2. "Cooler Out" pressure reading is taken with a 150

psi pressure gauge at right hand test port at back of air-oil

cooler. Reading should be 10 to 14 psi (69 to 96 kPalO,7

should be at operating temperature of 180 to 200 (82 to

filter housing, the clutch pressure should register 240 to

280 psi (1654 to 1930 kPa /16,9 to 19,6 kg /sq. cm). All

clutch pressures must be equal within 5 psi (35 kPa/0,4

kg/sq. cm). If clutch pressure varies in any one clutch

more than 5 psi, clutch requires repair.

"Cooler In" Pressure Test

"Converter In" pressure tested with a 150 psi

pressure gauge should register 40 to 90 psi (276 to 620

kPa/2,8 to 6,3 kg /sq. cm) at test port on pump valve
