Make reference to CYLINDER LINER PROJECTION in Testing and Adjusting for the complete procedure.1. Install tooling as shown. Tighten bolts (1) evenly in four steps: 1st step ... 5 lb. ft.(7 N m)2nd step ... 15 lb. ft.(20 N m)3rd step ... 25 lb. ft.(35 N m)4th step ... 50 lb. ft.(70 N m)2. Measure cylinder liner projection with dial indicator (7) clamped in 1P2402 Gauge Body (6) as shown. Measure at four places around each cylinder liner near the clamped area. Cylinder liner projection measurement for any cylinder liner must be ... .0020 to .0056 in.(0.051 to 0.142 mm)Maximum permissible difference between all four measurements ... .002 in.(0.05 mm)Maximum permissible difference between average projection of any two cylinders next to each other ... .002 in.(0.05 mm)Maximum permissible difference between average projection of all cylinder liners under one cylinder head ... .004 in.(0.10 mm) If liner projection is not correct, turn the liner to a new position within the bore. If projection can not be corrected this way, move the liner to a different bore. If the projection can not be corrected this way, make reference to Special Instruction, Form No. FM055228 for complete instructions on the use of 8S3140 Counterboring Tool Arrangement.(1) Bolts [5/8" NC, 5.5 in.
