Got an LT pack at a store and having problems with oil on one of the comps on it.
There are 5 comps on the pack each with liquid inject and oil is fed from a sep into the res then into seperate oil floats/regulators. The problem is that compressor 4 just seems to keep filling up with oil regardless of how the float is set. Have replaced the comp float which has had no effect. The sep float valve has been dropped and cleaned as this was sticking shut originally. Oil pump on comp is ok got about 40 psi diff. Checked diff valve on oil resevoir to suction 20 psi diff. Level on resevoir is just above bottom sight glass just over a third full.
Its a strange one as other 4 comps seem to control oil level fine. To get the level right and not risk the comp hydrolicing have basically had to leave oil in the system at a minimum anymore and it just fills this comp 4.
Any ideas would be most appreciated.
Ta!
