How far can a crankshaft be turned?

Considering this, how much does it cost to turn a crankshaft?Turning a crank around here is about $150. They turn and polish it, check it for straightness, and straighten if needed.Furthermore, how do I know if my crankshaft is damaged? Inside the engine, your crankshaft is held in place by several bearings, which are lubricated by the engine oil. Signs of a bad crankshaft A forging or casting flaw. Insufficient lubrication. Bearing wear. Loose bearing main caps. Distorted bearing bores. Improper bearing clearance. Bearing failure. Keeping this in view, can you turn a crankshaft by hand? The most precise way to rotate the engine over by hand is to place a large socket on the front crankshaft bolt, attach a long ratchet wrench, and rotate the crank. The longer the wrench handle the more precise the movement. Sometimes you will need to shorten the ratchet due to limited space.Do I need to polish my crankshaft?If a used crank checks out OK and you intend to re-use it (with no need to re-grind), each journal can be polished on a crankshaft belt polisher, using 400 grit, stepped up to 600 grit. The journals should not be “mirror” polished, since microscopic scratches are needed to provide oil cling.
