JASPER’s Diesel Division will have an additional 12,000 square feet of work space by
October 201

In addition to remanufacturing a complete line of diesel engines, Jasper Engines & Transmissions offers a selection of diesel engine air and fuel system components, including fuel pumps, injectors and turbochargers.

Sales of air and fuel components has steadily increased, and JASPER believes it could be one of the company’s top divisions in the next five to ten years.

In preparation for this growth, and overall Diesel Division expansion, JASPER is adding 12,000 square feet of work space to its Wernsing Road remanufacturing facility. This project is scheduled for completion by October.

Diesel air and fuel components offered by JASPER include high pressure oil pumps, like the Bosch Rexroth Pump and Sheppard Pump, the Stanadyne DS and DB2 pumps, along with a variety of Caterpillar Pumps. Every fuel injection pump is thoroughly tested and calibrated using sophisticated test equipment.

All Bosch injection pumps are calibrated on a state-of-the-art Bosch 815 calibration stand. HEUI high pressure oil pumps are tested on a custom-built test stand to provide a live simulation of in-the-vehicle operation.

Injectors include the HEUI 7.3 and 466, the 6.0 and 6.4 Bosch Common Rail and other popular applications.

As a Service Dealer for both Bosch and Stanadyne, JASPER’s Diesel Air and Fuel Component Division employs Associates who have been trained in original equipment specifications and processes.


JASPER is a Service Dealer for Borg Warner and remanu­factures, and stocks, most popular Borg Warner turbocharger applications. JASPER also remanufactures Garrett and Holset applications, plus many more. A core balancer and state-of-the-art component balancer are used in the remanufacturing process of every turbocharger. This assures exact component balance in order to assure optimum turbocharger performance and life.

In addition to the air and fuel components, JASPER of­fers accessories for the very popular International/Ford 6.0L diesel engine. These accessory items include heads, FICM (Fuel Injection Control Module) and EGR cooler.
