There are two intake screens in the deoiler housing of the vacuum pump
(intake and back-suction). The intake screens need to be checked for
contamination and cleaned.
• Undo banjo bolt (1) on each side of the deoiler housing and take it out of
the opening together with sealing ring (2) and intake screen (3).
• Clean the intake screens by blowing them out. If they are severely
contaminated, replace them.
• When assembling, ensure that second sealing ring (4) is fitted between
the housing and the connection.
• Fit the blow-out cover and the front cover of the deoiler housing with a
new seal each.
• Fill the oil reservoir with oil through filler neck (1) to at least half way up
sight glass (2).
