Hi guys & gals,

I’m trying to install a replacement drive belt on my DeWalt DW735 planer.

I’ve tried to turn the belt on with a 23 mm socket…to no avail. I’ve even heated the belt with an electricians heat gun…still can’t seem to get it on.

I also removed the 23 mm nut and drive wheel…and still not possible to get it on.

Hoping someone can give me some good advice to do it myself.

Thanks to all the guys and gals here on Lumber Jocks !!

Is the difficulty in getting access to the pulleys or is a size or fit issue?

This procedure requires a special tool. Dewalt says to go to authorized service person. So good luck.

I did not use any special tool. What I did do was clear off the bench of all tools etc….and clamped 2 sides of the bench with heavy duty wood clamps, then moved the planer against the corners where the clamps were.
Starting with the belt on the smaller gear…and putting my shoulder into it….I was able to turn the belt slowly and applied continuous pressure and the belt slowly went on the lower large pulley. Voila…that was it…just muscle is all one needs to get it on. Just don’t give up and follow my advice and you’ll also get it on ok.

This guy was changing to a Byrd Head… but at the 20 minute mark – he shows how he put the belt on. He put it on the pulley first, then installed teh pulley

The belt broke on my Dewalt 735. I could not find any good instructions on how to change it except for this post and another on a different board. I finally got around to doing it and I found what I thought was a very easy way to do it, so I thought I would post it and maybe help the next guy.

First part is just like changing blades, remove the top and the dust shoot. Then remove the thickness adjusting wheel and then the cover behind it. Inside the planner on the opposite side of the belt there is a safety switch, it looks like an L bracket with slotted holes, cut a 2 inch block of wood to hold it up so the blades can turn.

Then I removed the chain, one screw on each sprocket, then I removed the chain tensioner, one screw. Then I removed the small access cover over the small pulley, just turn the screw quarter turn and remove.

Now the new part. Put the belt over the small pulley, and then got the belt started on the bottom of the big pulley. Then I took my mini needled nosed vice grips and pinched the belt to the pulley, not hard, I did not want to damage the belt. Then I took a socket and turned the nut at the center of the pulley and the belt went right on. Easy Peazy. Of course it was not completely on I just put some inward pressure on the belt in front of the pulley and kept turning the nut and it worked its way on. I then noticed that it was hanging off the small pulley a little bit. Same thing, some inward pressure in front of the small pulley and keep turning the socket. Reverse the steps and put it back together.

I hope this helps, knowing what I know now the whole job won’t take 15 minutes next time.
If this is the “specialized tool” that the authorized service centers use, I got mine at Harbor Freight. Two pair for $5.
