2. Fill the wheel hub (Figure 39) with grease to the inside
diameter of the outer races and also fill the hub grease
cap. Reassemble the hub and mount the wheel. Then
tighten the adjusting nut, at the same time turn the
wheel in both directions, until there is a slight bind to
be sure all the bearing surfaces are in contact.
Then back-off the adjusting nut 1/6 to 1/4 turn or to the
nearest locking hole or sufficiently to allow the wheel
to rotate freely within limits of .001" to .010" end play.
Lock the nut at this position. Install the cotter pin and
dust cap, and tighten all hardware.
BOLT CONNECTOR
A 5/8 " x 4 1/4" bolt is used as a connector pin located
between the reduction gear assembly and the paddle shaft.
It is designed to protect the transmission in the event a rock
or other object should get caught between the paddle blade
and the drum, this pin may shear. It is recommended that an
extra bolt be kept on hand (use only a grade 2 or 5 size
bolt) so as to quickly make a replacement, if necessary.
CLUTCH ADJUSTMENT
If the rotating mixing paddles appear to be losing rotational
speed, it may be necessary to adjust the clutch. For
optimum performance Multiquip recommends 35-55 lbs.
applied pressure to the hand clutch lever. After the initial
operating hours (8) check the clutch for proper ensasment
pressure.
CAUTION
ALWAYS stop the engine, disconnect the spark
plug or electrical power cord before attempting this
procedure.
