How do I repair the drive chain on an old sully rake

[MIKE R]

What am I looking for? There are stampings here and there on the gears and wheels that don't mean anything to me.

You should look for raised markings with letters. They would look like a company logo and they will be on most is not all cast parts. Here is an example of casting marks on my 1925 Massey Harris Mower. Take note of the <M-H> its there logo.

That old square link chain is called steel detachable chain. You can get info by googling. My old Minneapolis Moline P3-6 grain drill uses the smallest size SDC, which is #25. You can get replacement chain from AgriSupply.

It's pretty easy to open and close the links (hence the name). Here's I TBN thread I started a while ago that shows how to open the links. To close the links, you line up the sides of one of the links with the slot in the other link and use a pair of channel lock pliers to snap them together.

Good luck.

I was sitting on my bench/rake tonight and spotted a logo of some sort on one of the yokes but too small and rusty to recognize, will have to go back up there later with a flashlight and my eyeglasses and try to make it out. Most all the parts are stamped with similar part numbers; H133 for example. Seems to be recurring theme on this rake, an alpha follwed by 3 digits, most if not all start with "H".

You can take a wire brush to it or put some oil or any wet liquid on a rag a lighty skim over the tops of the logo to wetten them to make them readable.
