I'm not sure what the flexible connector you are referring to looks like. Another member of this forum, Oldmech, used a flexible connector as part of his solution to repower a Gravely L. So you might look at what he did and see if that's similar to what you are thinking.

Thanks for sharing your experience with the Lifan engine. There seems to be a consensus that Lifan makes a very good engine. I have never used one.

Two comment and a 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?

Hi Guys
I finally got a gear done for the L model that I think will work.
I will use a top hat or bushing on the end like Gravely uses
on the late model.
I took a gear Martin S1015
and a 1 inch coupling bored the coupling out left about .002 small.
Pressed the gear hub into the coupling with a key all ready in coupling .
Welded them together.
Bored the gear end out so engine crank shaft can go all way through.
Also machined a pocket in the gear end for the top hat to fit.
Machined off to fit on the engine shaft length.
Now all I like is having it harden.
and make the top hat and have it harden. :thumbsup:

This also shortened the length that the crank holds the gear out from the engine about 1 1/2 inches.
now I will only need 1 spacer adapter
More pictures :thumbsup::thumbsup:

Lookin good Bruce,, cant wait to see the finished product!

 

[gravelymay]

I plan to make a top hat like the pilot bushing gravely makes for the late model gear.
As a matter fact the only difference will be the Outside dia.
of the large dia :thumbsup:

Also here is the other mod.
I had talked about before .

I second that. This is good stuff - very creative! I'll be interested in seeing how a clone type engine fits on an L using this gear and adapter. As the space between the engine and tranny decreases, parts of the engine may start running into the handle bars. The muffler will hit first followed by the the gas tank. So some work arounds may be needed for these - but I'm sure Bruce will solve them.

 

[gravelymay]

Thanks man
I think I will take the gear to Richard's show with me.

If anyone wants to look at it to get Ideas :thumbsup:

I've not put one on a L yet but the bolts and handle bars hook at the same place up front.
So I think I can make it nearly like a 10 and later models.

Looked at my L again and determined that if I moved the engine up closer, the muffler would hit the left handle bar first followed by the gas tank which would hit the hi/lo and swiftamatic rods, not the right handle bar. These rods could be bent out the way without too much difficulty. Would love to see pics when you do an L.

Yelp The L model ??????:confused2:
I plan to try to do a L as soon as I get through Two swap meets.
You Know more about them then I do on them.
I look at things strange some times.
I have in my mind what I want,
But some times it don't come out that way.

Hey One.
Is the tractor still doing its stuff?

 

[Oneaxepony]

Hey One.

Yeah. Now that its repowered I have to fix some oil leaks - both axles, axle housings (where the 6 bolt castings attach to the main body), and the swiftamatic shaft that goes into the right axle housing. Might do some this Fall and some next Spring. I'm in no particular hurry...

Hey One
Are you going over to Richard's swap meet Sat?
I would like to see you in person.
I plan to be there.

Not sure yet. Would like to go but there are some complicating factors like my 30th wedding anniversary. Will know later in the week.

Looks like I'll be going after all. Hope to see Bruce and others there.

 

[gravelymay]

I am in Pittsburg Pa.
So I plan to be there tomorrow
I also brought the new Gears with me.
I didn't bring a tractor or engine.:thumbsup:

Went to the swap meet today in WV. Got there late so I missed Bruce who was apparently there earlier in the day. Talked with Richard and he said Bruce was there and showed him his gear which could be used on an L repower. Show was fairly small but if you needed parts there were plenty to be had. There were other things going on too: a tractor pull, hit and miss engine dispay, a couple of nice David Bradleys, and if that wasn't enough - there was a quilt show. Picture perfect weather!

 

[gravelymay]

I was there and now I am gone.
I stayed until about 2.30 had to get back to Pittsburgh.
For a surprise birthday party for My son.
Sorry I missed you maybe next time.
