The Chrysler eight cylinder industrial engine has full pressure lubrication to all crankshaft, camshaft and connecting rod bearings. Oil capacity is six quarts. Level indicator is on the left side of the crankcase.

It is important to use proper viscosity oil. For summer use SAE 30. For winter temperatures ranging from 45° F. to 10° F. use 20W. For winter temperatures ranging from 10° F. above zero to 10° F. below zero use No. 10W. For more severe winter conditions, dilute No. 10W with one (1) pint of kerosene in six (6) quarts of lubricant. The oil pressure is from 30 to 45 lbs. at 1500 R. P. M.

The need for changing engine oil depends to a large degree upon local conditions. A comparison of the oil in the engine with fresh oil will generally serve as a guide. Lack of body and the presence of grit is an indication that fresh oil is needed. Oil should be drained when the engine is hot. Refill with six USS quarts of good oil.

The blower and chopper are mounted on a shaft which is suspended by a bearing on each end of the siren unit. At the horn end, the bearing is lubricated through the upper lubricating connection on the right hand side of the housing. The lower connection is to be used for draining the bearing. Refer to Fig. 4.

At the power end of the blower, the lubricant fitting is on the bearing cap. (Remove seat and guard assembly to lubricate.)

After six months of operation, drain the oil from the bearing on the horn end and wash out, using carbon tetrachloride. Refill with 3 ounces of medium roller bearing lubricant, U. S. Army specification No. 2-108, or equivalent.

Fill the one oil cup with light engine oil. Add 2 or 3 drops of light engine oil to wick beneath rotor. Caution-See that no lubricant or oil is on or near the breaker points.

Remove, thoroughly clean and re-oil air cleaner, at least twice a year.

OIL FILTER PIPE CAP AIR CLEANER

Remove, clean and re-oil air cleaner, at least twice a year.

GENERATOR AND STARTER MOTOR

Lubricate bearings, use only a few drops of light engine oil in each cup.

SIREN UNIT BASE

The base of the siren unit serves as a turntable and is geared to a reduction drive gear unit direct with power unit. There are two lubrication fittings that require a small amount of lubricant after six months of operation. Fig. 5.

The lower fitting on the base lubricates the ball bearings which operate in connection with the oilite rings.

The upper fitting lubricates the shaft which revolves in the base housing. (Use medium roller bearing lubricant, U. S. Army specification No. 2-108, or equivalent.)

This unit is mounted on a carrier support bracket at the front of the frame. There are two points to lubricate in the gear box assembly. The front compartment requires 1 pint of lubricant while the rear compartment requires 2 pints of lubricant. (Each compartment is to be lubricated separately.) Drain, flush and refill unit twice a year. For winter operation use 20W oil, for summer operation use SAE 30 oil. Lubricate reduction gear shaft front bearing with one ounce of medium roller bearing lubricant, U. S. Army specification No. 2-108, or equivalent.

The transmission is of a step-up constant mesh design. The oil capacity is 1'/s pints. Drain, flush and refill the unit twice a year. For winter operation use 20W, for summer operation use SAE 30.

WATER PUMP

Lubricate the engine water pump with water pump lubricant only. (One fitting only.)

UNIVERSAL JOINT

The universal joint is of the needle bearing type. Once a year, disassemble, wash bearings, and repack with fresh universal joint lubricant.
