EM-7 ENGINE MECHANICAL (2JZ-GTE) - VALVE CLEARANCE EM0494 (b) Determine the replacement adjusting shim size according to the following Formula or Charts: • Using a micrometer, measure the thickness of the removed shim. • Calculate the thickness of a new shim so the valve clearance comes within specified value. T ........... Thickness of used shim A ........... Measured valve clearance N ........... Thickness of new shim Intake N = T + (A - 0.20 mm (0.008 in.)) Exhaust N = T + (A - 0.30 mm (0.012 in.)) • Select a new shim with a thickness as close as possible to the calculated values. HINT: Shims are available in 17 sizes in increments of 0.050 mm (0.0020 in.), from 2.500 mm (0.0984 in.) to 3.300 mm (0.1299 in.). SST (B) SST (A) P11926 (c) Install a new adjusting shim. • Place a new adjusting shim on the valve lifter, with imprinted numbers facing down. • Press down the valve lifter with SST (A), and remove SST (B). SST 09248-55040 (d) Recheck the valve clearance. Seal Packing P11777 9. REINSTALL NO.1 AND NO.2 CYLINDER HEAD COVERS (a) Remove any old packing (FIPG) material. (b) Apply seal packing to the cylinder head as shown in the illustration. Seal packing: Part No. 08826-00080 or equivalent (c) Install the gaskets to the No.1 and No.2 cylinder head covers. (d) Install the 12 seal washers to the bolts. (e) Install the No.2 cylinder head cover with the 6 bolts, 4 seal washers and 4 nuts.. Torque: 5.4 N·m (55 kgf·cm, 48 in.·lbf) (f) Install the No.1 cylinder head cover with the 6 bolts, 4 seal washers and 4 nuts.. Torque: 5.4 N·m (55 kgf·cm, 48 in.·lbf) (g) Connect the 2 PCV hoses to the cylinder head covers. (h) Install the bolt holding the VSV to the turbo outlet duct. (i) Connect the cruise control actuator cable to the cable bracket. 1997 SUPRA (RM502U) Author : Date : 1112
