Yanmar 3640, 3840, 4240, 2026, 2041 2008 Parts Catalog

Ordering the wrong part because you guessed a number or used a generic aftermarket list? That costs you hours and sometimes damages the machine. This is the real thing – the OEM Yanmar 3640, 3840, 4240, 2026, 2041 2008 Parts Catalog, straight from the factory. No reprint, no scanned third-party copy. It covers the Yanmar 3TNV88-BKMS (P/N 192473), 4TNV88-BKMS (P/N 192474), and 4TNV88-BDMS (P/N 192494) engines used in Gehl 3640, 3840, 4240 and Mustang 2026, 2041, plus the 2044 and 2054 models. Every part number, every illustration, every torque spec came from Yanmar’s engineering department. You use this catalog to pull the exact fastener, gasket, or seal – not something that ‘looks close.’

Yanmar 3640, 3840, 4240, 2026, 2041 Parts Catalog Coverage

Open to page 1 and you get the engine model breakdown and P/N references. Page 3 – the table of contents – lists every assembly: Cylinder Block, Gear Housing, Flywheel Housing and Oil Sump, Cylinder Head and Bonnet, Suction Manifold, Exhaust Manifold, Camshaft and Driving Gear, Crankshaft and Piston, Lubrication Oil System, Cooling Water System, Fuel Injection Pump. Each section shows an exploded diagram with callouts. You match the callout number to the parts list. That gives you the OEM part number, description, and quantity. No guesswork.

Torque specs are listed in the manual – the table of contents on page 3 includes a dedicated Torque Specifications bookmark. You need head bolt torque? You get the factory value, not a generic range. That matters when you are putting a cylinder head back on a 4TNV88 and you want it to seal the first time. I have seen guys use aftermarket catalogs that list the wrong torque for the gear housing bolts – results in leaks and stripped threads. This catalog ends that.

Torque Specifications: Factory Values for Every Fastener

Every professional mechanic knows that torque is not a suggestion. The Yanmar service life of these engines depends on correct clamping force. This parts catalog does not give you the assembly procedure, but it does give you the torque values you need to order the correct parts. If a bolt is listed with a torque spec, you know what fastener grade and thread pitch the factory used. Cross-reference that with the exploded view on the cylinder block page and you get the exact bolt part number. Do not rely on aftermarket cross-reference charts – they miss updates. This catalog is revision A, dated 06/08 (June 2008), so it includes the latest part number changes up to that date. Your local Gehl or Mustang dealer can confirm superseded numbers, but this gives you the starting point.

Mustang 2026 and 2041: Are These Included?

Yes. Page 1 explicitly states: “Mustang 2026, 2041, 2044, 2054.” Same 3TNV88 and 4TNV88 engine families. If you own a Mustang 2026 or 2041 skid-steer loader, this catalog covers your engine parts. The illustrations match the Yanmar engine tag on your machine. Verify your engine model and serial number – the catalog lists the specific P/N for each engine configuration. Do not assume a 2026 uses the same injection pump as a 2041 – the catalog shows the difference in the Fuel Injection Pump section.

47 Pages of OEM Part Numbers – No Padding

Forty-seven pages. Every page counts. There is no introductory fluff, no marketing text. Exploded diagrams, parts lists, torque specs, and a table of contents. That is it. The pdf file name is Yanmar_3640-3840-4240-2026-2041_2008_Parts_Catalog_en-25414003442.pdf – that is your proof of authenticity. We sell the largest collection of OEM shop manuals in North America. When you access this, you get the exact same document a dealer service writer pulls up.

Aftermarket Catalogs vs. OEM: Why the Difference Matters

I have had customers bring me aftermarket parts lists printed from a generic database. The part numbers are often incorrect – they use superseded numbers or omit the latest revision. That leads to ordering a piston that does not match the ring set. Or a gasket that is too thick. This Yanmar catalog comes from the manufacturer. The part numbers are the ones stamped on the factory packaging. If you need a part for the cooling water system, the diagram on that page shows the water pump, thermostat, and hoses with the exact routing. The aftermarket books often compress multiple engine models into one generic image. Not here.

For context on the automotive and equipment industry, refer to Automotive Industry Overview to understand why OEM documentation is the standard. Also, see Automotive Industry Overview for general background on manufacturer specifications.

Who Should Use This Catalog

Home garage mechanics who service their own Gehl or Mustang skid-steer. Small fleet owners who want to order parts without dealer markup. Professional technicians who need a digital copy on their shop tablet – no flipping through greasy paper pages. Beginners will find the exploded diagrams helpful to understand how the engine comes apart. But this is not a repair manual; it is a parts catalog. You pair it with the factory service manual for assembly steps. We stock related manuals: Yanmar Engine Parts Catalog 2007, Ammann Yanmar B12 B17 1991 Parts Catalog – OEM Factory Specs, and Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs. Those cover different engine families.

Bottom line: if you need to order a cylinder head gasket for a Yanmar 3TNV88 in a Gehl 3640, this catalog gives you the part number. If you need the torque value for the crankshaft pulley bolt, it is inside. Do not waste money on parts that do not fit. Access the Factory Manual now and keep it on your phone or tablet.

Does this catalog include torque specifications for the cylinder head?

Yes – the table of contents lists a Torque Specifications section. Use those values to select the correct fastener and torquing tool.

How do I use the part numbers to order from a dealer?

Locate the correct exploded diagram for your engine model (e.g., 4TNV88-BKMS). Note the callout number, then find that number in the adjacent parts list. Copy the OEM part number (e.g., 192473-xxxxx). Take that number to your Gehl or Mustang dealer. They will verify current supersession. The catalog is dated 2008, so some numbers may have been updated – but this gives you the original factory reference. Always confirm engine serial number when ordering. Do not assume the same part fits both the 3640 and the 4240 – the catalog shows differences in the Gear Housing and Cylinder Block sections.
