Mike,
The old single-post jacks are something to be wary off. Make sure the head-unit is in perfect working order. Make sure your jack-points are in REALLY good shape.
Some reporting using it with the door open to avoid the common ding of the door when it slides inward. Carry a board to place under the small foot.
Better off buying a small scissor-jack, save the single post jack for presentation.

I doubt that there are any repair parts readily for these jacks. They were really pretty crappy as far as quality goes and I really believe that one could make a replacement from scratch that would be of better quality, but why would they? Personally I've had more issues with crappy screw jacks than the factory King Dick style jacks. A small hydraulic floor jack and a piece of 2X10 lumber to fit would be my preference as a replacement

Thanks Clay, I was thinking as more of a display piece for my shop. The advantage to buying an MGB is I know have an 8x10 area in the back of my garage. My garage is a car and a half deep. I am going to set up a TV , couch, racing memorabilia . I am a Formula 1 fanatic and ai have boxes and boxes of memorabilia from the past 20 years that ?I now want to display . I also want to buy some MG fun stuff to display . I just figured if ?I was going to strip and paint the Jack, I might as well get it back to working condition.

Mike,
I restored one, but I did not take it apart, since it was in good working condition. As someone already mentioned, my jack is strictly for show. As soon as I can get connected to my external HD (by Friday), I'll send some 'after' pictures.

I had a problem with one factory jack many years ago: the gear on the shaft where you turn the handle on was no longer gripping the other gear that turns the coarsely threaded vertical shaft, for lifting the arm to be fitted in the car's pipe support. I put a hacksaw to the top cover plate and bent it open to both sides.
After wriggling a made to measure and cut open washer underneath the "other" gear (hope this makes sense ), both gears were back in contact.
Now a number of years later I do not use any of my factory made jacks: much to dangerous to my liking

In reply to # 3270483 by Mike-CT-CO.
Has anybody rebuilt a factory Jack? I found one in the " box O' parts". I like tinkering with things like this. Just curious if anybody has opened one up.
I rebuilt mine and it works fine, at least on level concrete.
- Cut the gearbox cover welds with a slitting disc on a die grinder.
- Removed the crank.
- Removed the wood crank knob.
- Removed the gears and screw shaft.
- Removed the rust, crud, and paint from everything.
- Replaced the gear shims (brass)
- Greased the gears with wheel bearing grease, Sta-Lube blue boat trailer.
- Reinforced the foot to upright welds.
- Welded the gearbox cover back on, and smoothed the welds.
- Painted the black & the closest orange I could find and clear coated, and refinished the sanded wood crank knob with gloss clear polyurethane.
- Greased the screw shaft & stub threads.
- Reassembled.
- Had a new black vinyl jack bag made by a shoemaker.
- Put the finished jack into the bag where no one can see it.
- I also carry a scissor jack which is actually used to lift the car.
Be safe out there.
Kenny

Nice job Kenny.
FWIW many years ago, on another LBC, the jack didn't have that gearbox. The handle was fixed directly to the screw shaft. You had to open the door to crank it, otherwise the handle hit the door.

Mike,
Here are a couple of "after" pictures. The arm in these pictures was not painted at the time I took the pictures, but it is now black. I tried HD and Lowes and all the local auto parts stores for the right red, but no one had anything close. I went into Sherwin Williams to have a pint or quart matched to the original King Dick red, but as I was waiting to get waited on, I was looking at the spray paint display and found a rattle can of red that was almost a perfect match, so that's what I used.
