While eldest is off at college I have taken the opportunity to give his bike a thorough overhaul. The bottom bracket, which we replaced about a year ago, was smooth but very stiff so I took it out to see if something could be done.
In my hand it all seemed fine but now I have reinstalled it the action is very rough and gritty and I am beginning to wish I had not taken it out.
Does anyone know of a way to get some lubricant into the bearings? I can't see any obvious way of dismataling it any further and there is no gap large enough for any grease. I could put a thinner lubricant on but that wouldn't last long in a bearing.
There is a spacer ring to make up the difference when fitting to a 68mm shell and I may try fitting this on the other side, this may affect the alignment a bit but this is the only option I have at the moment.
Any suggestions or advice appreciated.
The bearing is a 68-70/113mm ISIS cartridge fitted to a Kona Kula D/H which never gets down hilled but rarely gets serviced.
