grease fittings. button heads

[hugo]

hi,

i am having problems with my rollers. I just want to put new grease in it.
I heard that they usually use button head fittings.
Now, how do i get them out? I like te repleace them for new ones. is there a special tool or way to do this?

All i see is a rusty and overpainted square hole.




its a 1965 jd 350 bulldozer. 5 roller

thanks

Those are sealed rollers, just take the plug out and add oil until it runs out.

Hi,

Because 3 rollers on te left side are leaking i have decided to put in grease.

I have 5 rollers done. One oil plug didnt came loose so i drilled and taped thread into it.



For the other 4, i have found some nice grease fittings. i hope it works.
