1947 clutch

Postby Josh_boro » Wed Aug 16, 2023 10:57 am

Hello everyone, I’m getting ready to have the engine professionally rebuilt on my 47 cub. While the tractor is split I’m putting in a new clutch. What clutch will I need for my tractor? I know there is 2 different types.

If the serial number plate has a "J" on it, your clutch is a Rockford which was the most common. The other type was an Auburn.

If you are replacing the whole thing, it doesn't matter which type the old one is. They interchange. That said, a lot of the available replacement clutch parts are not of as good quality as the originals, or even as good as replacement parts that were available years ago. I would inspect the old parts and reuse them if they are in good serviceable condition.

Hi,
Below are pics from TM Tractor Parts of the 2 brands of clutches.
The 1st pic is the Rockford.
The 2nd pic is the Auburn.
TM Tractor Parts has good quality clutch parts, people on here have said.
They say on here to soak a new throwout bearing in light oil for a day or more before putting it in.
Grease the grease fitting with cheap grease so the oil in the grease will absorb into the bearing material.

About all I have seen that are made nowadays are the Rockford style. I don't know who makes the replacement ones.
I sent you a PM.
