until the seal is removed.
Installation Procedure
Notice: Do not apply or use any oil lubrication on the crankshaft rear oil seal, or the seal installer. Do not touch the sealing lip of the oil seal once the
protective sleeve is removed. Doing so will damage/deform the seal.
Notice: Clean the crankshaft sealing surface with a clean, lint free towel. Inspect lead-in edge of crankshaft for burrs/sharp edges that could damage
the rear main oil seal. Remove burrs/sharp edges with crocus cloth before proceeding.
Important:
Notice: the direction of the rear oil seal. The new design seal is a reverse style as opposed to what has been used in the past. "THIS SIDE OUT"
has been stamped into the seal, as shown in the graphic.
1. Carefully remove the protection sleeve from the NEW crankshaft rear oil seal.
2. Install the crankshaft rear oil seal onto the J34686 by sliding the crankshaft rear oil seal over the mandrel using a twisting motion until the back of
the crankshaft rear oil seal bottoms squarely against the collar of the tool.
