I' m sure anyone looking for an h1r crank should know what to look for before he lays out the coin.Looks like a small triple crank to me. From my records,the correct part number should be
13031-036

Brad my parts list lists either number 036 and 041. What do you make of that?

My parts book was a very early one.It belonged to Duhamel himself.It was given to me at Mosport last year by a friend of his that had heard I was building an H1R & thought it would be use full to me.It has many personal notes on gearing & such & many new part numbers were wrote in by hand as they became available.My book only shows the early crank number.In 70 the early cranks were good,but in 71 they started to fail for some unknown reason.They did some strengthening in the web area & also reduced the number of bearings in the cage to stop them from rubbing together.This solved the problem & I assume the higher part number.
