Let me qualify the following by saying individual results may vary and be careful when servicing your PV, turn off power/unplug unit before removing cover!

Yes, one drop each time
Lee1 wrote: I did notice a silicone (thermal) seal at motor to where it bolts up, does this come off easy and does this need to be applied when put back together.
Yes, reseal if needed, use Pro-Seal black or Rutland orange high temp RTV
Lee1 wrote:Also how do you get at the cooling fan to spray wd 40?
Spray up into the fan while turning it by hand or give it a spritz while running after you clean it
Lee1 wrote:And lastly would you pull motor in off season to preserve better.?
Yes, I pulled mine off at the end of the season and put a plate over the hole
Best wishes for long PV life, after following the maint tips perscribed I have over three years on mine and no signs of slowing down.
