disassemble the wheel hubs remove the old grease and repack  
the bearings forcing grease between rollers, cone and cage  
with a good grade of high speed wheel bearing grease (never  
use grease heavier than 265 A.S.T.M. penetration (No. 2.) Fill  
the wheel hub with grease to the inside diameter of the outer  
races and also fill the hub grease cap.  
The paddle shafts in the STOW MS-40M mixers rotate in sealed  
ball bearings, which require no additional lubrication as they  
are packed and sealed at the factory.  
There is, on each end of the mixing drum, an zerk grease fitting.  
Oil these fittings two or three times each week as they lubricate  
the dumping mechanism of the mixing drum.  
CAUTION:  
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.  
I
Failure to lubricate the zerk grease fittings  
two or three times a week will cause the  
dumping mechanism to stiffen, making the  
mixer hard to dump.  
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 so as to quickly make a replacement, if necessary.  
SHAFT SEALS  
CAUTION:  
IMPORTANT -DRUM HEAD SEAL CARE  
Grease seals every 40 hours of operation using  
any grade #1 lithium base grease. Apply  
grease until visible inside of mixing tub (over  
grease). this will purge seal system of  
contamination.  
NOTE  
This connector pin bolt is special. When replacing this  
bolt consult the parts section of this manual for the  
correct part number.  
CLUTCH REDUCTION ASSEMBLY LUBRICATION  
The clutch reduction assembly has two separate compartments.  
Each of which must be filled with its proper lubricant and checked  
at regular intervals.  
BEARING BRACKET  
Grease the bearing bracket every month.  
CLEANING  
The clutch compartment should be filled with a good grade of  
number 30 SAE engine oil which can be poured through the  
filler hole located just above the clutch inspection door on the  
opposite side of the transmission. Fill the clutch compartment  
with 30 SAE engine oil until it overflows the oil level plug located  
on the shifter side of the clutch compartment . Check this oil level  
every two or three months and add oil as required. Drain and  
refill once a year.  
Always disconnect the spark plug wire before cleaning the inside  
of the drum.  
Never pour or spray water over the gasoline engine or electric  
motor.  
For consistent performance, long life and high quality mixing,  
thoroughly clean the mixer inside and out at the end of each  
days operation. To prevent lumps of dried mortar from forming  
and contamination of future batches, do not allow a buildup of  
materials to form on the blades or anywhere inside the drum.  
The reduction gear, upper compartment should be filled with  
number 90 SAE oil, as used in automobile transmissions. The  
filler plug is at the top of the reduction gear case and the oil level  
plug is on the same side of the case as the clutch lever. Fill the  
reduction gear compartment with 90 SAE transmission oil until it  
overflows the oil level plug. Check this oil level every two or  
three months and add oil as required. Drain and refill once a  
year.

MS-40M MAINTENANCE  
Clutch Adjustment Mechanical 12 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 35-55 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
