  • What is Crankshaft Grinding? Capital Reman Exchange

    Indicators that a journal needs grinding include if the surface has wear and make it rough to the touch. Sometimes the journal will be knocked out of center and needs to be surfaced to round and straightened. Consequently, the journal diameter could be positioned out of square at both end of the pins. Each grind is different but all crankshafts can be ground to allow for more or less stroke

  • Crankshaft grinding with JUNKER grinding machines

  • What is Crankshaft Grinding? Capital Reman Exchange

    The main reason crankshaft grinding is done is because the crank wears over time. Over thousands miles the end play between the crankshaft and the bearings increases. When the “fit” between the bearings and the crank isn’t perfect it lowers oil pressure and decreases lubricity. The less oil to the crank the faster it can wear out. When you reduce the size of the bearings you reduce the overall surface area too. Less

  • Crankshaft grinding with JUNKER grinding machines

    A crankshaft is made up of the following components: Main bearings: Centric diameters that define the rotational axis of the crankshaft. Pin bearings: Receive the connecting rods, which turn the energy into rotational movements. Crank webs: Connect the main bearings to the pin bearings. Crankshafts can be forged or cast. Forged crankshafts are produced using a complicated forging method, and cast

The machinist should be very careful to only remove minimal stock for a “clean-up” of the crankshaft surface. In most instances a remanufactured crankshaft does not require grinding of the thrust face(s); so the grinding wheel will not even contact them. Oversize
