Nutone 398 Power Head Replacement
I have a nutone 350 central vac with 398 power head. The belt drive on the power head doesn't seem to line up quite right, resulting in either belt running off or eventually coming apart. I've tried to shim the motor, but it still doesn't set quit square with the brush. Is it fixable or if it needs to be replaced, what is recommended? Lot of carpet in house. 398 has about 4ft, 2 pin cord coming out of powerhead that clips to metal wand. Ben, B.C.
