As title states, working on a new to me machine.  Been neglected something fierce.  Gotta do all bearings and some slides for plunger.  One bearing wasn't there, another had frozen and was wore half through.  Couple slides had bolts missing and were wore half through because they bowed up.  One knotter worked other didn't, bales left in chamber causing rust,broken springs on feeder tines, counter, twine fingers, 2 out of 5 hay dogs completely set up and needed torches to get out, etc etc etc. Anyways...


Noticed on plunger crank arm a rectangular place not painted with two holes.  Looked in parts manual and shows a stack of weights I believe.  Are these required or simply nice to have or what?  Will I notice any difference with them on or off?


Does anyone have a complete plunger repair kit available?


Where is the best place to buy parts for this?  Cost vs quality, etc.


Thank you in advance!

Bearings from Shoup. Rails from Esch Hay Equipment. Most anything else from NH.

Idk if it's the same but my 268 has a rubber block and a steel plate in those 2 bolt holes. Maybe for vibration? I couldn't tell you to be honest.

There are two rubber pads and the top steel plate.  They are there to absorb the shock if the needle safety latch is in the chamber when the crank arm comes around.  When the needles enter the chamber, the safety also enters the chamber.  If for some reason the needles do not exit the chamber, the crank arm padded plate will strike the safety latch and shear the flywheel shear bolt saving the needles.

An absorbing block.  Makes sense.  I can see on the safety latch for needles where it's been hit before.  Wonder why those pads are missing?  I feel dumb now that I looked at the parts picture but didn't chase down the numbers to see what they were called.  Thinking I probably ought to get them on there at least, now that I know what they're for.
