(q) Apply a thin coat of sealant (item 21, Appendix C) to the outside diameter of new governor housing cup

plugs (22). Start the plugs, open end out, straight into the shaft openings; then press the plugs in flush with

the outside face of the housing boss.

(r) Lubricate the terminal lever to power piston pin (23) with engine oil (item 8, Appendix C). Raise the edge

of the terminal lever and insert the pin in the hole in the power piston; then lower the terminal lever down

on the pin.

(s) Place the non-slotted end of the speed adjusting floating lever (12) in the slot on the speed adjusting lever

shaft (6) so that the pin holes are in alignment. Insert the long end of the speed adjusting lever-to-floating

lever wire pin (16) through the pin hole in the speed adjusting lever and floating lever.

(t) Place the speed adjusting floating lever in the slot of the speed adjusting lever fork (7) with the pin holes in

alignment; then insert the short end of the wire pin (18) through the hole in the spring fork and floating

lever.

(u) Push the wire pin in against the speed adjusting lever and spring fork and bend the protruding end of the

pin over toward the slotted end of the floating lever.

(v) Press the lower end of the spring fork (13) into the small end of the speeder spring (14); then insert the

opposite end of the spring in the spring seat of the pilot valve plunger (15).

(w) Lubricate the pilot valve plunger thrust bearing (17) with engine oil (item 8, Appendix C) and place it over

the end of the pilot valve plunger with the smallest, outside diameter, bearing race next to the spring seat.

(x) Lubricate the pilot valve plunger with engine oil (item 8, Appendix C). Hold the thrust bearing against the

spring seat and insert the assembly in the governor housing with the speed adjusting lever facing the two

bushings inside the housing. Start the pilot valve plunger straight into the bore of the governor weight and

push the assembly in until the speed adjusting lever is in position between the two bushings and the thrust

bearing is resting on the lip of the flyweights.

(y) Lubricate the governor speed adjusting shaft (6) with engine oil (item 8, Appendix C). Rotate the shaft so

the machined slot in the outside diameter of the shaft is in the same position it was in at the time of

removal. Then, insert the shaft in the shaft bushing in the housing, from the oil inlet plug side, with the roll

pin hole in the shaft and lever in alignment.
