Heavy Equipment Pre-Season Maintenance Checklist: Get Your Fleet Ready for a Busy Season

When construction season ramps up, the last thing any operator or fleet manager needs is unexpected downtime. A well-planned pre-season inspection doesn’t just keep your machines running, it saves money, prevents failures, and sets your team up for success all season long.
Whether you run excavators, wheel loaders, dozers or skid steers, this heavy-equipment maintenance list will help you spot issues early and maintain peak performance.

Below is a practical, easy-to-follow construction season prep checklist to guide your team.

1. Inspect All Pins, Bushings & Linkages

These parts carry the brunt of daily wear, especially in digging and lifting environments.

What to check:

  • Excessive play or slop in joints
  • Scoring, flattening, or uneven pin wear
  • Bushings that appear oval, cracked, or dry
  • Missing or damaged dust seals

Why it matters:
Worn joints quickly snowball into costly structural repairs. Early replacement of pins and bushings extends machine life and improves accuracy, safety, and breakout force.

2. Check Cylinders: Rods, Seals & Housings

Hydraulic cylinders drive nearly every function on an excavator and must be leak-free and perfectly aligned.

Look for:

  • Rod pitting, rust, dents, or chrome damage
  • Leaking or swollen seals
  • Rod drift or slow cycling
  • Cylinder mounting pin wear

Tip: If the rod coating is compromised, replace it early, seal kits alone won’t solve long-term issues.

3. Review Hydraulics: Hoses, Fittings & Fluid Condition

Your hydraulic system powers your machine’s most critical functions. Any contamination or damage can lead to catastrophic failure.

Your pre-season hydraulic inspection should include:

  • Checking hoses for cracks, abrasion, rubbing or bubbling
  • Tightening or replacing worn fittings
  • Inspecting fluid for cloudiness or metallic shimmer
  • Replacing filters according to your manufacturer’s schedule

Bonus Tip: Keep spare hoses and couplers in your service truck, spring schedules get tight fast.

4. Undercarriage Examination (Excavators, Dozers & Track Machines)

The undercarriage can be nearly half of an excavator’s lifetime operating cost, making pre-season prep essential.

Inspect the following:

  • Track tension
  • Rollers, idlers and sprocket condition
  • Wear patterns on pads and shoes
  • Track adjuster leaks
  • Final drive oil health and seal integrity

A detailed excavator inspection checklist keeps your most expensive system reliable throughout the season.

5. Engine Servicing & Fluids Check

Before temperatures rise and workloads increase, confirm your engine is ready.

Complete this list:

  • Change engine oil and filters
  • Inspect air filters and pre-cleaners
  • Test batteries and clean terminals
  • Inspect belts and cooling system
  • Replace fuel filters and drain any water separators

Engines work harder in warm weather, so fresh fluids and clean filtration make a noticeable difference.

6. Electrical & Safety Systems

Safe machines help crews work faster and avoid downtime.

Inspect:

  • Lights, indicators, and warning beacons
  • Backup alarms and cameras
  • Wiring harnesses for chafing or corrosion
  • Cab electronics and controllers

7. Ground Engaging Tools (GET): Teeth, Edges & Hardware

Worn GET reduces productivity and increases fuel consumption.

Check:

  • Tooth tips, adaptors, and retainers
  • Cutting edges on buckets and blades
  • Shank wear on rippers
  • Bolts and hardware tightness

If you swap attachments frequently, keep a fleet maintenance parts list handy for quick replacements.

8. Lubrication: Grease Points, Central Lube Systems & Condition

Proper lubrication is the easiest and most cost-effective way to prevent wear.

Pre-season lubrication tasks:

  • Grease all joints thoroughly
  • Inspect automatic lubrication systems
  • Replace clogged or damaged grease lines
  • Use the correct grease type for your climate

A well-lubricated machine is a smoother, more efficient machine.

9. Cab Comfort & Operator Controls

A comfortable operator is a productive operator, especially during long seasonal shifts.

Inspect:

  • HVAC system (heating/AC)
  • Seat condition and suspension
  • Controls responsiveness
  • Wiper blades and washer fluid
  • Cab glass for cracks or impairments

10. Stock Up on Common Wear Parts

Reduce downtime by keeping essential items on hand.

Recommended stock:

  • Pins & bushings
  • Seal kits
  • Filters (fuel, oil, air, hydraulic)
  • O-rings and hardware
  • Spare hoses
  • Bucket teeth and cutting edges

This ensures your team can complete repairs immediately instead of waiting for delivery.

Final Thoughts

Preparing your fleet before the season begins protects your equipment and your bottom line. With this heavy equipment maintenance list, you’ll reduce breakdowns, extend part life, and keep your machines running at peak output, all while keeping your crew safe and productive.

Happy prepping!
