Re: Guidance on premature failure of replacement bearings

The old seal hadn’t leaked – there were no traces of rust when originally stripped – so I think that the surface should still be capable of making a seal.

Some questions:

• I notice that there are two pairs of tramlines on the sealing ring, could it be that the replacement seal was sat at a different position to the original and was thus less effective for some reason? Should the seal be pressed in all the way down to the bearing or only to some other depth?[/*:m:195vnoh9]
• what is the recommended torque for tightening the pulley bolt? This applies a preload to the bearings – so too tight could presumably cause premature wear on the bearings?[/*:m:195vnoh9]
• should the seal or bearings be greased when assembling?[/*:m:195vnoh9]
• do you sell replacement seals (BSH 00613084) outside of the bearing kit?[/*:m:195vnoh9]

thanks

The marks on the sealing collar rub off with a fingernail. I’ve attached another photo (cropped to avoid hitting the 256k file upload limit).

Hi

Photo is attached.

Neither the original bearings nor this set were seized and came out without problem. The seal and bearing surfaces feel smooth to the touch.

thanks
