452-2504 front camshaft for CAT engine spare part

Product Advantages

1.Cam profile follows original 3512B specification to maintain stable idle and uniform combustion under high power.
2.Tight coaxiality control on multiple journals reduces uneven wear, designed for long-hour continuous running.
3.Heat treatment tuned for constant-speed generator duty, lowering spalling risk under cyclic load.
4.Direct OEM replacement with standard timing reference, no timing scheme modification needed during overhaul.

FAQ 

Q: Can front camshaft 452-2504 interchange with rear camshaft 452-2501?
A: No. Cam lift and phase angle are different for front and rear cylinder banks. Reversed installation causes valve-to-piston collision.

Q: How many pieces of this camshaft does one 3512B engine require?
A: One 3512B V12 engine uses one 452-2504 front camshaft plus one 452-2501 rear camshaft as a set.

Q: Can reground journals with undersize bearings be used for repair?
A: Not recommended. For generator continuous duty, reground camshaft has much shorter fatigue life and may fail unexpectedly.
