are "in", that is, in the bottom of the driver slots, the

space between the top of the conical shaped race

bushing and hair pin clip should be .230" - .240". Use

.010" spacer washers to obtain required space. The

governor shaft is pressed into the gear and secured with

a screw that is partially in the shaft and partially in the

gear.

ASSEMBLY

1. When reassembling pistons and connecting

rods, use a good ring compressor and oil the bores

thoroughly. A hammer handle may be used to tap the

pistons out of the ring compressor into the cylinder bore.

2. Use care to prevent damage to cylinder bore

finish by the connecting rods when the connecting rods

are assembled over the crank pin.

Locate them

carefully to prevent damage to the bearing surface, and

crankshaft journals.

3. Always lubricate the bearings with clean engine

oil when assembling. Tighten the bearings to specified

torque. Use lockwires as required to prevent loosening

of nuts and screws.

4. Clean the cylinder head and block surfaces

thoroughly before installing the gasket.

Tighten all cylinder head capscrews evenly and in

SERVICE

The driver must always be tight to the shaft.

The races must be free on the shaft. In assembly of the

governor a space of .004" to .006" is provided between

the driver and the flat race. This is to assure freedom

for movement of the flat race. When servicing the

governor, make sure that both races revolve freely on

the

shaft.
