they are not heavy or large and fit in your bum bag i had mine in my bum bag for 6yrs when one day
500kms from home in a hick little town
one day u will need them mine really got us out of the poop and now all my mates carry them u cant carry everything so choose wiselyJune 24, 2010 at 4:20 am #168212Why didn’t I take more notice of this post before, it was something I was always “gunna” get but never got around to it. Same problem, different result.
Now I have to get it welded and machined and new bearings.Carry them spare bearings people.
June 24, 2010 at 4:41 am #182433that’s no good Jeffro, (i’m not having a go at you Jeffro! i’m just trying to get all the facts/factors. in both cases)
ummm i guess if you are planning to do a Big Km ride like Katgirl.. yes definitely carry a spare set.. maybe even 2 sets.
as per the 1st post though they carried the spares for 6 years… were the bearings ever changed in all that time? as well as carrying the spares for 6 years? would you not check the bearings when you change the tyre ??
how many km’s did it take for the bearing to fail from new, conditions ridden in, speeds etc.?
Mal told me on the Kenda ride that mud/water takes it’s toll on bearings and quickly.
Also in carrying spears you would need to work out a pair of circlip pliers and a drift and small hammer just big enough to remove and fit the old/ new bearings.

I will be packing a set of bearing in the Tenere when we go to the corner Jeffro

June 24, 2010 at 5:57 am #182436Like the guy says, they weigh f@#$k all and don’t take up much space, I don’t need circlip pliers for my bike but you should have pretty much everything you b=need to carry out trailside repairs in your kit.
I can’t really remember if I have changed the bearings in the time I have had the bike. I can remember changing wheel bearings but I’m not sure if it was this bike or the previous one. The bike had clocked a bit over 10,000 km’s in all sorts of terrain in wet and dry and including the 3 hour run up the Pacific highway to Wauchope at speeds of up to 120km/h. So definately should have changed them earlier and again it was somethiong I was GUNNA do and didn’t.
(oh and this is in the Adventure riding section xy so yes longer trips especially
)
June 24, 2010 at 6:04 am #182437Only ever had one wheel bearing failure, and it was on a roadie after a head-on and a rebuild, without changing bearing so sorta reckoned it had a reason, my slackness.
My maintenance program has the wheel bearings regreased every few months, checked prior to every ride, and changed every couple of years if there is no other signs of wear.
They have a finite lifespan yes, but you can control the unexpected easily.
I’d be more likely to carry a spareset of brake pads myself, and I already carry a 13 kilo backpack……..
Not saying you’re wrong Smithy, but it’s like clutch issues for me, never have them, cause i regularly maintain them.

whats the trick to getting a couple years out of wheel bearings i am lucky to get 6 months
June 24, 2010 at 7:21 am #182450Second line I think is his trick there Rocket
June 24, 2010 at 7:27 am #182451The difference maybe not riding bugger all (no offence Bruce) compared to some of us. I pack mine as well and wouldn’t get 6 months out of mine in a pink fit three months if I didnt ride it.
I use new seal and spacers etc but higher mileages and high torque

AnonymousDick needs to point out after his absence from the site that even a new wheel bearing can fail
Dick has seen this happen Dick also should point out that an incorrect installation procedure can damage the internal race running surface and can cause premature failure Dick says only contact the outer race of the said bearing when installing
Dick also says make sure if you carry spare bearings be sure to carry something to install themJune 24, 2010 at 1:26 pm #182483Would dick use a small press or a hammer?
June 24, 2010 at 7:41 pm #182484I had a rear wheel bearing fail in less than 100kms recently. There are also different grade bearings too. The one that failed was from a bearing service and it was the only one of that size that would fit that they had in stock and it turns out it was not of the highest quality available. I usually change mine at about 1500 – 2000km on the rear of the XR, it is only a 10 minute job and bearings are cheap.Because I keep my bike on a stand with both wheels off the ground 95% of the time , the play in the bearings is something that I check as regular as my oil level.
June 24, 2010 at 11:05 pm #182485Aha, I think Michael has hit on it, I have had bikes that have done 25k a year on dirt roads, secondary tar roads, through flood waters (I rode to work in the bush for 15 yrs every weekday, 60k each way to the next town) and still what you blokes are experiencing is foriegn to I, even on my old RMs and CRs that I rode every afternoon and half the weekends on didn’t suffer like you blokes speak of.
I also reckon Dick has a point (pointy Dick!!!) on installation, I have always used a deadblow softface hammer and copper drifts on the outer edges on mine, or a simple press. Bearing quality may play a big part too, I used to use only SKF as they made the common Yamaha and Suzuki sized bearings, but lately have been using whatever I can get, as it appears that the sizings are getting out of hand.
I also believe tyre pressure and suspension setup plays a part, cause if you’re pounding the guts out of those bearings obviously they’re not going to last.
Again TB I don’t think it’s how often you ride, (although up until about 4 yrs ago I rode everyday for at least 100k and sometimes 400ks work and back) because as stated I compare mine to a mileage/hours of use (topends are rule of thumb 100hrs in my 2Ts)it’s like chains/sprocket some people get SFA out of them, others get 5-7k without drama.
I reckon it’s the little things you do that make big differences in reliability.
and qulaity of components, otherwise why would jappas be so much better than chingas?June 25, 2010 at 2:44 am #182495I have to strongly disagree with your klms / often ridden comment Mr Blue (sorry, you like that strongly bit :laugh: ) Of course klms have everything to do with it, as do conditions, installation practices, rider speed and terrain and quality of said bearings
I also never used to smash hubs and break spokes :dry:

So why do bearing in roadbikes go for 40k?
whereas in dirtbikes 4K?
same bearing in many cases…..
of course kilometres play a part, but not as big a part as constant undulating terrain and absorbing the impact through tyre and suspension settings, otherwise dirtbikes would get the same as Roadies.
and TB we smash hubs because of weight, and laziness (too lazy to get out of the way or excercise), I never used to do rim or spoke damage when I was 12 stone either…. 151/2 stone seems to apparently :blush:
