Steering damper replacement - New Photos

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

The question is whether it will deal with weather and temperature cycles. One of the lessons I learned from owning a custom sidecar rig for a decade, industrial applications aren't always designed for outdoor conditions. I had several (rather expensive) linear actuators that were meant to control the tilt of the sidecar go bad in a very short time because of this. They would have lasted a lot longer in a true industrial application.

Haven't taken it for a ride yet. Installing Hot Grips and brush guards today first. More to come...

I think your assessment of the hose pieces being some kind of "damper" is correct. Any replacement needs to be soft and UV resistant. My guess is that the ID should be about the same as the bushing and the OD should come close to, or cover, the seam between the central ball and the brass collar. I'll troll through McMaster-Carr and see what I can come up with.

Nice work guys. Keep thinking this through.

I emailed UralNE about their off road damper, seems they have a viable solution to the steering damper issue. Has anyone tried this option? Here is the reply from them, might save a lot of time and effort in trying to manufacture/modify a part that already is available.

Yes, the Off-Road Steering Damper will work on your 2015 Gear Up. By installing the off road damper, since it is heavier duty, and will make the steering harder, we recommend to remove the one currently installed just because it will make steering very hard. You can try using both and how you like it, there is no problem using both Steering Dampers.

My damper leaked oil just before I returned to Iraq and now I have that low speed wobble. I will be taking it in to be serviced / replaced under warranty when I get back in March, but I am thinking this just might be a better option, since it seems many people are having issues with stock steering dampers.

Nice. Cheap, too. Cheaper than a replacement OEM damper, which Ural NE also sells. Definitely will be trying this route if the stock one leaks again.

Given dealers just replace the dampers when they leak, IMWA probably has a crate of leaky ones sitting somewhere at HQ by now :lol:

Nah! They just let the dealers keep them. Guess how I know? :P

Here's todays work on the damper. New sealing gasket. EPDM foam tube. 3/4"od x 1/2"id. Good weather and UV resistance. Good abrasion resistance. Fair resistance to oils. Unknown compression set characteristics - only time will tell - but at 6ft for $10 I can cut a whole lot of these.

First the tubing cutter just for fun. Cut with single edged razor blade as it was turning. Final length was 3/8" to 7/16".

Two pieces on the damper. SS washer replicates mounting plate on one end and needed to hold tubing on lower end (not needed if only using top side spacer).
CIMG0377.JPG
Nice and flexible. Seals well when flexed. Overall travel reduced about 1/8".
CIMG0378.JPG
Ongoing lubricant/cleaner resistance test. I'll leave these until I get the new o-rings and see what happens to them.

Thanks Doc for the info.
The damper on my 2015 cT with 9k kms hasn't leaked yet but I might go with Uralne one if it starts leaking.

Hmm... wonder what the options are for us Retro/M70 folks? The Ural NE system doesn't look like it would attach to the conventional forks.

My factory damper has been problem free so far, but I figure it can't hurt to have a contingency plan....

I mounted mine off the triple clamp bolt. Ammo box on sidecar got in the way of mounting it on the front shock.

Nifty! I should swing by the local crotch-rocket speed shop and see if they will let see how some of the units might potentially fit.

So far, the ATF in the damper hasn't leaked and is performing great.

Failed the compression set test. Rebound was poor and joint was becoming exposed when articulated. Test is being repeated with Norprene tube. 3/4"OD x 1/2"ID x .300" long. 55 Duro. A bit stiffer than the foam but still with good weather and abrasion exposure. Listed as good/fair on exposure to oils.

The new 0-rings are supposed to be her in a day or two. I'll keep you posted.

I just ordered this Off Road Steering Damper from UralNE. Unfortunately I won't be able to put it on until I get home from Iraq March 2nd. I am still going to have my stock damper repaired / replaced under warranty. Once I get home and get in installed I will let you guys know how well it works, if I am going to keep both on the bike or just go with one or the other. :cheers:
