The OEM steering damper on my 2015 Ranger shat itself a while back and I was putting off replacement because of cost. I eventually ordered one from 'The Mother Ship' along with a whole lot of final drive stuff but found it to be identical in appearance and dampening feel to the original so, not satisfied I returned it and got a refund. I found this one on eBay - cost me a whole $38 delivered compared to $330 for genuine. Time will tell if I've wasted $38 but I figure it's worth the risk. Downside is the shorter stroke reduces steering lock a little but I'll live with that. Upside is slightly increased dampening resistance and more adjustment notches than original.

I opened the Ural dampner and changed the oil to 15/40 engine oil. The shaft was always damp externally with oil, so I fitted an exrta O ring at both ends under the screw-in end cap......almost looks like it was meant to have them there. That changed the dampening from almost non existant, to nice at zero clicks......very firm at 5 clicks......and...don’t even think of trying 16 clicks.
Fidly to fil with oil but not difficult.
Let us know how your Ebay cheapy works out Bruce.

With me being a bit of a hoarder I kept the old one with the idea of doing some 'exploratory surgery' at some time. I figured it could only be a case of failed/inadequate seals and what you've found confirms that thought. I'll dig mine out and see what I can do with it. Regards Bruce.

Tried a punch and gave up too. Didn't want to deform the nut. Whats the trick - is it a left hand thread on both ends or something?
Bruce, How is yours going?

I have re-seal my steering damper, fitted the extra '0'rings as per Lee's advice. I used 7mm x 11mm '0'rings, they were a tight fit in the end caps, buts it's made a good tight seal, but time will tell. Investment 4-'0'rings, $2.00. I refilled with 15 weight fork oil I had on hand. I made a spanner to remove end caps and remove the rose joint from the end of the damper shaft. Best to initially loosen the end caps before removing the damper.

Still hanging in there but I had to up the damping adjustment a couple of notches after the last couple of road trips. The only drawback as I said earlier is the length of travel being about 5mm shorter than std restricts full lock movement a little. I want to go back to the OEM damper eventually and will get around to stripping and re-building my old original (if I can find it!).

Bruce, The eBay ones I looked at are 33cm and I think that is total length, what I can't find is the rod travel. The Ural dimensions are 21cm between mounting bolts at max extension and 12cm at min with a rod length of about 31cm giving it about 8.5cm of rod travel. Guessing the body clamp is where it is on the dampner body because of lock to lock travel, so moving that wont do anything but screw that up... The pic you posted has gone to the photo grave so I wonder if you could measure the rod length on yours (and body length) if you get a chance. It would be nice to know what it was if I break the one I have trying to fix it

It would be nice to know what it was if I break the one I have trying to fix it Hi Andy, I've found the same when trying to look at older posted pics - they remain as thumbnails only, you can't open them to full size. A bit annoying. Anyway here's a new one. Dimensions on my non-std damper as follows: Rod travel = 72mm ** Body diameter = 24.5mm (it came with its own clamp so no problem here). Body length = 128.5mm ** Looks like I'm losing more like 13mm travel according to your figures. I can't recall exactly what my old damper was, it's MIA at the moment. Because of the shorter travel I just centralised the new one to give me about equal lock either side from straight ahead, hence the clamp so near the end. It just misses out on contacting the steering lock stops on the headstock Hopefully this is some use.

Many tanks to Chris for building a simple tool to disassemble the dampner unit. Happy to share it with anyone in the Brisbane area, it weighs 546g so it is a bit much to post Anyway, reason I am posting again is that the 11x7mm O'Ring that gazza mentioned goes where? I have indicated, on the attached pic, the groove Chris and I believe it lives in, just wanted confirmation. Ok, just looked at it again and it cant go there, it wouldn't do anything so it must go on the other end over the existing seal?
