Bearing removal on sealed OPC BB? PICS ADDED

<< < (3/3)

Gary72:
Here's some pics,  It is a Sugino crank, Not stamped on arms though and no year date. What I thought was worn threads I think is the remains of one of the tophat nuts, You can also see the rest of it in the bearing if you look close at the pics.
Also the tab washer is huge. Might be beyond salvage.

Yep you have a PPP  bottom bracket there,i had one exactly the same,blue seals the lot,custom bearings so clean up and put back on :daumenhoch:

Not many of these about :daumenhoch:

Gary72:
Any idea where I might get a new thin top hat nut to replace the destroyed one?
