FAQ 

Q: Can 179-3439 fit 3406C engine?
A: No. 3406C and 3406E differ in fuel system and cam lift parameters, not interchangeable.

Q: How many 179-3439 camshafts for one 3406E engine?
A: 3406E is inline 6-cylinder, only one 179-3439 camshaft required per engine.

Q: Can lightly scored journals be reground for reuse?
A: Regrinding is not recommended. For mining heavy-duty operation, reground camshaft has much shorter service life and may fail unexpectedly.
