This procedure outlines the repair for a 3600 series cylinder head used in a residual fuel application. All information needed to complete the repair of the cylinder head is included in this document with the exception of the "Guideline for Reusable Parts and Salvage Operations." Further references can be made to the 3600 series service manuals.References

Before starting the rebuild procedure on a 3600 series cylinder head, it is important to obtain the correct tooling and equipment. The various tooling listed will accomplish the outlined task. Rebuild Procedure Disassemble Cylinder Head 1100-015
1. Bolt cylinder head on the 8T-2826 Fixture and 1U-9352 Engine Stand.2. Inspection: Inspect the cylinder head for external damage such as large cracks in the combustion surface between the valve seat pockets and the injector hole, pitting and erosion of the combustion surface or damaged caused by separated valve heads. This type of damage requires replacement of the cylinder head. 3. Clean the combustion surface of the cylinder head using the 1U-5780 Angle Grinder with the 5P-9709 Metal Reconditioning Disk and the 5P-9718 Disk Pad. The combustion surface should be cleaned to a bare metal finish. When cleaning the combustion surface take care to ensure that no metal is removed from the cylinder head casting.4. Inspection: Measure the thickness of the cylinder head casting using the outside micrometer. The minimum allowable thickness of the cylinder head casting is 279.0 mm (10.98 in). If the cylinder head does not meet specifications, or has pitting on the combustion surface that will require machining below tolerance, the cylinder head must be replaced. 5. To locate the sealing surface area, place the spacer plate on the combustion surface aligned with the cylinder head stud holes. Using a permanent marker, draw a line around the inside diameter of the spacer plate. 6. With the spacer plate still on the combustion surface, place the sealing ring on the combustion surface and draw a line around the inside diameter. The area between the two lines, after the spacer plate and sealing ring have been removed, is the combustion sealing ring area. The inner diameter of the combustion sealing surface is 330.0 1.0 mm (12.99 .04 in), the outer diameter of the combustion sealing surface is 380.0 1.0 mm (14.96 .04 in). If the engine does not have a spacer plate, create a template with the above dimensions that aligns with the injector hole in the cylinder head. 7. Inspection: Measure the flatness of the combustion surface and the combustion sealing ring surface with the straight edge and the 8H-8581 Feeler Gauges. The combustion surface flatness must not exceed a maximum of 0.10 mm per 100.00 mm (0.004 in per 4.000 in) length except within the combustion sealing ring area. Within the combustion sealing ring area the surface flatness must not exceed
