1. Remove the air intake duct and air cleaner housing, and connect the oil pressure gauge to the 2nd clutch pressure inspection port (C). Then temporarily install the air cleaner housing and air intake duct.

1. Start the engine, and shift into the M position.

1. Shift to 1st gear, and measure the 1st clutch pressure at the 1st clutch pressure inspection port (B) while holding engine speed at 2,000 rpm (min −1 ).

1. Shift up to 2nd gear, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port (C) while holding engine speed at 2,000 rpm (min −1 ).

   Standard | Service Limit
   1st clutch (B) 2nd clutch (C) | 890−970 kPa (9.1−9.9 kgf/cm 2 , 130−140 psi) | 840 kPa (8.6 kgf/cm 2 , 120 psi)

   K24A3 engine model:

   Pressure | Fluid Pressure
   --- | ---
   Standard | Service Limit
   1st clutch (B) 2nd clutch (C) | 917−995.4 kPa (9.35−10.15 kgf/cm 2 , 133−144.3 psi) | 868 kPa (8.85 kgf/cm 2 , 126 psi)

1. Turn the engine off, then disconnect the oil pressure gauges from the 1st clutch pressure and 2nd clutch pressure inspection ports.

1. Install the sealing bolts in the 1st clutch pressure and 2nd clutch pressure inspection ports with new sealing washers, and tighten the bolts to 18 N·m (1.8 kgf·m, 13 lbf·ft). Do not reuse old sealing washers.
