bushing if damaged. Replace either shaft bearing if
rough or noisy. Replace the bearing snap rings if dis­
torted or cracked.
Check the machined surfaces on the output shaft.
These surfaces should clean and smooth. Very minor
nicks or scratches can be smoothed with crocus cloth.
Replace the shaft if worn, scored or damaged in any
way.
Inspect the output shaft bushings (Fig. 36). The
small bushing is the intermediate shaft pilot bush­
ing. The large bushing is the overrunning clutch hub
bushing. Replace either bushing if scored, pitted,
cracked, or worn.
The bushings can be removed with blind hole
puller tools such as Snap-On set CG40CB for small
bushings and set CG46 for large bushings. New
bushings can be installed with tools from an all pur­
pose installer kit such as the Snap-On A257 bushing
driver set.
GOVERNOR OVERHAUL
42RH/46RH models have an aluminum governor
weight assembly. 47RH models have a brass/bronze
alloy weight assembly. A 3-stage assembly is used in
all except the diesel version of the 47RH.
The 3-stage governor weight assembly consists of
an outer weight, a smaller weight spring, an inner
weight, and a new intermediate weight. The sleeve-

like intermediate weight fits inside the outer weight,
and the inner weight now fits inside the new inter­
mediate weight.
The governor body is different. A retainer washer
was added to help secure the outer weight in the
bore; the washer backs up the original snap ring
which is still used. The new governor body has a
slightly longer governor weight bore.
