I have had to replace 2 sprockets and 1 chain now. I keep my cut to less than a 1/16. Last night, the sprocket and chain went.
They are both the original OEM parts. I am running 12 boards, 7-12" width and 8feet long. Cutting at 1/16 or less.
Is there anything I might be missing like a bad bearing causing the gears/sprockets to be frozen? I did notice the "black feed roller #96", the exit side does not turn easy but I am not sure if that is tied into a gear inside?
Well after spending 6hrs disassembling the machine, here is what I found.
Dust, debris, etc. will bind up the feed rollers enough to make them seize.
Raise the head to highest setting.
Take off cover plates that expose sprockets and chains.
Underneath where the cutter head is, remove screws that hold in both black feed rollers.
The rear roller, you need to remove one sprocket, on the left side, looking at it front the front.
When removing the phillips black screws, the roller assembly will lower and out.
Cleaning..
There is a metal block, felt washer attached to each side. Be surprised how stiff/lock this can be. I took apart, clean and re lube. It's a friction roller and to me a poor design.
put back.
Make sure the little slot on the metal block is facing down. Take notice when removing!!!!
My rollers where so bound up, it broke sprockets and chains...
Again, just take a look at how the roller is mounting, especially the little block before unscrewing.

Chain Question by Glenn
The chain came off after turning the wheel to adjust the depth of the planer. It was turning really hard prior to it coming off.
I was having the same problem when I noticed one of the threaded posts that the sprockets are on was turning with the sprocket. It totally wacked that one corner. I adjusted the post(it has flats spots on the bottom enabling the use of an adjustable wrench), then tightened the screw underneath. Raises and lowers much better. B&D should have designed it with teeth on the bottom of those posts so they won't turn after being tightened. I still have to replace both bearings in the motor (totally trashed), replace fan shroud, and a few other things...then should be like new.
planer motor slow down Question by larry r. burke
Planer motor got hot. Brushes arching more than normal. Smoked some and speed is reduced. Will new brushes likely fix this or will I need a new armature as well?
It sounds like the armature and possibly the field have been damaged. The arching you saw is caused by the bad armature. The smoke comes from the epoxy insulation on either the armature or field melting and burning off. You will need to inspect the field, looking for signs of heat damage. Also take a look at the plastic housings. They can sometimes melt when the motor is overheated. The armature is part #5140011-80, the field is part #5140011-78 and the motor brushes are part #5140011-85.
This is usually caused by the lifting screws being caked by sawdust. You will need to clean the screws. Once cleaned protect them and lubricate them with paste wax. The same type you would use on furniture. Saw dust won't stick to the wax once it dries.
I hope this helps!

Review by troutman
The dw735 is the best semi-portable planer I have found. There are a few design flaws though. The worsst thing about the 735 is the fan shroud design. very deficient thin plastic, and the exhaust fan eventually throws enough wood chips at the shroud to wear through the super thin plastic and then dust & chips fill the inside of machine binding the height adjustment system causing even more problems. I have two 735`s, and have gone through 4 sets of shrouds. Also difficult to keep the planer head, and complete top of machine, parrallel with the table. The service center had no idea how to make this adjustment, there is nothing in manual, we had to figure out on our own. one side could be off by as much as 15/1000 to the other.
Would you mind sharing how you made the adjustment?
Review by Lloyd
I have owned one of these planers for a year now and have been very happy with it. The two speeds make the finishing cuts near flawless with little or no need for sanding ( a matter of preference) as far as dimentioning it is fast and very accurate, having the preset thicknesses makes cutting multiple pieces very simple and fast. Having found an imbeded piece of steel or nail in a board recently and nicking the blades on one side of the planer I found the one drawback for this planer and that is the availabilaty of replacement blades for it and the cost of them. Otherwise I rate this planer as the best for the price and size of it.
On my two month old reconditioned DeWalt planer, the DW735, the feed rate switch is stuck in rate 2. I've swtich gear before while the unit was running as recommended, and it worked fine. I tried again yesterday and it will go to the neutral position where it is between gears and feed roller is not moving, and it will go back to 2 okay, but just will not switch to feed rate 1. Any ideas?:confused:...

Hey all,
I have a DeWalt 735 Planer and used it on and off for the past 2 1/2 years - EXCELLENT planer for the money. Have had no problems at all until...I enlisted the help of a couple friends (with no experience at all - my bad; I know, and have already slapped myself silly like I deserved) to keep feeding - and unloading - a stack of 6" wide cypress boards while I took care of some other important business for a few minutes. One of the boards was longer than the outfeed side of the shop, and neither of them thought to angle the planer towards the corner. The bottom line is the board got stuck; the guy on the outfeed side tried lifting the end over his head (to gain length) and wiggled it some - all to no avail - so the other guy turned the machine off. I ran back in when I heard the planer stop, but by then they had angled the machine and yanked the last 3" of the board out. After a cursory check I turned it back on and tried feeding another piece but no luck: the motor ran but the board wouldn't feed, so I turned it back off. We took the side off and found the belt had worn through and was broken. Now we come to the question I have.
