Clutch Adjustment Mechanical 9 CF Mixer
If the rotating mixing paddles appear to be losing rotational speed,
it may be necessary to adjust the clutch. For optimum
performance Multiquip recommends 47.45-74.57 N-m (35-55 ft-
lbs). applied pressure to the hand clutch lever. After the first initial
operating hours (8) check the clutch for proper ensasment
pressure.
Clutch Adjustment Procedure
1. To gain access to the " Gear Reduction Compartment"
remove the four 14 mm (9/16-inch) hex head bolts that
secure the hood to the engine and remove engine hood.
2. Drain the clutch compartment oil (Figure 8) by removing
the magnetic 9 mm (3/8-inch) plug located at the bottom of
the Gear Reduction Assembly.
The Gear Reduction Compartment
consist of two compartments, a lower
and upper. The
lower
compartment
houses the clutch, the
uppe
r
compartment contains the actual gear
reduction. Remember each compartment requires a different
type of lubricating oil.
If the clutch cannot be adjusted, it may
be necessary to inspect or replace the
clutch.

the
adjustment lock
P/N EM 934040 and tighten lock
bolt.

clutch Inspection door
using the six 12 mm
(1/2-inch) cap screws and lock washers, and also check
that the gasket is not worn or broken.

on the lower clutch compartment. Refill the clutch
compartment with 2.12 liters (2-1/4 quarts) of SAE 30 motor
oil to the level of the plug. When done reinstall plug.
