The TAIHO Connecting Rod Bush (STD, P035H) is a precision engine component designed to support the small end of the connecting rod and reduce friction between the piston pin and the rod during engine operation. This standard size bush provides a durable, low-friction surface that helps ensure smoother movement and reduced internal wear in the engine’s reciprocating assembly.

This part is ideal for engine rebuilds, overhauls, and maintenance work where the original manufacturer specifies this bush size. TAIHO products are made with precision materials and engineering to deliver reliable performance.

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

Detailed Technical Specifications

Standard Application Detail:
This bush is typically used as a piston pin / small-end connecting rod bushing in engines where the pin diameter is approximately 29 mm and standard factory bushings are specified. These conditions apply in many Toyota diesel engines such as B and 2B series.

Function Overview

A connecting rod bush is installed into the small end of the connecting rod where it provides a bearing surface for the piston pin (also called a wrist pin). It minimizes metal-to-metal contact, distributes reciprocating loads, and supports smooth transfer of motion between piston and crankshaft during engine operation.

Vehicle / Engine Fitment Guidance

This connecting rod bush P035H corresponds to a standard small-end bushing size commonly used in diesel engines where such pin bushings are specified (for example, Toyota B and 2B series engines with ~29 mm piston pins). Fitment depends on your specific engine code, year, and service manual specifications.

To ensure correct fitment, always verify the OEM part number and engine specifications before ordering. If you are unsure, consult a qualified mechanic or parts specialist.
