Jasper Engines & Transmissions says it is now offering rebuilt turbochargers from Holset, Garrett and Borg Warner for Ford’s 6.0-liter and 7.3-liter diesels, Cummins’ ISB engine and several Caterpillar engines.
Jasper says it has more than 100 different stock numbers on hand.
Jasper says it disassembles and oven-bakes the housings in excess of 700 degrees to remove soot and debris from the casting as part of its remanufacturing process.
The company then inspects and balances the internal component to ensure proper tolerances before reassembling the center section. A high-speed core balancer balances the rotating assembly at speeds in excess of 70,000 rpm.
“For years, we’ve relied on several suppliers for our turbo needs,” says Ryan Dooley, Jasper’s turbo and fuel division manager. “We value those relationships, but if we wanted to take our product to the next level, we had to get in the driver’s seat and bring the entire process in-house. When a center section spins at 80,000-120,000 rpm, bearing housing journal finish is essential. With our years of experience in engine remanufacturing, both in cylinder walls and deck finishes, JASPER polishes bearing housing journals to a finish of 35 RA or less, which will meet or exceed any industry standard.”
Jasper offers a one-year parts and labor with unlimited mileage warranty on its rebuilt turbos.
