I would be very grateful if someone could help me out on a couple of dilemas that I have.
Two seperate Bock AM5 compressors have started leaking on the shaft seal, both systems are around 5 years old and never leaked on the shaft seals before , seems strange both have failed around the same time.
Could it be a coincidence?
Also, has anyone any tips on how to change the shaft seals on these particular units, have already pumped down and closed service valve's etc, but need some advice on the mechanical side of these Bock semi hermetic units?
Cheers Gareth.
