Hello my Venture 36" actuator is starting to turn slow when it has a heavy load on it, I have tried a couple of different IRD's and it is the same..
I am thinking the motor in the actuator is getting weak... My question is how hard is it to replace a Venture 36" actuator motor?
 
Probably not a bad motor if still running. The jack may need lubing and/or cleaning. One thing to try might be to pull the motor off the jack and see how it runs on its own, vs. when driving the jack.

It has the factory boot on it... it only operates slow when a load in on the actuator, like coming up from lower satellites to the higher ones... it is NOT MAKING any noise and it about 10 year old...To me all signs point to a weak motor..going down hill it moves fine only up hill
 
Have the skills to remove the motor and tear it down?
They ain't too hard to do. Makes for a good time to check if the actuator tube is gooked up.
Weak could be that the brushes are toast, armature bearings are dry and the commutator needs a good Scotchbriting and the gearbox grease cleaned and repacked. I have a superrap-jack on it's 10th life.

Ok

I never repaired actuators as a dealer. They were throwaway, regardless of what went bad. I was just always trying to find the best I could to replace with for longevity & durability, and none were perfect. On some of the Superjacks the rubber wiper seal where the tube runs in & out would go bad in the sun in 1 year and then water went down them and washed out grease & caused corrosion and tube looseness.
 
I asked has anyone never just replaced the motor, I got every answer but that..... But on the other hand I did do what someone asked and I went out there and remove the boot on it and greased it up real good hopefully that will fix the problem...

Well here's your answer. Yeah. I've done it more than once. Getting a new motor is not as simple as removing the old and slapping on the new. Do you realize that?
You would most likely want to put your dish at it's lowest position where the lower limit switch trips.
Then compare the replacement and verify that the switches in it are adjusted the same.
Hopefully it would come with an instruction sheet showing you how to adjust both lower and upper limits.
Set them identically to the old motor. It might even be a situation where you would need to drive the motor/gearbox to it's lower limit manually.
A 12 volt battery, car battery charger, even a cordless power tool battery with wires hooked to it can be used to run it.
Hook it up so that it turns in the right direction until the lower limit switch trips and it shuts off.
The rest.....you've already gotten your feet wet doing that.
...me and my answer but
