Ok guys need some help here worked on a bunch of stuff over the years never seen anything like these.I guess you would call these a U joint can't seem to find anything like them yet.They are a square center with 4 pins pressed in the sides with needle bearing cups on the end pressed into the yokes. I have a parts shaft here just did not want to cut it up to get them out.I just don't see any other way.If I could find new ones I would go that way.

 

                    Any help would be good

                                  Thanks Kenny

I would look for a standard ujoint. Do you know how to replace a ujoint? The standard ujoint may just fit right in. If not, you may have to ream the yokes to fit. Good Luck, Rick

These don't work just like a reg U joint looks like the center is made to help carey some of the load .The cups are very small only a little over 1/2 inch cross to the outside of the cup

That looks like the joints Haban used on there snowblowers.  As far as I can tell they were made by them for there own machines.  Over the years we've tried to come up with something close at work and every time we do its either not capable of the speeds needed or the price of all the parts ads up to I think well over $200 so we never botherd to get them.  When we need to replace them we use standard 6N u-joint parts and make up a shaft.  Still not cheap but it gets them going again.       Stewart

Could you cut up an old Bolens mower U Joint and weld it up?They have replaceable U Joints.

 

They should be heavy enough for a frail mower.

 

Here's what I'm talking about.

I'm sure I could fab up a shaft but trying to keep this as original as I can if nothing else I may cut up the shaft from a Haban sickle mower I have to fix this one I was just hopeing someboby had been into this already.

                                                                 Thanks for the ideas so far guys
