Install a new gasket and spacer plate (5) on the cylinder block.
Install the cylinder liners in the cylinder block without seals or without bands.
Hold the spacer plate and the cylinder liner in position according to the following procedure:
Install four 0S-1575 Bolt (4) and washers around each cylinder liner. Tighten the bolts evenly to a torque of 95 N m (70 lb ft).Ensure that the surface of the cylinder liner is clean.
Install the following items:
The 8B-7548 Push-Puller Tool Group (6)
The 3H-0465 Push-Puller Plate (1)
Two 8F-6123 Bolts Ensure that the 8B-7548 Push-Puller Tool Group is in the proper position at the center of the cylinder liner.
Check the distance from the edges to the bottom of the 8B-7548 Push-Puller Tool Group (6) to the top of the spacer plate. The distance on each end of the 8B-7548 Push-Puller Tool Group must be equal.
Use the 8T-0455 Liner Projection Tool Group to measure the cylinder liner projection.
Mount the dial indicator (2) in the 1P-2402 Gauge Body (3). Use the back of the 1P-5507 Gauge Block to zero the dial indicator (2).
The cylinder liner projection must be 0.033 to 0.175 mm (0.0013 to 0.0069 inch). Make the measurement to the outer flange of the cylinder liner. Do not make the measurement to the inner ring. The maximum difference between the high measurements and the low measurements that is made at four places around each cylinder liner should be 0.05 mm (.002 inch).Note: If the cylinder liner projection changes around the cylinder liner, turn the cylinder liner to a new position within the bore. If the cylinder liner projection is not within specifications, move the cylinder liner to a different bore. Inspect the top face of the cylinder block.Note: When the cylinder liner projection is correct, mark the cylinder liner and the spacer plate. When the seals and the band are installed, the cylinder liner can be installed in the correct position.
