Jasper Engines & Transmissions is aware of several aftermarket relocation and heat exchanging devices that are being marketed with claims that they decrease the operating temperature of the Stanadyne DS Pump Mounted Driver (PMD) improving its reliability.

These devices often involve modifications to be made to the wiring harness between the engine and the injection pump. The PMD is located on the side of the injection pump in an effort to dissipate the tremendous amount of heat it creates during operation. The fuel passing through the injection pump helps to dissipate that heat efficiently and consistently during all engine conditions. Other methods of cooling cannot maintain this consistency throughout all conditions that may be encountered.

Another issue that arises from the relocation of the PMD concerns the wiring harness. By moving the PMD the harness may be extended, spliced into, or stretched to make the necessary connections. This causes numerous problems from added circuit resistance, poor connections, and voltage drops across splices. These can cause symptoms that lead technicians to replace the injection pump, or the PMD, unnecessarily. Symptoms like hot stall, no start, and fuel control solenoid DTC’s are all commonly immediately diagnosed as a failed PMD or Injection Pump, and in many cases are simply circuit related issues.

Each injection pump JASPER sells is coated with a sealing lacquer in all critical areas including the PMD and the harness. JASPER has spent several years monitoring DS injection pumps that have been returned from the field after being diagnosed as defective. We have determined that relocation, and aftermarket heat exchangers, are not beneficial to the life of the PMD or the reliability of the injection pump as a whole.

The Differential Division of Jasper Engines & Transmissions tackles the job of remanufacturing the Jeep Grand Cherokee independent front suspension differential from model years 2005 and up.

Prior to 2005, Dana Corporation was the main source of drivetrain components in many Jeep products. In 2005, Jeep made a design change from a solid front axle to an independent front suspension.

“Jeep uses two hefty snap rings to adjust carrier bearing pre-load and backlash”, says Wayne Mehringer, JASPER Differential Division Manager. The snap ring in Figure 1 measured .174 thick! It requires a modified pair of retaining ring pliers to keep the ring compressed for installation. “A pinion depth shim located under the pinion bearing cup is also much thicker than the ones used in previous applications, said Mehringer.” The shim in Figure 2 measured .213 thick.

In order to properly adjust this version of the Jeep Grand Cherokee front differential, JASPER keeps in stock 98 different-sized snap rings and 75 different-sized pinion depth shims. Each component varies in thickness in .001 increments. “JASPER must keep these components in stock to properly set these units to original equipment specifications,” added Mehringer.

So when a Grand Cherokee comes to your shop needing an independent front suspension differential, give JASPER a call. Each differential is covered by JASPER’s 3-Year/100,000 mile nationwide transferable parts and labor warranty. Full warranty disclosure is available on our website or upon request.
