Two of the three holes for the dust shroud hold down screws broke so I replaced the dust shroud with a new one from a Dewalt store nearby. Once I replaced the shroud I started getting dust buildup inside the casing which jammed the gears that raise and lower the planer head.
I have a dust collection system with 4” pipping so I don’t think that’s the problem.

I never had this problem with the old one. I did notice on the new one the opening that fits over the blades is very narrow and does not go across the full blade opening. Unfortunately I did not save the old one to compare the opening size and cannot get a picture to see if the opening should be bigger.

Any help is appreciated.

I’ve still have the original hood for my 735 and it started doing the same thing your replacement hood does. It lets a lot of chips get into the main cavity of the planer and it binds up the height gearing system. I use a 2400CFM Delta DC on 6” main pipe and 4” drop pipes – so like you, I don’t think that is the problem….. The DC pulls the chips faster then the planer can blow the chips out.

I haven’t been able to figure out where the chips/dust is getting out from under the hood…. The hold down screws are just fine and there are no cracks in the hood. Not sure what is going on. It is not my primary planer so I haven’t taken the time to really investigate the problem.

I have had this same problem with my 735 planer. Mine was caused by a hole in the discharge fan housing. I replaced it and the problem has about disappeared. ( Still get a very little sawdust where it should not be but not a problem) I must have broken the housing when the discharge fan tried to chew up a loose knot or two. Take the housing apart and inspect for a hole. Mine was well hidden… on the bottom. Oh yes… mine is hooked up to a dust collection system also.
