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.
WHY THE 3TNV88 REPLACES THE 3TNV84.
Yanmar's TNV three-cylinder engines are one family on one architecture - same 90 mm stroke, same block design, same mounting and accessory layout. Only the bore changes: 82
