Hi. I've just purchased an old O&K RH6 LC excavator from 1987. I've found the manual for the machine here on this great forum (thanks for that).
I have a problem that I can't tension the right axel (belt track). The valve where I need to pump in high pressure grease to tension the belt/axle is just fully open and I can't tension the valve. See attached pictures. I can't pull out position 30 but I can freely turn it by my hands. Maybe the thread inside is broken?

Anybody who can send me in the right direction?
Thanks in advance
