DISASSEMBLY INSTRUCTIONS
PLASTEC UTILITY AND STORM BLOWERS
Before beginning these instructions, place this fan on a bench or table top that can
support its weight.
1) Remove Torx head screws from the motor plate. (These screws require a T-20 bit.)
2) Lift the assembly clear of the fan housing. Set the fan housing aside.
3) Use a thin flat head screwdriver to pop the black hub cap off the bushing. It may be
necessary to reach between the blades of the impeller to do this. (Be careful not to
damage the impeller during this step.)
4) Remove the shaft bolt, lock washer and washer. The bolt will be 8mm, 10mm or 13mm.
5) Use a gear puller to remove the impeller from the shaft. Always use the bushing as the
pulling point. Pulling on the blades or rim of the impeller will cause irreparable damage.
6) Use a 10mm or 13mm socket to remove the four bolts securing the motor plate to
the C-face.
