Replace engine oil filer (C) and packing. Remove old packing and clean filter mounting pad. Oil new packing and install new element. Hand tighten only. Crankcase capacity with filter is 18 qt. (17.0 L).

Refill crankcase with seasonal viscosity grade oil recommended in the Fuels and Lubricants section.

Start engine and check for leaks.

Stop engine. Recheck oil level.

2. CHECK MFWD DRIVE AXLE HOUSING AND WHEEL HUB OIL LEVEL.
