Adjusting Shifting Linkage

HAND SHIFT. The hand shift normally requires adjustment only when transmission has been moved to adjust front drive chain, and then only the shifter rod needs adjustment to maintain correct hand shift lever position.

To adjust hand shift move the shifting lever to third position on four-speed transmissions and to second position on three-speed transmissions.

lever is in alignment with notch or mark in end of foot shift lever shaft, section 4B.

Adjust length of shifter rod so that the foot lever, when fully depressed, has about 1/16 in. clearance from foot lever cover mounting stud. Length of rod is adjusted by removing shifter rod end bolt, loosening shifter rod end lock nut, and turning rod end farther on or off rod. This rod adjustment is important, as any interference between foot lever and cover mounting stud will prevent full movement of foot lever and full engagement of shifting parts inside transmission.

Disconnect shifter rod from shifter lever; with slight backward and forward movement carefully "feel" the transmission lever into exact position where the shifter spring plunger (inside transmission) seats fully in its retaining notch.

By turning the clevis in or out, carefully refit the shifter rod to the shifting lever without disturbing the shifting lever's exact positioning.

FOOT SHIFT. The foot shift normally requires adjustment only when transmission has been moved to adjust front drive chain, and then only the shifter rod needs adjustment to maintain correct foot lever pedal position.

Check to make sure that clamping slot in shifter

ADJUSTING FOOT SHIFTER COVER. When it is impossible to shift foot shifting mechanism into all gears, adjust as follows:

Disassemble shifter cover parts 1 through 12 as described in "Disassembling Shifter Cover (Foot Shift)," see Fig. 4D-6. Time shifter notches as illustrated in Fig. 4D-8. Loosen screw (14, Fig. 4D-6) and rotate adapter plate (16) until timing notch (Fig. 4D-8) in adapter plate, located at bottom of shifter gear hole, lines up with notch between two shifter gear teeth. Make alignment exact, then tighten adapter plate bracket screw to lock in position. This adjustment can be made with shifter in any gear (not neutral).

Assemble shifter cover in reverse order of disassembly.
