What is Crankshaft Grinding Capital Reman Exchange

The bearings used should match the proper OEM clearances for oil flow at the diameter of the journal. Some crankshaft rebuilders will undercut the crankshaft. Undercutting the crankshaft journals and then welding them back up will strengthen the crankshaft. Some cranks are unsuitable for grinding because they are well below OEM tolerances.

» Centerless grinding of cam and crankshafts

Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are Camshafts are rough ground directly from the cast condition while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts. The two main things are lobe lift and journal diameter. For example a .420-inch lobe lift roller cam should finish around 1.028-inch base circle size. When you request a .900-inch cam you are taking .128 inch of base circle diameter away dropping the lifter down an additional .060 inch in the lifter bore.

Chevy Big-Block Performance Camshaft and Valvetrain Events

For a Chevy big-block the lobe lift of the intake is a very important factor. Because the cam is physically bigger (1.950-inch journal diameter) than a small-block (1.872-inch journal diameter) the lobe can for a given duration have a higher lift. However be aware that many cam companies use the same profiles for a small-block. When a crank or cam is polished on one of these machines it uses about one inch of tape per journal so fresh abrasive is used for every polishing job but because it s such a small amount many users say they ve saved money. "One PER reported a 50-75 percent savings in the cost of

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 upon camshaft 4 5 • Broad range of grinding solutions for camshafts cam pieces and individual cams • Non-cylindrical OD/ID grinding • High utility value through adjustment to respective grinding assignment • High long-term precision due to hydrostatic round guides • Maximum repeat accuracy thanks to CBN or diamond abrasives • Minimized undulations due to grinding wheel balancing on two levels
