Engine Crankshaft: Crank Grinding - .010”/.010” Myth

27/03/2017  The crank bends at each rod pin when that cylinder fires, because the load is applied in the middle of the mains that support the rod pin on both sides. When the shaft bends, it’s the crank web that is actually deflecting, so most of the stress is concentrated on the fillets on both sides of the rod journal. That’s why the crank usually breaks in the fillet radius if it’s overloaded and bent too far too often.

Grinding Coventry Boring and Metalling

03/09/2020  Before re-grinding even begins we test shafts for defects and surface cracks by magnetic particle inspection. Alignment is also checked before re-grinding the crankshaft to the next undersize bearing available. We are also able to reclaim crankshafts by submerged arc welding or metal spraying. Cranks can be balanced or re-stroked and we also offer nitriding and tuftriding processes.

Crankshaft Regrinding Services for cars and vans HT

The crankshaft is probably the single most critical component in any engine and must meet an extremely high degree of accuracy.For this reason, crankshaft regrinding is one of the most skilled jobs performed when remanufacturing your engine. Once reground, your crankshaft will meet the stringent tolerances for journal diameter, ovality, straightness and surface finish as laid down by the bearing manufacturers.

Electronic Crankshaft Balancing + Heavy Metal - Joey

Drilling the holes sideways through the counterweights parallel to the crank rather than perpendicular to the crank is a technique many prefer because it prevents the metal from being flung out at high rpm. After drilling the crankshaft is again spun on the balancer to determine if additional corrections are required. If the crank is for an externally balanced engine (such as a big block Chevy), the balancing will be done
