Pump
leaks. There are only 5 spots for a self-contained P/S pump
to leak. The front where the pump seals to the reservoir (o-ring), the back
where flow valve passes through the reservoir (o-ring), at the return line
(brazed) and the rear 2 mounting points (o-ring). If customer
reports a leak on a self-contained pump make sure they have pump bracket
mounting points tight and flow valve connection tight.
-
Pump noise or
groan. This is most commonly caused
by a restriction or air trapped in the system. Can also be caused by heat
buildup. (This would include a loss of assist)
-
No power assist after recent P/S system service. This
is most commonly caused by fluid contamination causing the pressure bypass
valve to stick open resulting in no pump pressure. To fix this remove the flow
valve and insure the pressure bypass valve moves freely in and out. This can
also be a large amount of air trapped in the system.
-
Hard steering
in both directions. This can result
from insufficient pump flow/pressure, low P/S fluid level, air trapped in
system and excessive heat build-up.
-
Foamy P/S
fluid. This is most often caused by
either air trapped in the system or a leak in the return line sucking in air.
-
P/S Reservoir
Cap Blows Off. This is most often caused by an air leak. Air
is sucked in to the P/S system compressed with the fluid and then expands when
it reaches the reservoir causing an unintended pressure build up in reservoir.
-
Excessive
response / Touchy Steering. This is generally caused by excessive pump pressure
we offer a pressure reduction kit #899001 that will allow the customer to
adjust the internal bypass pressure of the P/S pump. This is a very common
issue on street rods running a GM pump with a Mustang R&P.
REMOTE P/S PUMP TROUBLE SHOOTING:
-
No function
D.O.A. There is one main reason a remote style P/S pump would
be DOA. The pulley although called press-on IS NOT TO BE PRESSED ON.
The customer must use a PULLEY INSTALLATION TOOL. Failure to use
the proper installation tool can crack the pump housing and cause the pump to
be inoperable.
-
Pump
leaks. The pump itself, if not subjected to the above, won’t
leak. The most common manifestation of
leaks in a remote style system is from the P/S hoses. The customer assembles the hoses and this can
be a tricky process.
-
Pump noise or
groan. This is most commonly caused
by a restriction or air trapped in the system. This can also be caused by not
positioning the reservoir sufficiently above the P/S pump or an inadequate feed
line from the reservoir to the pump.
-
No power assist after recent P/S system service. This
is most commonly caused by fluid contamination causing the pressure bypass
valve to stick open resulting in no pump pressure. To fix this remove the flow
valve and insure the pressure bypass valve moves freely in and out. This can
also be a large amount of air trapped in the system.
