Part of the Yanmar Parts Manuals.
Genuine Yanmar factory parts data across 47 pages: OEM catalog #917329 covers the 3TNV88-BKMS engine fitted to the Gehl 3640 and the Mustang 2026 and 2044 skid-steer loaders. Exploded assembly views sit alongside itemized parts lists for all 17 engine systems, from cylinder block and gear housing through the fuel injection pump, governor, injection valves, and full gasket set. A numerical index ties every component back to its diagram, so finding part #182130 (fuel filter) or #194315 (oil filter) takes seconds rather than a trip to the parts counter. Confirm the exact OEM crankpin bearing number before you order, not after you've split the engine. No more misreads off a worn tag or guesswork over the phone. Download it, jump to any system through the bookmarks, search any part number by keyword, and order right the first time.
