FAQ

Q1: Is this seal for the front or rear of the crankshaft?
A1: The part number 4006 is commonly used for both front and rear crankshaft positions on the Perkins 4000 series. However, you must verify the dimensions (ID, OD, Width) of your original seal. If you are unsure, please contact us with your engine serial number for confirmation.

Q2: What is the installation procedure for this oil seal?
A2: Installation is straightforward. Clean the housing bore and crankshaft surface thoroughly. Apply a thin layer of engine oil to the seal lip. Use a seal driver or a suitable socket to press the seal evenly into the bore until it is flush. Do not hammer directly on the seal body. Ensure the seal is not tilted during installation.

Q3: How can I prevent premature failure of this oil seal?
A3: Premature failure is often caused by a rough or damaged crankshaft surface, incorrect installation (tilting or over-pressing), or contamination. Always inspect the crankshaft for grooves or burrs before installation. Ensure the engine’s crankcase ventilation system is functioning properly to avoid excessive internal pressure that can push oil past the seal.
