PROBLEM
A. Hydraulic motor stalls at
bottom or top of stroke; low
or intermittent uid pump
pressure; unusual stroke speed;
high heat of the hydraulic oil
temperature (above 200ºF,
[93ºC]).
CAUSE
1. Low hydraulic oil level.
2. Pressure control setting too low.
3. Hydraulic belt or pulley failure.
4. Hydraulic piston failure.
5. Bound or broken uid section piston.
6. Hydraulic piston rod seal failure
7. Hydraulic piston head seal failure
8. Other
SOLUTION
1. Check oil level. Fill if necessary. If the oil level is full,
check the controller.
2. Make sure the pressure control knob is turned up
enough to cycle the motor. If the pressure control
setting is okay, then check the belt and pulleys.
3. Make sure the key is present in the output shaft of
the engine/electric motor and the input shaft of the
hydraulic pump. Make sure the belt is not broken and
has adequate tension. If belt and pulleys are okay,
please contact a Titan Authorized Service Center.
4. Visually check hydraulic piston rod for breaks. If a
broken hydraulic piston rod is apparent then remove/
replace hydraulic piston. Depending on where the
break occurred the piston coupler may also need to be
replaced. Please visit a Titan Authorized Service Center
if assistance is necessary. If hydraulic piston is okay then
check for bound/broken uid section piston
5. To check for a bound/broken uid section piston
de-couple the hydraulic piston from the paint piston
by removing the dowel pin. Power up the unit. If the
hydraulic motor cycles when the hydraulic piston is de-
coupled from the paint piston then the problem is most
likely in the uid section. Please visit a Titan Authorized
Service Center if assistance is necessary. If the hydraulic
motor still does not cycle then check the hydraulic
piston rod seal.
6. Remove the hydraulic piston rod seal plug which
contains the rod seal, O-ring, and rod wear ring. Check
for damage and replace rod seal, O-ring, or rod wear ring
if necessary. If rod seal, O-ring, and rod wear ring are
okay then check the hydraulic piston head seal.
7. Remove the hydraulic piston and inspect/replace the
piston head seal and piston head wear ring as needed.
During this process check the cylinder bore for damage
or uneven wear marks. If the cylinder bore is damaged
then replace pump block along with piston head seal
and piston head wear ring.
8. If problems persist please see a Titan Certied Service
Center.
