Installing Shaft Mount Rocker Systems on Gen III Engines

8) Once the valve lash adjuster has been seated,
loosen the adjuster nut and set the adjuster for valve lash. Retighten
the adjuster nut to 35 ft.lbs. Do not run the rocker arm with the
adjuster bottomed out, as doing so will result in damage to the rocker
arm and other engine components.

9) Place the tip of an oil can against the oiling hole
in the adjuster, and pump the handle until oil comes out of the oil
passage behind the rocker arm roller tip.

Post Installation Maintenance

• The synchronized oil system must be inspected periodically for obstructions that may prevent proper rocker arm oiling.

• After the valve has been adjusted to camshaft specifications, verify
that the 12 pt adjuster nut has been torqued to 35 ft.lbs. Failure to
do may result in severe engine damage if the adjuster nut should come
loose while the engine is running.

Note: Do not re-tap the 7/16” adjuster hole with any type of tap other
than a 7/16?-20 roll forming tap (Union-Butterfield p/n 1310209 or
similar) as doing so will damage the rocker arm beyond repair.

Factors of Crankshaft Selection

From the high-performance powerplants propelling Top Fuel dragsters to the subdued engines found in family sedans and grocery getters, each crank must be tailored to, and appropriate for, its specific application.

We know a crankshaft plays a critical role in an engine’s performance, converting reciprocating motion into rotary motion while serving as the backbone of the entire system. It must be strong enough to withstand the continuous pounding of rods and pistons, yet possess enough elasticity to absorb vibrations and flex, albeit slightly, when needed.
