The gear shift is the same as used on the

Model "B-C", except, the guide plate is

notched for the special low gear and the lever

is shaped differently and guide pins are used

to control lever.

Removal

Remove the seal boot from lever, and remove

the snap ring from transmission case. The

lever and retainer can be lifted frOin the case.

After the lever is out, the two lever guide pins

may be rernoved.

Remove the fo-ur screws attaching the shift

mechanism to-right side of transmission

case.

Note the position of the overshift washers.

To remove shift rails pull the retaining pins

from cover. If they cannot be pulled, drive

them on through and cut off excess as it

strikes cover.

Check shift rails for wear at detent notches.

Check forks for wear at gear contact section

and lever contact section.

The shift lever guide must be centered to line

up with shifter slots in both forks. The edges

of guide may not be worn excessively. 1£

either case exists the guide worn excessively

or guide not lining up it may be possible to

shift into two gears at once.

Assemblx

The third speed shift rail can ~e identified

by the three notches. The two front notches

are very close together. The notches are at

right angles to the retaining pin hole. The

third speed fork has the high shift lug. The

fork is installed with the fork towards front

-of case and shaft in R.H. position.

The low speed shift rail has three notches

in line with the retaining pin ho Ie.

The overshift washers should be repla_ced

just as they are removed. They are used

back of the third speed fork or in front of

the low speed fork, as required, to prevent

gears from rubbing when in the "in gear"

position.

The gear shift lever guide pins are cut diago-

nally and must be installed correctly. The

right hand pin is installed with the narrow

side of the head up. The left hand pin is

installed with the narrow side of head down.

1£the tractor is not equipped with the special

low gears, these pins may be turned over,

and will prevent the shift lever from enter-

ing the slot in shift lever guide.
