WD615 Valve Guide VG1540040008 612600040113 for Weichai Engines Construction Agriculture

Product Details

Product Overview

This high-quality valve guide, identified by part numbers VG1540040008 and 612600040113, is a critical component specifically designed for the cylinder head assembly of Weichai WD615 series diesel engines. As a direct replacement part manufactured to OEM size specifications, it ensures precise valve stem alignment and optimal heat dissipation.

Commonly applied in heavy-duty machinery including construction equipment, agricultural tractors, industrial generators, and marine propulsion systems, this valve guide is essential for maintaining engine compression and preventing premature valve and seat wear. The part is manufactured by and is available as a standard replacement unit, not a genuine Weichai part unless otherwise specified.

Key Features & Benefits

FAQ

Q1: Is this valve guide a direct replacement for my Weichai WD615 engine?
A: Yes, this valve guide (VG1540040008 / 612600040113) is manufactured to OEM size specifications specifically for the Weichai WD615 series. It is a direct replacement part. However, we always recommend comparing the dimensions (outer diameter, inner diameter, and length) with your old part to confirm compatibility, as there may be variations between different WD615 sub-models (e.g., WD615.61, WD615.67).

Q2: What is the proper installation procedure for this valve guide?
A: Installation requires specialized tools. The old guide must be pressed out from the combustion side of the cylinder head. The new guide should be pressed in from the top (camshaft side) to a specific height (protrusion) above the spring seat. It is critical to use a valve guide driver to avoid damaging the guide or the head. After installation, a reaming tool is often required to achieve the precise valve stem-to-guide clearance. We recommend having this work performed by a qualified diesel engine technician.

Q3: What other parts should I replace when changing the valve guides?
A: When replacing valve guides on a WD615 engine, it is standard practice to also replace the valve stem seals. It is highly recommended to inspect or replace the valves and valve seats if the engine has high hours. Replacing these components together ensures a complete valve job, restoring compression and preventing future oil consumption issues.
