Caterpillar Grader

Gasket-8D-4064

PRODUCT DESCRIPTION:

This 8D-4064 gasket is a professional OEM-matched sealing and cushioning accessory exclusively engineered for Caterpillar Motor Grader 14/16, widely applied to the sealing of regular and irregular metal joint surfaces of the machine’s hydraulic system, lubrication system, transmission housing and pump valve assembly. As a core basic sealing part for daily maintenance and overhaul, it ensures the airtight connection of key mechanical components, prevents fluid medium leakage and external impurity intrusion, and provides reliable sealing and structural protection for the stable operation of the motor grader under heavy-load, high-vibration and dusty construction conditions.

PRODUCT DETAILS

Key Advantages

1. OEM Standard Perfect Compatibility : Strictly manufactured in accordance with Caterpillar’s original technical drawings and precision requirements, the overall size, thickness and mounting hole position of the gasket are 100% matched with the joint surfaces of Caterpillar 14/16 motor grader key components. No secondary cutting, drilling or modification is required, ensuring a seamless fit with original machine parts and fasteners.

2. High-performance Durable Composite Material : Adopts industrial-grade oil-resistant composite sealing material with excellent compression resistance, high temperature resistance and corrosion resistance. The material can withstand long-term erosion of hydraulic oil and lubricating oil, and adapt to the harsh construction environment of heavy load, dust and alternating temperature without deformation, aging or hardening.

3. Ultra-precise Forming & Burr-free Surface : Processed by high-precision CNC stamping and cutting equipment, the gasket has a smooth and burr-free sealing surface with extremely small dimensional tolerance. It ensures close contact with the metal mating surface, effectively avoiding seal failure caused by dimensional deviation and surface defects.

4. Strong Structural Stability & Long Service Life : The material has good shape retention and anti-aging performance, no warping, cracking or peeling after long-term use under high temperature and high pressure; the optimized material formula enhances the gasket’s resistance to extrusion and wear, greatly prolonging its service life and reducing the frequency of replacement and maintenance.

5. Simple Installation & Efficient Maintenance : Conforms to the original machine’s assembly design with a simple and integrated structure, which is in line with the daily maintenance operation habits of construction machinery maintenance personnel. The replacement can be completed quickly with conventional tools without professional technical support, significantly improving the on-site maintenance efficiency of the grader.
