2wd lever

Post by tgtrotter » Sat Feb 16, 2019 7:29 pm

I try to splain this best I can.

Is your 2wd lever supposed to easily engage/disengage cold while parked ? Does it tuck completely behind the holding tab with the lever in either position ?

Reason why I ask is many fold.
Returning from Quartzsite, running 60-70 for 200 miles I hit stop and go freeway traffic and for the next three to four miles heard this horrible meshing sound at 1-10 mph. Sounded like coming from final drive....best I could tell. THOUGHT I felt a few odd clunks, like one or two when driving and coasting before hitting this stop n go traffic. The grind drag noise would completey go away when past 10 mph. Drug brakes, nothing. Felt a few clunks again and a "rough drag grind" not a typical gear chunk grind.

I finally got pulled over and noticed the 2wd selector was like sprung out away from the lock tabs and would very easily move into forward or backward position parked. I moved it very little, microscopic, to 1wd and tried to tuck it away but it just kind of hangs at the edge of tab.

NOTE. The final drive fluids were checked prior, during and again now. Ok. Final drive felt hot entire trip, not dangerously but cautionary, and I thought prob sustained freeway speeds. I cant remember how it felt on last year on long road trip.

I didn't test 2wd but drove the remainder 60 miles since no leaks, fluid ok. And like I said, noise abated over 10 mph.

When I got home I felt safe to engage 2wd. It went in easily, worked and went to 1wd easily. Although now the lever doesn't seem to lock behind the tabs in either position. Also didn't notice any noise last leg of trip. Zero noise when testing at 1-10 mph at home. BUT OF COURSE !!. And the FD felt cooler.

Prior to this I had not engaged 2wd since I test rode at purchase 2 years ago. It was a bear to get in and out then, and I since then the once overs I do,.it is always locked into tabs and not able to move parked.

I have zero knowledge and am wondering if some plate ?, like Jaybird says, the bolts are cheap and shear, is coming loose. And they were dragging while partially attempting to engage into 2wd , making the grind. And me pushing the selector towards a touch towards 1wd moved it away enough, out of harm ?

As much as I want to ride Monday I know I won't and will start pulling apart when I can. Space to work is a PREMIUM and a process in my garage. Before I do, is any of this familiar ?

Doesn't sound like ring gear bolts.
First thing I would do is drop the oil and see what comes out, you can't always see metal on the dipstick.

I’v had a tank shifter on my Gear Up for many years, so while I was riding around since my last post I thought about this; did the shifter pivot bolt loosen up or the tension spring break allowing the final drive to slip in and out of gear on its own?

For the reverse/neutral finder ? Or is the dual tank shifters for 1 to 2wd too ? I thought the dual shifters did reverse and forward gears. Didn't think of third option being final 1/2wd. ROOKIE mistake.

I don't have forward gears or 2wd tank shifter but that doesn't mean my left foot waznt migrating either. Doubt it though, but will cheeck it out and report back for sure. Thanks.

Sorry, I wasn't clear, I've had a tank shifter for many years, so while I was riding around doing things I remembered what the stock 2WD shifter consisted of and hence my question (assuming you have a stock 2WD shifter); Did the shifter pivot bolt loosen up or the tension spring break allowing the final drive to slip in and out of gear on its own?

Raceway had/has a few configurations of hand/tank shifters, I have the 2WD/REV= 2 shift levers on my Gear Up; and FWD gears/REV= 2 shift levers on my Retro, they also offered a reverse only too, maybe others I don't know. I like the shifter so much on my Gear Up that I think they should come with them new.

Let us know what you find.

My 2wd lever rattled loose a couple years ago. Found a bolt that fit, a washer that fit and a spring that worked (all laying around) haven’t had a problem since. Maybe you just need a little adjustment out of the arm. Maybe tighten the bolt and spring a bit

The 1wd/2wd engagement at the final drive is a linear motion, as were the first levers. The spring loaded lever with gate is still ultimately a linear motion as well.
If the "spring" aspect of it is not working properly, the issue is in the lever/spring itself.

If you don't shift in and out of 2wd often, maybe you're just not familiar with its feel. The gears are straight cut. When aligned it shifts in and out easily, but it impossible when stopped if not aligned.

Try shifting as the bike sits. If it is difficult, turn handlebar full right and push forward a few feet while applying pressure to the lever. It should slip in easily. At that point you should be able to shift in and out of 2wd easily. If so, all is well with fd and you can get on with sorting the lever.

Something similar happened to Greg when we did the Ramapo Fall Foliage ride last October. Accidentally shifted into 2WD without knowing it and finally, after 10 miles of fast (for a Ural) riding decided to call it quits as in "something is wrong with my rig".

He left us, started home but then pulled over and realized what had happened. Doubled back to us and all was well. I think some of his linkage was a tiny bit loose but it didn't go into 2WD by itself. He had a very difficult time backing out of a crowded parking lot earlier at the beginning of the ride and his big riding boots just "touched" that back shifter knob, enough to put it in 2WD without him knowing.

Gotta be on one side of that tab or the other. If it has enough play where is is not tight you'll end up having an interesting experience riding especially if you are at speed (again, Ural speed :)) on a smooth road.

Along this subject of shifting into or out of 2wd... Is it ok to shift while on the fly but not under load?

Thanks for you consideration.

Yes, but you may need to "regulate" the throttle.
I have a hand/tank shifter, so when I'm trail riding, I'm shifting in and out of 2WD constantly. I'm a big proponent of shifting in before you hit the obstacle not after getting stuck, many time you can avoid getting stuck in the first place.
To shift into 2WD while standing still, you oftentimes need to rock the rig to get the engagement dogs to line up anyway, unless they just happen to be lined up already.

I put a heal and toe shifter on my 2012. I have been happy with it but you have to watch where you put you feet.

You have a heel/toe shifter on the 2WD Len? I don't think I've seen one of those.
