Rear stabilizer motor

Our 2011 Montana has the electric motor driven rear stabilizer with two pads that come down to the ground. The assembly is Lippert and the motor is made in India. We recently had the motor refurbished due to internal corrosion. The head of the assembly contains a gear reduction set. During the refurbishing, one of the gears went missing. Oh no!!! I'm trying to locate a replacement gear.

The missing gear slides down onto the small shaft seen in the right side picture and mates with the spline gear on the drive motor.

I will try Lippert as well but they probably want to sell the motor complete. If someone has replaced their motor and may still have the old one, any help would be appreciated.

Thanks

  • Thanks AZ T&T. Never thought to ask them as the fiver is a 2011. I sent their warranty department an email and will let you know their response.

  • I had the same motor go bad on a 2 year old rig. I contacted lipert and they sent me a new motor. All they asked was after receiving the new motor, is that I send them the new motor.

    It might be worth a try. I couldn't believe how much the replacement motors are!!
  • Hi Dave. The moisture likely gets in from road spray while towing in wet weather conditions.

    Removing the motor was a bit of a problem for me as the four small mounting bolts had some corrosion on them. I had to drill out two of them. Once removed there is a rubber casing over the motor housing that I was able to slide off without damaging it. There was some adhesive holding it on. Remove the two end bolts that hold the motor housing together. Then slide the housing off to expose the armature. The moisture was entering where the housing separates. This caused the small springs holding the commutator brushes to rust. One of the springs was dissolved.
    When I refurbished the motor, I sealed it during re-assembly using silicone. You may have to replace the springs and brushes. A local electric motor repair shop had what I needed.

  • DrSmart, if you can tell us where the corrosion issue stems from. If it is like a bad seal, we can caulk it up before it corrodes. :h
  • If you do have to go new, try EBAY, there are a couple of new motors there with the gear reduction for a lot less than what Lippert is asking...
  • Thanks Bill. Great selection of stabilizers too. I'll contact them.

  • Hi ronniedean1234. Yes I have posted on the MOC and tried the dealer where I bought the Montana. The parts department had very little interest in locating a discarded motor. They'd likely be very helpful if I wanted to order a new one. I believe Lippert's price was over $400.
    I might take the motor in to a couple of RV dealers and try to talk to a repair tech. They'd be the ones that would know. The rear stabilizer by Lippert is probably installed on many brands of trailers. The motor corrosion problem is fairly common.

    Glad you were able to help out your relative.
  • A few months ago I repaired a motor on a relatives Montana with a corrosion issue, he was ready to order a new one until I intervened. Im sure someone out there has one thinking that they needed a new assembly rather than look into a repair. If I remember right, you have been looking a awhile for the gear, have you called a dealer that may have one they discarded, good luck in your search...
