MS-40H HYDRAULIC MIXER MAINTENANCE  
WHEEL BEARINGS  
PADDLE SHAFT BEARINGS  
After every 3 months of operation, remove the hub dust cap and  
inspect the wheel bearings. Once a year, or when required,  
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 theSTOWMS-40H hydraulic 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.  
BEARING BRACKET  
Grease the bearing bracket every month.  
CLEANING  
SHAFT SEALS  
Always disconnect the spark plug wire before cleaning the inside  
of the drum.  
CAUTION:  
IMPORTANT -DRUM HEAD SEAL CARE  
Never pour or spray water over the gasoline engine or electric  
motor.  
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.  
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.
