1. Disconnect rod assembly (2) from the lever on the governor.
2. Remove breather tube (3).
3. Remove drain hose (1) from the fuel system.
4. Remove plug (4). Tooling (A) can be used to turn the engine to put the No. 1 piston on top
center (TC) compression. If tooling (A) is used, remove the electric starting motor and install
tooling (A) in the flywheel housing. If tooling (A) is not used, the engine can be turned with the
bolt that holds the pulley for the vibration damper.
5. Put the No. 1 piston at top center (TC) compression as follows:
a) Turn the crankshaft clockwise (as seen from the front of the engine) until a 3/8"-16 NC bolt can
be installed in the hole from which plug (4) was removed. The bolt must go through the hole in the
flywheel housing and into the threaded hole in the flywheel.
NOTE: Never turn the crankshaft counterclockwise to install the bolt in the flywheel.
b) Disconnect the breather group from the valve cover. The rocker arms for the No. 1 piston can
be seen through the breather hole.
c) Check to see if both rocker arms can be moved backward and forward by hand through the
breather hole.
d) If both rocker arms can not be moved, the No. 1 piston is not at the top center (TC)
compression position. Remove the bolt from the flywheel. Turn the engine clockwise as seen from
the front of the engine one full turn 360° and install the bolt again.
