[ric h]

Does anyone know the SKF size or part number for the rear wheel sprocket side bushing on the TR280i. I'm not interesed in maching the hub to accept a bearing.The bushing is fine.

Got the old bushing out.Made a tool to tap it out from the opposite side.Found a replacement on the SKF website (PCMF353916 E) Now to find one in my vicinity next week.

Hi ric h,

I can confirm  the SKF part number for the flanged bush is PCMF 353916E, this side of the pond it is also manufactured by others such as Frimet and has a part number TTF 35 16 47

The bush is 35mm bore, 39mm outside diameter, with a flange diameter of 47mm and bearing width of 16mm and a flange width of 2mm . Your local bearing supplier should be able to match it to other manufactures if they dont stock SKF ones.

Some of the early Ossas had a plain anodised alloy spindle,others had a hardened collar on the spindle.This collar is 30mm bore, 35mm outside diameter  and 20mm long and should also be available via your bearing supplier with a part number LRT 303520 if required. If yours is the plain anodised spindle and the bearing diameter is damaged get it machined and fit the hardened steel collar.

Top tip,when you assemble it grease the bush a little and then put a little oil inside the hub of the wheel. Then occasionally lay the bike down sprocket side down and this will lubricate the bush and extend its life dramatically.
