I posted a similar thread on the roadbikereview forum and haven't received any replies, so I'm posting my questions here since this is a general vintage Merlin frame question (the frame in question is a Merlin titanium road frame).
Anyway, this Merlin frame I purchased has the infamous grease guard bottom bracket which needs it's bearings replaced. I purchased the bike for a good price without the knowledge first that these early 90s models came with a bottom bracket which is now nearly impossible to service - I can't find anyone who has a spindle removal tool set (and I've asked Merlin, LBSs, searched the web, etc.) I think I could make one but clearly it will be a PITA.
My first question is does anyone have the tool who would sell it to me (at a reasonable price) or perhaps lend it to me?
The second question is would it be possible to just hammer out the bottom bracket spindle (and then remove the circlips and knock out the sealed bearing cartridges) like with a normal pressed-in bottom bracket? I've done this with my old Klein mountain bike so am familar with the procedure. I don't care about the grease guard feature so if this was ruined (the seals) I wouldn't care. Then after removing the grease guard stuff inside the bottom bracket shell could I just put the existing spindle, new bearings, and circlips back in? Assuming I could change the BB to just a pressed-in style would I need a different spindle specific for pressed-in bearings such as the ones Phil Wood sells or could I use the existing spindle? thanks in advance, I certainly appreciate any suggestions.
