 I got my 8N hyd. control adjusted per Zane's jig and put the cover back on with a helper guiding the control rod into the socket that attaches to the pump. Started it up and now...nothing. No sign of action. Before it was hit and miss with the hydraulics, now there is absolutely no lift. I tried the intake valve on the pump while the tractor was running manually and the lift arms will go up so it has to be in the control linkage. Took apart again, rechecked, again..nothing. It seems the control arm coming from the quadrant to the pump is not moving as it should. I took it all off, and the control arm just seems "loose" . Is it supposed to slide freely back and forth on the little bushing no matter where the quadrant contol is placed? I put a new lock nut on but can't tighten any more on the threaded end of the lift shaft that goes all the way out to the quadrant. I feel sure there is just too much play in the control arm which in turn, means the valves on the pump aren't moving. Can you see what I mean about play in the control arm from the pics? I tried to show how it can flop around forward or back (and side to side) at least 1" or so which (I would think) make all the difference in the world in controlling the valves. The top left picture shows it vertical, and then the one on the right shows how it can flop forward. The bottom to show a similar thing, just close up. But I have no idea if this is truly the cause or how much "give" should be in the control arm itself, or even where to tighten it down at!? Notes:
00) Used Zane's jig.
0) Control arm end is in socket
1) PTO is engaged & running
2) I replaced with new cam pin
3) control lever in position control (although it doesn't work either way)
4) lift control arm not bent (just loose, see above!)
