As the weather turns cold and the days shorten, your construction equipment faces new seasonal challenges that can lead to unexpected (and costly) failures. In this article, we’ll provide essential seasonal equipment service tips, from monitoring fluids to checking critical wear points, to help you ward off those terrifying, unscheduled excavator maintenance issues and keep your fleet operational all through the fall and winter.

The True Horror: Unscheduled Downtime

For a contractor or project manager, few things are scarier than a critical machine going down mid-project. The shift from mild fall days to freezing winter weather stresses every part of your equipment, from the engine to the tracks. Neglecting preventive maintenance now is a surefire way to invite premature component failure and productivity drains.

At Coastal Machines, our technicians always emphasize a proactive approach. Based on our experience in the field, a small investment of time in checking fluids and wear parts today can save thousands of dollars and dozens of man-hours in repair and recovery later.

The Fall Maintenance Checklist: Scaring Away Breakdowns

The cooler weather demands a focused inspection of the systems most sensitive to temperature and moisture changes. Here are the critical areas to focus on right now:

1. The Lifeblood: Hydraulic Oil Checks

Your hydraulic system is the powerhouse of your equipment, and it’s highly sensitive to fluid quality and temperature.

• Check Viscosity: As temperatures drop, hydraulic fluid thickens. Ensure you are using the correct grade of fluid as per OEM specs for cold weather operations. Using an oil that is too thick can strain pumps and cause sluggish performance.
• Contamination Test: Water contamination is common as humidity rises and temperatures fluctuate, leading to condensation. Contaminated oil can rapidly degrade internal components. Our service team recommends a fluid analysis if the machine has seen heavy use or extended storage.
• Inspect Hoses and Seals: The change in temperature can cause hydraulic hoses and seals to become brittle or shrink slightly, potentially leading to leaks. Look for bulges, cracks, or signs of weeping around connection points.

2. The Foundation: Undercarriage Inspection

The undercarriage of compact track loaders (CTLs) and excavators takes a beating, and wet, muddy fall conditions exacerbate wear.

• Clear Debris: Mud, leaves, and rocks trapped in the undercarriage can freeze in place, causing increased tension on tracks and rollers. Regularly clean out the undercarriage to prevent premature wear on sprockets and idlers.
• Track Tension: Improper track tension is the leading cause of premature undercarriage wear. According to manufacturer guidelines, tension must be set correctly based on the operating conditions. Too tight, and you risk snapping components; too loose, and you risk de-tracking.
• Roller and Idler Checks: Inspect rollers and idlers for signs of oil leaks (a seal failure) or abnormal flat spots. Catching a seized roller early can save you from replacing an entire track.

3. Powering Through: Engine & Fuel System Care

Cold starts are hard on diesel engines. Proper servicing now ensures reliability when the mercury drops.

• Antifreeze/Coolant: Check the coolant level and its freeze protection rating. Ensure it’s protected against the lowest expected temperatures in your region.
• Batteries and Terminals: Cold weather severely reduces battery cranking power. Clean corrosion from terminals, check connections, and load-test any battery showing signs of weakness.
• Fuel Filters: Diesel fuel gelling is a risk in freezing temperatures. Ensure your fuel filters are clean and consider adding anti-gelling additives or switching to a winter-grade blend as recommended by your supplier.
