Volvo D7D Engine Intake & Exhaust Valves VOE20405502 0428-3380 for Machinery

Product Details

Product Overview

This product consists of precision-engineered intake and exhaust valves specifically designed for the Volvo D7D diesel engine platform. The parts, carrying the OEM reference numbers VOE20405502 and 0428-3380, are critical components for maintaining proper cylinder sealing and efficient gas exchange within the combustion chamber.

Manufactured to original equipment specifications (OEM Size), these valves are commonly used in a wide range of heavy machinery applications, including construction equipment, industrial power units, agricultural tractors, gensets, and marine propulsion systems. As a direct replacement part, it is intended for use in Volvo D7D engines found in various models of excavators, loaders, and other heavy equipment.

Please verify your engine model (D7D) and existing part numbers before purchase to ensure correct fitment.

Key Features & Benefits

• OEM Specification Fitment: Manufactured to the exact dimensions and material specifications as the original Volvo part (VOE20405502), ensuring a direct, bolt-in replacement without modifications.
• High-Temperature Durability: Constructed from high-grade alloy steel designed to withstand the extreme thermal and mechanical stress within the D7D combustion chamber, reducing the risk of valve burning or deformation.
• Precise Valve Seat Interface: The valve face is precision-ground to ensure an optimal seal with the valve seat insert, maintaining compression pressure and preventing blow-by.
• Enhanced Engine Performance: Reliable valve operation ensures proper air intake and exhaust gas evacuation, contributing to maximum engine power output, fuel efficiency, and reduced emissions.
• Complete Set for Overhaul: This listing typically includes both intake and exhaust valves, providing a matched set for a comprehensive top-end engine rebuild or cylinder head service.

FAQ

Q1: How can I confirm these valves will fit my Volvo D7D engine?

A: The most reliable method is to remove your existing valve and compare it visually and dimensionally. Alternatively, locate the part number stamped on the old valve or your cylinder head service manual. If your engine is a Volvo D7D and the OEM number is VOE20405502, this is the correct part. If you are unsure, please contact our support team with your engine serial number (ESN) for verification.

Q2: Do I need to replace the valve guides and seals at the same time?

A: Yes, it is highly recommended. When replacing valves, always install new valve stem seals and inspect the valve guides for wear. Worn guides can cause oil consumption and poor valve seating, leading to premature failure of your new valves. This ensures a complete and reliable top-end rebuild.

Q3: What is the typical installation torque for the valve keepers/collets on the D7D?

A: Valve keepers (collets) do not have a torque specification as they are a locking mechanism. However, the rocker arm adjustment or valve clearance is critical. For the Volvo D7D, the standard cold valve clearance is typically 0.30mm for intake and 0.60mm for exhaust. Always refer to the official Volvo service manual for your specific engine variant to confirm the exact clearance settings and installation procedure.
