It walks through hood access, two drain plugs (noting the backhoe bracket complication), filter removal, oil fill, and a post-start level recheck, with specific callouts like the 17mm socket, part number, and Shell Rotella 10W-30 diesel spec. Most useful for first-time RK25 owners doing this job solo.
An owner-operator channel documenting maintenance on their own RK25, with no apparent commercial affiliation to Rural King or the manufacturer.
It has two oil drain plugs for the engine oil pan, one on each side, both draining straight down into a drain pan.
A 17-millimeter socket or wrench is used to loosen and retighten both oil drain plugs.
The video uses Shell Rotella SAE 10-30 heavy-duty diesel engine oil, and the engine calls for 2.9 quarts.
If you have a backhoe, a cross beam bracket with three bolts can be loosened and rotated down to avoid oil spilling on it during the drain.
