The lifeblood of a crankshaft is the engines oiling system. If you want the motor to last forever, make sure your oiling system is great.

The worst thing you can do is re-grind a crankshaft without making sure the crankshaft is straight.  You have no idea how many times we see wobbling harmonic balancers or wiped-out main bearings because of grinding bent crankshafts.

Crankshafts come in various alloys. If you ‘weld repair’ journals without knowing the alloy, you will have issues down the road.

Not only are spun rods damaging to the journals, but the rods take a beating too.  You have to ensure they are also not damaged.

Every worn-out crankshaft rod journal is egg shaped. It’s normal and expected.

We come across crankshafts of older motors that have been previously ground. Sometimes they are ground off-center either on purpose or by mistake.  Most of the time they can be fixed but some of these fixes can take a lot of time.
