Barker Jack blowing fuses

[m.hony]

How/where to lube?
I took it all apart before I discovered the blown fuse and it seemed all slippery/greasy in there.
Unrelated question, but grease/lube brought it to the forefront of my mind:
Where/how do I "lubricate gears twice a year" on my Winegard TV antenna?
I don't see any way to do that from inside the trailer.
Looks like I will have to go up on the roof to do that.

. . .

Your owners manual, linked in Post # 27, says:

"1. Every two years remove screws and cover and check grease condition. Use HMP grease similar to lubricate 630AA and spread on gear teeth, Grease is not required on the nylon timing gears. No internal lubrication of the post is required, but an occasional external application of a silicone or WD-40 spray lubricant on the inner tube of the post when extended is permissible."

[p. 48 of the PDF]


Additional instructions go on at that location . . .

How about hitching up to support the trailer and the remove the head if req'd and manually extend and retract the post? If it's bent or damaged the manual operation should let you feel the binding. If binding, requires more current due to heavier load.

I think not bumping hard into the hitch while hooking up is a great to NOT bend the post.

Another cause for blowing the jack fuse...wiring worn thru where it runs under the tank cover...replaced wire and covered with split loom.

It would be great if someone could post video of how to lube the Barker jack.

Ditto for a video showing how to "lube gears twice a year" on the Winegard TV antenna.
I think I got the concept of lubing my Super Jack.

Got my package of (3) 30A 250VAC fuses from Barker today.
Will put them in the trailer-
Heading out on a trip Friday-

I just ordered a new Super Jack by H & H Engineering a division of Barker tongue jack from Barker for $339.
It is $379.99 from Vintage Trailer Supply.
They will send a cover for the jack, too.
The guy told me that Airstream no longer uses Barker jacks, but uses Atwood jacks on all trailers.
I wonder if there is an Atwood jack painted to match the trailer frame.

Just put a new black 3000 pound Barker VIP jack on our trailer, as the original seemed to be leaning a bit. Probably from that time we backed up at Joshua Tree with the jack down. (sigh). Still worked, but groaned a lot and as we raised the trailer on the jack the foot would slide forward more than it should.

We figured out after the fact that the exact match Barker these days is probably the Deluxe High Power 3500. We ordered the 3000 because the Barker jack already on our trailer said it was a 3000. So, if/when we wear out this jack we'll go with the fancier one. Apparently the higher rated jack has a 2.25" post while the 3000 has a 2" post. Fortunately, it mounted nicely anyway and seems to work just fine, as 3000 pounds is 3000 pounds so it's not overloaded.

BTW, the black jack looks just fine, don't care that it's not battleship grey. Oh, and we finally rotated the power head 90 degrees so now we can open the tailgate without issues. That's nice.
