8.5.6 Minimum Pressure Valve Maintenance
The minimum pressure valve should be inspected when replacing the oil
separator element. Use the following procedure when servicing the minimum
pressure valve (refer Figure 15 - Minimum Pressure Valve Assembly):
1. Remove the cap (Item 14) by unscrewing it from the housing. Care
must be taken as internal assembly spring forces exist.
2. Lift the cap clear and remove the piston, spring and plunger / seat
assembly (Items 2 - 13).
3. Inspect the condition of the piston o-ring (Item 9) and replace if
necessary.
4. Check the condition of the Teflon disk (Item 5) and valve seat (Item 6),
and lap if necessary.
5. Reassemble in the reverse order, taking care to lubricate all surfaces
with High Temperature grease.
