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.
