If you read my other thread on sanders, you know I just had to buy a new PC 340 palm sander. The reason for this is my stupidity, and PC's poor assembly design. I'm fairly handy, but this thing had me cussing and squirming for over an hour trying to get the housing back on. In the process I broke wires twice on the brushes, soldered the first back, broke a wire on the switch, fixed it, and finally gave up after the second brush wire.
The problem is that all the "guts" just kind of set there and the two housing halves hold everything together. That's fine, but it's virtually impossible to get the two halves together without something inside shifting. The main problems are the "fan" on the rotor that generates suction and how the brushes are mounted. The brushes just set in an indentation and are not held down by anything or "clicked" in. Then when you try to mount the other housing half you have to force it over the "fan" which levers the rotor up and dislodges the brushes and wiring.
VERY frustrating and poor design if you ask me. It's like they did it on purpose so you'd have to take it in for service just to lube the bearing! Anybody have tips on how to service this thing before my second one needs lubed?
