Re: Noisy fan on range hood

My 5th wheel vent flap has a locking tab so it doesn't flap when going down the road. I just lock it down on windy days when the range is not in use. I probably will install something on the TC to do the same.465Views0likes0CommentsRe: Happijac motor drive
Hi Dan, I had used the jack two times just a couple weeks before it "stuck" so I thought it couldn't be "seized". I just didn't think it had had enough time for that. I put a rag on the motor output shaft gear and grabbed it with a small pliers. It didn't take much force for it to loosen up. I then hooked up a 12 volt power supply to the motor and ran it a few minutes in each direction. It ran fairly smooth from the beginning and seemed OK. I put everything back together and ran the jack up and down enough to put normal loads on it and again, it ran fine without any unusual noise or vibration. There had to be some moisture down in the motor bottom bearing to cause it to "stick" so I suspect it's just a matter of time. But for now it looks like I am OK.769Views0likes0CommentsRe: Happijac motor drive

If you're handy, you can replace the top and bottom bearing and the whole drive assy is as good as new for less than $10. As soon as these motors give off the sound of nuts in a blender, it's the bearings. An update: The wiring was fine, and I plugged in a drive from a different jack at that location. It ran fine. I decided to take the assembly apart to see just what was wrong. The motor was stuck and wouldn't turn by hand. A good nudge on the output shaft and it started running fine without the "nuts in a blender" noise. I ran it for quite some time forward and reverse. I then put the drive and gears back together. That assembly then was run in both directions and it seems fine. I didn't take the motor apart, but I'll bet the bearings are on their last legs even if they aren't noisy.....yet. I know I am likely on borrowed time, but perhaps not. I'll probably get a spare for "in case". Thanks for all the tips and suggestions. This is a great forum with helpful people!768Views0likes0CommentsRe: Happijac motor drive
Wow, thanks for the replies. It sure sounds like I am not the only one with this issue! I may get a refurbished one, and send mine in for repair to use as a spare. I sure am glad they can be hand cranked. It saved me a lot of grief getting the camper off my hunting grounds and back on the truck at the end of the season. Thanks again guys!326Views0likes0CommentsRe: Happijac motor drive
Thanks for the reminder Artum. I have read through the jack section and there is excellent info there. The one topic not discussed is the drive motor system itself. I suspect all the Happijac motor drives are the same as they appear to be the same from model to model. The ones on my 4150's look and run just like the ones on my 4500. I would just like for someone to confirm.326Views0likes0CommentsHappijac motor drive
I have a Bigfoot with Happijacs. One of them keeps blowing the fuse. The jack moves freely when manually cranking the jack. Do any of you know if all the jacks use the same drive motor assembly? I have 4500 series jacks on mine, and I am looking to replace the bad one. I don't know for sure what the part number would be. I have found 600510. Will that work?9.8KViews0likes23CommentsRe: Will my space heater shut down my furnace?
I like Christopherglenn's idea best. I heat with space heaters and leave the furnace on manual fan only. It will constantly circulate the warm air in your camper and the underbelly. It gives more even heat throughout, and won't result in the furnace "kicking in" making lots of noise in the middle of the night.321Views0likes0Comments
