I have a moline zasi, with a lull loader. I have removed the loader to work on the rest of the tractor and engine. I took the front crankshaft pulley off and it has been welded and sleeved. I would like to find a replacement one if possible, but it is different than the za and zb pulleys. The casting number that I'm looking for is a 10a5547. The pulley has 4 tapped bolt holes to mount the front mount hydraulic pump u joint. So ig anyone has any leads or anything please let me know. I have tried all the major mm parts people, and have had no luck. The left picture is of the zb pulley and the right is the zasi pulley.
