Disassembly to be carried out in order. As a result of a variety of hydraulic and pressure ring composition, when the pressure ring cylinder structure and size of each phase unscrew, the loop in the same, the disassembly order is also slightly different. General should, then remove the cylinder head, rod. 

Clean the environment in the removal of the hydraulic lock on the card within the card key or snap ring To use special tools, prohibit the use of flat shovel; for flanged end caps must be screwed out, not allowed to hammer or cause further Hard pry. Piston and piston rod difficult with the piston rod installed the same before the cylinder, should make the hydraulic pressure to withdraw, can not be forced to play, should first identify the demolition.

Before and after unloading to try to create conditions to prevent the electric pump parts are contaminated by the surrounding dust and impurities. Example cloth or other work-like support ring, the role of cloth cover.

It is noteworthy that the high-pressure electric pump to be carefully checked after disassembly to determine which parts can continue to use, which parts can be repaired and then let go of the two-cylinder oil tank, which parts must be replaced. Parts must be carefully cleaned before assembly.
