CYLINDER BLOCK ASSEMBLY
HINT:
wThoroughly clean all parts to be assembled.
wBefore installing the parts, apply new engine oil to all
sliding and rotating surfaces.
wReplace all gaskets, O±rings and oil seals with new
parts.
NOTICE: Apply a generous amount of oil on the sliding surface
of the bearing, and not on the back of it or on the surface to
which it is installed.
1. 2JZ±GTE:
INSTALL OIL NOZZLES (WITH RELIEF VALVES)
Using a 5 mm hexagon wrench, install the oil nozzle with the
bolt. Install the 6 oil nozzles.
Torque: 8.8 NVm (90 kgfVcm, 78 in.Vlbf)
2. INSTALL MAIN BEARINGS
HINT:
wMain bearings come in widths of 20.0 mm (0.787 in.) and
23.0 mm (0.906 in.). Install the 23.0 mm bearings in the
No.1 cylinder block journal position with the main
bearing cap. Install the 20.0 mm bearings in the other
positions.
wUpper bearings have an oil groove and oil holes; lower
bearings do not.
(a) Align the bearing claw with the claw groove of the main
bearing cap or cylinder block.
NOTICE: Install the bearing with the oil hole in the cylinder
block.
(b) Install the bearings in the cylinder block and main bearing
caps.
