Hudson 1955 Rambler, Technical & Service Manual

The slinger is held in place by the crankshaft
sprocket and vibration damper.
CAMSHAFT AND BEARINGS
The camshaft is supported by four steel
shelled, babbitt lined bearings which have
been pressed into the block and line reamed.
The camshaft bearings are step bored being
larger at the front bearing than at the rear
to permit easy removal and installation of the
camshaft. All camshaft bearings are lubri-
cated under pressure through drilled passages
in the cylinder block.
To simplify camshaft removal on the "Hornet"
and "Wasp" Series, remove the radiator core
and grille assemblies and intake exhaust
manifold. Then raise the front of the engine
slightly.
On cars equipped with air conditioning and all
"Rambler" Series, the engine should be
removed for camshaft removal.
The engines should also be removed from the
car if camshaft bearing replacement and/or
line reaming is contemplated.
