Alright guys, I have finally finished painting and started reconstruction. I got everything but the wheels and engine on but I'm having trouble with the clutch. When I put the clutch in the disengage position and spin the big fly wheel the hubs keep moving. How do I fix this or adjust it? Thanks!image.jpg

I assume you have the ball lock clutch. On the other plate we all find a set screw, that needs to be removed first, then the outer plate screws off the nut on the shaft. It probably has years of crud in the threads, the nut will have 6 flat spots on it. Some place on the web is a file that shows how to do this. I'll look for it.

just by looking at the picture you will always have troubles, as you dont have the correct parts in the linkage.

http://amigatec.net/.../David_Bradley/  go to this site, read the manual, follow the steps, make sure you have all the parts listed.

 

You are working with a single disc ball locking clutch, if it sticks you wont be able to stop the tractors motion and it may just run you down.

I will take some pictures of mine tonight. The spring should screw through the arm on the clutch. The only real adjustment is the outer plate on the clutch. Most people either love or hate the DB clutch, I've never had any real problem with them.

Here is the page on how they work.

 

http://www.geocities.../ballclutch.htm

 

Here is how to unstick one.

 

http://www.geocities...tchoverhaul.htm

 

Here are the pictures of the ball lock clutch.

 

Notice the spring, and there are 2 holes for setscrews, you will have one with a screw in it.

 

Also notice how the nut is 6 sided.

 

If you take the inner plate out, be very careful, behind are little balls that are very easy to lose. Mine only had 9, but some 11 or 12.

When you have the outer plate adjusted so the clutch works properly do Not run the set screw down onto the threads....

the set screw must tighten down on one of the flat spots.

Ok, what is the most efficient Rust removal I could get for this project?

Check out this thread for penetrating oil.  There are other good thread in that forum for rust removal also.
