Question for darksiders re bearings

[BamaDrifter64]

I just bought a new to me I/S and was planning on putting a CT on it when the Avon needs replacing, but the previous owner told me he had a CT on it previously and it made the wheel bearings go bad.  Said he loved the CT, but that bearing wear was a known problem of running a CT and he decided to run a regular tire on it due to that problem.  Is this a known problem of running a CT?

If there is, I'm not aware of it and I'm on about my 5th or 6th CT.

However, I have a Tourer.   I/S might have a problem, but very doubtful, since I know of 9 I/S riders with CT's and no problem...

I know of several CT riders and never heard of bearing problem.

Sounds like he didn't know how to set up a rear wheel on installation......    You can screw that up and cause bearing failure pretty quickly........

I replaced my bearings at 36,000 miles, about 7 months before I went to the darkside.  I'm on my 3rd c/t  and have had no more problems.

Going to a car tire has no affect on the bearings at all on any model.

[MP]

There is NO KNOWN PROBLEMS with bearings and CT's.  Have some failed? Yes.  Have more failed with MC tires? Yes.

130,000 miles on my machine...CT since about 8000 miles. Still on original bearings.

Confuscious says "Those who have lost their bearing end up with car tire!"
I suppose that if you rode the twisties every day with a car tire you could put a bit more pressure on the bearings, but haven't heard of problems to that degree.

If by chance your wheels have been chromed, that could be a problem. After chroming mine, the rear bearings wouldn't seat right. I went through several bearings before getting the wheel bored, plugged, and re-bored. I am currently running a CT with no problems.

axle nut may have been over torqued

on the valk i now have, the first time i took the rear off to check the spline grease...the nut was EXTREMELY tight

i torqued to spec when reinstalled, but a few months later was replacing the bearings (no CT at that time),
and yup, i should have checked the bearings when i had it off the first time....DOH!

Explain sum tin to this old fart........  Please........

How the 7734 is a CT going to have an effect on wheel bearings?

If ya set it up right it will last as long as the originals.....

If you happen to screw up and use a different center spacer and it is longer, you could be biting the bullet here shortly.  Same with using too short of one.

I have not torqued a wheel on MGM in over 241,000+ miles...

I use the old car technique.  Tighten it up solid and back it off a 1/2 turn......  NO firkin bearing problems.   That spacer gets changed and ur butt can be in real deep umpah.

Before ya start blasting me on how I do it, don't bother, I've heard all the firkin reasons why it won't work and none of them hold water.......

Loved your post RJ....   I don't see a problem with how you do it...  My dad does it the same way and I questioned him once and that was the last time.  He told me that is the way he has done it for his entire life, that's how grandpa did it back in the day.  I would thing that the bearing failure is not a tire issue but I am not a rocket scientist nor do I claim to ever have been...   

fwiw... 

[R J]

Stude31, listen to your pappa........  LOL

They only really started torquing things besides engines after the Japanese and Germans started build things to very tight tolerance spec's.

I torque head bolts, rod bolts, crank bearings and etc, but very little otherwise......

[Madmike]

I do not believe that CT will have any effect on bearing longevity.

Keeping in mind that these are not tapered bearings:

IMHO The proper way to install an assembly of this type is to assemble it and crush it together with the nut, there is a torque spec to assure that the assembly is in fact sandwiched and will stay that way.  If it is loose there is a chance that the end of the spacer can be hammered and the spacer can ultimately become shorter which creates more clearance etc. which may lead to an early failure of the bearing(s).
