FAQ

Q1: Is this cylinder head a complete assembly or a bare head? Does it include valves, springs, or seals?

This part is typically supplied as a bare cylinder head casting, machined and ready for assembly. It does not usually include internal components like valves, valve guides, springs, or seals unless specified in the listing. We recommend reusing your existing valvetrain components or purchasing a cylinder head gasket and valve seal kit separately for a complete rebuild.

Q2: How can I confirm that this 137-3693 head will fit my specific Caterpillar S4K engine?

While this part is designed for the S4K 3064 engine model, there may be variations (e.g., “A”, “B”, “C” series). To confirm fitment, please check the casting number on your old cylinder head. It should match 137-3693. Additionally, verify the number of bolt holes, the size of the water ports, and the location of the injector holes. If you are unsure, please send us a photo of your old head or engine serial number for verification.

Q3: What is the recommended installation procedure for a new cylinder head?

Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the engine block deck surface. 2) Using a new head gasket specifically for the S4K 3064. 3) Applying the correct tightening torque and sequence as specified in the Caterpillar service manual (typically a multi-step torque-to-yield procedure). 4) After installation and initial run-in, re-torquing the head bolts is often recommended to ensure a proper seal.
