Caterpillar Paver Parts

Aftermarket Caterpillar Paver Parts

Keep your Cat asphalt paver moving material evenly and producing a consistent mat with replacement wear parts and machine components from Construction Parts PNW. We help contractors source parts for Caterpillar track and wheel pavers used on highways, municipal streets, parking lots, airports, subdivisions, and commercial paving projects.

Our team can assist with current and earlier Caterpillar paver models, including AP-series machines and selected legacy configurations. Supply the complete model, serial number, arrangement or part number whenever possible so we can verify the correct fit before ordering.

Caterpillar Asphalt Paver Parts We Supply

An asphalt paver combines material delivery, propulsion, grade control, and screed systems. Wear in one area can affect material flow, machine tracking, mat consistency, and daily production. We source aftermarket and replacement parts across the systems that work hardest in paving applications.

Feeder and Conveyor System Parts

• Conveyor chains, bars, slats, and flight components
• Drive and idler sprockets
• Conveyor shafts, bearings, rollers, and hardware
• Floor plates, guards, and deflectors
• Feed sensors and related mounting components

The feeder system moves mix from the hopper toward the augers. Worn chains, sprockets, slats, or floor plates can create irregular delivery and accelerate wear across connected components.

Auger and Material Distribution Parts

• Left- and right-hand auger segments
• Auger shafts, extensions, and mounting tubes
• Bearings, supports, and drive components
• Conveyor-to-auger deflectors
• End gates and material-retention components

Auger parts distribute asphalt across the screed. Confirm the paver model, auger position, direction, diameter, and existing part number before ordering because similar-looking segments may not interchange.

Screed Plates and Wear Components

• Main and extension screed plates
• Nose bars and strike-off components
• End gates and wear shoes
• Tamper and vibration-system wear parts
• Heating-system components and mounting hardware

Screed wear can influence mat texture, density, and smoothness. Inspect plates for uneven thickness, distortion, cracking, and buildup, and evaluate related supports and adjustment points during replacement.

Hopper and Push-Roller Components

• Hopper-floor and wing wear plates
• Apron components and flashing
• Push rollers and mounting parts
• Hydraulic cylinders, pins, bushings, and hardware

Hopper components experience impact, heat, and abrasion during truck exchanges and material transfer. Replacing worn liners and related hardware helps protect structural components and maintain controlled material flow.

Undercarriage and Drive Parts

For Caterpillar track pavers, available components may include track pads or belts, bogies, rollers, idlers, tensioning parts, drive components, and mounting hardware. Wheel paver needs can include tires, drive components, steering parts, and related wear items. Exact availability depends on model and serial-number configuration.

Cat Paver Models and Screed Families

Caterpillar’s current asphalt-paver families include track models such as the AP455, AP555, AP655, and AP1055, plus wheel models such as the AP400, AP500, AP600, and AP1000. Screed configurations include SE-series vibratory, front-mount, and tamper-bar systems. Earlier AP “F” models and other legacy Cat or Barber-Greene-based machines may use different arrangements even when model names are similar.

Model number alone may not identify every component. Serial-number breaks, screed model, paving-width package, track or wheel configuration, and factory options can change the required part.

How to Identify the Correct Caterpillar Paver Part

Gather the following information before requesting pricing or fitment help:

• Complete Caterpillar paver model
• Machine serial number or product identification number
• Screed model and serial number when applicable
• Part number from the existing component
• Component location and left- or right-hand orientation
• Dimensions, mounting-hole pattern, and quantity required
• Clear photos of the installed part and surrounding assembly

For conveyor and auger parts, include shaft size, pitch, direction, and position. For screed components, include the screed model, section location, paving-width setup, and plate dimensions. Send these details through our Part Finder Request for identification assistance.

Common Signs of Paver-Part Wear

• Uneven or interrupted material flow
• Visible thinning, cracking, bending, or missing wear material
• Excessive conveyor-chain slack or inconsistent tension
• Rounded or hooked sprocket teeth
• Auger vibration, contact, or uneven distribution
• Mat streaking, drag marks, or inconsistent texture
• Uneven screed-plate thickness
• Track movement, alignment, or tension problems

Inspect connected parts as a system. Installing a new chain on severely worn sprockets—or new auger segments on damaged supports—can shorten the service life of the replacement components.

Plan Paver Maintenance Around Wear Systems

Daily cleaning and inspection help expose wear before it causes downtime. Follow the machine manufacturer’s service procedures, lockout requirements, and adjustment specifications. During scheduled maintenance, document wear measurements and part numbers so replacements can be sourced before the machine reaches a critical limit.

High-wear inventories commonly include conveyor hardware, auger segments, bearings, screed wear parts, end-gate components, and frequently replaced fasteners. The right stocking plan depends on the fleet, application, production schedule, and local parts availability.

Caterpillar Paver Parts FAQs

What information is needed to identify a Cat paver part?

Provide the machine model and serial number, the screed model when relevant, any existing part number, the component location, dimensions, and clear photos. Left- and right-hand orientation is especially important for auger and conveyor components.

Do parts differ between track and wheel pavers?

Yes. Propulsion, undercarriage, steering, and some supporting systems differ between track and wheel machines. Material-delivery and screed components can also vary by model and configuration.

Can you help with older Caterpillar paver models?

Availability varies, but part numbers, serial information, measurements, and photos can help our team research replacement options for current and earlier machines.

Should conveyor chains and sprockets be replaced together?

Inspect both as a matched wear system. A new chain running on heavily worn sprockets can wear prematurely. Replacement decisions should follow measured condition and the machine manufacturer’s service guidance.
