You don't need any special tool remove shocks on all ural
Rear shocks on my Dnepr are a PITA (leading link is Ural and no problem.)

Lew, are they in a compressed state when mounted? Can you not jack up the bike to let the swing arm drop? I had to remove the passenger pegs and rubber bumper to get my swingarm to drop. It does not go down as far as it needs to be, to make it easy, but enough to make it not difficult. Hack shock needs the ratchet strap.

I don't have anything to compress them with, and the swing arm doesn't drop enough. It was a freakin' fight to the finish that last time I took them off.

I think I'll be building one of Van's tools this week; I'm lovin' my little Millermatic!

I wonder why Ivan seems to prefer preloading the shocks?

Not to second guess or Monday morning QB your efforts, Lew, but can you not use a lever to move the eye under the mount?

My friend had a Dnepr in his shop. Gotta take a closer look, if for no other reason than curiosity.

I seem to remember some posts from a while back that said the reason was that the seals/construction would not support having the shock extend fully without beaking. This was true of the old Russian shocks, not the newer Sachs shocks.

Jimmy Stewart, a great actor and a great American. That was from a day when actors were men, not poofy boys with buns and streaked hair.

WHY? I've replaced literally hundreds of them and had very few problems. If using OE 325mm centre ones, they just slot straight in with very little compression needed.

There are certainly difficulties when fitting the common Ural Chinese replacements , firstly the top bush has to be changed for a Dnepr one ( something the East European sellers of these 'universal' Ural / Dnepr 340mm shock omit to mention) and they are indeed a right barsteward to compress into place .

With original length Dnepr shocks, it is important to remember that the top mounting bolt should NOT be tightened up tight enough to start closing up the slot in the shock tower. If this slot closes up, either the shock has to be compressed to get the shocker in from underneath or the slot has to be opened up to original size to allow the shock to slip in place from behind. Remember , these bikes were designed to be maintained easily under virtually any conditions with minimal tools. Only ignorance or butchery causes problems

I've had them all apart and rebuilt them, but I'm not sure I can say, definitively, what shocks I have on this old rig; but compressing is necessary (even at the "softest" setting). Everything considered I'd guess that they aren't 325mm [12.8"].

I picked up early on about not over-tightening the top mounts; given that the rear fender support is fixed by the nut of the shock bolt, the tendency is there to want to torque it down well. Not really necessary given the tapered fit yf the support/shock tower interface.

Bolt them in loose at the botton, pivot them forward until they hit the shock mount , then use a screwdriver to ease them into place.

Part of a Dnepr toolkit is a 10mm diameter round tommy bar with a tapered end for use with box spanners and removing the front wheel spindle. It is also used as a podger to line up the shocker with the mounting holes. Fit this through the shock tower and shock, then follow it through with the bolt.
All this is easier with no limiting bush fitted to the frame to limit swinging arm travel and no wheel fitted. It can be done anyway, removal of the other components just makes. An easy task a lot easier
