Tackling 4×4 Known Issues

Feedback from workshops is highly encouraged by Exedy as the information provided is often used as the basis for technical bulletins supplied in their clutch kits.

FORD RANGER DAMPER FAILURE
This was the case in recent times when the technical team at Exedy were alerted to an issue where a loss of pedal pressure had occurred with a customer’s 3.2L PX model Ford Ranger. The vehicle in question had approximately 140,000kms on the odometer and, although the clutch had been replaced not long beforehand, it was feared the concentric slave cylinder may have failed resulting in the loss of pedal pressure. Initial investigations back at the workshop however had found no evidence of leaking fluid from within the bell housing and when attempting to re-bleed the system, the technician quickly traced the leak back to a hydraulic damper along the delivery line located on the vehicles firewall. While the damper appeared intact it was found that fluid would escape from the damper as the clutch pedal was depressed.

After being removed from the vehicle for closer inspection, it was found that polymer body of the damper had perished over time and fractures found on the base of the damper had allowed the fluid to escape Feedback from workshops is highly encouraged by Exedy as the information provided is often used as the basis for technical bulletins supplied in their clutch kits. TACKLING 4×4 KNOWN ISSUES under pressure. Following installation of the replacement genuine Ford damper, successful bleeding of the hydraulic circuit and consistent pedal pressure was restored. Due to the above feedback, Exedy now include technical “Note 113” in each applicable Ford Ranger/Mazda BT-50 clutch kit to assist fitters with identifying a suspect faulty damper. To ensure a successful clutch replacement, Exedy believes it is essential to inspect the condition of the entire clutch system and that all suspected faulty parts be replaced.

NEW TO RANGE COOLMASTER 4X4
TRANSMISSION COOLERS

One of the most common calls Exedy fields day-to-day relate to transmission external oil coolers. Today’s multi speed transmissions have to contend with everincreasing operating temperatures due to increased vehicle loads and towing capacities, coupled with inadequacies of OEM in-built cooling systems. The resulting excess temperature is a common cause of premature transmission failure. Exedy is pleased to announce the addition of the Coolmaster Off Road Transmission Cooler Kit to suit Ford Everest and VW Amarok into the Exedy range. Whether your customer is towing a boat, carrying a heavy load or just in heavy traffic, the cooler transmission kit will help to protect the transmission from overheating and premature failure.
