Where are airlift Doors Zerk Fittings?

[cityview]

My airlift door is hanging up. Its only 2 years old. I know they are common in car wash auto bays.

IT squeals like a piggy, but works 9/10 times. Thought It may be a lubrication issue. I read the manual and it says to lubricate all the zerk fittings quarterly. Great. I looked all over the motor and see none, and don't see any others.

I googled to motor model and I can find no exact info about the model (its a leeson), but I see no lube points on the motor and the closest match I can find is a sealed model with non-serviceable bearings.

Where the heck do you lubricate airlift doors? The manual doesn't state, it just says to "lubricate all zerk fittings" (of which I see none), and the motor doesn't appear to have any unless I'm blind as a bat (been known to happen)

Thanks much!

They're on the shaft mounted above the door on the wall. At least that's how mine are.

Squeal could be the motor. They don't last long, I've went through probably 5 of them in a few years. Do yourself a favor and look at a clearview door from gallop next time around instead of airlift. I'm much much happier with my two gallop doors than my 4 airlift doors.

Thats what it looks like it is... Costs almost a grand to replace them to. If I have to do this every 2 years on all 4 doors, I'm going to be over it pretty quickly... haha.

I'm going to be moving some more carwashes as soon as the economy shifts a bit downward, so I'll keep gallop in mind as I build them out.
