The illustration and the chart identify the components that are required. An 8T-0455 Liner Projection Tool Group is also required.
The components should be assembled in the order that is shown in Illustration 1. 7K-1977 Washer must contact the top surface of the fire ring. The 7K-1977 Washer (4) is made of a cotton fabric that is impregnated with resin. The washer will not damage the sealing surface of the cylinder block.Note: Inspect the washer before measuring the liner projection. Replace the washer if the washer is worn or damaged.
Tighten bolts (1) evenly according to the following procedure:First tighten each bolt to the following torque. ... 14 N m (10 lb ft)Tighten each bolt again to the following torque. ... 14 N m (10 lb ft)

(5) Dial indicator
(6) Bolt
(7) Gauge body
(8) Gauge
Loosen bolt (6) until dial indicator (5) can be moved. Place gauge body (7) and dial indicator (5) on the long side of gauge (8).
Slide dial indicator (5) into the correct position. When the point of the dial indicator contacts gauge (8), the dial indicator is in the correct position. Slide the dial indicator until the needle of the gauge makes a quarter of a revolution clockwise. The needle should be in a vertical position. Tighten bolt (6) and zero the dial indicator.
Place gauge body (7) on the spacer plate for the cylinder block. The indicator point should be on the liner flange. Read the dial indicator to find the amount of liner projection. Check the projection at four locations (every 90 degrees) around each cylinder liner.

Specifications
Liner projection −0.055 mm (−0.00217 inch) to 0.055 mm (0.00217 inch)
Maximum variation in each liner 0.050 mm (0.0020 inch)
Maximum average variation between adjacent liners 0.080 mm (0.0031 inch)
Maximum variation between all six liners 0.102 mm (0.0040 inch)
If a liner does not meet the recommended cylinder liner projection specification, check the following parts:
The liner flange should be 130.000 0.025 mm (5.1181 0.0010 inch).
The depth of the cylinder block bore should be 130.000 0.030 mm (5.1181 0.0012 inch).If the liner flange does not meet the specifications, replace the liner. Recheck the liner projection measurements. If the depth of the cylinder block bore does not meet the spec, replace the cylinder block. Again, recheck the liner projection measurements.
