Hi guys,

we are experiencing early break downs on some of our Frick compressors.
I opened them and overhauled few of them, the reason of the break down is coming from the balance piston on the male thrust bearing, it is getting stuck in pushed position.

I was wondering if we could connect oil pressure on the balance piston, there is connections available on the housing but it is not used.

Units are working with R507, I can send pictures if people are familiar with these compressors.

Regards
