ENGINE DISASSEMBLY
NOTE:
Fully tighten the tool holding bolts, but
make sure the tool body is parallel with the
case. If necessary, one screw may be
backed out slightly to level tool body.
●
As pressure is applied, alternately tap on
the front engine mounting boss, transmis-
sion shafts and balancer shaft.
CAUTION:
●
Use soft hammer to tap on the case half.
●
Tap only on reinforced portions of case.
●
Do not tap on gasket mating surface.
●
Work slowly and carefully.
●
Make sure the case halves separate
evenly. If one end “hangs up”, take pres-
sure off the push screw, realign, and start
over. If the cases do not separate, check
for a remaining case screw or fitting. Do
not force.
