How do you tell if your crankshaft is damaged?
Symptoms of a Bad Crankshaft Position Sensor
- Your Check Engine Light is Blinking.
- It’s Difficult to Get Your Vehicle to Start.
- Your Vehicle is Stalling and/or Backfiring.
- The Engine is Making Your Vehicle Vibrate.
What can damage the crankshaft?
INSTALLATION FAULTS AND WEAR ARE THE MOST COMMON CAUSES OF DAMAGE TO THE CRANKSHAFT AND CRANKSHAFT BEARINGS. Softening of the bearing journals due to previous bearing damage or improper modification work, e.g. excessive regrinding.
What does a bad crankshaft sound like?
Crankshaft bearing noise is also caused by low oil pressure which damages the bearing surfaces and could eventually damage the crankshaft itself. This type of noise is usually described as a rumbling or thumping sound deep in the engine when accelerating.
Should crankshaft journals be polished?
Crankshaft journal surfaces should be ground and polished to a surface finish of 15 micro inches roughness average Ra or better. However, there is more to generating a ground and polished surface than just meeting the roughness specification.
How do I check my crankshaft journal?
An outside micrometer is used to check for crankshaft journal wear. Check both around and along the journals for taper and out of round. Journals wear at the ends or in the middle. Check for roundness at two or more different points; they usually wear the most at (TDC) top dead center.
How hard is it to replace crankshaft?
The repair of a crankshaft is a very difficult and tedious process that requires true mechanical knowledge, and is best left to the professionals. There are various types of crankshaft repair, like polishing, crankshaft pulley repair, canal cleaning, bearing replacement, crankshaft balancing, dressing, and grinding.
Can a cracked crankshaft cause major engine damage?
So, A broken or cracked crankshaft is considered major engine damage. The good thing is that crankshaft damage is not a very common occurrence. Crankshaft damage can happen due to a casting or forging flaw but this is very rare. Today’s quality control systems for forging and machining crankshafts are state of the art.

Why does a crankshaft have to be replaced?
Because, of this process the crankshaft is extremely hard but also brittle. When an engine has a bearing failure, the excessive clearance can cause the crank to flex inside the engine. The crankshaft can wear past the point of grinding and have to be replaced. And, If the crankshaft looks like this the con-rod is most likely not resizable.
