Is there a certain way the flywheel goes on?

[MTownsend]

I have just been told that the flywheel has to go on one way in relation to the crank shaft??? I just bolted it on and torqued it to 101 ftp and callded it good is this wrong?

The manual says to mark the relationship of the flywheel to the crankshaft before removing so it can be put back in that position. The reason for this is that the set was probably balanced as a unit when new. If you don't know where it was when you removed it, then you don't have much choice. You have one in eight chances of it being right. I think if it were me I would start it up and see if there is noticeable vibration before installing the transmission if that is feasable. bg.

I Bought a diferent flywheel for the truck, and I have the cab off right now. So I don't know how to get it to run. If you put power to the fuel soliniod and get the starter to turn over will it run?

I just got done speaking to the fine folks at AutoWorld in Greatfalls MT. The verdict is that my engine is neutral balanced and it doesn't mater how the flywheel is bolted on.

Man I was getting worried there.



Thanks

FYI



I just went through the 1989 & 93 FSM and the only thing to get witnessed marked is the pressure plate to the flywheel, it doesn't mention anything about flywheel to crank. In my experience anytime there is a required position of the flywheel to the crank at least one of the crank bolt holes is offset from the others to ensure proper positioning on install.

OK, I marked the old presure plate on removal, but plan to use a differant one ? As I recall replacements are not marked. Now what ?

Install, you are good to go. bg

Sometimes we get an engine that was not built to our application spec and it will have the wrong flywheel. We simply install the correct one with no concern for bolt hole position. If it is mentioned in a manual somewhere, it must be a generic statement not actually applicable to the Cummins. If you had the engine balanced with the flywheel, then you would want to reference the position of the flywheel to the crank.



Run it.
