New Attachment Air Compressor Group and Lines Groups Have Improved Design
Usage:
3408 Truck Engines
Description of Change: A new attachment air compressor group is available for 3408 Truck Engines. The new compressor is a Bendix Model Tu-Flo 700, which is a replacement for the former Bendix Model Tu-Flo 600. The new compressor adapts directly to the engine, so the adapter and gasket used with the former compressor are not needed. This design prevents the possible leakage of oil at the gasket, which was a problem on some engines. New lines groups are used to connect the new compressor to the engine.
Adaptable To: All 3408 Truck Engines 28V1-up.
