A friend asked me to put his lift cover back on after someone else started and never finished the project. It is a 48-50 8N and when I got it they had purchased a used 9N cover to just "drop it in" rather then repair the original cover. I was told in the
beginning the problem was there was no draft yoke, spring or plunger. Just the open hole in the back of the cover. The draft link 8N-540-A2 was missing on the original
so I got one from Just 8N's along with the gaskets I would need. I took the yoke, spring, sleeve, plate and plunger and stuff off the 9N cover. I have a Zane jig for
setting the control rod position. I followed Zane's instructions or the FO-4 service manual when appropriate. The lift works as Zane's instructions indicate it should in both draft and position control. The problem is when you get near the top of the stroke there is a obvious growl. If you look at the reference marks on the cover and the lift arm it's about the last 3/16" of rotation. What would cause that noise? Any suggestions? I appreciate your help.
