What is the purpose of the loop of tubing? Is this to provide expansion
for bubbles that might be present?

Hi Vance,
I’ve always filled the motors with light oil and forgot about them. I
just drill/ tap the motor housing for a pair of small barb fittings
and connect them with a loop of clear tubing (make sure you get tube
that stays flexible in cold water). The oil with travel through
stranded wire so you’ll also have to strip the insulation back on a
small spot, solder a small area and then pot the wire with a urethane
or epoxy compound. As for the oil, WD-40 works great- It displaces
water and won’t attack electric insulation or rubber seals. There’s
always talk on the internet about fear of metal shavings getting in
the oil but as far as I can see you just get a little suspended carbon
and it doesn’t seem to have any effect on how the motors run.
