EGR is non-negotiable for NOx control on modern diesels—everyone knows that. But it’s also a source of headaches. Sticking valves, cooler cores plugging solid, position sensors that start lying to the ECM. That’s the trifecta. Let’s run through the basics first: what the system does, then where it bites you. The usual failure patterns are predictable—soot packing in the valve throat, coolant seepage into the gas side from a cracked cooler core, and feedback drift where the commanded position and actual position stop agreeing. When that happens, the driver feels it: flat power, a lumpy idle that shakes the cab, or a derate that kills your day. Here’s the thing—don’t fire the parts cannon. Fault codes give you a hint, not a diagnosis. I’ve watched guys throw three valves at a truck and still have the same code. Get into live data. Compare requested EGR position versus actual. Watch the temperature delta across the cooler. Monitor sensor voltage for jitter. That’s where the real story lives. Duty cycle is the big one nobody talks about. Highway miles with active regens? EGR tends to stay cleaner. Low-load, stop-and-go, extended idle? That’s what kills them early. Maintenance wise, pull the crossover pipe and look at the carbon crust—don’t guess. Check coolant condition weekly for signs of oil or combustion gas. Hit sensor connectors with contact cleaner, not compressed air—you’ll just push moisture in. Cummins, CAT, Deere, Perkins—they all respond to the same basic care. Skip it, and you’ll do the same job twice.
Understanding the starter solenoid wiring diagram is essential to troubleshooting and maintenance of your equipment. By knowing how the solenoid interacts with other key components, you can confidently diagnose your starting issue and do a replacement. Always keep this in mind: use the right tools and refer to your equipemt’s specific wiring diagram to ensure safe and reliable mowing.
Deciding on a new tractor battery? Our AGM vs flooded battery guide breaks it down. Learn how vibration resistance, maintenance, and charging needs differ. Choose an AGM for durability or a flooded battery for a budget-friendly option.
Learning how to start John Deere riding mower safely starts with the safety interlock system—seat switch, parking brake, PTO off, and transmission in neutral. This guide covers the 7-step starting procedure, why the mower may not start (dead battery, blown fuse, faulty switches), and troubleshooting no-start issues like a single click or engine cranking without firing. Different series (100, E, S, X, Z) have varying control layouts—check your manual. Before the first spring start, inspect old fuel, spark plug condition, battery charge, and fuel lines. Most no-start problems trace back to basic checks, not major failures.
Whether you operate an excavator, loader, bulldozer, or any other heavy equipment, a properly functioning fuel pressure regulator is essential to keeping your engine running smoothly. This guide covers everything you need to know about the fuel pressure regulator, from how it works and where to find it, to the warning signs of failure and how to test it.
Bought a used Hyster and was wondering what year your forklift is? This guide will be helpful. We’ll walk you through the Hyster serial number lookup and help you decode the year of your model.
Is your Toyota in limp mode with a P2118 code? This error points to a problem with the electronic throttle’s power supply. Our guide shows you how to diagnose the issue, from checking the ETCS fuse to cleaning the throttle body.
Finding the right WIX oil filter cross reference for your ATV, tractor, or skid steer isn’t always straightforward—model year, engine variant, and mounting position all change the answer. This guide explains how WIX part numbers work (51xxx for spin-on, 57xxx for extended-service), provides common lookup examples by equipment type, and shows how to confirm fit before installing. Never assume a filter fits based on machine model alone. Always check thread size, gasket diameter, bypass valve pressure, and anti-drainback valve specs. Whether you’re maintaining a compact tractor, excavator, or skid steer, a careful cross-reference saves time and prevents costly mistakes.
Facing a Cummins SPN 111 FMI 18 code? This fault means the engine’s coolant level is below the safe range, triggering a derate to prevent damage. Our guide walks you through the common causes, from leaks to faulty sensors.
The John Deere S100 riding lawn mower is a straightforward residential mower with a 17.5 HP single-cylinder engine, hydrostatic transmission, and 42-inch cutting deck. This guide covers the core specs—engine power, deck size, cutting height range, and fuel capacity—plus routine maintenance that keeps the mower running reliably. Most performance issues trace back to simple wear items: air filter, oil filter, spark plug, battery, blades, and deck belt. Regular checks before and after mowing prevent bigger problems down the road. Whether you’re troubleshooting a rough start or uneven cut, start with basic service before assuming major failure.
Error codes popping up on your engine? It’s quite serious because these codes affect the drivability of the vehicle and the performance of the engine. Ignoring these DTC codes might lead to further engine malfunction and damage. In this guide, we’ll talk about everything about the P0345 code, including the causes, symptoms, and easy fixes.
