Front jacks blowing the fuse

[BB_TX]

First time problem. At one park I blew 2 fuses before I got the front high enough to hitch up. Next park blew one. But next park was OK. But at the last one I did raise it a little, stop, raise a little, stop, and then finish. Has never happened before. (except the one time I forgot to loosen the T handles on the JT stabilizers )
Are the jacks supposed to need lubrication? Could not see any zerks to grease them. Nothing looks wrong. Checked the screw on the shaft some have mentioned before, but it was not sticking out any further than normal.

Here's a link to an old posting by John telling you how to lube them: http://www.montanaowners.com/forums/...ad.php?t=39208

Thanks, Dick. That is just the info I needed.

Bill-- once you lube the gears and the screw and if it keeps blowing the fuse or breaker, you may have a bent shaft and that means replacement. There have been several post on this problem(mine included) and that is an easy job if you can get the unit supported on the TV or on blocks. IF you do need new legs my suggestion would be to also get a new gear box assembly too. The newer ones are with a metal housing where the older ones are enclosed in a plastic housing. The motor may be starting to go also IF you forgot to loosen the JTs and put a bind on the motor also. My suggestion is also to put a larger breaker/fuse setup on the line to the motor. I've changed mine out and it works great now. It should since I had to replace both legs and the gear box.

Thanks, Ron. I will try the lube first and hope that takes care of it. If not, then I will move to the next step.
It was 3 yrs ago when I forgot to loosen the JTs, and they have worked fine since then so I don't think that harmed anything.

An easy way to lube the entire screw is to remove the metal plate at the top of the leg and put a squirt of heavy weight gear oil in the top. It will slowly dribble down and lube the screw. It remarkably took the strain off the motor.
