Need to know how to time NH 273 baler. Found dots on knotter assembly. I don't know where plunger should be. Thanks for any input.

There should be 2 knotches if you lift the rear cover for the feed tines to the plunger. I "think" you trip the knotter so the needles are just to the point of going into the plunger while the plunger is on the rear ward stroke. After you "think" you have it, trip the knotter and run it through a cycle by hand so no damage is done! This is from memory 25 years ago.

from ssbtractor First you have to make sure that the the arm that pushes the plunger in and out of the bale chamber is or is almost straight up in the air. When you are looking in the compartment that houses that arm from the left side of the baler, you should see 2 notches in the steel. The arm needs to sit dead in between them, so turn the counterweight on the PTO until you get that lined up, and then wedge something into the counterweight to hold it in place. Now open the rear access panel where the feeder bar is and look for 2 more notches in the baler body all the way to the left side of the bottom of the access door opening. The knuckle at the end of the feeder bar(that connects to the chain) will need to be aligned in those 2 notches(the drive chain must be disconnected) and the knuckle will be sitting at the bottom right of the drive cog. The opposite end of the feeder bar hangs on an arm on the right side of the access and there should be 2 holes in the steel behind the arm and you will need to line those up as well. Once you have those three spots line up, you will just refit the feeder drive chain, and re-tension that and the timing chain which is accessed from the front. Test it by cycling by hand several times and then run the pto very slowly to check that everything is clearing fine.

I've always tripped the knotters and timed it so the leading edge of the plunger is one inch ahead of the tips of the needles as they enter the chamber. basically by the book, and I havn't had a timing related mishap.

It is important to keep the knotter drive chain adjusted needles get broken when it gets too much slack, Stan R is correct for timing

I tried vertical,kept hitting stop. Brother in-law suggested plunger arm fully extended. Still wouldn't cycle. Finally tried plunger in forward position. Lined up the notch with dots. Finally got it to cycle. I tripped knotter twice more to make sure it wasn't a fluke. I then engaged pto, kept fingers crossed, let it run a few minutes. No problems. I then fed it hay, tied , ran 8 more bales through, tied everyone.. That was a relief,didn't want to bust anything.

I stopped at the new holland dealer after work and picked up new shear bolts for knotter assembly. I checked mine, wasn't broke yet but didn't look right. Figured better change it before I have more problems.
