This 25-page Yanmar 4TNV88-XMS Parts Catalog PDF (OEM #0CV10-G94800) is the factory parts reference for the four-cylinder diesel engine powering GEHL equipment. Every engine system is mapped with exploded views and official OEM part numbers: cylinder block, gear housing, flywheel and oil sump, cylinder head, intake and exhaust manifolds, camshaft and driving gear, crankshaft and piston assembly, lubrication and cooling circuits, fuel injection pump, injector valve and fuel line, starting motor, generator, and complete gasket set. Open to any assembly and you get a detailed diagram with each sub-component called out by its factory number, including line items like piston ring sets, main bearing sets, and camshaft sub-assemblies. Each number traces directly to a factory reference you can hand straight to your dealer. Hunting down the wrong part number wastes your morning. Bookmarked by system; jump to any assembly in one tap and order with confidence.

Yanmar 4TNV88-XMS (GEHL) Common Problems This Manual Covers
Yanmar 4TNV88-XMS fuel injection valve part number needed when one cylinder stops contributing to power p. 16
Check the fuel injection valve exploded view on page 16. Each of the 4 cylinders has its own injector listed separately. Verify your serial number range before ordering, as the standard 4TNV88-XMS and 4TNV88-XMS (GEHL) variants may carry different part numbers. Also pull page 17 for return-line fittings to complete the order.
Manual Section: Fuel Injection ValveCylinder head gasket part numbers confusing, multiple listings in catalog for same engine top-end p. 20
Turn to page 20, Gasket Set, which lists both the standard and NON-ASB (non-asbestos) cylinder head gasket variants. Order the non-asbestos version unless your application specifically requires otherwise. Cross-reference the cylinder head diagram on page 8 to identify all 4 individual sealing surfaces and confirm you have every gasket needed for a complete top-end job.
Manual Section: Gasket SetStarter motor part number hard to pin down, need complete assembly versus sub-component breakdown p. 18
Find the starting motor section on page 18, which covers both the full assembly part number and individual internal components. Determine whether you need a complete replacement unit or just a specific sub-part. For a 4-cylinder engine like this one, there is a single starter; verify the correct part number against your serial number before ordering.
Manual Section: Starting MotorValve guide seal part numbers scattered across head listings, intake and exhaust variants hard to separate p. 8
Open page 8, Cylinder Head and Bonnet, which lists valve guides and valve stem seals for both intake and exhaust valves. The 4-cylinder engine uses separate part numbers for intake and exhaust valve guides; identify which position needs replacement before ordering. Also check page 20, Gasket Set, for the valve stem seal listed there as a separate line item.
Manual Section: Cylinder Head & BonnetIntake heater part number for cold-start preheat system missing from main fuel components list p. 9
Locate the heater on page 9, Suction Manifold, listed alongside the intake manifold assembly. It is a single unit serving all 4 cylinders and is a distinct line item separate from the manifold gasket and clamps. Cross-reference under 'Heater' to confirm the part number, then add the manifold gasket from page 9 to the same order.
Manual Section: Suction ManifoldFuel injection pump parts list unclear when ordering rebuild components, pump versus sub-assembly distinction needed p. 15
Check page 15, Fuel Injection Pump, for the complete assembly part number and individual internal sub-components. Decide whether you need the full pump assembly or specific internal parts before calling a supplier. Also verify on page 17, Fuel Line, that you have all high-pressure line fittings; this 4-cylinder pump feeds all 4 injectors from a single assembly.
Manual Section: Fuel Injection PumpFrequently Asked Questions

What are the replacement specifications for gasket cylinder head?
The replacement part number for the Gasket, Cylinder Head is 129407-01340, and one unit is required. This part is listed in both the Cylinder Block section and the Gasket Set section of the catalog.
