FAQ

Q1: How do I confirm this Cam Bush (7M4046/8N4110) fits my specific engine?
A: This part is specifically designed for the Caterpillar 3306 engine model. To confirm fitment, locate the existing part number on your old bushing or consult your engine’s parts manual. If your engine is a 3306 and the old part number matches 7M4046 or 8N4110, this is the correct replacement. We recommend verifying with your engine serial number (ESN) if possible.

Q2: What is the correct installation procedure for a camshaft bushing?
A: Installation requires careful alignment and proper tooling. The bushing must be pressed into the cylinder block bore using a driver tool that matches the outer diameter of the bushing. Ensure the oil hole in the bushing aligns perfectly with the oil feed hole in the block. After installation, it is critical to check the inside diameter for proper clearance with the camshaft journals. If you are not experienced with this procedure, we recommend having it installed by a qualified diesel mechanic.

Q3: What is the typical lifespan of this cam bush, and what causes premature failure?
A: Under normal operating conditions and with proper lubrication, a cam bush can last for thousands of engine hours. Premature failure is often caused by contaminated oil (dirt or debris), low oil pressure, incorrect installation (misalignment or improper clearance), or excessive engine loading. Regular oil changes and using the correct viscosity oil are essential to maximizing the life of this component.
