Read articles →An owner walking through the full 50-hour service on his RK25 (TYM T25) across multiple filming sessions, with a timestamped checklist built into the video for easy navigation. Covers front axle oil drain and fill (with wheel removal shown), engine oil change including a real struggle finding the right filter wrench, transmission and hydraulic fluid, radiator dust screen, greasing Zerk fittings, and bolt-tightness check. Best for first-time RK25 owners prepping for their own 50-hour service.
An owner-operator sharing candid, learn-as-I-go impressions from his own barn, including honest on-camera mistakes.
The engine oil fill calls for two point seven liters. The owner used Rotella 10W30 from a three point seven liter jug, filling about half before checking the dipstick.
A standard filter wrench did not fit due to tight quarters. The owner eventually used smaller giant channel locks that closed tighter to get the filter off.
It is located down by the PTO shaft. The owner used an iPhone as a light to check the level, noting it was hard to see even with glasses on.
The recommendation is every ten hours of use on implements, backhoes, and loaders, checking or re-greasing the Zerk fittings at that interval.
