Assembly of Case and Crankshaft Assembly
(1) With crankcase halves lying on bench
with interior sides up, ensure that center
and rear main bearings (5, Figure 72-
00-09.2) are installed and lubricated
with pre-lube.
(2) Lubricate tappet bore holes and tappet
bodies (20) (shank) and install bodies in
case.
(3) Apply cam pre-lube liberally to tappet
(20) faces and camshaft lobes. (5,
Figure 72-00-09.8). A moly-graphite
grease is recommended.
(4) Place camshaft (5) on bench beside
case halves.
(5) Clean mating surfaces of both case
halves including nose seal area with fast
dry solvent.
(6) Clean nose seal OD with fast dry
solvent.
(7) Place front main (10, Figure 72-00-09.2)
bearing temporarily in place in the left
crankcase half making sure the bearing
is properly seated on the 2 locator
dowels.
NOTE:
The front main bearing (10), unlike the
center and rear main bearings, splits
on the horizontal centerline of the
engine.
(8) Use a felt marker to trace on the front
bearings halves at the intersection
between the crankcase parting flanges
and the bearing. Make a vertical
reference mark on both the bearing half
and each case half at a convenient point
along the line of intersection. This
locates the bearing both radially and
axially. Make two parallel marks across
both bearing shells at their intersection
for alignment reference. Refer to Figure
72-00-09.9.
WARNING
: LUBRICANTS ARE TOXIC AND
FLAMMABLE. DO NOT BREATHE VAPORS.
BEFORE YOU USE, READ THE MATERIAL
SAFETY DATA SHEET (MSDS) FROM THE
MANUFACTURER OR SUPPLIER. USE IN A
WELL-VENTILATED AREA FREE FROM
SPARKS. WEAR PROTECTIVE GEAR. IN
CASE OF EYE CONTACT, FLUSH WITH
WATER FOR 15 MINUTES AND SEEK
MEDICAL ATTENTION. IN CASE OF SKIN
CONTACT, WASH WITH SOAP AND WATER.
(9) Remove front main bearings. Lubricate
bearing surfaces liberally with pre-lube
oil and fit to crankshaft aligning the two
parallel marks. Refer to Figure 72-00-
09.10.
(10) Install two 3/8 in. bolts with their
corresponding flat washers through the
right case half and install 2 O-rings (10,
Figure 72-00-09.11).
(11) Install 2 O-rings (75) on rear through
studs of right case half.
(12) Lubricate crankshaft main bearing
journals and cam bores with pre-lube oil.
(13) Lay out crankcase assembly hardware
per Figure 72-00-09.11 and 72-00-09.12
together with appropriate hand tools.

PERFORM IN-PROCESS QUALITY
INSPECTION #1. REFER TO APPENDIX A.
(14) Assure that case mating surfaces are
clean and dry.
WARNING
: ADHESIVE SEALANT IS TOXIC
AND FLAMMABLE. DO NOT BREATHE
VAPORS. AVOID EYE AND SKIN CONTACT.
USE PROTECTIVE GEAR. IN CASE OF EYE
CONTACT, FLUSH WITH WATER FOR 15
MINUTES AND SEEK MEDICAL ATTENTION.
IN CASE OF SKIN CONTACT, WASH WITH
SOAP AND WATER.
(15) Apply an even, thin coat of approved
sealant to the backbone and breastbone
surfaces of the left case half only and to
the front nose seal bore (both case
halves) as well as the nose seal OD.
(16) When using RTV 102 the coating must
not be too thick. A thin translucent
coating is sufficient. Wipe off any
excess on the inside and outside edges.
Refer to Figure 72-00-09.13. Because
this sealant will dry quickly when applied
this thinly, it is important to proceed
quickly until case halves are together
and snug. A helper is required during
this assembly process.
