Growshine International is your trusted global supplier for top-tier engineering machinery parts. We specialize in providing comprehensive undercarriage components for Caterpillar (CAT) excavators, ensuring your heavy equipment, including the popular models CAT 320, CAT 325, CAT 330, CAT 345, and CAT 336, maintain peak performance and reliability. Our commitment to quality makes us a leader in the export of construction equipment undercarriage parts.
The core of our offering includes robust track chain (Track Link Assembly), durable track plate (Track Shoe), essential chassis parts, four wheels (Track Roller, Carrier Roller, Idler, Sprocket), and various one-sided accessories (e.g., track guards, tension adjusters). We ensure that every component, from the smallest bolt to the complete link assembly, meets stringent quality standards for maximum service life. Trust Growshine for reliable excavator spares and heavy equipment track components.
Our inventory is stocked with high-demand Caterpillar undercarriage parts for various excavator classes. The track chain is built with precision-machined links and sealed pins and bushings for reduced wear. The track plate comes in various widths and cleat heights to suit different applications, from standard duty to extreme rock applications. Critical four wheels components include the Track Roller (Bottom Roller), Carrier Roller (Top Roller), Idler (Front Idler), and Sprocket (Drive Sprocket Segment or Rim). These are essential for the smooth operation and longevity of your CAT 320, CAT 325, CAT 330, CAT 345, and CAT 336 models. We also supply supporting chassis components and one-sided accessories to complete the repair or maintenance job efficiently.

Understanding your equipment is key to proper maintenance. Here are a few essential component definitions:
Track Roller (Bottom Roller): Positioned on the underside of the main frame, it guides and supports the weight of the excavator (e.g., Caterpillar 330D Track Roller).
Carrier Roller (Top Roller): Located on top of the main frame, it supports the weight of the track chain and prevents sagging (e.g., CAT 325C Carrier Roller).
Idler Wheel: Mounted at the front of the undercarriage, it guides the track chain and manages tension (e.g., CAT 345B Idler Wheel).
Sprocket: The toothed wheel driven by the travel motor, engaging with the track chain to propel the machine (e.g., Komatsu PC450-8 Sprocket Segment).
Hydraulic Pump: Located in the engine compartment, it converts mechanical power into hydraulic energy to power cylinders and motors (e.g., Hydraulic Pump related products are available).
Tie Rod End: Part of the steering linkage in the suspension system, connecting the rack to the steering knuckle (e.g., Ford F-150 Tie Rod End).
Fuel Injector: Located in the engine's cylinder head or intake manifold, it sprays fuel into the engine cylinders (e.g., Isuzu 6HK1 Fuel Injector).
Brake Pad: Fitted inside the brake caliper, it presses against the rotor to create friction for slowing the vehicle (e.g., Mercedes-Benz Actros MP4 Brake Pad).
PTO Shaft: Located at the rear of a tractor, it transfers mechanical power to implements (e.g., John Deere 7215R PTO Shaft).
Alternator: Mounted on the engine, it recharges the battery and powers the electrical system when the engine is running (e.g., Volvo FH16 Alternator).

The undercarriage is arguably the most critical and expensive part of an excavator like the CAT 336. It represents up to 50% of the machine's maintenance cost. The entire system is designed to provide traction, support the machine's weight, and absorb ground impact. Regular inspection of the track chain for pitch wear and the track plate for damage is vital. Proper track tension, managed by the idler and recoil spring, is crucial to prevent premature wear on the sprocket and track rollers. Using high-quality, matched components from suppliers like Growshine International ensures the longevity and efficiency of your CAT 320 undercarriage investment.
Problem: A Caterpillar 320D Excavator experiences slow or weak travel on one side. This is a common failure point for engineering machinery.
Cause: Often traced to insufficient hydraulic flow or pressure to the travel motor, which can be due to a faulty travel motor seal kit, a damaged final drive component, or a blocked hydraulic line. Less frequently, the main hydraulic pump or relief valve may be at fault.
Solution: First, check the gear oil in the final drive; milky oil indicates water ingress and damaged seals. Next, check the hydraulic pressure to the travel motor. If low, inspect the Travel Motor Seal Kit for leaks (which may require replacing the seals or the entire motor). If seals are good, a hydraulic system check for blocked filters or a malfunctioning pressure relief valve is necessary. Regular maintenance and prompt replacement of wear items like CAT 320 travel motor seal kit are key to preventing major failures.
