Used Caterpillar Spindles: Extensive Stock of Spare Parts for Construction Machinery

Detailed Overview of Our Caterpillar Spindle Stock

Our central warehouse offers a wide selection of used axle spindles for Caterpillar machinery. These essential transmission components are carefully tested in our workshops to guarantee their proper function. Our inventory includes spindles compatible with major models of wheeled excavators, loaders, and articulated dump trucks from the brand. Each spindle undergoes rigorous inspection of bearing seats, sealing surfaces, and mounting points before being stocked. Dimensional tolerances are checked with micrometer precision to ensure optimal assembly. Our inspection process also includes a thorough check of splines and threads. This technical rigor ensures the highest quality parts, reducing the risk of failure in the field.

Compatible Machine Models

Our range of used spindles covers a wide array of Caterpillar equipment, including the 735B articulated dump trucks, M315 wheeled excavators, and D8H bulldozers. Available references also fit models 770, D6TXW, D6D, 977, and 769D. Our technical expertise allows rapid identification of compatibility between different equipment series. Successive technical updates of models are documented in our database, facilitating the search for the right part references. This deep understanding of Caterpillar specifications guarantees a perfect match with your machine, including older series requiring specific parts.

Technical Features of the Spindles

Caterpillar axle spindles stand out for their robust design adapted to the demands of construction sites. These transmission parts withstand significant dynamic loads during equipment movement, reaching several tons depending on the model. Bearing seats are machined with precision to guarantee optimal alignment, maintaining tolerances below 0.02 mm. The multilayer sealing system effectively protects against dust and water ingress, thanks to labyrinth seals and high-performance O-rings. Strategically placed lubrication points facilitate preventive maintenance by allowing grease injection directly into critical areas. The alloy used offers high resistance to wear and impact, with optimized surface hardness for harsh operating conditions.

Associated Parts and Complete Kits

To optimize maintenance work, we provide Caterpillar suspensions and components related to spindles. These kits notably include high load capacity tapered bearings, reinforced sealing rings, and treated steel circlips necessary for assembly. Availability of related parts such as 6 or 8-stud hubs, splined drive shafts, and high-strength ball joints enables complete system refurbishment. This comprehensive approach reduces downtime by avoiding multiple orders. Our extensive stock of over 17,000 references ensures immediate availability of frequently used components, especially for wheeled excavators and articulated dump trucks.

On-Site Installation and Assembly

Replacing an axle spindle requires precise methodology to ensure optimal operation. The procedure begins with thorough cleaning of contact surfaces using a technical solvent and verification of assembly dimensions with a dial gauge. Positioning of double-lip seals and angular contact bearings requires specific tools such as calibrated mounting sockets to prevent damage. Axial play adjustment, maintained between 0.05 and 0.15 mm depending on the model, and torque tightening of fasteners follow a strict protocol with values defined by the manufacturer. Final checks of movement, pressure sealing, and operating temperatures validate the quality of the intervention.

Codimatra's Expertise in Transmission

With over 40 years of experience in used Caterpillar transmission parts, we offer personalized technical support. Our specialists master the specificities of each axle spindle model and their technical evolutions, from older series like the D6D to recent versions equipping M315 excavators. This expertise enables precise identification of compatible references for your machine thanks to our comprehensive technical database. In-depth knowledge of mechanical constraints, including radial loads reaching up to 12 tons on some models, guides our recommendations to optimize part lifespan. Our technical service remains available to answer specific questions during assembly and provide post-installation follow-up.

Our Range of Refurbished Spindles

The axle spindles offered undergo rigorous inspection in our workshops. The control process includes precise micrometric dimensional measurements and thorough evaluation of the condition of functional surfaces, such as bearing seats and sealing areas. Parts showing acceptable wear, below 0.05 mm on critical diameters, are refurbished following strict criteria. This quality approach guarantees technical characteristics similar to original references, with concentricity controlled to 0.02 mm. Systematic replacement of sealing components, including high-performance O-rings and labyrinth seals, ensures optimal reliability in use. Each spindle also undergoes a rotation test to verify the absence of sticking points and the quality of sliding surfaces.

Availability and Shipping Times

Our logistics organization ensures quick shipment of axle spindles in stock. Suitable packaging, using reinforced wooden crates and specific shock protections, safeguards parts during transport while facilitating identification through detailed labeling. Orders confirmed before 3 p.m. generally benefit from same-day dispatch, with a service level exceeding 95%. Our network of professional carriers covers the entire territory with optimized delivery times: 24 hours for neighboring regions and a maximum of 48 hours for the most remote areas. Real-time parcel tracking through our dedicated interface allows anticipation of delivery and intervention planning. Our logistics team remains available to respond to your specific delivery needs.

How to Choose Your Used Spindle?

Selecting a used axle spindle requires consideration of several essential technical criteria. Accurate identification of the equipment model and its original configuration is fundamental, including the serial number and manufacturing year that determine technical specificities. Bearing seat dimensions, with strict tolerances of 70.01 mm, number of mounting points, and type of sealing must exactly match original specifications. Our technical team assists you in this process by verifying the compatibility of available references using our complete technical database. High-resolution detailed photos and technical characteristics provided, including dimensional measurements and the condition of critical surfaces, facilitate validation of your choice. A preliminary diagnosis of your machine also helps identify potentially associated components to replace for optimizing part lifespan.
