Change Engine Oil
Drain oil with engine shut off, but with engine oil still warm.
1.
Remove drain screw (A).
2.
While crankcase is draining, replace filter element.
3.
Reinstall drain screw and tighten to 50 N·m (37 lb-ft). Use new seal ring.
4.
Fill crankcase with fresh oil of proper viscosity at filler neck cap (B). See "Fuel, Lubricants, and Coolant" Section.
| Crankcase Capacity, with Filter |
| |
| 72-73-74-7520 ... 19.5 L (21.0 qt) |
| |
5.
Operate engine for a short time and check for leaks at filter base and drain screw.
6.
Stop the engine. Wait 15 minutes then recheck oil level. Level anywhere inside cross-hatch area is considered FULL. If necessary add oil, but avoid overfilling.
IMPORTANT:
Change oil whenever a seasonal change in temperature makes oil of a different viscosity necessary.
NOTE:
Change engine oil and filter after first 100 hours of operation.
