unscheduled maintenance and increased downtime.
3-1. General.
LO 5-3895-372-12 tells you your responsibilities for lubrication of the mixer body It tells what lubricants to use and how
often to lubricate each point.
3-2. Special Instructions.
a. Auger Bearing (See fig. 3-1.) Flush and lubricate this bearing every four hours during operation, and also after
every cleanup. Lubricate it while the auger is turning. There are two fittings, one on the bearing and one over the seals.
Use waterproof lithium grease on this bearing and seals. Place the grease gun on each fitting and pump in enough grease
to displace all the previous grease. Wipe off the excess. This bearing cannot be greased too often or too much.
b. Chain Oiler (See fig. 3-2.) The chain oiler should dispense oil at the rate of five drops per minute. Check the flow
rate by observing the sight glass located under the unit as shown In figure 3-2. Adjustment is made during the production
of concrete (para 2-12b (2)).
c. Vibrator Air Lubricator (See fig. 3-3.) The vibrator air lubricator should dispense approximately one drop of oil
every third vibration. This rate may be checked by observing the sight glass on top of the unit. To adjust flow rate, turn th e
screw on top of the unit clockwise to slow down oil flow or counterclockwise to speed up oil flow. Check the sight gage on
the side of the reservoir to determine when the reservoir requires filling. Filling is only required when oil is not visible in the
sight gage. To fill the reservoir unscrew the knurled cap on top of the unit and pour in oil. Observe the sight gage to
determine when the reservoir is full Install and tighten the knurled cap finger tight.
