Disassembly and Assembly
Install washer (6) with the large diameter toward
the front of the engine. Install bolt (7) and tighten it to a
torque of 6.8 N m (60 Ib.in.).
Install tooling (B) as shown in the flywheel
NOTE: Make sure bolt (7) does not loosen as the
flywheel is turned.
Use tooling (B), and turn the flywheel in the
direction of engine rotation until bolt (8) [3/8"-16 NC x 4
in. (102 mm) long] can be installed In the flywheel.
NOTE: Do not turn the crankshaft counterclockwise to
get bolt hole alignment.
If you go past the bolt hole in the flywheel, turn
the crankshaft counterclockwise opposite the direction of
engine rotation (as seen from the front of the engine)
approximately 30 degrees. This procedure will permit
the (backlash) gear clearance to be removed from the
timing gears when the crankshaft is turned in the
direction of engine rotation (clockwise).
Loosen the clamp and bolt that hold the breather
cap to the valve cover. Remove the breather cap and O-
ring seal from the valve cover.
NOTE: The No. 1 piston is at top center on the
compression stroke when the bolt can be put in the
flywheel through the hole in the flywheel housing, and
both rocker arms for the No. 1 piston can be moved by
hand (have clearance with the valve stem).
When both rocker arms are loose, tighten bolt
(7) to a torque of 270 ± 25 N m (200 18 Ib.ft.).
Remove tooling (A) and (B) and bolt (8) from the
Put the O-ring seal and breather cap (11) in
position on the valve cover and the hose. Install hose
clamp (10) and bolt (9). Tighten bolt (9) to a torque of 14
3 N m (10 2 lb.ft.).
If studs (12) were removed, put 5P3413 Pipe
Sealant with Teflon on them, and install them in the
timing gear cover. Put the gasket and cover (13) in
position, and install the washers and nuts that hold them.
Tighten the nuts to a torque of 27 7 N m (20 5
