3-2. Detailed Lubrication Information.

a. Keep lubricants in closed containers and store

in a clean, dry place away from external heat. Allow

no dust, dirt or other foreign material to mix with the

lubricants.

6. Store lubrication equipment in a place where it

will be safe from damage. Clean the equipment

before and after use.

c. Keep all external parts not requiring lubrication

free of lubricants. Wipe all lubrication points free of

dirt and grease before lubricating, and clean all

lubrication points after you lubricate them to

prevent accumulation of dirt.

d. Check the crankcase oil level frequently when

operating under unusual conditions. You generally

have to change the oil more frequently than normal

under cold weather operation conditions because con-

tamination by fuel dilution and sludge formation will

increase under dusty and sandy conditions because

contamination by foreign matter increases.

3-3. Engine Lubrication.

Engine crankcase lubrication consists mainly of

changing the oil in the crankcase and servicing the

oil filter (LO 5-4320-273-12). Proceed as follows:

a. Run the engine long enough to heat it to

operating temperature. The warm oil will drain from

the internal engine parts much more rapidly than

cold oil and also will carry more dirt and sludge with

it as it drains.

6. Place a suitable container under the engine

drain port before you remove the oil pan drain plug
