[redroge]

has anyone any info on a mcquay compressor model mqc904-s 2cl its on a alr1000s chiller the problem is no oil pressure at all ,before i take the oil pump off i just wondered if there are any internal valves etc.

Hi mate from the oil pump side look towards the left and you,ll see a round plate with about (8) m12 bolts in it,take that off and on it is a oil pressure relief valve,and micro oil filter ,check them first ,because if the micro oil filter gets blocked it produces no pressure,any problems let me know and i,ll help more
