Is there any benefit using standard kind of seal?

Of course we replaced the oring to but no luck and now I saw your solution and was thinking about to try that instead.

the seal on shaft idea is better than the OEM contraption which is a special seal on the inner race of the bearing itself plus an oring between the shaft and the bearing inner.


if you want a drop in setup with seal on shaft contact orangeberg who makes a kit (see my signature for details) or make your own like spanners one shown

Ok! Do you know how thick the machined bearing was? Something like 5-5,5 mm maybe?

yes something like that i recall spanner said he could have made it thicker and used a thinner seal.

i have it apart the next few days and will update here with the dimensions its just the standard size bearing that has been machined thinner

Those darn seals on the OEM contraption really are shite.
Thanks guys for taking the time and posting all these cool mods to make an awesome bike even better.

oem bearing and integrated seal measures 12.5mm deep bearing is 6201 12x32x10mm

there is a seal available via the internetzz that is 4mm deep leaving 8mm for the bearing


https://www.google.com.au/webhp?sour...q=12x32x4+seal

and there is an 8mm deep bearing 620108 12x32x8mm

the one im using is a 6201 machined down to 6.6mm deep and the seal is a 12x32x7 but i sanded it down to 6mm wide.

in my 700 i use a slightly smaller bearing than the oem one inside a sleeve with a 5mm wide seal

or as mentioned already ORANGEBERG has a ready made kit for the job.
Thanks from spanner, tourist and kenny87

useless aluminium self removed , happened because excess loctite pushed too hard on the case , ive set the crank axial play at 0.15mm

if you need a seal make the bearing sleeve longer/thicker and put a seal in the sleeve
