6WF1 Main Bearing STD 1-11510093-5 Isuzu Engine Parts for Excavator & Truck

Product Details

Product Overview

This is a high-precision Main Bearing (Standard Size) designed specifically for the Isuzu 6WF1 diesel engine. Identified by the OEM part number 1-11510093-5, this component is a critical part of the engine’s rotating assembly, providing a durable, low-friction surface for the crankshaft. As a genuine replacement part, it is essential for maintaining proper oil clearance and supporting the high torque output of the 6WF1 powerplant.

Commonly used in heavy-duty applications such as excavators, loaders, bulldozers, forklifts, and trucks, this bearing ensures reliable engine performance during rebuilds or overhauls. The “STD” designation indicates it is a standard size bearing, intended for use with a crankshaft that has not been reground.

Key Features & Benefits

• Precision Engineering: Manufactured to strict OEM tolerances to ensure the correct oil clearance and optimal crankshaft support, reducing friction and wear.
• Durable Material Composition: Constructed from high-strength, wear-resistant materials to withstand the high loads and temperatures of a heavy-duty diesel engine.
• Confident Fitment: Directly replaces the original Isuzu part (1-11510093-5) for the 6WF1 engine without modification.
• Standard Size (STD): Ideal for engine rebuilds where the crankshaft is in good condition and does not require grinding to an undersize.
• Extended Engine Life: By providing a stable and precise bearing surface, this part helps prevent crankshaft damage and extends the overall service life of the engine.
• Rigorous Quality Control: Each bearing undergoes dimensional and material verification to ensure consistent performance and reliability.

FAQ

Q1: How do I know if I need a Standard (STD) or Undersize (0.25, 0.50) main bearing?

You must measure the crankshaft journal diameter. If the journal is within the manufacturer’s standard specifications (no wear or scoring), use a STD bearing. If the crankshaft has been reground to a smaller size (e.g., 0.25mm or 0.50mm undersize), you must use a corresponding undersize bearing. Always consult your engine service manual for exact specifications.

Q2: Is this bearing sold as a single shell or as a complete set?

This listing is for one (1) main bearing shell. A complete engine overhaul typically requires a set of 7 main bearings for the 6WF1 engine. Please check your requirements and purchase the appropriate quantity to complete your rebuild.

Q3: What is the correct installation procedure for this main bearing?

Installation requires precision. Clean the bearing saddle and cap thoroughly. Install the bearing shells dry, ensuring the locating tab fits into the groove. Apply a thin layer of clean engine oil to the bearing surface and the crankshaft journal. Torque the main bearing cap bolts to the manufacturer’s specified torque setting using a calibrated torque wrench. Always check the oil clearance using Plastigauge to ensure it is within specification.
