Remove the two camshaft housing retaining studs (8) and dowel (9). 6. Remove exhaust manifold adapter bolts (11) on Industrial engines only.7. Loosen water ferrule clamp (10) and remove ferrule assembly.8. Remove cylinder head retaining bolts and washers. Install three 3/8" - 16NC forged eyebolts in head assembly. Attach a hoist and remove the cylinder head assembly- weight 300 lbs. (136 kg). Always replace the gasket between spacer plate and cylinder block before reinstalling cylinder head assembly. See REMOVE SPACER PLATES.Install Left Front Cylinder Head Assembly
1. Clean the top surface of spacer plate and mating surface of cylinder head. Install new head gasket and seals (1). Be sure the gasket between spacer plate and cylinder block has been replaced before installing cylinder head assembly. Refer to REMOVE AND INSTALL SPACER PLATES. 2. Attach a hoist and position the cylinder head assembly on engine. Put 9S3264 Sealant Compound on the threads of the camshaft housing retaining studs (2). Install the camshaft housing retaining studs (2) and the dowel. Tighten the studs to 20 3 lb.ft. (2.77 .42 mkg).3. Coat the threads of the cylinder head bolts and exhaust manifold adapter retaining bolts with 9M3710 Anti-Seize Compound. Install the cylinder head bolts and washers. Tighten the bolts in following Step sequence: 1 Tighten all bolts in numerical order to 175 lb. ft. (24,2 mkg).2 Retighten all bolts in numerical order to 250 lb. ft. (34,6 mkg).3 Finally, retighten all bolts by hand in numerical order to 250 lb. ft. (34,6 mkg).4 Again tighten bolt (9) between the two heads to 250 10 lb.ft. (34.6 1.38 mkg). 4. Install a new gasket, and install exhaust manifold adapter retaining bolts on Industrial engines only. Install the water ferrule assembly (3). Tighten the bolt in the clamp for the water ferrule and seal to 30 5 lb.in. (34.56 5.76 cm.kg).
Do not tighten the bolt more than the specification. If the bolt is tightened more, the seal will be damaged.
5. Attach a hoist to water temperature regulator housing assembly. Position housing (4) on engine and install retaining bolts. Connect lower housing water lines. Connect right aftercooler water elbow to aftercooler housing. Install water bypass line. Install and connect oil lines to oil temperature sensing unit.6.
