Tongue Jack won't stay up

To make hooking up the Husky In Line easier and in some cases possible at all, I have been lifting the back of the truck using the tongue jack. This seems to be working ok, but I think I have overloaded some sort of braking system in the jack. It will still lift, but it won't stay up. The problem seems to be getting worse pretty fast.

Is there a friction adjustment that can be made in there?

Seems odd - hopefully someone with more knowledge of the internal workings of these jacks can explain what is happening.

I did not think there was any kind of friction braking system incorporated in these jacks. from my Mech. Eng. days (many years ago!) I thought that the design of the screw in the jack - i.e. pitch of the threads - would determine whether the nut on the screw could run down on its own or not. I think in an application like this, the design of the jack screw should not all ow the jack to run down like this - i.e. for the jack to run down, the screw would have to drive the gear train and motor backwards under gravity and I would not have expected that to be possible.

So I wondered if something in the drive train was broken - but you say the jack continues to operate properly (other than coming down on its own), and that seems hard to understand.

I regularly use mine the way you describe - i.e. I use the jack to raise the trailer and the back of the truck a bit to make it easier to wind up the spring bars on the Hensley hitch with a cordless drill. I've sen doing it for the last five years or so since we got the AS, and so far haven't encountered any issues.

I'll be interested to see what other comments come in! Sorry I can't offer any useful help!

Brian.

There are balls in the tube of the jack that hold the jack in a given position. Not sure how they fail but when they fail the jack will auto drop when there is a load on the jack.

Call the company. They will sell a new jack post or may have a reconditioned post.

Yours is toast

Tongue Jack Clearance Question

There seem to be a lot of these Tongue Jacks out there on the internet in the $150 to $250 range. The one I am replacing does not seem to be out there anywhere, even from the folks that make it. The local RV dealer quoted me $660 which is outrageous.

Has anyone replace their tongue dolly and found they had a clearance problem with the Propane Tank Cover?

I have a 2010 27FB Classic.

Bob from Barker Manufacturing called me back. He recognized the problem right away and is shipping me a new Leg for the unit. It is refreshing to have a company stand behind their product.

Thanks for the info Ricky

New leg came today. Easy change out. I think this problem is behind me at no cost. I like that. If you have to buy a new tongue jack - I would recommend something by H & H engineering.
