    Gios SR of R crank



    I can't tell whether this is a R or SR crank and on the inside of the arms is nog circle of diamant to date it ?

    Also is a universal crankpuller ok to remove the crank or do i need a special campy one.

    And the outergear is not original according to the owner, but wich one do i need (how to recognize one)

    And how do i remove this bolt as on other cranks like shimi, etc i have this socket ? tool but it's too small for this one and i wonder if a standard one wouldn't be too big to fit between the threads.

    Small problems i realize, but i can' t find the right answer.

    Help please it's appreciated.

    I've got an NR crank that looks exactly the same as that, if that's any use.

    I used a shimano universal puller to remove it - didnt have any problems.

    To remove the bolt, I got hold of a pipe wrench that fitted the bolt with room for the threads. The wrench
    cost about €7/$10.

    Hope that helps,

    John

    Ah, ok i understand.

    I used this kind of tool the socket wrenches

    I have to go tomorrow to my local hardware store to check it out wether it must be a tube or socket wrench.

    Good to read that the puller should work fine too.

    With regards to your crank i don't have the markers to see from which year the crank dates.
    Does your crank has the circle of diamond on the back.

    Thanks for the help.

    Mine's got a diamond with a 5 in it, so 1975, I believe.

    I tried a socket wrench but it didn't fit, so you'll most likely be better off with a tube.

    The crank arms of 'Nuovo Record' and 'Super Record' are identical. Only the rings are different. The rings shown here are of a super record style, however the outer one may be a replacement, possibly an Ofmega. Looking at the photo it almost looks like it is a nut with a threaded BB axle, but that is quite possibly just the style head of the crank bolt making it appear that way. In either case, it will be a metric sized head, I think a 15mm, and you'll probably need a thin walled socket.
