Part of the Yanmar Parts Manuals.
All 93 pages of the Yanmar S165R-1 / 4TNV98C-NMS2 Parts Catalog (OEM #0CK50-M00570EN) map every replaceable component on your skid-steer loader, from chassis frame hardware to the full hydrostatic drive assembly. Inside, you get exploded views organized by system: chassis and wheel drives, the 4TNV98C-NMS2 engine with intake and cooling, ROPS/FOPS cab components, electrical assemblies from fuses to ROPS wiring harness, and a substantial hydraulics section covering tandem pump configurations, one-speed and two-speed drive motors, lift and tilt cylinders, and control valves for both hand-foot and joystick setups. Every exploded view carries OEM part numbers so you can order the right part on the first call. Take the quick attach cylinder: it breaks down to rod, piston, head gland, and seal kit at the component level. No more ordering wrong parts. Bookmarked by system; pull it up on your phone, find the component, and place the order.
