IMPORTANT: Engine mounts must be adjusted, as explained in Steps 3. and 4., to
center mount adjustment and establish a uniform height on all mounts.
3. Check all 4 engine mounts (2 front, 2 rear) to ensure that distance from bottom of mount
to bottom of trunnion is as shown. If not, loosen mount locking nut and turn adjusting nut
in direction required to obtain proper dimension, then retighten locking nut. Be sure to
leave mount positioned so that slot is forward.
4. Loosen clamping bolts and nuts on all 4 engine mount brackets to ensure the following:
• Large diameter of mount trunnion extended.
• Mount base slotted mounting hole forward, if so designed.
• Each mount base is downward. Tighten clamping bolts and nuts slightly to prevent mov-
ing in or out. Mounts must be free to pivot when installing engine.
