Hello,
i am having problems with the following compressor howden mk1 wrv163, we had it shiped from an italian company that did maintenance to it. We have installed it but we are having problems when we turn it on, its making an abnormal noise. We have had to change one of the graphite pieces in the front already because we did not realize that the oil pump had very little pressure and i think the graphite broke because of too much friction and lack of oil. changed that pieace and its still giving me the same problme. if anyone has a diagram or an instrucion manual that would be highly appreciated.

giorgio
