Dave. How do I reach you again? I have a couple of guys who'd like to talk to you about those superb pulleys. I'd prefer to have them contact you directly. Can I get your email and telephone number? If you can send me some pics, like those here, and I'll add them to my Facebook and maybe get you some customers.

That puller Robert described will work fine. I'd get real good quality rod to make them out of. I pulled a grade 5 bolt in two with my puller.

I made mine out of heavy bar stock about 3/4 x 3 with heavy pieces across the top to push against, and two more pieces on the bottom with just enough space between them for the axle shaft. Another piece sits on top of that with three holes, two for bolting the 5/8 or 3/4 bolts thru and the other for the jack to push on the axle. I use a 20 ton jack and have had sprockets not want to come off with that, so some beating and heat got them off.

I'll try to put up a picture of mine in action. Used to be one on here, but we lost it in a site crash I believe.

Hi Blake , i left you a message on facebook .

Thanks Ian. I'm gonna switch to a better hosting company very soon, so hopefully it won't be going down as much. The current one has issues.

Snyder's Antique Auto. They have a diagram on their site. They have everything, except for the input shaft and the u-joints.

Good to see the forum Back on line Blake .

There should be two threaded holes in the sprocket hub.  Run a tap in them to clean up the threads. The holes will be 5/8" or 3/4".  Get some threaded rod that size a good stout piece of box tube and a bottle jack.  Drill holes through the tube to match the sprocket.  Screw in two long pieces of threaded rod into sprocket slide the tube over the rods.  Put the jack between the tube and the end of the shaft tighten down two nuts on the threaded rod to hold jack in place.  Pump up the jack to pull sprocket.  It may not come easy!  If the jack will not pull it, put pressure on it with the jack and wack the back of the sprocket with a large hammer. If it does not come you may need to heat the sprocket hub with a torch.  Do not stand in front of it as when it comes free it will jump at you!!

I have a about a 1953 model. has a bad leak on the left rear sprocket.  where can I get a puller?  I"ve got the nut off.  some of you guys have talk about making one what do I need to do that?

Thanks for the update. Am anxious to see progress pics when you get to that point.

Just an update to let interested parties know that this project is still alive, and making some progress.  I have redrawn everything that was lost in the computer crash, plus some new drawings, thanks to some new info from Doug.  A lot of detail remains to be collected and added.  It is really difficult to tell accurately how parts fit together from photographs - mostly by trial and error...many errors...so far.
