My 2014 AC Revolution's jacks are powered by an electric motor driving hydraulic fluid. The motor is currently undergoing its second replacement due to rust/wet/corrosion. I replaced it at about 4 years of age and that was 4 years ago. Its toast again.
My question: Has anyone tried sealing up one of these motors with caulk and/or fabricating a gasket for where it sits on the pump?
I'm tempted but don't want to cause overheating or some other unforeseen issue.
Let me tag on a photo to help visualize what I'm talking about.
As you can see or imagine, there are multiple points where moisture could enter the motor: at the base where it attaches to the pump, at the adjustment screws around the body, where the main body meets the silver bit at the top, the smaller metal cap that is screwed on to the top, and the plastic cap at the very top that allows access to the bolt to drive the motor externally.
My guess-timate is that the most likely entry point for moisture is at the base. I'm afraid though that if I just seal that and water gets in another way, it'll be trapped in there or potentially drain through the pump bearing into the reservoir.
Anyway, at this point I'm looking for the wisdom of all and preferably of someone who has sealed the motor and succeeded in preventing recurrent failure due to moisture.
Thanks in advance for all insight provided...
