Installation
CAUTION
Do not mix push tubes during installation. The injector tube is
the longest and installs between the intake and exhaust push
tubes. Intake and exhaust push tubes are identical. Mixing push
tubes may cause damage to equipment.
The fit of push tube ball ends into cam follower sockets is
critical. Perform several visual checks during installation to
ensure push tubes remain properly seated.
NOTE
On late model engines, many lockwashers have been replaced by
screw-assembled washers.
All rocker lever housings are installed essentially the same. This
procedure covers one rocker lever housing.
