When it comes to making sure your equipment stays in good working condition, sometimes this means finding replacement parts. Whether it’s due to regular wear or because of damage, there are several components that you should consider keeping readily available in case you need a quick repair. Equipment Trader is sharing some of the most common replacement parts and repairs you’ll have to make as an owner.

Why Replacement Parts Are Important

Having replacement parts on hand reduces downtime by keeping machinery in operational condition at all times. While owning supplies to regularly maintain machinery helps, having a back-up improves your maintenance schedule so you can keep up with units that require frequent repairs or replacements. It helps reduce operation costs from shipping replacements, too. You can reinforce safety standards by having spare components on hand when a machine malfunctions.

Common Replacement Parts

1. Filters

  • Engine air filter – This helps expand the engine’s lifespan, reduces emissions, and improves fuel efficiency.
  • Cabin air filter – This component protects the operator and cabin equipment.
  • Fuel filter – Filters keep contaminants from entering the fuel pump and clogging the system.
  • Hydraulic filter – Contaminated fluids can affect your hydraulic system’s performance, efficiency, and longevity. Being proactive in replacing this filter will block particles and keep your hydraulic system in operational condition.
  • Engine oil filter – This component stops contaminants in oil from reaching the engine, reduces leaks, and extends the engine’s life by preventing damage to oil pumps.

2. Fluids

  • Engine oil – Engine oil absorbs heat and lubricates equipment. It breaks down over time, so it must be replaced on a regular schedule to maintain the life and efficiency of your equipment’s engine.
  • Hydraulic fluids – These help with heat control and lubrication. Make sure you know your machine’s requirements for fluid viscosity and type.
  • Transmission fluid – Transmission fluid replacement helps to prevent wear, control heat, and improve performance.
  • Coolants – Replenish coolants as needed to control heat and inhibit corrosion. Conditions like extreme heat and cold require coolants to help prevent engine overheating, vaporizing, or freezing.
  • Diesel exhaust fluids (DEF) – These help reduce pollutants from reaching the diesel engine. Many machines with selective catalytic reduction systems require DEF.

3. Batteries

Heavy equipment often requires two batteries, one for startup and one for the machine’s electrical components. Most batteries will last around five years on average, but they can fail for several reasons such as improper charging, corrosion, and loose cables. Keeping extra batteries on hand can help avoid unexpected interruptions.

4. Engine Parts

  • Engine starters
  • Fuel injectors
  • Spark plugs
  • Seal kits and gaskets
  • Valves
  • Pistons
  • Bearings

5. Hydraulic Parts

  • Pumps
  • Valves
  • Cylinders
  • Hoses
  • Seals and O-rings

6.  Belts

Serpentine belts in heavy equipment deliver power to various components like the alternator, the power steering pump, and the air conditioning compressor. If this belt fails, the engine can overheat. Replace belts that have visible cracks, wear, or stripping.

7. Undercarriage Parts

  • Tracks
  • Track chains
  • Sprockets
  • Idlers
  • Rollers

8. Attachments

Failed attachments can delay work and interrupt production, and many of these parts have long lead times. Keep a list of common heavy equipment attachments you need for your inventory to reduce downtime. Used and rebuilt attachments can also help save time.

Other Factors to Consider

When choosing replacement parts for heavy equipment, it’s important to consider things like compatibility. Specific models may require parts that are made for those makes and models. Also consider the quality of the replacement parts. While spending more money might seem like an inconvenience at the time, quality replacement parts are more likely to have a longer life and be less susceptible to damage and wear. Ensure that the parts are durable, but also cost-effective.

Build Your Replacement Stock

Performing regular inventory checks and making sure components are being regularly restocked will help with equipment maintenance. With a solid inventory of replacement parts for any possible situation, work downtime and production interruptions will be reduced. Do a monthly inventory assessment and budget for a replacement order every two to three months.
