Maintenance; Removing And Cleaning The Inlet Valve; Removing And Cleaning The Outlet Valve - Titan 0508074A Owner's Manual

Maintenance

Follow these procedures when encountering problems indicated in
the troubleshooting section.

removing and cleaning the Inlet Valve

1. Perform the Pressure Relief Procedure, turn off and unplug the
unit.
2. Remove the inlet valve assembly using a 27 millimeter socket
or box end wrench.
3. Test movement of the valve by pushing on it from the open
end of the valve housing with a screwdriver or the eraser end
of a pencil. It should move about 1/16 of an inch. If it does
not move, it should be cleaned or replaced.
NOTE: The inlet valve must be oiled
after every job. This will reduce
or eliminate priming problems
the next time the unit is used
as well as extend the life of the
valve.
4. Thoroughly clean the valve assembly with
water or the appropriate solvent. Use a small brush.
5. If the valve has been properly cleaned and water drips out of
the bottom, the valve is worn and needs to be replaced. A
properly seated valve filled with water and held vertically will
not drip.
6. Install a new or cleaned valve in the pump block and then fill
the valve with light oil or solvent.

removing and cleaning the Outlet Valve

It may be necessary to remove and clean the outlet valve or to
replace parts inside the valve worn out through normal use.
1. Remove the outlet valve nut with a wrench.
2. Remove and clean the ball stop and small spring inside the
valve using a wire hook or tweezers. Replace the spring if it is
broken or worn.
NOTE: This spring is manufactured to a very specific
tension. Do not stretch the spring. Do not put in
an unauthorized substitute. See the paint pump
assembly parts diagram for the proper replacement
part number.
3. Remove the seat and ball assembly.
4. Clean all parts thoroughly. If the ball or seat show any sign of
wear or damage, replace them with new parts. This carbide
ball must seal tightly against its seat for the valve to function
properly.
5. Cover all parts with a thin coat of light oil before reassembling.
6. Drop in the valve ball.
7. Insert the protector and spring and replace the valve body.
Be sure that the O-ring is positioned properly and that the
tongue on the cap fits inside the spring.
8. Tighten the valve body securely with an adjustable wrench.
Do not over-tighten.
NOTE: wear on the ball is almost impossible to detect
visually. To test for a worn outlet valve assembly,
turn the pressure control knob clockwise to its
highest setting and run water only through the
pump for 10 to 15 minutes without triggering the
gun.
If the valve is defective, the end cap will get very hot
to the touch. If it is functioning properly, it will stay
approximately the same temperature as the water
running through it.
