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?
