Zerk sizes/thread for 4310?

[alternety]

I bought a used 4310 (about 10 years old I think). I have tried to lube it and 2 out of 2 zerks won't take grease. I am thinking I should just go through and replace them all. I have found at least on that is broken.

Can anyone tell me the size and thread on the zerks on the 4310 and 430 loader?

You could take out one of the zerks to the dealer or tractor supply. I bought a set of sae and metric tread kits for my equipement.

It is a 60 mile trip to ask; a lot simpler to order them online. This is the only thing I need zerks for. I don't need more kinds than I the tractor and attachments need.
