PRESSURE AND OIL FLOW CHECKS
Whenever improper performance is evident the following basic pressure and oil flow checks should be
performed and recorded. It is also recommended that these checks be taken periodically as a preventative main-
tenance measure. Doing so will permit possible detection of difficulties in advance of actual breakdown, thus
permitting scheduling of repair operation. Likewise, repair of minor difficulties can be made at considerably less
cost and down-time than when delayed until major and complete breakdowns occur.
Analyzing the results of these checks by comparison with specifications and with each other will indicate in
most cases the basic item or assembly in the system as the source of difficulty. Further checking of that assembly
will permit isolation of the specific cause of trouble.
(SEE PLUMBING AND CHECK POINT DIAGRAM)
OIL PRESSURE AT CONVERTER OUT PORT.
Install hydraulic pressure gauge at PRESSURE connection on Converter Regulator Valve or at CONVERTER
OUT pressure tap. (All models do not have pressure regulating valves.) Check and record oil pressure at 2000
RPM and at maximum speed (engine at full throttle) (see instructions on Stalling Converter previously listed).

If a flow meter is available, install in line between converter charging pump and oil filters. Plow meter must
be able to withstand 300 p.s.i. [21,0 kg/cm].
Disconnect hose between pump and filter at filter end and using suitable fittings connect to pressure port
of tester. Install hose between filter and tester, connecting same to reservoir port of tester.
DO NOT USE TESTER LOAD VALVE AT ANY TIME DURING TEST. When taking flow reading, all readings
should be taken on the first (left) half of flow gauge. Whenever the needle shows on the right half of gauge,
correct by switching to higher scale.
If a flow meter is not available for checking converter pump output, proceed with manual transmission and
converter checks. If the converter shows leakage within specifications and clutch pressures (180 to 220 p.s.i.)
[12,7-15,4 kg/cm2] are all equal within 5 p.s.i. [0,4 kg/cm] refer to paragraph on Low Converter Charging
Pump Output.
PUMPS ARE RATED AT 2000 RPM-Refer to Vehicle Manufacture Manual for specific pump output.

Pump output listed applies to a new pump in each `case. A 20% tolerance below this figure is permissible;
however, if pump output is more than 20% below specification the pump must be replaced and not rebuilt.
