Flywheel; Gear Cover - Onan T260G Service Manual

FLYWHEEL GEAR COVER
Removing the flywheel is a relatively simple process,
but the following procedure must be followed to avoid
damage to the gear case and possible injury to the
operator.
1.
Turn the flywheel mounting screw outward about
two turns.
WARNING
Do not remove the screw com-
pletely since it acts as a re-
strainer when the flywheel snaps loose. If the
flywheel is not held by the screw, the spring
action in the wheel will cause it to fly off with great
force which can cause lnjury to the operator.
After removing the mounting screws, tap the gear cover
gently with a soft faced hammer to loosen it.
When installing the gear cover, make sure that the pin in
the gear cover engages the nylon lined (smooth) hole in
the governor cup (Figure 9). Turn the governor cup so
that the nylon lined hole is at the three o'clock position.
Use a small amount of grease to assist in holding
governor cup in position. The smooth side of the
governor yoke must ride against the governor cup. Turn
the governor arm and shaft clockwise as far as possible
!
and hold in this position until the gear cover is installed
flush against the crankcase. Be careful not to damage
the gear cover oil seal.
2. Install a puller bar on the flywheel (Figure 8).

4. Unscrew the puller from the flywheel, remove the
flywheel mounting screw and washer and pull the

flywheel.
