We carry the full range of Yanmar 3TNV88 engines for the Takeuchi TB235 - mechanical injection and electronic common rail, new surplus and rebuilt - and we build each core to the configuration your compact excavator needs. The Takeuchi TB235 is a 3.5-ton class compact excavator, successor to the TB135 in the US market. The factory engine code is 3TNV88-BPTB2. CRITICAL INJECTION NOTE: late TB235-2 and TB230 machines were fitted with the 3TNV88F instead - an ELECTRONIC GOVERNOR engine with EGR. Yanmar built the 3TNV88F specifically because US regulations require an altitude-compensation system on the injection pump, which can only be implemented with electronic governing. A mechanical 3TNV88 is NOT a substitute for a 3TNV88F machine, and this is the single most common ordering error on this platform. Confirm the exact suffix on your data plate. ENGINE SPECIFICATION. Three cylinder, four cycle, liquid cooled, vertical in-line. Direct injection, naturally aspirated. Bore and stroke 88 x 90 mm. Displacement 1.642 L (100.2 cu in). Around 36 hp at 3000 rpm at full speed, less in machines governed lower. Dry weight approximately 341 lb (154 kg). Rotation counterclockwise viewed from the flywheel end. Engine as fitted to this machine: 3TNV88-BPTB2. Production years: current. Rated output in this machine: approximately approx. 25 hp. WHAT WE FIT TO YOUR MACHINE. On a compact excavator the bellhousing and flywheel must mate to the hydraulic pump drive, the oil pan has to clear the undercarriage, and the throttle has to answer the machine's engine control. All of that is external and transfers from your old engine onto the replacement core. MECHANICAL OR COMMON RAIL - THIS IS THE ONE THING YOU MUST MATCH. The Yanmar 3TNV88 comes in two fuel systems and they are not interchangeable. MECHANICAL INJECTION uses a mechanical pump and governor, with no ECU or sensors - this is what most machines in the field run, and it is our standard stock. ELECTRONIC COMMON RAIL (HPCR) is ECU-controlled, fitted to machines built to the later emissions standards. We carry both, in new surplus and rebuilt. The suffix on your data plate - codes like -BKMS, -BPTB2, -QTB - does not mean a different engine. The core is the same across the family: same block, same crank, same 88 x 90 mm bore and stroke, same 1.642 L. The suffix tells you the fuel system and the accessory package. The accessories are external and swap; the fuel system is what has to match. Two other variants to know about: the 3TNV88F has an ELECTRONIC GOVERNOR with EGR and is a different engine again, and the 3TNV88-GGE is a fixed-speed GENERATOR engine, not a machine engine. There is also a 4-CYLINDER 4TNV88 that is not the same as this three-cylinder engine at all. Full breakdown of every variant, and how to read your data plate: see our Yanmar 3TNV88 engine buying guide. WHAT WE NEED FROM YOU. A photo of the engine data plate - model, suffix, serial - and confirmation that it is going into a Takeuchi TB235. From that we work out the bore, the cylinder count and the fuel system, tell you what carries across from the old engine, and price you on the right core. Mechanical or common rail, new surplus or rebuilt, we have it.

Looking for a 3TNV88 for a Wacker Neuson 5003? We hold this engine in mechanical and in common rail, new surplus and rebuilt, and we build the core to match the mini excavator it is going into. Send the data plate and we will confirm which one you need. The Wacker Neuson 5003 is a 5-ton class mini excavator built for utility and general construction work, powered by the Yanmar 88 mm-bore 3-cylinder. ENGINE SPECIFICATION. Three cylinder, four cycle, liquid cooled, vertical in-line. Direct injection, naturally aspirated. Bore and stroke 88 x 90 mm. Displacement 1.642 L (100.2 cu in). Around 36 hp at 3000 rpm at full speed, less in machines governed lower. Dry weight approximately 341 lb (154 kg). Rotation counterclockwise viewed from the flywheel end. Engine as fitted to this machine: 3TNV88. Production years: 2010-2020. Rated output in this machine: approximately approx. 36 hp. WHAT WE FIT TO YOUR MACHINE. On a mini excavator the core engine is only half the job. The bellhousing and flywheel have to mate to your hydraulic pump drive, the oil pan has to clear the undercarriage, and the throttle has to answer to the machine's engine control. Those are all external parts and they carry across from the engine you are pulling out - we build the core to suit. MECHANICAL OR COMMON RAIL - THIS IS THE ONE THING YOU MUST MATCH.

Send us a photo of your engine data plate - model number, suffix and serial - and tell us it is going into a Wacker Neuson 5003. We will confirm the bore, the cylinder count and the fuel system, tell you which accessories carry over from your old engine, and quote you on the correct core in mechanical or common rail, new surplus or rebuilt. If what you asked for is not right for the machine, we will say so before we take the order.
