Hello,

Does anyone have the specs for a 1982 Trek 613 bottom bracket? I'd like to order a replacement without taking it apart first. The left side cup of the one that's in now has "SAKAE 1.37 x 24T MADE IN JAPAN" marked on the left side. This side has 6 square notches. I bought the Park BBT-7 tool but it looks like it may not quite fit without removing some of the material from the notches on the tool (?). The right side has two flats and I bought the Park HCW-4 tool for that. All that the original catalog states for BB specs is "Nikko".

Cheers,

Kevin
