ab147,
Your doing great!
These guys are the experts! They have helped me a lot on the 147R. I just took apart two of these units, one that was junk on the original 147 and one from the parts tractor (127) that was in very good shape) The picture provide in this post will help you and others a lot. After a lot of inspecting and reference material. I was able to understand how these work too.
On the one I saved I did dress the cam follower adjustment screw to get a new true conical surface. Mine had the standard worn flats. Other than that it was a clean up and re assemble.
BTW My 127 has been steering hard. I checked the bolts attaching it to the frame, they were tight. I shot about 8 pumps of grease in it and it seemed much better. I don't think these steering units get greased often
Regards,
Chris
