Dry cleaning solvent (P-D-680, Type III) is used to clean parts and is potentially
dangerous to personnel and property. Extinguish all smoking materials and do not
allow sparks or open flames near the work area. Use skin and eye protection and
work in a well-ventilated area. Flash point of dry cleaning solvent is 200F (93C).
Clean filter housing with wiping rags. Clean all other components with dry cleaning solvent.
Inspect filter assembly for cracked or broken sight gage, stripped threads, deformed preformed packing grooves,
nicks, cracks, dents, or evidence of leakage. Replace defective components as required.
If hydraulic filter was not disassembled during removal, proceed to step 2. If filter was disassembled during
removal, proceed as follows:
a. Install new filter element (7) into filter element housing (5). Apply a thin coat of petroleum jelly onto preformed
packing (8). Install preformed packing (8) onto filter block (6).
b. Install filter element housing (5), with filter element (7) and preformed packing (8) attached, to filter block (6).
c. Using a 1-1/4-inch wrench, tighten filter element housing (5) onto filter block (6).
Remove caps/plugs and apply petroleum jelly to two preformed packings (14) and install packings (14) onto two
straight pipe-to-tube adapters (10).
Install filter assembly (11) onto hydraulic control module (4) and secure with two lockwashers (13) and bolts (12).
Apply pipe sealant compound to the all male threads of hydraulic pipe threads,
using only enough compound to coat the threads. Do not allow compound to
enter a component/fitting or the compound may restrict fluid passages and
damage to equipment or equipment failure may result.
Remove caps/plugs and apply pipe sealant to male pipe threads of two straight adapters (10).
Remove caps/plugs from two hydraulic tubes (9) and reconnect two tubes to two straight pipe-to-tube adapters
Using two people, refer to step 7 of element change and aline and install lower panel, with door panel attached,
onto hydraulic control module (4).
