FAQ
Q1: How can I be sure this cylinder head (3811985) will fit my engine? A: This part is specifically designed for the Cummins K19 and KTA19 engine series. To confirm fitment 100%, please check the casting number on your existing cylinder head. If it matches 3811985 or a closely related K19 casting number, this part is the correct replacement. We also recommend verifying your engine’s serial number (ESN) with a Cummins dealer if you are unsure.
Q2: What does the installation process for a new cylinder head typically involve? A: Replacing a cylinder head is a complex mechanical task. It requires removing the rocker arms, pushrods, and head bolts. The cylinder block deck must be clean and flat. It is critical to use new head gaskets and follow the factory torque specifications and tightening sequence for the K19 engine. We recommend this job be performed by a qualified diesel mechanic with experience on Cummins engines.
Q3: Do you provide any documentation for customs clearance or quality verification? A: Yes. We provide a Machinery Test Report with the shipment to demonstrate the part’s quality. We can also arrange for a Video Outgoing Inspection before shipping. For international orders, we provide a Commercial Invoice and Packing List, and can assist with other required documentation to facilitate smooth customs clearance in your country.
