This is the Bosch 0445110508, a new common-rail fuel injector, not a rebuild, for the Yanmar 4TNV98CT 3.3L four-cylinder engine. It is the injector Yanmar sells as 129E01-53100 and John Deere sells as MIU802933. Catalogs list it for the John Deere 244K and 324K compact wheel loaders, the 320E and 326E skid steers and the 323E compact track loader. The engine takes four injectors.

Hard starting, a rough idle, a miss under load, white or black smoke, fuel in the oil or a cylinder balance fault are the usual reasons these get replaced. Common-rail injectors do not tolerate dirt or water, so find out what took the old one out before you fit a new one. Yanmar’s 3.3L common-rail engines use more than one injector number. The 4TNV98C, without the T, takes Bosch 0445110507 (Yanmar 129E00-53100), and catalogs list the John Deere 244K and 320E under both, so match the number on your old injector before you order.

Change the fuel filters and clean out the water separator before you fit new injectors, and keep every line and port capped until it is connected. Use new sealing washers and return line seals, and torque the hold-down to the engine maker’s figure. Check the service manual for your machine to see whether the controller needs the correction code from the new injector entered after the swap.
