3. Inspect the connecting-rod bearings by rotating
them. The bearings must rotate freely and must not
bind or feel rough. If a connecting-rod bearing
must be replaced, the connecting rod and crank pin
must also be replaced.

4. Inspect the oil-injection pump drive gear for any
signs of worn or chipped teeth. If either condition
exists, replace the gear.
NOTE: Lubricate bearings thoroughly prior to
assembly.
Removing/Installing Outer Crankshaft
Bearings
NOTE: The end bearings are not pressed onto
the crankshaft. The bearings can be removed sim-
ply by sliding them off the crankshaft.
CM161
Inspect the crankshaft bearing area for wear. If any
wear is noted on either end, replace the crankshaft end.
NOTE: Install the bearings by sliding each bear-
ing onto the crankshaft making sure the dowel-pin
hole in the outer race is properly positioned and
will align with its hole and pin in the crankcase.

Measuring Critical Components
Cylinder Head Volume (Squish-Gap
Method)
To check the squish gap, a micrometer and two heavy
pieces of solder will be needed.
1. Remove the spark plugs from the engine.
2. Simultaneously insert two pieces of solder down
through the spark plug hole and push them up
against the inner cylinder bore towards the MAG-
side and PTO-side of the cylinder.
3. Pull the recoil rope and crank the engine over sev-
eral times while the solder is being held firmly in
place.
4. Remove both pieces of solder from the cylinder.
Using the micrometer, measure the very end of the
squeezed solder piece. Record the reading.
NOTE: If the solder hasn’t been squeezed by the
piston, a larger piece of solder must be used.
Repeat procedure.
5. Using the opposite end of the solder pieces, insert
them down through the spark plug hole towards the
PTO-side and MAG-side of the cylinder. Push on
the solder until they contact the inner cylinder bore.
6. Pull the recoil rope and crank the engine over sev-
eral times. Remove both pieces of solder from the
cylinder and measure the opposite squeezed ends
with a micrometer. Record reading.
NOTE: Measure from PTO to MAG-side of the pis-
ton to accurately measure the squish gap. Never
measure across piston, exhaust to carburetor
side, as the piston will rock and the reading won’t
be accurate.
Readings may vary from side to side.
NOTE: Make sure the smaller reading is 1.5 mm
(0.059 in.) or less.
