Pro Tips, News & Events

CONEXPO-CON/AGG 2026 gave FridayParts the opportunity to connect directly with equipment owners and fleet teams facing real-world maintenance challenges. Instead of focusing on product promotion, the conversations centered on practical solutions—how to identify the correct part under pressure, confirm fitment across different machine configurations, and avoid costly ordering mistakes. Visitors explored parts manuals, discussed common issues like missing part numbers and inconsistent configurations, and looked for reliable yet cost-effective aftermarket options. The event highlighted a clear need for structured sourcing processes, from collecting accurate machine data to bundling maintenance parts and verifying compatibility before purchase. By turning quick booth interactions into actionable guidance, FridayParts continues to support off-road equipment professionals in reducing downtime and improving operational efficiency long after the show ends.

Machine vibrations and failing bearings often hide a simple problem. A Flexible Coupling is the low-cost insurance your powertrain needs to prevent costly damage from shaft misalignment. Discover the 3 main types and how they work!

Get a complete overview of the John Deere 855 specs, from its 24-hp Yanmar engine to its hydrostatic transmission and lift capacity. This guide helps you understand your tractor’s capabilities and find the right parts for any repair.

Can brake cleaner be used as starting fluid? It’s a common question on a cold job site, but the answer is a firm no. Learn why using this powerful degreaser can cause catastrophic engine damage and what to check instead.

Freightliner DTC Codes are essential diagnostic tools that help identify faults in heavy-duty trucks and equipment powered by Detroit Diesel engines. By understanding the SPN and FMI structure, technicians can quickly pinpoint issues in fuel, air, electrical, transmission, and safety systems without guesswork. This guide covers the most critical and commonly encountered codes, along with their symptoms, causes, and practical repair steps. From low fuel rail pressure and coolant temperature warnings to CAN communication errors and ABS system faults, each code provides insight into how the machine is performing and what needs immediate attention. By following a structured troubleshooting approach and prioritizing repairs based on severity, operators and fleet managers can reduce downtime, prevent costly failures, and maintain reliable equipment performance in demanding work environments.

A cracked pipe can stop your machine cold. But what if you could fix it in minutes? A simple pipe coupling is the answer. Discover the 3 main types and our 5-step install guide to get your equipment sealed and back to work, fast. Don’t let a small leak cause a big delay!

Komatsu code CA559 is commonly linked to low common rail pressure in the fuel system, a condition that can cause hard starting, power loss, black smoke, or a no-start situation in off-road machinery. This guide explains what code CA559 means, how it is typically reproduced, and how to troubleshoot it using a practical step-by-step process that begins with visible leaks and basic fuel supply checks before moving to pressure-related testing. It covers common causes such as external fuel leakage, low-pressure circuit faults, a leaking pressure limiter, excessive injector return flow, or a failing supply pump. The article also outlines the usual repair paths, including replacing clogged filters, servicing the water separator, repairing leaking fuel lines, and verifying that the system can build and hold proper pressure. By following a measured diagnostic workflow, technicians and equipment owners can avoid unnecessary parts replacement, reduce downtime, and restore reliable machine performance more efficiently.

Machine shaking? Power loss? The wrong shaft couplings might be the culprit. Our guide demystifies 10 common types, from flexible Jaw to high-torque Gear. Master the 3 key factors (torque, alignment, environment) and choose the perfect shaft coupling for a smoother, longer-lasting system.

In the Bulldozers vs Front-End Loaders debate, the job defines the machine. Dozers use tracks for powerful pushing and grading. Loaders use wheels for speed in lifting and hauling. We compare functions, mobility, and costs.

Correctly identifying a Carrier fuel pump is essential when diagnosing hard starts, fuel supply loss, or stalling in refrigeration units and related equipment. Because many pumps share similar shapes and mounting styles, relying on appearance alone often leads to ordering the wrong replacement. This guide explains how Carrier-style part numbers are typically structured, how to normalize and interpret the number printed on a pump label, and how to separate the prefix, core item code, and revision suffix. It also outlines a practical verification process that pairs the pump number with the refrigeration unit model, engine model, and electrical specifications such as voltage and connector type. By combining number decoding with fitment checks and visual confirmation, technicians can avoid common ordering mistakes, minimize downtime, and ensure the selected replacement pump meets the exact requirements of their Carrier equipment.

What is an axle and how does it give your machine power? This guide explains how an axle assembly supports weight and uses a differential and final drives to deliver torque to the wheels. We also cover axle types and failure signs.

Ignoring a worn coupling is like ignoring a flat tire—sooner or later, it will stop your whole machine. This small part plays a huge role. Do you know the difference between a rigid and flexible coupling? Choosing wrong can lead to vibration, bearing failure, and major damage. Learn to get it right.
