Transmission Parts For Construction Equipment

Heavy-duty construction equipment is built to take on harsh, rugged terrain, operating for hours to complete challenging jobs. No matter how well-built a machine is, something is bound to break sooner or later. Whether you discover a problem during routine maintenance or a breakdown happens on the job site, it’s crucial to replace the damaged parts as quickly as possible so your equipment can get back on the job.

As former equipment operators, we know that machine downtime is a profit killer. Plus, original manufacturer parts can be expensive, hard to find, and might not be built for the specific terrain or task you’re using the machine for. That’s where aftermarket parts come in. They offer similar or better quality to the manufacturer’s parts, but often at a lower cost. The variety of high-quality aftermarket components on the market allows you to replace broken parts and also optimize your machine for the task at hand. DMC Wear Parts is here to offer high-quality aftermarket parts to suit your needs.

Optimizing Your Equipment’s Transmission with Replacement Parts

It’s common to only think of replacing parts when something breaks, but aftermarket parts can also be used to improve your machine’s daily performance before a problem crops up. Replacing transmission shafts, upgrading your hydraulic system, replacing belts and hoses, and even swapping starters for newer, more efficient designs can optimize your machine, increase your uptime, and lengthen the time between necessary maintenance for your equipment.

Routine Maintenance Extends the Life of Your Machine

The worst time to need to replace a part is after it breaks, especially in the field. If a component fails while a machine is running, at best, it will cause unexpected downtime and lost profits. At worst, it could catastrophically damage the machine and cause far more costly repairs than the initial cost of the replacement part. Routinely checking and replacing belts, hoses, fluid levels, and other critical components of your undercarriage, engine, and transmission will significantly extend the equipment’s wear life.

Signs of Transmission Trouble in Construction Equipment

Preventative maintenance is the best kind of maintenance for heavy construction equipment, so it’s critical to be aware of and address any trouble that may be brewing in your machine’s transmission. If you see any fluids leaking, hear any unusual or loud sounds, or notice any foul smells coming from your machine, stop using it immediately and inspect it. Continuing to run a machine with a bad or leaking transmission can lead to even more costly damage down the road.

Leaking Fluids

There are tons of reasons your dozer, loader, or excavator may be leaking fluids, and none of them are good. Fluid leaks can be a sign of worn-out seals, damaged fluid lines, or a cracked transmission pan. If any of these components have gone bad, they should be replaced as soon as possible to prevent further damage to your machinery.

Strange Noises or Smells Coming from Your Machine

When you operate a machine for hours every day, you get a feel for its rhythms – what the machine sounds like when it’s working hard versus idling, or how long it takes for the engine to crank over when the weather is colder. If these usual noises change or you notice strange smells coming from your machine throughout the day, it’s time to inspect it. These changes are likely warnings of larger mechanical trouble on the horizon.

Aftermarket Parts vs. OEM Parts – Which is Better for Transmissions?

It’s a question almost as old as the machines themselves: Should I buy OEM (original equipment manufacturer) or aftermarket parts for my heavy equipment? When it comes to transmissions, aftermarket parts have a few distinct advantages.

  • Cost – Generally, OEM parts sold by manufacturers have a set price that doesn’t vary. Typically, aftermarket parts cost less than their OEM equivalents.
  • Quality – For an aftermarket parts manufacturer, designing and building new parts for heavy equipment machinery. During this process, the aftermarket manufacturer can identify and address any opportunity they find to improve the part’s function, materials, or design, often resulting in a similar or higher-quality part than the original.
  • Availability – DMC Wear Parts works with trusted suppliers and has over 50,000 parts in stock. Which means that when you order from us, our parts are more readily available than OEM options. We can typically get orders processed and shipped within 24 hours, reducing the downtime of your equipment and getting it up and running again sooner.
