NH 273 timing is this correct????

Blew my needles when my knitter chain broke my brake didnt come outI picked up a parts baler and changed both needles and the yoke.now I would like to be sure I have my timing correct before I try it out. Here is some pics and a video of how it is.
Thanks Guys if anyone has any info





The last photo is just when the needles are entering the bale chamber

Shady,

No pictures or video showed up when I accessed your note. But, let me say this, it is essential that you get a service manual before you fire that
thing up. Not only does the timing have to be set, the angle of the needles also have to be set, the knotter brake needs to be checked, and the
adjustment on the bar that protects the needles from being broken if the timing isn't right also needs to be checked.

You might already know all of those things, but just a reminder.

Thanks yes I do have a manual and I also cant get my pics to upload for some reason

Not always, but in many cases new users have to have 5 or more posts on record before the site lets them post pictures (or links), due to site spam filters. Another option is to go down to the Site Comments Forum and ask YT Support for permission to post prior to that. You can try going down to the Test Forum and making several posts there to get your post count up, trying to attach your pictures to each post. That may work after you make several posts. Then make your post here again. It may not work immediately after you get past the 5 posts, if not, you might try logging out and back in at that point. There is a size limit as well, I think it is a total of 7mb per post (be it one picture or the total of several). Some pictures (often taken with phones), are too large and have to be reduced before they will post.

Ok Thanks

Not really in time. Trip wheel roll plunger direction of rotation when needles start to enter chamber the plunger extensions should meet at same time. The dots are only a starting point. Should be a diagrham
on feeder door inside.

You have one more set of dots to look over, the plunger arm is to be vertical at the dots alongside the plunger chamber towards
the front of the baler. You said you have a manual, so probably just did not get that picture to load. Seems like the dots on the
knotter assembly were at the top(12'o clock) rather than what looks like 3 o'clock. Thats what I recall from timing mine, my
recall could be wrong. good luck with your baler. gobble

As mentioned, need plunger arm vertically on its dots.

Its is very close but not meeting exactly should the plunger still be going forward when the needles enter the chamber are the voids in the plunger for this I assume???

the second pic is the plunger arm and its hard to see from the pic but it is vertical and between the 2 chisel marks also probably again from the bad pics but the dots on the knotter are about 3 oclock I think maybe Im pretty close but still off a few teeth
Thanks for the help

The chisel marks and dots are correct for the plunger and knotter clutch but there are other adjustments to go through. Go through your manual in order and check and
reset all the adjustments. It's confusing at first, took me a while to catch on. From your pictures it looks as though your needle tips are a little higher that they
should be.

Is that a hole rotted through the bale chamber wall that I see in the picture of the needles and plunger?

And it still makes a bale?

The resilience of these old balers amazes me.

I think that one of the reasons that the big equipment manufacturers had such a recession in the 80's is that they were victims of their own success. Their engineers were designing equipment that could last a century; while their marketing and finance people were assuming that farmers would buy new stuff every five years...

This brings up something that I've always wondered about.

Needle wear? Do the needles wear down? Seems as though the tip would wear from running up through the hay (although, the plunger voids protect it, mostly)... and the eye-hole would wear from twine running through it.

I wonder if some of the timing assumptions assume new needles, with new tips and eye-holes. With that in mind, I wonder what the REAL figure of merit..i.e. the point to be "timed" is. It would seem that it would be the position of the point where the twine comes through the eye-hole, with respect to the bale chamber floor?

Anyway, this is all details... I'm sure that it's fine to just look at the tips of the needles.

The plunger should be coming forward as the needles come up into the chamber.

As the needles rise through the chamber, the plunger pushes the hay that will become the last slab of the bale, into the bale. This clears the way for the needles to come up into the "voids" (as you call them) or slots in the plunger, in order to get the twine onto the end of the bale being formed.
