Electro hydraulic center stand motor
I am on my third center stand actuator, fortunately all under warranty. Below info may prevent a failure and is so easy to do. This does NOT deal with the hydraulic pump, just the motor.
I just had mine replaced and kept the old one.
I took it apart, mild corrosion BUT the brush GROUNDING screw used in the motor is fine threaded steel, the housing it screws to is pot-metal aluminum. The screw actually loosened itself!
Perfect combination for galvanic corrosion, steel, aluminum, electrical, & moisture!
Took the screw out and replaced with a stainless steel screw and washers and a touch of never seize.
Took my NEW motor off .
Very easy to do, disconnect 1 molex plug, 2 #5 allen bolts and did the same as above.
Do not pull the rotor and spline through the front brush end of the motor, just take the case off while holding the spline end with soft jaw vise-grips (the magnets want to keep the rotor with the case housing when you start to pull it off).
I unscrewed the brush grounding screw & washers and replaced with stainless steel.
The second screw just holds the plastic brush retainer in place.
I lubricated up the rubber seals and o ring (be sure to place o ring on motor assembly first) and re-assembled.
The assembly as designed should NOT get water in it, BUT moisture wicks through the flimsy flat gasket, I saw the trail in the housing.
Waterproof grease or thin coat of RTV should stop the moisture intrusion.
I am confident it last MUCH longer now!
Hope this helps someone from an expensive repair!
