Wear Parts and Structural Parts

Wear and structural parts for heavy equipment are essential components that ensure the durability, stability, and performance of machinery. Structural parts are typically the key components of a machine’s frame and support systems, while wear parts are those that experience high levels of friction, pressure, or wear due to constant operation. Find all the spares parts available at Hickmah Auto Spares for all different kinds of heavy machinery for Caterpillar, Komatsu, JCB, XMG, Volvo and so many more. Below some of the structural and wear parts for heavy equipment that are available in different sizes, and part numbers.

Wear Parts

Wear parts are those that experience friction, impact, and wear during operation. These parts are designed to be replaced after a certain amount of use. Available in different sizes and part

Buckets (Excavator/Loader)
- The primary attachment for digging, scooping, and moving material.
- Examples: Excavator digging bucket, wheel loader bucket, grading bucket, rock bucket, and clamshell bucket.
Teeth (Bucket Teeth)
- Sharp, replaceable tips on buckets that help break into materials during digging.
- Examples: Excavator bucket teeth, loader bucket teeth, ripper teeth.
Wear Plates
- Heavy-duty plates that protect parts of the machine from excessive wear due to friction and contact with abrasive materials.
- Examples: Wear plates for excavator arms, loader buckets, and bulldozer blades.
Cutting Edges (for Blades and Buckets)
- The replaceable edge parts that are used in grading, leveling, and cutting through materials.
- Examples: Dozer blade cutting edge, grader blade cutting edge, and bucket cutting edge.
Track Shoes
- The individual components of the track that help distribute the weight of the machine and provide traction.
- Examples: Steel track shoes, rubber track pads, and bolt-on track shoes.
Roller Sleeves
- Protective sleeves for rollers that reduce wear from contact with tracks and undercarriage components.
- Examples: Track roller sleeves, carrier roller sleeves.
Pins and Bushings
- Cylindrical components that connect different parts of the machine, allowing movement while bearing heavy loads.
- Examples: Track pins, bucket pins, hinge pins, and bushings for arm or bucket connections.
Track Chains
- The links that connect the individual track shoes and allow the track to move around the undercarriage.
- Examples: Outer track chains, inner track chains.
Sprockets
- The toothed wheels that drive the tracks by engaging with the track links.
- Examples: Drive sprockets for excavators, dozers, and crawler cranes.
Idlers
- Wheels that guide the track and help maintain tension.
- Examples: Front and rear idlers.
Hydraulic Pumps & Motors
- Parts of the hydraulic system that are used to generate and control fluid pressure for the machine’s movement.
- Examples: Main hydraulic pump, steering hydraulic motor.
Filters (Hydraulic, Fuel, Air, Oil)
- Components that protect the engine and hydraulic system by trapping contaminants.
- Examples: Hydraulic filters, fuel filters, air filters, oil filters.
Seals & Gaskets
- Components that prevent leaks and ensure that fluids (oil, hydraulic fluid, etc.) remain sealed within parts.
- Examples: Hydraulic seals, engine gaskets, O-rings.
Ripper Shanks and Tips
- Used on dozers and excavators for breaking into hard material, typically for ripping through rock or frozen ground.
- Examples: Dozer ripper shank, excavator ripper tip.
Brake Shoes & Linings
- The components used in braking systems to provide friction and stop the equipment.
- Examples: Brake pads, brake linings, disc brake shoes.
Cylinders (Wear Components)
- The pistons within hydraulic cylinders that experience wear from constant movement.
- Examples: Hydraulic boom cylinder, lift cylinder.
Rubber Tracks (for Mini Excavators and Skid Steers)
- Tracks designed for lighter machines that operate on softer ground, providing traction while minimizing ground damage.
- Examples: Rubber tracks for compact track loaders, mini-excavators, and skid steer loaders.
Forklift Tines (Forks)
- Description: The lifting components used for material handling that experience significant wear from carrying heavy loads.
- Examples: Pallet forks, adjustable forks, lifting tines.
Wheels and Tires
- Wheels and tires are integral to the movement of wheeled machinery, with wear occurring over time due to friction with the ground.
- Examples: Pneumatic tires, solid rubber tires, steel wheels for forklifts.
Cutter Bars and Blades (for Grading/Plowing)
- Used in grading or plowing machines to smooth or clear surfaces.
- Examples: Road grader blades, plow cutter bars.

Structural Parts

These are the parts that provide the fundamental framework and support for heavy equipment, ensuring its strength, stability, and safety.

Chassis (Frame)
- The main structural framework that supports all other components of the machine.
- Examples: Crawler frames, wheel loader frames, truck chassis, and skid steer loader frames.
Cab (Operator’s Cabin)
- The enclosed space where the operator sits. It provides safety and comfort and houses controls for the machine.
- Examples: Steel reinforced cab, ROPS (Roll-Over Protection System) cab, FOPS (Falling Object Protection System) cab.
Boom and Arm (for Excavators and Cranes)
- The long, extendable parts of machines like excavators, cranes, and backhoes. They are responsible for lifting and moving material.
- Examples: Excavator boom, loader arms, and crane booms.
Counterweight
- A heavy weight added to the rear of the machine to balance the equipment and prevent tipping during operations.
- Examples: Counterweights on excavators and cranes.
Undercarriage Frame
- The structural support system that houses the undercarriage components, including tracks, rollers, and sprockets.
- Examples: Crawler undercarriage frame, wheeled undercarriage frame.
Track Frames
- A part of the undercarriage that supports and connects the track rollers and sprockets to the machine’s body.
- Examples: Front track frame, rear track frame.
Hydraulic Cylinders
- Large, heavy-duty cylinders that use hydraulic fluid to generate motion and are used for lifting, tilting, and extending equipment components like booms, arms, and buckets.
- Examples: Boom lift cylinders, arm extension cylinders, tilt cylinders.
Axles (for Wheeled Machines)
- Structural parts that connect the wheels or tires to the body of wheeled equipment. They transfer the load and ensure movement.
- Examples: Front axles, rear axles, tandem axles.
Lift Frame
- A structural part that supports the lifting mechanism on machines like forklifts and telehandlers.
- Examples: Forklift mast, telehandler lift arms.
Towing Pins & Hitch Points
- Used for towing heavy equipment or trailers. These parts are integral to transporting machinery.
- Examples: Tow hooks, towing pins, drawbars.

Both structural and wear parts are crucial for the efficient and safe operation of heavy equipment. Structural parts provide the foundational integrity of the machinery, ensuring it can withstand the stresses of operation. Wear parts, on the other hand, require regular maintenance and replacement due to the intense friction and impact they endure during use. Timely replacement of these parts is essential for preventing breakdowns and ensuring long-term performance.
