FAQ

Q1: Is this cylinder head a direct bolt-on replacement for my Perkins 403D-15 engine?
A: Yes, the part number 111011050 is the OEM replacement for the Perkins 403D-15 and 403D-15G engines. It comes with valve guides and seats pre-installed. However, you must transfer your existing injectors, glow plugs, and other external components from your old head. We recommend using a new head gasket set during installation.

Q2: What is the difference between this 111011050 head and the 111011051 version?
A: While both are for the 403D-15 engine family, the 111011050 is the standard production part. The 111011051 may be a service replacement or a variant for a specific application (e.g., different valve stem seal type). We strongly advise checking the casting number on your current cylinder head to confirm the exact match. If you have the 111011051, please contact us to verify compatibility.

Q3: Do I need to replace the cylinder head bolts and gasket when installing this new head?
A: Yes, it is a critical best practice to always install a new cylinder head gasket set and new head bolts (or studs) when replacing the cylinder head. The original bolts can stretch and lose their clamping force, leading to gasket failure. We recommend using a genuine Perkins or high-quality aftermarket gasket set for optimal performance and longevity.
