Hi, all new here, glad I found the site.

 

I'm on my fourth DB restoration it's a 7560. I'm trying to remove the clutch but it seems impossible to turn it off of the threaded collar. I have tried using a bar in the hole in the back to hold it and a pipe wrench in front to turn it, to no avail. Never had this problem before. Any suggestings?

 

Another question, I need to replace the engine on two of them. What make will fit the DB while still having the hood fit?

 

Thanks to all.

Welcome to GTT. Try soaking the threads with PB Blaster for a few days. You can homemake a penetrating oil, see the instructions on the home page. After soaking, try loosening. If that doesn't work try tightening and then loosening. I've had to soak some  bolts for months but it beat breaking it. Post some pics for others to see the problem. Good Luck, Rick

Make certain you have the set screw(s) out.  I had a clutch hub that had TWO set screws

one on top of the other.  Then soak with penetrating oil as suggested above.   Light taps with

a hammer some times help break the rust bond.

Don't get the oil on the clutch facings.

 

Once you get a little movement , just keep working it back and forth.  Patience, don't force it.

If I did it right you will see a picture of the clutch. It's on it's side so the penatration oil will soak in. The problem was the clutch facings are stuck to the pulley. Also there is a  picture of my three the Super 3 is waiting for the motor to be repaired. It's a Continental AU85. It won't fire and is also in need of a replacement cap for the govener.

I had one on a 575144 that was stuck, but it had 2 holes drilled in the nut. I made a wrench and used a pipe wrench to remove it. It took a while.

I go out in a bit and take pictures of the wrench I made.

Here is the wrench I made. A piece of flat metal with a couple of bolts in it. Used it to hold the nut, and used a pipe wrench on the pulley.
This tractor had the reverse pulley on it, I removed it so I can add reverse to my 57560. I almost have all the reverse parts for it.
Sorry the last picture is upside down.

I know you are still working on taking it apart...but once you get to the re-assembly process,

be sure to only screw the setscrew down on the FLAT , not the threads.  As you adjust the

clutch, you may have to move the setscrew to the other hole to be certain it tightens against

the flat part.

Thanks guys, and nice wrench idea. I wish mine had the holes also. But, as luck would have it, I never did get the clutch off but the it did become unstuck from the pulley on both sides. It works great now that it all turns free. This DB is up and running.

You could always drill a couple of small holes in it, and then make a matching wrench.
