Checking the protrusion of the pistons with the cylinder head removed (Range Rover 3)

1. The top plane of the block of cylinders and the bottom of pistons should be pure.



2. Fix the dial indicator in the LRT-12-181 rack and install it on the cylinder block.

3. Expose "zero" indicator.



4. Place an indicator on the piston crown and measure the piston protrusion at two points as shown. By rotating the crankshaft, set the piston to the position corresponding to T.M.T. Record all measured piston protrusions and repeat the procedure for all pistons.



5. The largest piston protrusion determines the required thickness of the cylinder head gasket.

6. If the protrusion of the piston is from 0.92 to 1.03 mm, then a gasket with two notches must be installed.

7. If the protrusion of the piston exceeds 1.03 mm, then a gasket with three notches must be installed.
