Camshafts control the opening, closing, lift and duration of valves. This means precision is essential to engine power, pick-up and fuel economy. Wear on your camshaft will cause excessive valve noises, engine roughness when idling, a lack of power and erratic operation. Maximum horsepower and other engine benefits depend ...Sep 01, 1998 Click Here to Read MoreAdvertisement Todays high output, close tolerance enginesare more dependent than ever on quality remanufacturing procedures,durable parts and precise machining. One of the best ways to assurelong bearing life in todays engines is to make sure the journalson the crankshaft are properly polished. The oil film between the journals on the crankshaftand

The relationship between the cam and lifter in a flat tappet cam is critical, explains Popp. The taper and the crown of the camshaft lobe isnt flat across.If the cam timing is lost during high revs broken chain or gears the con rods will contact the camshaft causing the cam to be broken. Other serious damage can occur at the same time causing the block to be unserviceable. OHC engines break camshafts usually after a seizure of a cam journal in the head. The camshaft breaks between the seized ...Jun 14, 2006 The first of these is usually measured, for a hydraulic cam, at 0.006 inches and, for a solid cam, 0.020 inches 6 or 20 thousandths of cam follower lift, while the second is at 0.050 inches 50 ...

I also discovered that camshafts can be modified but theres a huge risk I recommend buying a custom cam in most cases. Updated information includes my experience with latest generation of cranks, breathing and better ways to modify Boyer-Bransden ignition systems to suit an offset-crank British twin. Geoff Collins June 2007Following these precise machining procedures, our cranks undergo a second high pressure wash cycle to guarantee the removal of any debris that may have adhered or become dislodged during the grinding process. Absolute cleanliness is necessary for the next step of crankshaft remanufacturing, which is micro-polishing and or balancing if needed.
