Clutch Pressure Test
NOTE:
Check clutch pressure at each clutch pressure tap on transaxle. See Fig 1.
- With engine off, remove pressure tap plug from appropriate clutch pressure tap on transaxle. See Fig 1. Attach pressure gauge to appropriate pressure tap. Tighten hose fitting to 13 ft. lbs. (18 N.m).
- Start and operate engine at 2000 RPM. Note clutch pressure reading with gearshift lever in appropriate position. See HYDRAULIC PRESSURE TEST SPECIFICATIONS table.
- Ensure clutch pressure is within specification. If clutch pressure is not within specification, see HYDRAULIC PRESSURE TEST TROUBLE SHOOTING table. Shut engine off.
