If you operate loaders, backhoes, or forklifts day after day, you’ve probably noticed how sensitive these machines are to heat. When the transmission runs too hot, everything else starts to suffer — performance drops, gears slip, and expensive downtime follows. This article will help you understand exactly what a normal transmission temperature is, why overheating happens, and what you can do to prevent it.

When you get in an unfamiliar machine, the first question is often, which one is the brake? Unlike a car, off-road machinery has varied pedal setups where a mistake can be dangerous. This guide breaks it all down, helping you identify the brake, throttle, and dual-function inching pedals on wheel loaders, backhoes, and more. Learn the difference between wheeled and tracked machine controls and essential safety practices to operate any heavy equipment with confidence and safety.

A faulty transmission or warning light on your heavy equipment can mean serious downtime. Often, the problem is a failing speed sensor. Recognizing the bad speed sensor symptoms early is key to a fast, affordable fix. This guide covers the most common signs, including unstable or harsh shifting, inaccurate speed or hour meter readings, cruise control failure, and torque converter lock-up issues. Learn what causes a sensor to fail and how to get your equipment back to work without a costly transmission repair.

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.
