Conventional baler

[Deere 6430]

Bit of an open ended question but when do most people give a conventional baler a total overhaul such as plunger guides and bearings etc?

Most importantly do worn plungers give knotting issues?

If there is play in the plunger would you say that is fair wear and tear or time to get rid? No idea how many bales it has done as haven’t owned from new. It’s a John Deere 456 if that makes any difference.

We did our Claas Markant when we ran out of adjustment for the knife clearance, as for bearings if you have it in bits if In doubt throw it out!
Had dealer to sort a knotter problem and now it goes like a good un!
I would say that if the rest of it is in good order it’s worth sorting the plunger.

Not hard to change guides and rollers.

Makes a hell of a difference if you keep them adjusted properly too.

Used to fully overhaul at 3 years old doing 100k to 120k a season

I did my JD459 a couple of seasons ago- made a huge difference to the machine.

My twopenneth is the clean the thing properly before you start- the dust is terrible and gets everywhere. Make sure you can get the shoulder bolts- there are various sizes in there and JD only like supplying volume. Bearings are simple and straightforward to change. Watch the connection rod that goes from the pitman arm to the plunger. It's only a small piece of box section and often cracks where the bearing bolts to it.

Lastly, take your time when setting it up, especially the knife clearances. It helps to have a mate watching the plunger travel as you adjust as well.
