1.Remove the 8x cover screws (102) and the speed-setting screw retaining
ring (132). Discard retaining ring.
2.Remove the governor cover (152) and cover gasket (151) from the assembly.
Once the cover is removed, ensure that gasket residue is completely
removed from the housing surface and no residue enters the inside of the
governor. Discard the cover gasket.
3.Remove the speed-setting screw (145) from the assembly by unthreading it
from the cylinder pivot pin (104). Discard the O-ring located in the top of the
speed-setting screw.

remove the loading spring (143) from inside the
speed-setting screw guide bore (142). Do NOT
remove bore (142), which is press-fitted in. Discard
the loading spring.
6.Remove spring clip (106) and replace with new (shorter) spring clip (Figure 3.
item 27). Be careful not to overstretch the spring clip; bend it just far enough
to fit in the holes by engaging first one side, and then the other
side. Make sure the tangs of the spring clip fully engage both the
feedback lever (105) and the speed-setting nut (115)
7.Remove the old governor nameplate and drive screws (the
nameplate may be on the side of the governor body as shown at

Mark the new nameplate with the new part number. Discard the
old nameplate.
9.Using new drive screws (Figure 3. item 21), attach the new nameplate
(Figure 3. item 20) to the side of the case (127) in the pre-existing holes. This
is the side that has the threaded breather hole (see photo).
10. Remove breather plug (101) and set aside for later installation.
11. Discard the old cover.
12. Orient mounting guide (22) with mounting tangs up.
13. Orient lever bracket (26) with mounting tangs down.

coils in line with the lever bracket and
mounting guide through-holes.

mounting guide holes, through the torsion
spring coils, and through the other set of
lever bracket and mounting guide holes.
