Applications:
Used on Caterpillar 3176, C15, C16, C12, C10, and 3406 engine applications requiring a 3-bolt, 22-spline TF-550 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.
