Genuine Bendix remanufactured BA-921 compressors for Detroit Diesel 2007 EPA and 2010 EPA DD13 and DD15 engines are now available for sale in the commercial vehicle aftermarket. Authorized Bendix dealers and distributors will have the advantage of being able to consolidate purchases and expand their offerings.
Commercial vehicles today are using compressed air for more non-braking functions, including automated manual transmissions (AMTs) and emissions controls. A dependable, durable compressor, backed by an OEM warranty and technical support, helps keep these systems operating safely and reliably.
“A clean, dry air supply is essential for today’s trucks, and compressors should pass only a minimal amount of oil, which is needed to lubricate the piston rings,” Nagel said. “The BA-921 unit has always been known for low oil passing, and only genuine Bendix remanufactured compressors maintain that performance. One of the reasons is that we re-hone the piston bore and match the new bore diameter with a new and properly sized piston during remanufacturing.”
Over time, a compressor bore gets worn and scuffed, losing its precise original fit with the piston. Re-honing a piston restores that fit, which is key to ensuring the piston passes just the right amount of oil during operation. A small amount is necessary to lubricate the compressor, but too much oil passing risks contaminating the air supply – which can lead to significant problems.
