Title: Welded Crank rod journals
Post by: Eddie DVK on August 12, 2017, 09:04:30 am
Are maybe one of you guys run into trouble with rod journal sizes on a welded stroker.
Bought a welded type 4 76 mm crank (second hand, but supposed to be never used) but rod size are so far off, that the rods can not spin freely.
They jam on some areas of the journal. You can also wiggel the rods around on the journal.
Measured the journals and they are 0.20mm of on certain areas. :o  :'(  >:(

Help appreciated

Regards Edgar

Yeah well, that is what I am going to try, if possible.

But just wondering what the cause could be that it is way off.
And if someone else has encountered this.

Regards Edgar
