Cylinder sleeve fit, flange height and piston fit each get their own procedure in this International Harvester D-188 service manual PDF, a 24-page engine reference (OEM ID GSS-1322F) that also lists the D-166. Special torque values for the cylinder head, main bearings, connecting rods and flywheel sit beside standard nut and bolt torque data, so you can match each fastener to its bolt type. The procedures cover valve lash set from the No. 1 and No. 4 piston positions, rear crankshaft oil seal installation, ram pressures for press fit sleeves and break-in for rebuilt diesels. Cranking compression should read 250 to 300 psi, and nozzle body bolts take 23 foot pounds. If the engine balancer is your job, exploded views lay out the assembly and a separate section locates the gear timing marks for installation. Buy it once and it stays yours. Bookmarks and a searchable text layer lead straight to the cylinder head tightening sequence and the ring gap and clearance checks.
