Topic tags/keywords: planer dw733 pulley belt disassembly question trick tip

I’m new to this forum, and noticed a whole lot of discussions on the dw733, but no answer to my problem. I would greatly appreciate anyone’s input on this.

Yesterday while planing a piece of oak I heard a rattling sound, and before I could turn it off it was obvious the motor was spinning but the blades were not. The roller blades still work and it ejected the piece. After taking the side cover off I found that the belt was partly melted, the pulley on the cutter head was not bolted down, and there was evidence of metal shaving. Upon closer inspection the pulley is a little bent, where there was a tiny little piece of metal I found out was called a key. This was lying at the bottom of the planer. The bolt that holds on the pulley I can’t find anywhere…

So, it seems the bolt came loose, the tension from the belt yanked the pulley out of allignment, ejecting the key and bending the slot it sits in in the pulley , the belt rubbed against something stationary at velocity and melted the edge off. All this without visibly damaging the cutter head, blowing the motor or hitting a knife!!! Whew.

I looked up all the parts and can get everything near there, including the belt, for about $60. So now it looks like this is something I can tackle, but the dang pulley can’t disengage from the cutter head as it is blocked by the threaded height rod! Did they do this on purpose?! I can’t replace the pulley without disassembling the entire machine, it appears. I’m concerned that once I start breaking this thing down I’ll never get it put back together in perfect allignment, and a planer that isn’t perfectly alligned is a really expensive paperweight!

Has anyone ever tackled this job or anything like it to where they had to disassemble the planer, and were you successful? Any tips, tricks or warnings?

Thanks!!!

I’ve fiddled a little with my 733, I say go for it…its a paperweight right now so you’ve got nothing to lose. The little I’ve done with mine (re-aligning the heads back to parallel) convinced me that the manual and parts list and exploded diagrams were sufficient to go further if I had needed to.

If somebody can put it together ,you can take it apart and reassemble it. If you have a manual you’re almost home free. Sounds to me like you are mechanically inclined enough that you can make it work. Go for it.

Thanks both of you for nudging me along! it wasn’t too big of a deal to get that threaded height rod out of the way, just had to detach the chain under the unit, brace the unit, and twist it out. I’m just waiting for the parts to come in the mail now..
The disruption to my project prompted me to allign and wax my joiner, sharpen a few blades, allign my table saw trade a blade out on my bandsaw, and come up with more projects for myself! Oh the joys of cabinetry, turns out you have to be a mechanic too, which was never my favorite thing!

Welcome to LJ Chiroman. I came from a background of mechanics so these things don’t upset me too much.

I’ve taken mine completely apart and put it back together. It’s a lot easier than it looks, if you make notes of which bolts came from where when you do it. ;)

Well the reassembly went fine, got it alligned and it’s running great. Getting that belt on the pulleys is a bear! I figured out in putting it back to gether that by placing two boards of exact same dimension on either side of cutter, turning the threaded height rods by hand until you have the cutter parallel to the bed, you can then tighten down the chain drive underneath the unit, ensuring a level cutter. The manual doesn’t describe making this adjustment, but it’s easy to do, just a couple of set screws holding on the chain pulleys underneath. there’s a dab of thread lock on them that doesn’t seem to be doing it’s job as there was no issue loosening. So if ever you notice your boards coming out uneven, this is how to adjust it.
