I mentioned that I was looking for engine for a 318 I picked up to a few people around the church and this is the result.  At both churches people are really surprised to hear about my projects and mechanical abilities.  If this this ends up working out I am going to try to give some compensation to my supplier but anticipate he will refuse.  

Make a donation to the church in his name!

Just confirmed my suspicions - digital caliper confirms that it is a 1" crank.  I hope to see if it will fire later today.

And it runs! No smoke and no strange sounds during the time it ran on gas dumped into the carb. I will work on cleaning it up tomorrow afternoon.

Forgive my ignorance, but what was the crank size on the original engine?

BIG crank! But it shouldn't be too hard to build an adapter to fit the 318's input shaft or clutch.

I will measure the clutch off of the Onan tomorrow and post up the info.  

 

I just soaked the set screws on the dual belt pulley with PB blaster and will repeat that tomorrow.

Most Onan's are 1-7/16". Hard to find clutches for. I need one for a B48G.

I may be able to make a sleeve adapter, to slide on the Vanguard shaft, and fit in the bore of the Onan clutch. Just has to be enough difference to clear the keyways.

If there's enough meat on the hub of a different clutch, I can just bore it and cut a new keyway.

Here are some resources that are worth reviewing.  I hesitate putting them in this thread but it seems to have stirred some good conversation so seems appropriate.  These are write-ups on repowers without kits.

Reading says I will need Briggs 841580 stub shaft... ouch.  These vendors shows it with additional parts for the swap.

Cheapest option here:

With shipping to my door it comes out to $142.

 A bit of conversation leads me to believe this engine has 200-300 hours on it. I have a hard time thinking about pulling the heads with them being that low.  If I have to change the gaskets in 200-300 hours that is 10+ years of use for me before I get close to the 700-800 hour window.  Looks like I will install an hour meter and put gaskets on the radar.

That is what I need to make the Onan PTO work on the 1" shaft of the Vanguard.

About how much are they wanting for that? If it's more than $20-30, I have a nice chunk of 2" stainless shafting should do the trick nicely....

 

About the stub shaft: how big is the bolt pattern, and what does it have to clear on the backside? I have a 5" diameter x 4" long chunk of cold-rolled, might be able to make that too.
