CAT 094-3890 RETAIN PLATE

CAT 094-3890 (0943890) is a high-strength steel mounting plate for Caterpillar construction machinery chassis/hydraulic systems. It is used for positioning and securing track tensioners, hydraulic cylinder supports, or valve assembly mounting brackets. Suitable for small and medium-sized excavators and loaders, it prevents parts from loosening or shifting, ensuring stable equipment operation (Cat® Parts).

Compatibility and Applications
Compatible Parts: Track tensioner connection ends, hydraulic cylinder supports, valve assembly mounting brackets, etc. Positions and secures components, distributes load, prevents loosening and displacement, and ensures installation accuracy and operational stability.

Application Scenarios: Medium to heavy-duty work conditions such as urban construction, road construction, and earthmoving. Compatible with small and medium-sized excavators, wheel loaders, chassis, and hydraulic systems, improving component installation stability and operational accuracy.

Core Functions: Positions and secures track tensioners, hydraulic cylinder supports, and other components, distributes load, prevents loosening and displacement, ensures stable operation of the chassis and hydraulic system, and extends component lifespan.

Installation and Maintenance Points
Installation: Clean the mounting surface and fixing plate surface. Check that the positioning holes and bolt holes match. Tighten high-strength bolts to the specified torque (approximately 280-320 N·m), ensuring a tight fit without gaps. After installation, check that the components are not loose or displaced.

Maintenance: Check the bolt tightness and the deformation/cracks of the mounting plate every 250 hours. Tighten any loose bolts immediately, and replace any deformed or cracked parts immediately to prevent component detachment or malfunction.

Replacement: Use original parts first. When replacing, verify the model and dimensions. After installation, test the relevant systems to ensure they operate normally, without abnormal noise or leakage, and guarantee stable equipment operation.
