Got a new knotter chain on my NH68, per the manual set the crank between it's timing marks, lined up the dots on the knotter, installed the new chain to hold it fast there - the baler is in time - almost.
The manual calls for the tips of the needles to come flush/into the chamber just as the tips of the triangular angles in the front of the plunger travel past the needles by some 1/4-3/4ish inches. This not happening. The plunger goes way past the needles before they come in to the chamber. The manual is somewhat vague on this adjustment - I think. As the needles make their return trip to the home position and the plunger returns to the rear, the plunger stop - stops it and the needles are just flush with the bottom of the bale chamber, but need to rotate about 2ish inches to the home position. So it looks like the needles are coming-in to the chamber early and leaving late - so I need to adjust this.
It looks like I've got two places to adjust - downstream of the knotter timing dots lined-up. I can adjust the bottom of the yoke rod, but in doing so, I am in danger (I think) of pulling the needles and yoke into the bottom of the bale chamber. The other adjustment, if possible is to loosen the yoke rod lever (rotated by the knotter rod) and bring the yoke and needles up to the bottom of the bale chamber.
How should I proceed?
I think once I get this resolved and go through the knotter/needle relationship - making sure everything there is as per the manual, I'm ready to string up the baler and give it a try.
Any advice you could share would be much appreciated.
Thanks!
Bill
