I have three rather old Russian screw jacks for my Yak. One works fine but the other two get to a certain height and do not want to move further. I used the bigger hamer principle and put a section of pipe on the handle for leverage. That idea was only partially successful until the lower shim/washer/bearing surface buckled up. I assume these washers/bearings are shot and need replaced as I have throughly greased and oiled the srew as best I can. The design of the jacks look to be a permanently installed jack collar/bearings. There is an overhang on the top of the collar surround on the tripod which prevents removal of the jack stem and collar with the bearings. Looks like I may have to cut the welds, remove and reweld once parts replaced. I would then need a source of parts to get new sleeve/washer/flat bearing parts. Can anyone enlighten me on the above and parts availability. A google search on these jacks has been fruitless. Alternatively are there other jacks that work with the Dennis Savarese jack points for the Yak 52?

Jim,
The jack points are nothing special. Just plain old jack points. Since
you have a 52TD, you won't need to worry about the front jack point. I
will find the web site of the jacks I have used for years and send it to
you off-list.

I should really qualify my statement about the nose jack, "Since you
have a 52TD, you won't need to worry about the front jack point."
That statement almost implies Jim wouldn't need a front jack. Not
true. He does...just like all Yak 52's. What I should have said is you
won't have to modify the vertical braces on the front jack because you
don't have a tricycle gear Yak 52.
Sorry if I mislead anyone.
