At PARTSMART, we not only have extensive bus knowledge to guide us in the selection of quality high value bus parts, we also know a little about what it takes to design and manufacture a successful family of reliable bus diesel engines and the importance of assuring that they start and operate on a daily basis. We also understand that to be able to take advantage of a bus diesel engine´s potential extended lifecycle proper re-build maintenance or overhauls must be scheduled over time to maintain the bus engine's high level of dependability for your daily operation. This is why we offer you a high quality line-up of bus diesel engine rebuild and overhaul components; including cylinder heads, fan drives, water pumps and overhaul kits. Take for instance an International DT/DTA466 overhaul kit that will extend your bus engine´s service life by at least two-thirds of the original mileage rating, making your engine like new.
