The TAIHO Connecting Rod Bush (STD, P028H) is a precision engine component that supports the small end of the connecting rod and reduces friction between the piston pin and the rod during engine operation. This connecting rod bush provides a low-friction interface and helps reduce internal engine wear for smoother performance and reliable operation.

This standard size bush is suitable for engine rebuilds, overhauls, and maintenance applications where the original manufacturer specifies this bush size. TAIHO products are engineered to meet high performance and durability standards used in automotive engine bearing applications.

Key Features

• Standard size connecting rod bush manufactured by TAIHO

• Reduces friction and wear at the small end of the connecting rod

• Precision-made for consistent quality and fit

• Supports smoother engine motion and reduced internal stress

• Suitable for engine rebuilds, maintenance, and repairs

Technical Specifications

Function Overview

A connecting rod bush is pressed into the small end of the connecting rod to provide a bearing surface for the piston pin (also called a wrist pin). It minimizes metal-to-metal contact, distributes reciprocating loads, and supports the engine’s motion during combustion and piston travel.

Vehicle / Engine Fitment Guidance

This connecting rod bush corresponds to a standard piston pin / small end bush size (P028H) and is commonly referenced in parts catalogs for diesel engines such as the Toyota 11B and 13B engine series (3.0 L and 3.4 L) used in vehicles like Toyota Coaster and Toyota Dyna models from the mid-1980s.

Associated OEM reference numbers include:

• 90999-73099

• 9099973099

These numbers are often used in catalogs to cross-reference similar piston pin or connecting rod small end bushings. Always verify the OE/OEM part number shown on your original part or in the vehicle service manual before ordering to ensure correct fitment for your specific engine. If uncertain, consult a qualified mechanic or parts specialist.

OEM / Reference Part Numbers

• Manufacturer Part Code: P028H

• Catalog Reference: P028HSSTD

• Common Comparable OEM Codes: 90999-73099, 9099973099

These reference numbers help confirm compatibility with existing parts catalogs and engine specifications.
