Power Jack Problem

My 1984 Excella 31 rear b/r center bath has the Power Jack installed. It has always worked fine until one of the rampant know-it-alls exceeded the upper-limit of the jack's travel and stripped the little fiber gear inside the main housing. That part is designated "2nd/3rd gear assembly" in the Service Manual. Anybody know where I can get another one in order to repair this problem? I think I can probably replace it myself if I can find the part. The jack is original to this Airstream. Thanks ahead of time for any help. Jason Brooks

Jason, is there a brand name on the jack? If not you can give a call to Airstream and possibly see if they can ID it for you. Maybe there are parts still around.

Are you sure it is stripped?

Mine has an overrun protection built into it - the PO had ran it up to the point of not working (I thought it was stripped) - I removed the power unit, manually screwed the leg down a couple of inches, and the fiber gears meshed once more after I lowered the center jack post. It now operates fine.

One other point, I had a "squirrely ground" problem - solved by installing a battery to frame grounding strap and "polishing" (seating bright metal to bright metal) the compression areas under the three bolts holding the power jack assembly to the tongue.

Need a Jack?

In spirit of sharing, we have Airstream jack removed from 1989 Excella 25, with up/down toggle switch. Was working when removed, but was welded to frame and hitch flange, and PO had pulled forward while jacked, resulting in about 10 degree top to bottom rearward slope to jack shaft... New Atwood unit is vertical, is bolted into flange, and has a light, so I'm happier..

Motor and transmission worked fine, and unit includes manual jack handle... Whilst it might fetch huge $$$ on E-Bay, I'm willing to send it to someone here who needs parts or wants to work on straightening flange... Would ask for only packing and freight charges...

I didn't look for a brand name on the housing. That is a very good idea. I'll check that out tomorrow. Thanks. JAB

Yes, unfortunately, stripped. I took off the little metal bonnet and could see that the brown fiber gear had about an inch of its teeth ground down from the other gear meshing with it. I just have to find one and replace it. Thanks for your reply. JAB

John,
It makes me happy to see that we share on here.
I am glad that you are offering your old jack.
I just bought a "returned" jack from the Camping World outlet in Bowling Green, KY. The original store is used as an outlet center too. All of the returns and clearance items are sent there. I paid $100 for a returned jack. It is a Barker and retails right around $229.
I hope someone can make use of your old jack.

I have replaced several of these gears on my Airstreams over the years. Probably due to my own fault on occasion. They are definitely a week link and now I always keep one on hand. You can get them direct from Barker Manufacturing for about $25. Scroll down to the Super Jack.

You, sir, are a gentlemanly scholar. Thank you very much for your kind information. I ordered one of the gears tonight and happily anticipate its arrival. Hopefully even I can figure out how to install the thing. Thanks again. This is what these forums are so good at. Jason Brooks

No problem. When you loosen the four screws, about 200 springs, washers and various pieces will come flying out of the casing. Simply gather them up and carefully put them back together. Iím Kidding! You won't have any problem installing it. It might be a good time to adjust the limiters too but itís been awhile since I last did mine so I donít have a fresh mental picture. I remember it was simple. Good luck.

Hey, I thought as long as it was no more than 200 I could probably manage it. Thanks again for your advice. I love this forum. Jason Brooks

Why do the little buggers never fail in your driveway?

On my 73 it wasn't stripped the fiber part started slipping on the metal shaft. I lucked out and found an all metal replacement gear.

Power Jack for free + shipping?

Well-

One of our members got a new jack for a present, and another has apparently decided to repair his, so here's the updated offer...


I still have original power jack from our 1988 Excella, including hand crank, boxed and ready to ship, which I'll gladly do in return for payment of packing charges (box + foam + plastic worked out to $19..) plus freight to your location... If this doesn't work, I'll go try e-bay, but I'd rather see it go to forum member first...

As reminder, it works perfectly in terms of up and down, is missing round foot plate, and was bent gently by prior owner so that flange is not perfectly perpendicular with shaft.. Looks like trailer was pulled forward while jack in contact with ground... Has no light, but does have cig plug receptacle added...

Photo's attached.. If interested, send PM or e-mail to get final quote for delivery (from San Franncisco area..) and arrange payment..
