Drag Racing Crankshafts
With photos and words by Steve TempleAs any experienced engine builder already knows, a drag race engine is made up of hundreds of precision parts bolted together to form an assembly that spins at a furious rate in order to propel its vehicle to victory. Meeting this challenge requires that all those parts going into

Engine Bearings and Crankshafts, What makes them [not] tick?
The relationship between the crankshaft and main bearings is an integral one. Any metal-to-metal contact can have catastrophic results, and if the carnage was the result of improper finish or fitment, you’ll likely get to work on your relationship skills again. There are many analogies to explain how its parts relate to the engine as
Crankshafts:Stock and Performance
The crankshaft is the working arm of the engine. All the force generated by combustion and the downward motion of the pistons is focused on the crank throws. The leverage effect of the force exerted on the crank journals twists the shaft and converts the up-and-down reciprocating motion of the pistons into rotational motion of
Crankshafts and Bearings – Keeping the Relationship Strong
Today’s engines typically have very tight tolerances everywhere and the crankshaft bearings are no exception. The truer the crank is in its alignment with the mainline and cylinder bore, the tighter the tolerances can be. Bearings and mainline bores must be very precise because during operation the crankshaft is not actually straight: it is elastic.

Crankshaft Grinding Wheels: Manual Dressing Of The Grinding Wheel Is An Important Factor
Manual dressing of the grinding wheel is an important factor in producing satisfactory work on your crankshaft grinder. The wheel must be dressed each time it is placed on the machine, even though it may not have been removed from the wheel center. Mount the wheel dresser on the grinder table. Bring the rotating grinding
Crankshaft Polishing: Make Sure The Journals On The Crankshaft Are Properly Polished
Today’s 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 today’s engines is to make sure the journalson the crankshaft are properly polished. The oil film between the journals on the crankshaftand the loaded portion of the
Ensuring Bearing Life: Crankshaft Bearings Are Always Replaced When Rebuilding An Engine
Crankshaft bearings are always replaced when rebuilding an engine because they’re a wear component. Heat, pressure, chemical attack, abrasion and loss of lubrication can all contribute to deterioration of the bearings. Consequently, when an engine is rebuilt new bearings are always installed. “Reading” the old bearings can reveal a great deal about conditions that may
