Aquabot turbo classic - pump motor oil

[ooo]

Hey all,

The other day I threw my aquabot turbo classic (unsure of year, 2011-current is what is on their part breakdown) and I noticed it was bubbling up some oil. It didn't look like motor oil, more like a mineral oil. Anyway, I pulled the pump motor out and noticed theres a top plug missing and I cannot find any information around the part number or what type of oil to replace it with.

A bit of background here - I left the bot on the side of the pool during a heatwave (110+ deg temps for a few days) so I'm guessing that lead to the pump motor overheating and popping the bung. The pump itself spins fine, definitely not seized up. I should just need to replace the oil and plug and be good to go. If I'm looking at spending $200 for a new pump I'm just going to invest in a new bot.

Any help here or links would be greatly appreciated - I cannot find anything on google around this, just replacement pump parts.

Pump part #: A6005

(For anyone in the future who might be in a similar situation)

After reaching out to a few servicing places - it looks like once that plug is out the motor is done and needs to be replaced.

What is the plug intended to do?

A motor is (at it's basics) just windings and magnets. Why make a motor that needs a plug to seal in lubrication in the first place? No one is going to re-lube it.

Motors like this that go under water are sometimes filled with a dielectric mineral oil that helps transfer heat from the motor to the water.

Many submersible pumps are also filled with oil.

The oil can be replaced but it's usually a life of motor product.

Right. I'm questioning the plug, that clearly is displaced and lost amongst the plumbing.

Bad motor design, imo.

You might try to refill with mineral oil and seal the hole with hot melt glue. You have nothing to lose...

It has to be the correct oil. It has to be non-conductive.

The plug makes some sense because you might need to service the motor, but it should be more secure so that it doesn't just pop out.

Mineral oil is a thin hydrocarbon oil that is non-conductive. Lacking an oil specification, it is probably a good substitute.

I researched more on the web and found out that compressor oil is a good replacement oil. If all else fails, mineral oil will work. Just make sure to clean up any residual oil or it makes a slick on the pool surface.
