Overview

Put the Detroit's accessory drive back under proper tension with this Continental Elite Accu-Drive HD automatic tensioner assembly distributed by FleetPro Parts & Tires. It fits Detroit Diesel DD13, DD15 and DD16 engines across the EPA10, GHG14, GHG17 and GHG21 emissions eras, which covers most of the Freightliner and Western Star tractors on the road today. A tensioner with a weak spring or a rough bearing hands you belt flutter, squeal and premature belt wear, and the truck comes back for a second belt when what it needed was this. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Heavy-Duty Tension Control: The Accu-Drive HD Advantage

At 11.03 lbs, this is not a small part, and that weight is the story. The Accu-Drive HD tensioner is engineered for the accessory drive of a big-bore Detroit, where the spring has to hold constant load on a wide serpentine belt through every load step the engine produces, and the pivot and pulley bearing have to survive that cycle for years without going rough. Light-duty tensioner design does not survive here, which is exactly why the failed one is coming off.

It is supplied as a complete assembly, so the spring, arm and pulley all go on together and the repair actually addresses what failed. Shipping in an 11 x 8.5 x 5.5 in carton, it moves as a normal parcel, which makes it practical to stock ahead of the failure rather than to chase after it.

At FleetPro Parts & Tires, we know the front accessory drive is a system, not a parts list. Change the tensioner with the belt while the front of the engine is open and the whole drive goes quiet as a set - a fresh belt on a fatigued tensioner will flutter, squeal and wear out on precisely the schedule of the belt you just removed. This assembly covers Detroit DD13, DD15 and DD16 engines from EPA10 through GHG21 in Freightliner and Western Star applications.
