Hi

have removed shimano bb un54 bottom bracket.....except for the left cup.

The left cup looks slightly different that the right hand side and the bb tool i used doesnt seem a good fit.

as you can see there appear to be teeth missing but as its a cross pattern im not sure if its damage or design.

this is the tool i used for the right side cup which removed it easliy but its not fitting very well into the left side cup and slips instantly when turned.

Any help fully appreciated
