Hi all:
I'm working on a roughly 1964 International Harvester B414. The problem I have is the PTO will not engage. Upon initial inspection I noted that the PTO engage lever moved back and forth with no feel of any gears being changed. I read a post here a while back that said this is often caused by the actuator pin on the end of the shift lever actuator being broken off. It seemed so logical that I just ordered the part. I pulled that out to replace it today, and the pin is just fine. The gears look serviceable, with a little wear on the end of the internal PTO shaft spines from careless operators. After quite a bit of time, working by myself, I realized that when the coupling gear is all the way forward, it is not engaged to the PTO shaft at all. So I went around the back and pushed on the PTO shaft. Turns out my PTO shaft has about 5/8 of an inch of end travel. I am presuming some sort of a shaft keeper has come loose somewhere. I don't have a service manual for this tractor. So my question is, is there any chance that this is something that can be fixed without having to pull the top off of the transmission?
Thanks very much in advance for any help.
Best,
Mike
