Applications:
Used on Navistar DT466 and HT-series diesel platforms requiring a TF-550 compressor with 11-tooth tapered accessory drive and vertical top discharge configuration. The compressor supplies air for service brake and auxiliary pneumatic systems and is typically replaced due to reduced air output, oil carryover, overheating, or internal wear.
