Control Manifold (Pilot Oil) - Disassemble

Usage:

321C DAX

Disassembly Procedure

Start By:

  1. Remove the control manifold. Refer to Disassembly and Assembly, "Control Manifold (Pilot Oil) - Remove".


NOTICE

Keep all parts clean from contaminants.

Contamination of the hydraulic system with foreign material will reduce the service life of the hydraulic system components.

To prevent contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. Cover any disassembled components and clean them properly before assembly.

Clean the hydraulic system properly after any major component exchange or especially after a component failure, to remove any contamination.


Note: Cleanliness is an important factor. Before the disassembly procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
