The continuous track system is a distinctive feature that allows bulldozers, excavators, tanks and other heavy construction or military equipment to traverse most terrains with amazing mobility. While the concept of tracks may seem simple at first glance, there is an intricate interplay of various components that work in unison to deliver superior traction and flotation. In this article, we examine the key components that make up the continuous track system – the track roller, track chain, track shoe and track link.

Track Roller

As the name suggests, track rollers provide the rolling contact between the track and the underside of the vehicle. They are cylindrical in shape and mounted at intervals along both sides of the track frame. Typically made of hardened steel, track rollers must withstand heavy loads and impact loads while rolling.

Lubricated roller bearings within allow the rollers to rotate freely with minimal friction as the track moves. Their hardened exterior also resists wear from abrasion against the track components. Track rollers guide and support the track, distributing the vehicle weight evenly along its length for maximum traction and minimal ground pressure. Proper roller condition and alignment is critical for smooth track operation.

Track Chain

The track chain is the main load-bearing backbone member of the track system. It is composed of consecutive track links connected through either bushings or pin joints. Track chains for heavy machinery come in various designs like single grouser, double grouser or tri-link configurations for different applications.

Each track link has an aperture that passes around a sprocket tooth at the front or rear of the vehicle for tractive drive. This propels the endless loop of the track around the track rollers through constant motion of the drive sprocket. Track chains are made of hardened alloy steel for strength and durability under punishing field conditions over long service life.

Track Shoe/Grouser

Track shoes are the removable ground-engaging components that provide traction. They are individually bolted or pinned to each track link. Most modern track shoes have extra projections called grousers or lugs that effectively engage with soil, rocks or other rough terrain for maximum grip.

Track shoes take the brunt of wear and are usually the first parts to require replacement. Hardened alloy steel and tungsten carbide inserts in the sole provide abrasion resistance. Shoe designs are optimized for different soil/surface types with varied lug configurations, width and material composition. Track shoes spread the vehicle weight for low ground pressure while their self-cleaning and self-sharpening properties maintain traction.

Track Link

As the primary load-bearing member of the track assembly, each track link is a rigid, closed-shape unit that connects multiple components together. The most common type is a single-piece, end-connected link with side plates joined by a top center guide.

Track links feature a large center aperture to engage sprocket teeth for power transmission from the drive sprocket. Their side walls support and guide the track rollers. Bottom recesses hold track shoes securely in position through attachment hardware. Grease fittings allow lubrication of link surfaces and inner cavities that keep links workable.

Different link designs exist optimized for weight carrying capacities, ground pressures and terrain conditions. Properly manufactured track links from hardened alloys can withstand years of cyclic stresses without failing structurally. The smooth articulation and flexible movement of interconnected track links enables the continuous track system to conform to uneven ground conditions.

In summary, continuous track vehicles leverage the co-ordinated function of each track system part to achieve unmatched flotation and traction capabilities across diverse work environments. Tuning the design, material selection and maintenance of track rollers, chains, shoes and links is vital to maximize heavy equipment performance, productivity and service life over tough operating cycles.

The undercarriage on track-type dozers and tractors is a complex system of interconnected parts that bear the brunt of demanding work. The undercarriage includes track assemblies, rollers, idlers, sprockets, and carrier rollers that enable the dozer to move and turn while supporting immense weight. These components experience extreme wear and must be maintained properly to maximize uptime. In this blog, we’ll examine the vital role dozer undercarriage plays and best practices for keeping it in peak condition.

Main Undercarriage Components And Function

The key elements of a dozer’s undercarriage include:

• Tracks: Made up of linked or grouser steel plates, tracks distribute vehicle weight and provide traction. The tracks wrap around drive sprockets and rollers.
• Rollers: Located between front idler and rear drive sprocket, rollers help support track weight and reduce friction.
• Idlers: Idler wheels at the front maintain proper track tension and alignment.
• Sprockets: Gear-like drive sprockets at the rear engage and move the tracks.
• Carrier Rollers: On some models, smaller carrier rollers provide additional track support between rollers.

Proper undercarriage care is essential for dozers to maintain productivity. But with vigilant maintenance and parts rotation, decades of reliable service life can be achieved.

The Caterpillar 320 and 325 excavators are workhorses in the compact size class, known for their durability and versatility on job sites. Whether you use your Cat 320 or 325 for general excavation, trenching, landscape projects or utility work, parts wear is inevitable and affects performance over time. Proper maintenance and installing genuine Cat excavator parts when needed will help prolong the life of your C series excavator.

The engine is the lifeblood of any excavator. The Cat320 and C325 models come equipped with a Cat C3.4 diesel engine. Over hundreds of operating hours, engine parts like the air filters, fuel filters and oil filters will need regular changing. Engine oil should be changed every 250 hours to flush out contamination and keep the parts lubricated. Other wear parts like glow plugs, fuel injectors and injector O-rings will deteriorate and ultimately require replacement. Keeping the engine well-maintained reduces down time, prolongs component life and optimizes fuel efficiency.

A robust undercarriage system as stability and mobility

A robust undercarriage system is crucial for stability and mobility when working in challenging conditions. Look for excessive wear of the tracks and rollers which could lead to derailment or uneven movement. The tracks on Cat 320 and 325 excavators are designed for maximum durability, but still have service limits of around 1,200 to 1,800 machine hours depending on work conditions. Inspect track components such as tensioners, fasteners, idlers and bushings for proper adjustment and signs of damage. If an undercarriage part fails prematurely, consult a Cat dealer to determine if a defective part needs to be replaced under warranty.

The hydraulic system functions – boom, stick, bucket and swing

The hydraulic system operates all of the working functions of the excavator including the boom, stick, bucket and swing. Over time, hydraulic oil breaks down and accumulates contaminants which reduce efficiency. Change the hydraulic oil filter after the first 50 hours, then every 500 hours or annually. Monitor hydraulic lines and hoses for leaks, abrasion, bulging or cracking and replace as needed. The hydraulic cylinder rods and seals can also fail prematurely, resulting in less than optimal digging power. Genuine Cat hydraulic parts are manufactured to the strictest specifications to maximize pressure handling and service life.

Additionally, common wear parts for Cat 320/325 excavators include the bucket and teeth/tips, loading and attachment cylinders, control levers and cab components. The bucket experiences the most punishment and typically needs to be replaced every 1,500 to 3,000 hours depending on material types being handled. Worn bucket edges can be repaired by welding, but complete replacement may be necessary if the side plates are damaged. The bucket teeth take the initial impact of rocks and debris, so they require frequent changing to maintain digging productivity.
