2.4.3 O-rings and Lubrication
O-rings and seals should be replaced anytime an actuator is disassembled. Lubricate with a substance that is compat-
ible with Buna N seals.
2.5 Subassembly Removal and Remounting Procedures
This manual divides each MX actuator subassembly into a Removal and Remounting procedure. Use the following
procedures to remove subassemblies for inspection, repair or replacement. Some subassemblies require prior subas-
sembly removal before allowing the desired subassembly removal. Note the First Remove instructions at the beginning
of each subassembly removal procedure. Remove these subassemblies first, then remove the desired subassembly
according to the instructions. Once removed, evaluate subassembly components to determine requirement for a new
subassembly. If a new subassembly is required, see Section 2.6, How to Order Replace-ment Subassemblies. Once
components have been identified and replaced, remount following the appropriate Re-mount-ing procedures.
