Not everyone,, Im still here, Keep up the great looking work Bruce! I think this thread and its contributors have/will help many in their quest to keep these machines running for a long time. I read on another site Gravely has stopped offering cylinders for the L models,, the options dwindle as time goes by for these fine machines.

Wow, long thread. I am going to be selling most of my Gravely tractors, (3) 2 wheel units and boatload of attachments, (3) 800/8000 series riders and boatload of attachments. I repowered one of the 816s with Onan 18hp several years back and will probably keep that one with the 48" snowblower.
I enjoy the Gravelys but don't have the time anymore to really keep them up. I bought the 2 wheelers for the attachments..
Nice work on the conversions!

Hi folks. You may recall earlier this Summer I put a 13 HP clone on my 73 Superconvertible. It worked but the tractor ran too fast. Since then I had Bruce shave 3/32" off the 1" drive gear shaft so it wouldn't stick too far into the tranny. I also soaked the hi/lo planetary in oil for about a month. Finally I adjusted the hi/lo clutch band. Tried the tractor tody and it worked! Guess that makes me an offical member of the repower club! There is a photo below showing the tractor cutting my back yard today. The 30" mower even put some nice stripes on the lawn.
When I started this I wanted to see if I could make an adapter without doing extensive machine work. To do this I used the front half of the Gravely 7.6 engine crankcase and put a home made aluminum plate on the back. I say home made because it is a simple aluminum plate made using a circular saw and drill press. I did need some machine work done on the gear and bolt used to hold it to the crank - which Bruce did exactly the way I asked. I'm tickled this worked and appreciate all the suggestions made on this forum.

The other day for kicks I typed 'Lifan Engine 13 HP' into Google. It turns out Home Depot .com sells such an engine with recoil start for $259 with free shipping. $60 more adds electric start. That's a pretty good price. The description didn't mention the crank thread. I say this because based on my own experience a 7/16" threaded crank is more difficult to deal with than 3/8". Anyway, thought some might find this interesting.

I looked up these and.
They are some of the best clones engines made.
They have been around for about 15 years:thumbsup:
I agree with ONE the 3/8 X 24 Has a smaller head and works a lot easier then the 7/16 X20 is a large bolt head to deal with.

Two comment and a question:
First, you guys are awesome. I joined to forum so I could say that. I have at least one L that need re-powering, so I'm following your work closely.
Second, I recently installed at Lifan engine from HD on an old mechanical log splitter and must say that the quality of the engine is superb. I needed an integrated 6-1 gear reducer, which Lifan offers, largely for cement mixers, I presume.
Question: I have no engineering background or aptitude, so I'm asking a village-idiot question. Has anyone considered connecting an third-party engine to a Gravely L using a flexible coupling (like the one they once used on Craftsman table saws in lieu of a pulley-and-belt system or the one that was in the Erector set I had as a kid)? I'm thinking it would be easier to find compatible terminations for either end of the coupling than to do all the precise machine-shop work you guys are doing. Plus, if things aren't quite centered or lined up, properly, maybe a flexible coupling would be forgiving. There may be a thousand reasons why it wouldn't work, but if it will, how do you want me to make out the check?
