A faulty ignition switch can bring your heavy equipment to a halt, causing frustrating downtime. This guide helps you identify the warning signs, from an engine that won’t start or stalls unexpectedly, to flickering dash lights. We explore the common causes like wear and tear, corrosion from harsh environments, and loose wiring. You’ll learn practical DIY troubleshooting steps, like the “wiggle test” and checking relays, to diagnose your ignition switch. Know when to tackle the repair yourself and when it’s time to call a pro.

This guide to caterpillar fault codes troubleshooting teaches you to turn a diagnosis into a solution. Before replacing parts, learn our 3-step logic to find the root cause. We cover common codes like CID 0100 (oil pressure) and CID 0651 (injector) to help you fix your machine the right way.

When dealing with off-road machinery, stripped bolts can significantly slow down the maintenance process, delay the operation schedule, and even lead to costly downtime. No matter whether you are repairing the hydraulic cylinder, disassembling the wheel hub, or working on the excavator undercarriage, it is of great importance to master the proper way of safely removing the damaged bolt. In this guide, we shall introduce several time-tested methods and practical advice by which you may efficiently remove the stripped bolts and prevent such matters from occurring again.

Dark oil stains under your heavy equipment? It might be a rear differential leak, a common but serious issue. This guide helps you identify the symptoms, from oily residue and drips on the ground to whining or grinding noises that signal major trouble. We explore the primary causes for off-road machinery, such as worn seals, clogged breather vents, and physical damage. Learn how to pinpoint the source of the leak and get step-by-step instructions for a proper repair. Fix it right to prevent costly damage and keep your machine running strong.

When a P0037 code lights up your dashboard on a heavy-duty on-road truck, it signals that your aftertreatment system isn’t working as it should. But this issue is fixable when you know where to look. In this article, we’ll explain what Code P0037 means, why it happens, and how to repair it effectively. We’ll also touch on rare cases where similar issues might appear in non-road equipment powered by similar Tier 4 Final engines. Suppose you own or operate heavy trucks or specialized off-road machinery with emission-controlled diesel engines. In that case, this guide is designed to help you avoid downtime, reduce fuel consumption, and prevent unnecessary part replacements.

Failures in heavy off‑road equipment rarely happen overnight. In most cases, they are the result of gradual neglect, unnoticed wear, or skipped inspections. A wheel loader is a powerful and resilient machine, but it depends on well‑maintained systems — hydraulic, electrical, cooling, and drivetrain — to deliver peak performance. When one of these systems weakens, signs begin to appear: noises, fluid leaks, power loss, or overheating. This article explains the most common 7 warning signs that your loader is failing, why they happen, and how we can prevent them.

A failing EGR cooler can sideline your equipment and lead to costly engine repairs. Learn the common warning signs—from engine overheating to specific fault codes—before it’s too late. This complete guide from FridayParts covers symptoms, diagnosis, replacement costs, and preventive maintenance to protect your engine and keep your operation running efficiently.

Many owners think a clogged hydraulic oil filter just stops working. The reality is far more damaging. When impurities block the filter, a bypass valve opens, unleashing contaminated oil directly into your heavy equipment’s core. This unfiltered fluid accelerates wear on expensive pumps and valves, causing sluggish performance, power loss, and costly failures. Learn how this destructive chain reaction happens and what you can do to prevent it, protecting your investment and maximizing uptime.

Checking and maintaining proper track tension on a Bobcat excavator is one of the most effective ways to extend the life of your undercarriage parts, prevent costly downtime, and maintain smooth operation on any job site. The right tension keeps the track in sync with sprockets and rollers, preventing wear and energy loss. In this guide, we’ll show you step by step how to check and adjust your Bobcat excavator parts for ideal track performance.

A squealing 6.7 Cummins is a warning sign. It could be a failing idler pulley. Our complete guide covers symptoms, replacement cost, and step-by-step DIY instructions to prevent costly downtime and keep your heavy equipment running reliably.

Don’t ignore a glowing Steering Wheel Light! It signals a critical safety issue. This guide helps you diagnose the cause, covering hydraulic, electronic, and mechanical systems. Learn simple checks, when to use a scan tool, and the importance of a SAS reset to fix the problem correctly.

Brake fluid sits in your equipment’s brake system, out of sight and often out of mind. Many operators and owners completely ignore it, focusing on more obvious maintenance like oil changes. But neglecting brake fluid changes creates serious safety risks and expensive repair bills. Let’s look at exactly what happens when you skip this critical maintenance.
