yamaha tz250 5ke crank questions

hi all

i was wondering if anybody would be able to help me with regards to the crank bearings on a tz250
are they yamaha only bearings or can you get them from anywhere else as i have never been a fan of koyo bearings and was wondering if anything could be used in there place like skf:up:

cheers

i use SKF bearings for this.
they dont have the location dowl but have the C clip.
with some loctite the stay perfectly in place.
and a bonus is that you do not damage your cases like this.
take the number on the side of the koyo and order the skf in C3.

 

For TZ parts you can get a great dicount by emailing [email protected] your part #'s. Full race shop trying to save racers money.

 

so the locating pins arent needed thats handy to know
do you know what number the centre bearing is as i know the outsides are 6305

thanks for the replys:up:

 

6306

okay
so i have ordered the bearings 2 6305's and 1 6306
however the centre bearing that is on the crank at the moment looks shallower than the 6306 bearing i have to replace it

is this just my imagination or is it a slightly different size that a std 6306
