Applications:
Used on Caterpillar 3304, 3306, 3406B, and 3176 engine applications requiring a 22-tooth spline TF-750 compressor configuration. The compressor supplies air for heavy-duty service brake and auxiliary pneumatic systems and is typically replaced due to reduced air delivery, oil carryover, overheating, or internal compressor wear.
