REPAIR INSTRUCTIONS, PART 1

Dowel Pins — A combination of round- and
blade-style locating dowel pins are used to install
the front cover and flywheel housing. A
blade-style pin is used for the flywheel. When
installing the blade-style pins, make sure the
blade is properly positioned:
앫 Vertically (pointing up and down) — for the
flywheel housing
앫 Parallel to crankshaft center line — for the
flywheel
앫 Angled (perpendicular to the pin hole
centerline of the dowel pin holes) — for the
front cover
INSPECTION
Inspect the flywheel housing machined surfaces,
capscrews, holes and dowel locations for cracks
or wear. Replace the housing if cracks are
evident.
Before installing the flywheel housing, examine
the crankshaft flange for any cracks, surface
damage or presence of foreign particles. This
type of damage could ruin the sealing capabilities
of the new seal and lead to oil leakage.
INSTALLATION
1. Remove the rear crankshaft oil seal from the
flywheel housing by drilling two 3 mm holes,
180 degrees apart, into the outer edge of the
seal. Remove the seal with a slide hammer
fitted with a No. 10 sheet metal screw.
Thread it into each of the holes alternately
and work the seal free.
2. Using standard shop cleaning procedures
for aluminum, clean the seal mounting
surface.
3. Insert the two dowel pins in the cylinder
block if they were removed. Refer to
Figure 337.
The flywheel housing dowels maintain the
alignment of the flywheel housing on the engine.
This is necessary to center the transmission with
respect to the engine flywheel and crankshaft.

4. Apply an even coat of RTV silicone
(approximately a 1/16-inch [2 mm] bead) to
the flywheel housing mounting surface of the
cylinder block. Refer to Figure 338.
