Crankshaft Grinding

Journal wear on the conrod and main bearing surfaces can be repaired, old bearings are replaced with oversize bearings. Also seized crankshaft (through lack of oil or pressure) can cause the bearings to lock onto the crankshaft resulting in them being forcibly rotated within their housing causing both distortion and wear: regrinding can fix this. GNRS can grind and polish to any aftermarket bearing specification; this also includes the bearing thrust dimensions. We are one of the few companies who can grind Subaru Impreza crankshafts. We can regrind any crankshaft which will fit onto our machine, ranging from a single piston motorbike engine to a commercial engine.
