ROCKER ARM
DESCRIPTION
The unique intake and exhaust rocker arms have their own rocker shafts and are lubricated by passages intersect-
ing the cylinder block main oil rifle. Crossheads are used, which allow each rocker arm to operate two valves.
The solid push rods are hardened at the rocker arm and tappet contact areas for superior strength and durability.

can be installed in their original position.
CAUTION: When removing the rocker arms, the
sockets may come loose and fall into the engine.
Make sure they stay with the arm upon
removal/installation.
6. Connect battery negative cables.

age the gear housing surface. Remove any old
sealer from the oil seal bore. Thoroughly clean the
front seal area of the crankshaft. Do not sand this
surface. The seal lip and the sealing surface on the
crankshaft must be free from all oil residue to pre-
vent seal leaks.

replace if necessary. Carefully straighten any bends
or imperfections in the gear cover with a ball-peen
hammer on a flat surface. Inspect the crankshaft
front journal for any grooves or nicks that would
affect the integrity of the new seal.

mer (4).
INSTALLATION
CAUTION: The seal lip and the sealing surface on the crankshaft must be freefrom all oil residue to prevent
seal leaks. The crankshaft and seal surfaces must be completely dry when the seal is installed. Use a soap
and water solution on outside diameter of seal to ease assembly.
1. Clean the crankshaft journal with a suitable solvent and dry with a cleanshop towel or compressed air. Wipe the
inside bore of the crankshaft seal retainer with a clean shop towel.
2. Inspect the crankshaft journal forgouges, nicks, or other imperfections. If the seal groove in the crankshaft is
excessively deep, install the new seal 1/8” deeper into the retainer bore,or obtain a crankshaft wear sleeve that
is available in the aftermarket.
