A. Drive pins
CAUTION : Make sure drive pins of bear-
ings are on exhaust side of crankcase for
proper seating in recesses.
3,7, Seal
At seal assembly, apply a light coat of lithium
grease on seal lips.
For bearing lubrication purpose, a gap of 1.0 mm
(.040 in) must be maintained between seals and
bearings.
When installing plain oil seals (seal without locat-
ing ring or without spacing legs), ensure to main-
tain a 1.0 mm (.040 in) gap. For seals with spacing
legs, install them against the bearing.

1,8, Upper Crankcase and Lower
Crankcase
Crankcase halves are factory matched and there-
fore, are not interchangeable or available as single
halves.
Prior to joining of crankcase halves spray some
new injection oil (or equivalent) on all moving
parts of the crankshaft.
Spray Activator (P / N 413 7081 00) on one of the
mating surface to ensure paste gasket will fully
cured. It increases cure speed and gap filling ca-
pability.
Then apply paste gasket Loctite 515 (P / N 413
7027 00) on the other crankcase mating surface.
CA UTION : Before joinin g crankcase
halves be sure that crankshaft rotary valve
gear is well engaged with rotary valve shaft
gear.
Position the crankcase halves together and tight-
en screws by hand then install and tighten arma-
ture plate on magneto side to correctly align
crankcase halves. Apply Loctite 242 on screw
threads and under head. Torque screws as speci-
fied following illustrated sequence.
1.
Follow sequence shown 1 to 14 – 25 N•m (18 lbf•ft)
15 and 16 – 10 N•m (90 lbf•
in
)
NOTE :
Torque the 2 smaller screws (15 and
16) on magneto side to 10 N•m (90 lbf•
in
).
