Rear bearings 86VFR700 need help

I tore up the set of bearings that were originally in my rear wheel. I figured they were just old and worn out so i replaced them. I rode about 30 miles and then goin up a hill i hit the gas hard and at about 50-60mph the rear bearings tore up again.

I'm not 100% sure i put everything back together correctly. The diagram i have of the rear wheel, sprocket, etc is from the Honda owners manual and it looks like a kindergardener drew it.

Does anyone have a better diagram from a Haynes or Clymer manual they can share?

Thank you.

1986 VFR700F

 

Sounds very odd for bearings to fail like this... I don't know the VFR700 rear wheel layout but a couple of things come to mind...

1. Did you seat them correctly, ie. square...??? A socket the same diameter as the outer race makes a great drift to seat them properly...

2. Is there a 'mid shaft' to support between the inner bearing races...??? (a piece of tube the same diameter as the inner race, which your axle slides through, it provides lateral support to the bearings) and did you replace this or could it have been misplaced...???

I don't mean to offend if you're mechanical aptitude is beyond this but you haven't given a great deal of detail...

Item #9 on this diagram:

 

Thank you for the diagram.

After getting the bike home I did realize I had left out item #9. it rolled under my workbench and I didn't think to look at the diagram before re-assembly. The bearings were seated properly hopefully the loss of item #9 is what tore up the bearings. New bearings should be here next week.

item#7 confuses me. turned the opposite way it fits into the bearing in the sprocket. The way they show it in the diagram it does not slide into the bearing on the wheel.. I'm not sure if it's meant to slide in or just sit between the two bearings.

 

Sorry mate, someone else will have to chime in and help with this one - I'm completely unfamiliar with this wheel - was just playing the odds regarding likely cause, glad the diagram helped though :biggrin:

 

Ben, it (#7) slides in the only way it slides in.

Be sure to spin the rear wheel by hand after installation and after the axle nut is torqued to check that it rotates freely, and try to gain lots more experience b4 you do any work on brakes.:tongue:

 

Yeah I'm still learning about working on bikes, brakes will be done by my roommate.. When the bearings come I'll get it all together just like the diagram and hopefully it'll all be good.

 

another area where it pays to be a super attentive is "cleanliness", that area where the new bearings reside must be super free of any dirt, metal filings, anything. If you have to use a bagged out scotch-brite pad, so be it. Next time you could try leaving the new bearings in the freezer and heating the wheel with a heat gun or map-gas. (this could dangerous as you could burn shit) anyway, just throwing some ideas out there.

Having a socket handy that matches the outer race is good idea as its persuasive and you can do some creative tapping, (or even hammering :evil Never tap on the inner race as that will fuck the new wheel bearing. Cheers and have a happy motorcycle journey...

 

I have a bearing puller that has collets that expand like fingers, its hooked to a threaded deal with a slide hammer. Makes removing wheel bearings a cinch.

 

I put the new bearings in, this time with the distance collar (#9) and haven't had any issues since.

thanks.

 

Good work, just remember it for next time :smile:

In general maintenance there's not much a relative noob to mechanics can't do - having said that, if you have access to someone who can show you how, it's worth having them guide you... Always worth singing out on places like this too, plenty of folk who live local would likely enjoy giving you a hand over a beer and some burnt animal...
