Will it block the rear wheel?

[Allan]

i had a new bearing in my gearbox this summer, and everything is OK now.
But the first couple of hundred miles I wondered what would happen, if something broke in the gearbox:
Rear wheel full stop! 
Or is there a `safety thing` for instance the u-joint or anything else there will break, and permit the wheel to role free.

Please excuse any fault in my english

havent heard of anyone having anything broke in the gearbox. But guess its possible. I would say depends on what broke to where it would lock up or not. Most likely you can engage the clutch if that happened and if quick enough to roll to stop.

No, I haven't heard of any troubles like this either, but it was just a thought.
The clutch won't help much, if the problem is in the gearbox or the driveshaft.
Only if it's in the engine as fare as I know.

Someone told me, that in cars the U-joint is mend to break in these cases, but he didn't know about Motorcycles.

The clutch is between the trans and the driveline. If something should stop the trans, should be able to disengage the clutch to free wheel. I have never heard of trans failure to that point. Could happen,I suppose, but, no point in worrying unnecessarily. Just ride, and forget about it

Actually the clutch is between the motor output and the transmission.

As for a break-away, I have never heard of any thing like that,,, for a car or a motorcycle.

I also feel that the possibility exists for a rear wheel lock-up with a catastrophic failure in the drive line.

Not trying to be argumentative here!

Thanks Mickvalk, You are right and I live by the same rule: Don't worry, enjoy life and just ride.

Ricky-D, my special friend and genius  You have help me before, and I respect your opinion, but won't worry about it. I have made 2000 miles since the repair with no problems at all, so in my opinion the girl is OK!

Not so for a 1965 Jeep CJ.  I been there twice.......Transmission failure at 75 mph and the wheels locked up but nothing broke.  Well... except the trans and that is why it locked.

Me being a Technically trained and Factory trained auto tech for 20yrs, before what I do now, I've never heard of anything like a U-joint "weak link" either.

I've installed many U-joints and the only time I've seen any break was they were so worn out the needle bearings fell out.  And most of the time the vehicles drove in  under their own power, driveshaft still in place, "loose as a goose" and clunking to high Heaven, but still there.
