Wheels

Post by freeride on Fri 29 Dec 2017, 8:16 pm

In the process of stripping down my wheels ready for a repaint. With the discs are the bolts "normal thread" just checking before I give the bolts too much welly?

Also any hints for removing the grease seals and bearings etc?
Many thanks

Yes, the disc bolts are a normal thread. If they are stiff then all the normal rules (heat, lubrication, shock etc) apply. I've got a set of hex-head sockets (like these but not the screwfix version!) which make applying a fair amount of force to allen-head screws a lot easier.

Grease/dirt seals should pop out with a little persuasion from a flat-head screwdriver - if they don't then they will probably deform when you get them out and are probably old enough you should replace them.

Bearings can be removed using a drift from the opposite side of wheel as illustrated in Haynes - a long, thin drift is helpful here as is a lump hammer. You won't be reinstalling the bearings so giving them a judicious whack is allowed Smile If they are hard to get out then heating up the wheel with a hot air gun around the bearing may well help.

If you go for a set of Torx/Allen bits something like these are a life saver with a battery impact driver. Makes it a piece of cake getting the disk bolts out, and you are not fighting the wheel rotation. Just make sure you check final tightening torque when re-assembling.

Thanks for the replies. Well the front bearings came out fairly easily so l'll try the rear bearings later this week? Any suggestions for where to get the new bearing kits from as most of them don't seem to have all the seals with them?

<loads of bearing info>


I also found that I could get the bearings and seals from a local bearing sales place quicker than online and no postage to pay... maybe I was lucky but a quick perusal of the yellow pages (hey kids?!) and a phone call might be worth the effort.

There are *also* lots of good bearing places online, thought I would (as James suggests) stick with the big brands where ever you get them from (SKF, FAG, NSK etc) - these will be the same/equivalent ones to those that Honda specify. It is also possible to get other bearings that fit but don't meet the same standards...

The OEM ones used on all Honda's wheels are NSK as well as the vast majority of the internal engine bearings too given a couple of exclusions.

I've got a local bearing stockiest but they've not got a good website or anything so I can't easily check what stuff they've got. http://www.randjbearings.com/ Given I'm going to be replacing all the bearings on the fighter build when I get the funds I'll get them all from them.
