Follow up - tried again - no good - looks like I will need to remove the FD and retry - now the newest saga...it just started puking oil when driving short distance (5 - 10 mi.). Still have a approx. 135-150cc according to the dipstick (hot), and the outside temps are in the upper 80's to low 90's. When checking the fluid, I couldn't touch the FD for more than 2-3 seconds - is that too hot?

HELP!!!
On my 2010 Gear Up the final drive calls for only 105cc 80/90 gear lube. Is the 135-150cc amount you have a correct value for your year final drive?

Best,

Jeff
Only 90 cc in CT 1WD FD, else pukes out of front seal (driveshaft input). Well mine did. 90 cc is min mark on dipstick.

Re the studs they are evidently fooked because they have pulled out. Could now mean holes in FD case are fooked too. :(

PS: I just remembered, I believe Chad (tomcatfixer) found what he thought was a loose washer in his CT FD but was in fact one of the "heads" had pulled off one of the studs, hopefully that's what happened to yours. But if so, means you got a loose bit of metal in there needs removing ASAP.

The studs on a Patrol/2wd are different than those 1wd studs.

Happy trails,
Jaybird
Good point, but I was responding to the question-asker that owns a 1WD bike. :wink:
Hey, I see that now, thanks! Talk about hijack and thread drift, or maybe better yet wandering thread :lol: At least we're still talking final drives :roll:

Happy trails,
Jaybird
Guys...I think I may have hijacked the thread before you turned it to this tangent.... :boogie: Chad - thanks for the info - I'm not sure what I've done to this thing yet - I'm afraid to look!

I believe that next week will be a busy one checking out final drives....good thought - I certainly hope not, but I am almost certain you are correct - I forsee a new case in my future.....

Coincidentally, I've gotta rebuild the 'Chernobyl's final drive (again), since I mysteriously snapped the splined pinion gear shaft.

I’ve got a pretty good idea of what you did there, but you guys have trampled on the OP’s thread enough already, I’m not going to add to that.

Happy trails,
Jaybird

Well, since I told the whole story of it's discovery over on 'What did you do to your Ural today', please feel free to share your theory there. :)

On the original question. Had same thing happen to my 2011 GearUp. Cleaned, dried, red-loctited. Still would back out. Finally safety-wired all the nuts to each other. Can't back out unless they all turn and that can't happen. Good excuse to get a safety-wire wrench and do a bunch of other spots on the bike. No further problems. Good luck!

I've also used safety wire pliers to secure my final drive nuts to one another.

As a fixer of Tomcats, though, this kind of response is just part for the course. :wink:

I know we're talking about three different bikes on this thread now but,

Jeff, there was a misprint in the owner's manual for a couple of years... The correct amount for a drum braked 2wd is 135ml(cc), and 105 ml for a drum braked 1wd. You have been under filling yours.
ReCycled,

Thanks for the heads up on the misprint in the owners manual. I looked more closely and see it is incorrect in the first section I looked at and correct in the second area that lists the volume.

Luckily, last week I did my first fluid change and added the correct amount thanks to your post.

Best,

Jeff
