Although I’ve only been through a set and a half of blades I think my dewalt 734 planer is starting to sound a little on the rough side when started up and thought maybe it is time for a good overhaul since I’m not exactly nice to it. Lots of pallet wood, plenty of rough cut lumber, and a decent quantity of purpleheart and padauk. Only downside is the owner’s manual says to just drop it at a service center once a year for a tune up. There is multiple problems with this
They’re a good distance away, about 50 miles or so
They don’t give a real estimate and I hate bills that are a surprise.
I really like doing this kind of thing myself- this last one is the big issue.

So does anyone know where there might be a parts schematic and repair guide before I rip into it? Mostly think I might need new bearings for the cutter head and possibly new rollers since they don’t grip well anymore.

While I am no expert, just changing the blades will reduce a lot of the noise. Clean the rollers, clean/wax the beds. Vac/blow out all the debris, then see where you are at. Maybe just some simple stuff like that will help.

I would take a look at the motor brushes too. My 734 is still on the original set of blades, but I’m not a heavy user. Thinking about getting the HSS blades vs Dewalt blades.

They can’t give you an estimate at the service center?

If you do figure out what kind of maintenance it needs and how to do it, please let me know. I have the same planer and mine is going to need some sort of tune up soon. I don’t care if bearings are sealed or not. Every machine needs maintenance periodically.

Shane, I’ve done all that, just sounds like there is possibly some dust in the internals and that maybe the cutterhead bearings are starting to go. Just would be nice to have bearings in hand before opening it up.

Go to Dewalt.com and do a search for DW734 . You should be able to download a parts breakdown and use it as a guide to open it up and give it a good cleaning. Lay the parts out (in order) on a separate table or piece of cardboard.
Vacuum and blow out every bit of dirt and clean anything you can get your hand on with a rag and some cleaner.
Remember to wax the table good and if you’ve never done it, consider new blades. They’ll make a big difference

I’ve found it very useful to take picture as I go to. Its nice to be able to see how it came apart.
