Clean Breather Plug

The solvents listed in this section may ignite if used in flushing. Use them only for external cleaning.

Remove and clean breather plug with compatible sol- vent. See materials of construction info in Technical Data, page 55. The breather plug is part of the solenoid manifold assembly (30). See FIG. 19. Use N-Methylpyr- rolidone (NMP), Dynasolve CU-6, Dzolv, or an equiva- lent to soften cured material. Applying a light coat of lubricant will make future cleaning easier. Torque breather plug to 30-40 in-lb (3.89-4.82 N•m).
