Changing Engine Oil and Filter

IMPORTANT: Change engine oil every 125 hours if diesel fuel has a sulfur content greater than 0.5 percent.

Operate engine to warm oil. Stop engine. Remove crankcase drain plug (A). Replace plug after oil drains out.

Remove filter (B). Remove old packing and clean filter mounting surface. Apply a thin film of oil to new packing and install new filter. Hand-tighten filter. Do not overtighten.

Refill crankcase with seasonal viscosity grade oil. (See Fuels, Lubricants, and Coolant Section.)

Start engine and check for leaks. Stop engine and recheck oil level.
