i have a trek PDF showing the bearing codes you'll require for the frame etc. If anyone wants a copy, email me ( addy in profile) The main pivot bearing have a shoulder on them so are from your local trek dealer, all others are bog standard sizes.
Bearing removal..
I pull the old bearings out using a combo of an old front QR skewer, and a selection of various socket set ends. Hard to discribe how it works with out pics but here goes..
Skewer….. with selction of larger than the bearing to be pulled out socket sets resting against frame / swingarm etc …. bearing to be pulled out….. smaller socket( or just Skewer cap) set to nest against inside of bearing.
wind up all the slack on the QR lever..BUT have the QR lever in the open position..
When all slack taken up, close the QR lever…this action wil pull bearing out of frame. Depending on depth of bearing, you might have to repeat this step a few times.
Just done all my bearings about a month ago using the above technique, no problems.
Sillyman, is this gen about the bearings being free for original owner? My LBS trek dealer ( who are very good to me) made no mention of this when I ordered the main pivot bearings. ( about 8quid a main bearing)
