Electric jacks: what do I have?

[stevejahr]

Not sure what Forest River used for the electric stabilizer jack motors here...

What I *do* know is: late 2015 (sold as 2016...) Rockwood 2604WS with 25" BAL "C" stabilizer jacks with center extension rail.

Definitely NOT the BAL power module though, mine are inline motors mounted on the inside end of the jack screw.

I have one which seems to have a bad clutch or stripped connection. Motor runs but jack moves with jerks or not at all. Cranks just fine by hand.

Options seem to be to either figure out what I have so I can check into parts or spend even more money to update to the BAL power packs on the outside end of the jack screw.

There are only a couple of brands of power stablizers. UltraFab makes one with 2 motors. Lippert makes one with 1 motor.

Do you have pics of what you currently have?

[stevejahr]

I will have to take pics and probably just pull one out.

Usually you can ask Uncle Google and find *anything*. I have not found these anywhere.

It is a two motor setup and they are definitely BAL type C stabilizer jacks. The motors mount inside the channel of the jack inline with the jack screw and drive the inside end of the jack screw.

The Ultra-Fab Power Twin showed a diagram that matched up for location of the electric motors but their other pictures were not a match.

Not having ever seen one that you're talking about, just a SWAG would be to remove the defective side motor and look for a sheared drive pin.

I am thinking nobody has ever seen these things.

Pulled a motor out. Basic Chinese mfg can motor BRS-775SH inside hooked up to an inline round reduction gearbox. Round motor/gearbox mounted into a plastic block using set screws. Two carriage bolts mount the plastic block to the extension channel of the jacks.

Drive is via inline 3/8 square output from motor connected to D on end of jack screw using a plastic adapter. I suspect there may be a crack in this adapter allowing it to slip/jump on the jack screw. I am going to mark it to see rotation and watch as it operates.

Steve did you ever find the part? I am probably having the same issue. 2016 2702WS with electric jacks. Motor spins but appears the plastic spindle it connects to is stripped.

Works fine with the good ol manual jack wrench.

If it's cost effective and easily replaced I'll just do it myself before I take it to the dealer for a warranty fix.

Here is mine.

Just make one out of tubing/pipe.

That is almost EXACTLY what I have

Yours is slightly different in that it has ribs around the ends of the plastic adapter where mine is flat.

My failure is on a front jack and I have been using in manual mode which really has not been too bad since the fronts go up/down so little (compared to the rear). That extra 5-6" lower makes a big difference. I have had too many other projects on the trailer to get back to this one. When I do my plan is to see if I can mark the motor, coupler, and jack to see if there really is slippage occurring.

As to making one from pipe... this may not be as easy as it sounds. The jack end used a D for drive and the motor end used a square drive.

If it is slipping (or if yours really is just stripped inside) I would not hesitate to get the part from a dealer and replace myself. Really only takes removing two nuts to get the motor out and replace that part. Easy peasy.
