New Predator crank to short for Comet 30 driver

[outsider347]

I just purchased a new HF Predator to replace my junk Tecumseh

The drive end of the Tecumseh crankshaft is 2 7/8 long
The Predator drive end is 2.43 long... short by about 5/8 to properly fit the Comet 30 driver

Any suggestions
Thanks Gents

This is a common problem; most use a spacer or, unless I'm mistaken, simply use a longer bolt & loctite in place...

You may want to wait for others to respond before taking my advice...

Thanks for your response Fabroman.

I was hoping for problems to be done with the purchase of the new Predator...not quite i guess

I was thinking about cutting off a 5/8 section from the old crank and using it for the spacer
what do you think

Thanks

You will need to drill the thread out first & cut it perfectly square, otherwise it will not work correctly...

Yes.
I plan to cut off about 1 inch with saws-all , true it up and bore it on my lathe

A cut off wheel on an angle grinder will be a bit neater...

...true it up and bore it on my lathe

Yep, that'll work
