Subject: Compressor Crankshaft Upgrade
Bendix has alternate part numbers available for certain Bendix® Tu-Flo® 550 and Tu -Flo® 750 compressors used
for Cummins and International through-drive applications. High strength materials are used in these compressors
to carry the higher forces that are sometimes found in the applications below and which could lead to compressor
crankshaft fatigue fracture.
Please see below for a list of compressors being offered by Bendix at this time.
