FAQ

Q: How do I confirm this bush fits my specific Perkins engine?
A: Check the stamped part number on your old bush. If it reads 3112E031 or 3112A005, this is the correct replacement. Also verify your engine model (e.g., 1104D-44) and the connecting rod part number if possible.

Q: What is the installation procedure for this connecting rod bush?
A: Installation requires a press tool to insert the bush into the connecting rod. After installation, the bush must be line-bored or honed to achieve the specific oil clearance required by the Perkins service manual (typically 0.05mm to 0.10mm). We recommend professional installation by a qualified diesel mechanic.

Q: Can this bush be used in high-horsepower or turbocharged applications?
A: Yes. This bush is made from a high-strength alloy suitable for both naturally aspirated and turbocharged engines in the 1100 series, such as the 1104T. However, for heavily modified or racing applications, we recommend consulting with our technical team for a heavy-duty upgrade option.
