The front cover seal (behind the balancer) is a one-piece seal, as is the rear main (at flywheel end).

Directions for Front Seal Removal and Installation:

Removal

Remove drive belts. Remove pulley. Remove vibration damper retaining bolt. Using Damper Puller/Installer, remove vibration damper. Pry seal from cover with screwdriver. Do not damage front cover.

Installation

1. Using Seal Installer, install new seal in front cover. Seal lip must face toward engine. Coat seal lip with engine oil. Install vibration damper.

2. Before installing vibration damper retaining bolt, apply small amount of RTV sealant at crankshaft Woodruff key and vibration damper. Install retaining bolt and tighten to specification. Reverse removal procedure to install remaining components. Tighten all bolts to specification.

Torque specification for vibration damper bolt: 70 lbs
