STEP 1.
Clean the old adhesive from connecting rod bearing (mounted
on the eccentric).
Apply Loctite® #680 (supplied) to the bearing bore of
the new connecting rod. (See Fig. #2). Apply Loctite® #242 (supplied) to
the threads of the clamping screw, and turn the screw a few turns into the
new rod. Do not tighten. Drop the new rod and sleeve assembly through
the top of the compressor housing with the head of the rod clamping screw
to the right (as viewed through the open end of the compressor housing).
Slide the eccentric and bearing assembly onto the shaft and into the bear-
ing bore of the connecting rod. (See Fig. #4)
CHECK OPERATION
STEP 5.
Hold the sleeve down
against the housing with one hand,
and slowly rotate the eccentric with
the other hand. As the piston travels
up and down it will also rock from side
to side. This is a feature of the WOB-L
Piston.
If it rocks from front to rear,
the connecting rod is misaligned
on the eccentric.
If front to rear rock-
ing is detected, loosen the connecting
rod clamping screw and repeat Steps
6, 7, and 8. If the connecting rod can-
not be properly aligned, contact the
nearest service center.

down
STEP 2.
Align the front face of the con-
necting rod with the front face of the bear-
ing. This will result in a clearance of about
.032 inch between the rod and the eccen-
tric (See Fig. #6). Tighten the connecting
rod screw to 15 in. - lbs. torque. DO NOT
OVERTIGHTEN, or bearing damage/con-
necting rod breakage may result.
STEP 3
Center rod and sleeve in pocket in the top of the unit.
STEP 4.
Slide the sleeve down until it contacts the housing. The locator
ribs should bear against the inside surface of the sleeve.
