Tech Bulletin – Camshaft Reconditioning

Today’s high horsepower electronic fuel injected engines demand an overwhelming amount of performance from camshafts. Ironically, camshaft reconditioning or replacement is often overlooked at overhaul. Again and again, we hear about mid life camshaft related failures after overhaul. Qualifying a camshaft for reuse with a simple visible inspection does not work and compromises this important aspect of engine performance and reliability.

At overhaul, camshafts must be reconditioned to restore lift, duration, and profile. Camshafts should also be inspected for inclusions, which can lead to failures after overhaul. Anything short of this leaves the engine vulnerable to major early life failures.

In an effort to focus attention on this area of the engine, B&G Machine has invested heavily in camshaft reconditioning equipment and engineering. With 800 masters, we precision-machine camshafts restoring them to their original profile.

REPROFILING THE CAMSHAFT OFFERS

♦ Restores the lobes to proper lift, duration and profile
♦ Significant cost savings versus replacement
♦ Better reliability and engine performance

Every camshaft is straightened to within .0005″, thus minimizing premature wear of the camshaft bearings. Additionally, precise surface finishes can be machined on the lobes while providing a fresh surface for the cam follower to function properly under the high unit lobe pressures and elaborate profiles.

Camshafts are often a weak link in today’s high horsepower engines. But after a B&G overhaul, this “Achilles Tendon” can be made to operate like new. We see the results with customers who consistently tell us they are getting better performance and longer life out of their engines.
