yes you can reuse a crank make sure the jornals are clean no dull spots on them. everything should have a mirror polish. also check around the oil holes in the crank. when the crank fail they usually break at this point.

Should I replace connecting rod bolts?

Torque-to-yield (TTY) rod bolts should not be reused doe to the risk of breaking or stretching. For performance applications, don’t even think about using or reusing stock rod bolts. Replace them with stronger aftermarket bolts. Installing the rod bolts correctly is essential to preventing rod failures.

Can main bolts be reused?

If a head bolt is rusted it should not be reused. A head bolt should not be reused if the threads are galled or badly damaged. Chasing damaged head bolt threads with a die will clean up the threads but also remove material (metal) and undermine the head bolt’s ability to torque down and hold to specs.

Some shops will try and reuse anything that can be refurbished. That means you can bore block castings and anything you can refinish the wearing surface of. “If wear doesn’t adversely affect the function of the part, you can reuse it,” Anderson says.

Can you reuse a crank with a spun bearing?

Why do Conrods Bend?

Con-rods bend most commonly due to hydraulic action caused by the induction of water. (Blown head gasket or driving through water above the air intake.) Severely bent con-rods should be replaced not re-aligned. Minor bend can occur due to severe operating conditions.

Can an engine run with a broken rod?

No. If you’ve actually thrown a rod, that means there’s already a lot of destruction going on. A thrown rod means a portion of the rod is being thrown around inside the engine. As you run the engine, it will continue to cause more destruction.

What causes rod bolt failure?

Sparks says the most common reason for rod bolt failures is failing to install the rod bolts so that they achieve the proper clamping load. That’s the complicated way to say “aren’t torqued right,” but that can be misleading because it’s the use of a torque wrench that causes most of the problems.
