Shifting Mechanisms
SUBJECT: Breakage of shift link lever and screw assembly;
50 H.P. models V4-10 thru V4SL-11B; &
75 H.P. models V4S-12 thru V4AL-13C.
In the course of servicing the subject engines it
is of course frequently necessary to remove the
shift link lever and screw assembly illustrated in
figure 1. From all indications, personnel doing
field service repairs are not correctly removing
this assembly. Examination reveals breakage is not
occurring during engine operation, but is instead
the result of attempting to pry the shift link
lever assembly from the shift lever shaft.
To correctly disassemble the shift link lever from
the shaft, the screw must first be completely
removed...not merely loosened a few turns. Removal
of the screw is necessary because the shift lever
shaft is slotted on its top side to allow the
screw to pass through which thus provides a double
locking arrangement. Consequently, if the screw
is not removed, attempts to pry the shift link
lever off the shaft will result in its breakage.
The correct procedure for removing the shift link lever and screw assembly is as follows:
1. Locate shift lever in neutral position.
2. Completely remove the screw from the shift link lever.
3. Pull the shift lever straight out.
