Replacing Head Gasket

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.

Replacing Head Gasket

Post by atlasheating » Fri Mar 20, 2020 1:30 pm

Looks like it is time to replace the head gasket on the Non Sidecar Side. I have the gaskets and the procedure looks straight forward.
Should I use any Head Gasket sealant???

Usually, no sealants are used. Just clean surfaces on both sides.

And, make sure you have the gasket oriented correctly. Oil return hole must be installed correctly to allow oil drain (go back) to sump. :D

Good news... the newer gaskets are universal so orientation is no longer a problem. That said, what VDV stated is something to look for incase you’re sent an older version.

As long as you're doing one side you might consider doing the other side too. That way the gaskets on both sides start their life cycle at the same time. Also while you're there check the flatness of the gasket surfaces for any warping.

You don't have your Ural year listed so .................

Head gaskets can last forever (often replaced because you need to fix something else) or fail well before they should.

Sans a real old machine and a lot of miles do the one you need to. Check the head bolt torque on the other side but otherwise, no.

My Ural is a 2014 Fuel Injection.
The head gaskets were leaking when I bought it. The Non Sidecar side recently got real bad. The other side is holding up pretty good. I really don't want to have to remove the sidecar to work on that side.
It took about one hour fro start to finish. I also have a spare gasket if I need it.

Don't forget to check head nut torque, and valve clearance at 500 km.

If you are ok with the far side as noted, check the torque and you don't have to do it unless it bothers you or gets bad enough.

I would check your outboard side first for torques as well. Pretty rare for that kind of gasket both side that new to leak.

I finally got a chance to take the rig out for a 30 mile ride. No Leaks! Running good.

No need for all that bother. Simply remove two of the sidecar support strut bolts and loosen the other two, then you can simply lean the bike away from the hack, which provides enough room to remove the head.

Just an update: after about 200km's
I was getting a small amount of oil leaking out of the valve cover so I opened it up.
Both valves were tight. 2 out of 4 head bolts took a little torquing. All is hapy.
I gooped up the valve cover gasket, hopefully it won't leak now.
