GENERAL INFORMATION:
The output shaft included in this kit must be installed into a custom built, fully manual C-4 transmission. The length
of this kit does not leave any space for the governor assembly; therefore, it must be used with a manual valve body.
Additionally, the governor housing needs a lathe modification and a mill/drill press modification.
INSTRUCTIONS:
1. Have a transmission shop build the fully manual C-4 with the 52-2905 output shaft.
2. Give the governor casting to a qualified machinist to turn the part down to the desired thickness of 0.530" +/- 0.005".
This can be seen below in the picture. The second modification is to countersink the four 5/16" bolt holes until the
included 5/16"-18 flat head cap screws sit flush with the surface.
GOVERNOR HOUSING:
To the left is the unmodi-
fied housing. To the right
is the housing after it has
been machined down to
the correct thickness of
0.530" +/- 0.005".
