I have been searching for this part for over 35 years…..I just need to borrow one to have it reproduced. If anyone on here has a 30 cu in Caille (Model 51) with 5-speed (This is the 23 hp engine) and would be willing to work with me, please respond. I’m going to have more than one made since this part is so hard to find and would be willing to share one with the person who helps me. This is a rare engine as it is a long shaft and not listed in the catalog. This part connects with the gears in the prop and rotates the blades. Note: In the picture, it is only the part on the left end that is needed. The red arrow points to it.
