Jack mounting plate

Hello All

A couple of things to ask. My electric jack stopped jacking. The motor works fine but it must have lost its grip on the thread as now it neither raises or lowers. I took the jack off to see if it could be fixed and found the mounting to be a 'little' worn (see attached pictures)

It appears to hold the tongue weight of a 31ft 73 soveriegn (600-800lbs) no problem, but seeing this is a concern.

I've searched the forums and found little information about this issue. There is mention of coupler replacement, so replacing the whole thing is an option, but if it's possible to weld some sort of attachment would that work?

I'm also thinking of a replacement electric jack that includes manual operation, any suggestions

Sincerely
Andy

plate...

After you clean up and have cut away the rusted areas, just cut a piece of 1/8" steel plate to fit, then weld it on all sides and grind the welds smooth.

My '73 27' manual jack displays no similar corrosion (whew) after a panic check a minute ago; man-o-man count yourself lucky that didn't punch through, say, trying to lift off your tow rig that just had a flat or breakdown, or other nightmare, say at leaving fully booked campground, etc..

A manual jack mechanism is twenty to fourty spins that seem to go easier the faster it is spun. I lube the mechanism with pintle-hook spray lube from lubri-plate that is gnarliest formulation I've found as it dries rapidly into a damp paste that doesn't attract grit. I remember the mechanical leverage is different on dual-action jacks; probably more turns required on the electric for same lift - that might be a valid sales point...

Coupler

Man are you lucky. From the pictures it looks bad.
The coupler is welded in place, so it can be removed by cutting?grinding through the welds and a new one welded on.
I'vve replaced these on other various trailers that were also welded on.
Recommend two things.
1. Ask other Vintage owners where they got their couplers from and check prices. Your present coupler is probally worn.
2. Have the final welding done by a Certified Welder for two reasons,
A. They know what their doing.
B. They carry insurance to cover mistakes
Ask around your community/town/county. There will be a shop or person that will surface that has been doing that service for years and is reasonable and might iven come to your house to do it for a nominal charge. I know of one of these in my area.

I think it would be a good idea to replace the coupler. It cost me $50 to have a welder come to my home to weld on a new coupler. I had removed the old one before he arrived.
If I hadn't already replaced mine your picture would have sent me out to check it. I'd hate to think what would happen if the jack gave way and the tongue came down on your foot!

Cinder-ella

BTW a cinderblock is NOT a good idea used in the manner shown in your picture. Uneven pressure can cause them to fail catastrophically with no warning what-so-ever. Please, get an automotive jackstand instead. We'll all breath easier

Cinder Block

Missed that.
That tongue could go right through that web any minute.
If you must use cinderblocks then place a 2x8 on top of the cinder block covering all the side that is load bearing (in this case 8x8") to properly spread out the load.
Bdtter yet use two cinderblocks and use a 2x16" board to spread out the load even better.
Best: Jack Stand as previously stated.
I have seen people killed when using cinder blocks without the 2xwhatever to spred out the load evenly on the whole top of the cinter block.

re: cinder block

thanks for the concern guys. that cinderblock/breezeblock is filled with heavy duty concrete. it was from some wide eyed project a while back and just happened to be around. see attachment. i think the load balance is ok, but good call on the automotive jack. i'll be running by the auto store tomorrow.

tonight i ordered a FULTON A-Frame Trailer Coupler, 10k Capacity for $39.95 and will be calling on a local certified welder tomorrow, see how their schedule looks.
thanks for all your help.
i hope my luck will have encouraged those with older trailers to check their own couplers if they havent already done so.

sincerely

I'm glad you had a good, solid reason for using that block.
