WHEEL 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.
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.

IMPORTANT -DRUM HEAD SEAL CARE
On each end of the mixing drum is a drum head containing self adjusting paddle shaft seals. These seals consist of packing rings, split glands and spring actuated adjusters. A properly maintained seal prevents material from working around the paddle shaft, causing excessive wear. The following is a suggested procedure of maintenance for protection of the paddle shaft and bearings:
A.Keep the drum head clean of plaster built up, so the spring adjusters will be free to work.
B.Replace with one new ring of packing and waterproof grease when split gland or pressure plate is about to bottom out against the end of the drum.
New Packing
When the old packing is to be completely replaced, coat shaft and packing generously with a good grade of waterproof grease and insert packing rings. Tighten the two spring adjuster nuts on each end until the spring is compressed to
Also, whenever the paddle shaft is removed, new waterproof grease should be packed around the ball bearings in the drum heads before reinstalling the shaft. Fill the cavity completely.
EM-120SM — MAINTENANCE
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.
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.
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..
PADDLE SHAFT BEARINGS
The paddle shafts in the Essick EM120PM 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:
■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.
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.
