Hi! Congratulation ! Very good work Bruce . I have a BCS a Grillo and a Gravely L model . The best tranny is on Gravely True Shuttle live PTO very reliable. A Masterpiece of engineering. So Gravely are very valuable tractor for rebuilt with a new engine. Good Luck! Oldmech

Thanks Oldmech
I will have 10 of these gears by Friday
Boy we have talked about this for 3 Years.
I have a C10 That I am going to put one as soon as I get them.
Because it has the same gear as the L model.
I will show pictures.
thanks again.

gravelymay,

I need to repower my Model L. However, it only has a 2-speed transmission. Will a modern engine work? Will you also be making adaptor plates? I would really appreciate any help you can give (or sell - if you are willing sell the parts you are making).

Thanks,

Greg

Hi Greg
Right now I have the adapter thickness nail down for the C10.
I am using the old Kohler adapter and making a spacer .
Because the 1 inch cranks are longer.
Now to the L Models.
I plan to use a old Kohler adapter plate redrill it to fit the Model L Transmission
I have not nailed down how Thick the spacer will need to be.
The gear I am having made will fit on all the 1 inch engines.
Some will be different lengths
So I will have to come up with different spacer thickness
Yes I plan to sell the
Spacer ,Gear,and the pilot bushing.
These 3 pieces will run $250.00 plus about $15.00 shipping
The gear is 150 by it self
The spacer is made from a 8" round 2" thick
So it is not cheap.
I can get the muffler cut out for $40.00 swap.

Hey Bruce - cant wait to see how this works on the C10. On another note, think we discussed this once before somewhere - is it possible to shorten the crank on a 13 HP clone without removing the crank? Think you told me this is possible. If so, how would you do it and still keep the new face exactly perpendicular to the shaft?

 

[gravelymay]

You would have to have the crank turning.
So you could start the engine and use a slitter blade.
On a 4 in side grinder.
I would drill and tap the hole deeper before you start.

Here is a C10 repowered with a old Honda engine
I had to notch the muffler also.
The engine and transmission is still dirty.
but the picture will give you a Idea how they fit.

Never heard of a slitter blade. Does this have fine teeth? Do you hold it by hand? I assume the 4" side grinder is an angle grinder? Just trying to visualize how to do this. What spurred this is the cranks on the Honda/Clones are typically much longer than they need to be for Gravely repower. So why not cut the crank down and eliminate some spacers? That would work for what I did.

Also - the C10 photos you just posted - is that an old project or one you're doing right now? Thanks.

This is the C10 That I just got in to change
To a old Honda that he Had bought at flea market for about $150.00
So I am not cleaning it up except where it mounts up.
Here is a picture of a speedy cut .
I am using on a trailer frame to cut gaps.

Hi One
Did you understand what I was talking about?
The side grinder Has a slitter or speedy cut blade.
The blade is about 1/32 thick grinding cut off type blade.
Will cut anything Hardened Steel ,Stainless steel.
Just don't get anything in the way you don't want cut.

I didn't get my gears yet.
He was having a problem with the dead end broach.
So he had to order a new one.
