The mounting holes in the cylinder head at location (A), used for a lifting eye bracket (or other brackets) may be a different size than the original head; therefore, rework and extra parts may be needed. Cylinder heads on earlier engines had bracket mounting holes with 3/8"-16-2B threads. Later cylinder heads had bracket mounting holes with 1/2"-13-2B threads. 1 If a cylinder head of the earlier type is replacing a later cylinder head, the replacement cylinder head will have 3/8"-16-2B threads in the mounting holes. Install the bracket with S1594 Bolts and 5M2894 Washers.2 If a cylinder head of the later type is replacing an earlier cylinder head, the holes in the lifting eye bracket (or other brackets) must be enlarged to 13.0 mm Ø (0.53" Ø). Use 6H1717 Bolts and 5P8245 Washers to install the lifting eye bracket on the replacement cylinder head.1100, 3100, 3208 Engines
