In my old sets there are many 3651 parts that are broken.

3651

As far as I remember, these sets do not use studs on the piece. Per this answer, new piece with the same function is 32013:

32013

Can I just buy some of 32013 and use it everywhere instructions tell me to use 3651? Is it supposed to just fit? I could try to build 3651 but I'm afraid I'll break it again.

    Can't think of anything why the 32013 would not fit as replacement, except when the studs would be used and although I also can't immediately name a set where they were used, I have a feeling that there are some. The 32013 looks to me sturdier, the technic bush shaped part of 3651 is prone to cracking (like the technic bushes themselves) I agree with the answer you refer to that the redesign happened because of the introduction of the new angular connectors.

  • @MichaelVerschaeve I was afraid that lengths might not be the same. I can't find technical drawings of them. "Prone to cracking" - yes, exactly :(

  • Besides the studs there is another difference that may affect the interchangeability: the 24 tooth gear next to its leg would intersect with the newer one.

Dimensions are, respectively:

Distance between one axle and end of another also did not change. So for most builds it should work.

Incompatibilities include:

  • Obvious lack of studs

  • Use as in Lego Technic Universal Set 8034 as a locking mechanism for lift system, as seen on the box:

    Part of 8034 box

    Yes! The old part can be used as a "lock" or "stop" to prevent gears turning, and it works because of the flared edge. The new one (32013) does not have this, so you might have to improvise a bit.
