FAQ 

1. Can 10R-1971 interchange with C7.1 camshaft?
No. C7 ACERT and C7.1 differ in timing, sensor trigger and cam lift profile, non-interchangeable.

2. Is core return required for this Reman camshaft?
Yes. Core return is mandatory for Cat Reman unit to activate official warranty.

3. Can minor lobe wear be fixed by on-site grinding if no crack exists?
On-site manual grinding is not recommended. C7 ACERT is sensitive to injection timing; hand rework ruins original profile and hardened layer.

4. Does it fit both excavator and industrial C7?
It fits base C7 ACERT platform. Verify engine nameplate and electronic control version before ordering.
