Was beating around the Internet trying to find information on fixing my Dewalt 735 planer. Lots of great knowledge here and some great people who don’t mind sharing with others. Just had to join up.
My problem with the 735? It’s the rollers. The moment any kind of stock touches them, they stop turning and will not feed the workpiece through, no matter how hard I push (within reason). I’ve taken off the side panels and have changed the belt, so I can see that the belt is turning fine. The chains work properly as well, until the work piece touches the rear roller, then they stop dead. Also, I note that the speed lever at the back of the machine has intermittent problems; sometimes I can switch easily between the two settings, other times it will not move no matter how hard I reef on it (with the machine on). Yes, I’ve done all the usual—waxed up the base and cleaned up the rollers and have changed the blades.
Anybody else ever have this problem? What’s been your experience and, short of taking the whole thing to a Dewalt shop, how did you fix it? What’s wrong with the machine? Would appreciate any and all feedback.

I had this problem a while ago and ended up cleaning up the rollers with some denatured alcohol.

Are the knives sharp?sometimes dull blades make it look like there’s a problem with the rollers,try a new set of blades and see if you notice a difference.

So just to be clear, the rollers stop rolling? Or they just don’t grab the wood?

Thanks all for your feedback. Just to be clear: the rollers were cleaned with isopropyl alcohol, the bed was meticulously waxed, the blades are brand new and the belt for the drive has been replaced.
With the side covers removed, I can monitor the belt and the chain drive. When the work piece is pushed to engage with the rollers, they do not slip in the least, they simply stop turning (the chain drive also stops, while the belt drive continues running). The test piece is about an inch thick and the blades are set to barely kiss the workpiece. When I use a thinner workpiece, I can push it under the stationary roller, engage it with the blades, but when it reaches the second roller, the effort for pushing the piece forward simply becomes too great.
I find it real curious that the chain drive stops dead while the shaft and belt continue to run. Any ideas on that?

Short of pulling my 735 apart to see how it works, i’d say it sounds like a drive gear has become loose and is spinning on a drive shaft when under load.

Check for a loose set screw or missing key on the chain sprocket and shaft.

I took a look at my 735 and I’d say if the large belt pulley is not slipping on the shaft then there is a problem in the transmission if the chain drives stops and the belt driven cutter/shaft continues to turn. The cutter/shaft that the large belt pulley turns goes into the transmission box on the opposite side which in turn operates the rollers. Could be a loose gear in the trans. See diagram…..

Loose set screw or something I bet.

Thanks to all for your help. It’s a baffling situation and I spoke several times to the good people at Dewalt’s repair line. Young man name of Forest was very attentive in trying to find a solution, to the point of working on one of their machines to replicate the problem. Even called me back twice to offer additional advice. Unfortunately, short of having my planer in front of him, we couldn’t isolate the cause. Nevertheless, for his dedication, his patience and his determination to help me out, I would say that Forest should be nominated for sainthood. In a truely perfect world, every help line would be staffed by guys like him.

Upshot is that, like “WhyMe,” we arrived at the conclusion that the problem somehow resided in the gear box. Forest recommended that I lug the 92 pound machine to the nearest repair center and get them to look at it. However, before I do that, I’ll take another gander into the gear box, like “johnstoneb” suggested, to make sure that there isn’t a loose gear or missing/worn key on the shaft. It would make perfect sense. Will keep you posted on my observations in the hopes that, somewhere along the line, someone here on this forum will benefit from the experience.

Finally, closure on the problem. Took the DeWalt 735 to the repair shop and it turns out the problem was indeed a broken key as some of you suggested. This one was on the sprocket that sits on the shaft which comes out of the gear box to drive the rollers. Roger at the DeWalt shop in Burnaby (Greater Vancouver area, British Columbia) had the problem aced within five minutes. The sprockets were five dollars and change each, I bought two and took the machine home. Once the new sprocket was installed, the machine fairly hummed. Thanks to all who responded to my plea for help, as well as to Forest at the DeWalt repair line as well as to Roger at the Burnaby repair shop.
