Barring / Rotate Crankshaft

[WM-300]

I have and have used the Cummins Engine Barring gear on my 4BT's. However, I have always wondered;



What if you have a leaky injector oozing some fuel. Would it be possible for a 'cold' diesel to try to fire when barring? That could ruin your day. Or is there no concern whatsoever.

When barring you don't have the speed to create any heat in the cylinder to ignite fuel... . even IF there were enough fuel in there... which there wouldn't be.

A diesel needs good cranking power (speed) to fire. Most of us who have had a diesel for a few years have run into that situation where the battery gets weak enough to barely crank the engine over... . we just give it up because it's time for a new battery... she just ain't gonna fire.

Hope this helps.

Just use a ratchet and make sure she's out of gear. Let her eat.
