    Pump Overheating?

    K... I know this is for pools but I can't find any information anywhere and a motor is a motor...

    We have an ancient Coleman Hot Tub (guessing 1985ish) and I've been having some issues over the last few years. She's so old that it's entirely run with various relays and no electronic boards. I've always maintained her with new framing, relays, timer, seals, etc. and just don't want to replace her just yet.

    Anyway, when I turn timer to run on high flow, it will soon after start clicking off and on. I think it's the internal motor thermal protection because after about 15-30 seconds or so, she'll start pumping on hight again. The filter is clean along with the pump. She'll even do it without the filter. An online shop told me to buy their Deluxe Rebuild kit for $89 that's basically new bearings. Is there anywhere else to get the bearings cheaper? Could the the bearings be dragging creating that much heat and kicking the thermal? I really don't want to replace the pump since it is still strong and not leaking at all... and I don't have several hundred bucks to spare at the moment.

    Any information would be greatly appreciated.

    Could be an electrical issue aswell. I'm not sure I would spend $89 + tax on a guess.
    Wouldn't it be better to check Craigslist or Offerup for a cheap like new motor?

    Looks like a capacitor housing on top, have you checked it?

    I believe you need a new motor; it looks old and shot. It also looks like some water damage, which usually means it's time to replace

    Yes you can get bearing very inexpensively. I'm not positive, but it looks like you'll need a 6203 and a 6204. (Pump Motor Bearings for Swimming Pool Pumps -
    You can check eBay pricing. You'll want a 6203-2RS and a 6204-2RS (2RS stands for double sealed). You'll also need a new shaft seal.

    Looks like you can get the motor for $200 Magnetek 1 HP 2 Speed 115V Thru-Bolt Motor - BN37V1 -

    I'm in the process of replacing my bearings on a different motor. Good luck.
