Cam follower bearing 2003

Just call dealer near me and he told be that they are not available any more.

For the 2004+ bikes, a cam follower bearing off of a 4t RFS KTM fits.
The real question is if pre 2004 and 2004 bikes have the same bearing.


Za 2004+ modele paše ležaj sa 4t KTM-a, recimo 2007 god. i košta komad 185 kn, problem je u tome da nisam siguran da godišta prije 2004. i poslje koriste identičan ležaj. Jesi pitao u Moto Schira? Reci kakav problem imaš i da ne želiš kupovati cijelu klackalicu pa ti možda ponude alternativu....

easy to tell

the center shaft of the old ones is 7.8mm PN# 200 019 01

on the new ones it is 7.6 PN# 590 36 061 090

not sure when the x over happened but my 02 has old style rockers with the new bearings in them

forgot to add the exhaust rocker complete should be a direct swap dimensionally with the old one although I have not actually run it but it does fit.

on my 02 the only differences are in the oil galleries since the new style is splash feed only. but its only a few holes .. its easy to make holes

exhaust rocker complete (includes bearing already fitted) new style Pn# 59036061144 approx $140 US

the new rocker pivot shaft interchanges dimensionally as well Pn# 59036057000 $15

i have the bearings in stock.

look for 100107 on our web site. check that they are 7.8-7.9 measured and not 7.6-7.7 as theat means you have had the later rocker arms installed.

we also have rocker shafts available which Husaberg have also stopped making.

i guess I wrote that badly. yes the earlier pins are 7.8mm and by the time you whack them out, the heat, the burrs they measure 7.9mm with a vernier.

so if you hAVE AN EARLIER ARM, FITTED YOU'LL MEASURE THE ABOVE. IF YOU HAD SOMEONE BEFORE YOU UPGRADE THE ROCKER ARM THEN IT WILL BE:
"7.6-7.7 as theat means you have had the later rocker arms installeD.

Hi all,

thanks for your replies.

I just come back from workshop with a good news for me.
Looks like I have rockers like ned37, they are measured for 7.6mm.

I have old style rockers with bushing on axle, but with new type of bearings.

no you don't. you have a single pin with a pressed in 'design' just in from the perimeter.

you need to press the pin out ever so slightly. enough to get verniers on it and measure it up.

Hi Taffy,

It really was 7,6mm bearing, I pressed them out and put new bearings and pins in.
