Product Details
Product Overview
This D1146 Connecting Rod Screw is a precision-engineered fastening component specifically designed for integration with Doosan diesel engine systems. As a critical part of the engine’s bottom end assembly, this screw ensures the secure clamping of the connecting rod cap to the rod body, maintaining the precise bearing clearance required for high-performance operation. While the D1146 model designation is the primary reference, this component is commonly used in a wide range of heavy-duty machinery, including excavators, trucks, forklifts, bulldozers, buses, and loaders that utilize compatible Doosan engine platforms.
Manufactured to OEM size specifications, this connecting rod screw provides a direct replacement solution for maintenance and overhaul procedures. It is essential for technicians and fleet managers seeking reliable, cost-effective parts that do not compromise on structural integrity. Each screw is produced under strict quality controls to ensure it meets the demanding tolerances required in diesel engine environments.

FAQ
Q1: How do I confirm this D1146 screw fits my specific engine? A: Verify the engine model plate on your equipment. If it lists D1146, this screw is the correct specification. For absolute certainty, measure the thread pitch, length, and diameter of your original screw and compare it to the OEM size specification. We also recommend consulting your engine’s parts manual for the exact fastener part number.
Q2: What is the recommended tightening procedure for this connecting rod screw? A: Always follow the manufacturer’s service manual for torque specifications and tightening angles. Connecting rod screws are typically torque-to-yield (TTY) fasteners. If the original screw was a TTY type, it must be replaced with a new one (like this part) and not reused. Use a calibrated torque wrench and apply assembly lubricant to the threads if specified.
Q3: Can I use this screw for an engine rebuild or only for emergency repairs? A: This screw is perfectly suitable for both planned overhauls and emergency repairs. For a comprehensive rebuild, it is standard practice to replace all connecting rod fasteners. Using new, high-quality screws like this one ensures consistent clamping force and prevents bearing failure. It is a critical component for any full engine overhaul.
