GOVERNOR GEAR AND SHAFT SERVICE

After the cylinder cover is removed from the engine, the
governor spool, gear, and governor shaft can be
removed. A retaining ring must be removed to allow the
gear to be removed from the shaft. (Illust. 4-6)

GOVERNOR SHAFT REPLACEMENT

1. Remove the spool, retaining ring, gear assembly and
washer(s).
2. Clamp the shaft in a vise and pound gently on the
flange with a wooden or plastic mallet to remove the
shaft.
NOTE: DO NOT TWIST THE SHAFT WHEN
REMOVING. THE SHAFT BOSS MAY BECOME
ENLARGED AND THE PRESS FIT WILL NOT
SECURE THE NEW GOVERNOR SHAFT.
3. Start the new shaft into the flange boss by tapping
with a soft faced hammer.
4. Apply a small amount of red loctite 271 to the lower
governor shaft and using a press or vise push the
governor shaft into the flange leaving an exposed
length of 1.196" (3.969 mm).

SPEED CONTROLS AND LINKAGE

The TVT series engine offers the adaptability of throttle
cable connection from either side of the engine. Either
cable position must pull against the governor spring force,
to increase the engines speed. NOTE: Both the upper
and lower governor spring connections, they must be
installed correctly to prevent improper operation.

NOTE: Whenever the carburetor or the governor linkage
is removed or replaced, the engines governed R.P.M.'s
must be checked. Use microfiche card #30 or the
computer parts look-up systems to locate the correct
R.P.M. settings for the engine model and specification
you are repairing.
