26. Turn the crankcase over and install the left
crankcase bolts.
CAUTION
Rotate the crankshaft frequently dur
ing the tightening process. If there is
any binding, stop and correct the
cause before proceeding.
27. Evenly tighten the left crankcase bolts in
1/4-turn increments in the sequence shown in Fig-
ure 76. Once all the bolts are snug, torque them in
sequence to the following specifications:
a. Bolts Nos. 4-6 (10 mm): 39 N•m (28 ft.-lb.).
b. bolts Nos. 1-3 and 7-19 (6 mm): 10 N•m (89
in.-lb.).
28. Turn the crankcase over and torque the right
crankcase bolts in sequence (Figure 76).
29. Check the operation of the crankshaft and
transmission. Rotate the universal joint yoke and
shift the transmission through the gears. If neces-
sary, disassemble the crankcase and correct any
problem now.
30. Install all external assemblies that were re-

Crankcase Inspection

1. Using a scraper, remove all sealer residue from
all crankcase mating surfaces.
WARNING
When drying the crankcase bearings
in Step 2, do not allow the inner bear
ing race to spin. The bearings lack lu
brication and damage will occur.
When drying the bearings with com
pressed air, hold both races with your
hand so the bearing will not rotate.
The air jet will force the bearings to
turn at speeds that exceed their design
limit. The likelihood of a bearing dis
integrating and causing serious in
jury and damage is very great.
2. Clean both crankcase halves and all crankcase
bearings with cleaning solvent. Thoroughly dry
them with compressed air.
3. Clean all crankcase oil passages with com-
pressed air.
4. Lightly oil the crankcase bearings with engine
oil before checking the bearings in Step 5.

NOTE
When replacing a bearing, also re
place its mate in the opposite case
half. Crankcase bearings should be
replaced as a set.
5. Rotate the bearings slowly by hand, and check
them for roughness, pitting, galling and play. Re-
place any bearing that turns roughly or shows ex-
cessive play.
