Specification Highlights:

Engine compression ratios for the 4Y model are documented at 8.8, while the 1DZ-II diesel engine is specified at 21.5. Clutch operating pressure for the torque converter is set to 1108 kPa (161 psi) at 2000 rpm. The 1DZ-II injection timing and compression data are central to maintaining the 151.71 cubic inch engine. Lubrication requirements include GM Dexron II for the transmission, while the differential requires SAE85W-90 hypoid gear oil.

Standard bolt torque values are provided in a comprehensive reference table categorizing hardware by class and diameter. Cylinder head bolt torque values are specified in the 4Y and 1DZ-II engine sections to facilitate correct reassembly. Hydraulic oil volumes for the V mast are calculated at 29–38 liters depending on the model series.
