Engine unit 2AD-FHV Replacement 1. REPLACE CONNECTING ROD SMALL END BUSH Using SST and a press, push out the bush. Using a round file, lightly file off any roughness from the small end of the connecting rod. Attach a new bush to SST with the ball of SST inside the oil hole of the bush.

INSPECT CHAIN SUB-ASSEMBLY Using spring scale, pull the chain with a force of 147 N (15 kgf, 33 lbf) as shown in the illustration. Using vernier calipers, measure the length of 16 links. Maximum chain elongation: 144.3 mm (5.681 in.) If the elongation is greater than the maximum, replace the chain. NOTICE: Perform the same measurement by pulling at random in 3 or more places to obtain an average.

CHECK DIESEL THROTTLE BODY ASSEMBLY Check for the throttle control motor operating sounds.   Turn the ignition switch on (IG). When pressing the accelerator pedal, check for the operating sound of the motor. Make sure that no friction noises emit from the motor. If friction noise exists, replace the throttle body. Check the throttle position sensor.
