How Cat® Reman Gives You What
Counterfeit Parts Can’t

Caterpillar’s David Zalar has seen his share of counterfeit parts — and the catastrophic problems they can cause. Zalar says people who buy counterfeit parts go from saying, “I’m just not getting the power I want” to “Oh, I just ruined my engine.” Read on for Zalar’s tips on how to spot fakes and why he recommends choosing Cat® Reman parts instead.

Understanding counterfeit parts

 

Counterfeit parts are fakes or imitations, usually offered at a lower price than genuine products. They’re made to look like OEM parts, with logos, labels and part numbers copied from the originals. But they’re not produced by — or with the authorization of — the OEM, so they rarely meet the same quality, reliability and safety standards.

“They certainly don’t come with any guarantees if they’re not Cat parts,” says David Zalar, lifecycle manager for Caterpillar fuel systems.

Genuine Cat parts and Cat Reman components, on the other hand, are built to meet Caterpillar’s rigorous standards. Cat Reman parts, in particular, are designed and remanufactured by Caterpillar to perform like new, offering fast, drop-in ready solutions that cost a fraction of the price of new when you return a used part (also known as “core”)1.

 

Counterfeit parts vs. will-fit parts: What’s the difference?

 

Many will-fit parts are legitimate components, not fakes. They often come from well-known suppliers and are clearly labeled so you know they’re not OEM products.

That doesn’t make will-fit parts a “safe” option, though. According to Zalar, genuine OEM parts like fuel injectors are the result of time- and labor-intensive design and manufacturing processes. Will-fitters don’t have access to the same OEM specifications and must reverse-engineer their products.

“Without that type of background, many will-fitters will struggle to put together an injector and have the durability and reliability that comes with genuine new and Cat Reman injectors,” Zalar says.

 

4 tips for spotting counterfeit parts

 

Imitation parts can be tricky to identify, because many counterfeiters go to great lengths to make them appear authentic. Zalar recommends these four steps to spot them:

  1. Check packaging and labels. Genuine Cat parts and Cat Reman parts come in high-quality packages. Smudges, smears, inconsistencies in the logo and crooked labels are warning signs of fakes. Plus, authentic parts often include difficult-to-replicate holograms or security seals.
  2. Verify numbers. Cross-check serial numbers, part numbers or trim codes against official Cat records. “If you can’t read the serial number or it seems like it’s been sandblasted or cleaned, that’s also an indicator,” Zalar says. “We don’t let that stuff go out of our facilities.”
  3. Inspect workmanship. Some differences in quality are visible to the naked eye. Counterfeit parts often use lower-grade materials and have poor finishes, rough edges or mismatched components. They may also feel lighter or poorly constructed compared to authentic parts.
  4. Examine the warranty. Genuine Cat parts and Cat Reman parts come with a Caterpillar Limited Warranty2. An authorized Cat dealer can provide complete details about the applicable Caterpillar Limited Warranty.

Still unsure? Zalar suggests taking the part in question to an authorized Cat dealer location. The technicians there can help confirm its authenticity using specialized tools and databases.

Risks of using counterfeit parts in cat equipment

 

What’s the harm in using counterfeit parts, especially if they could save you money? Zalar cautions that the small amount you might save buying a counterfeit part could quickly be offset by the costs of dealing with any of these issues. After all, a fake part could outright fail — or lead to all sorts of problems that waste your time and money:

  • Equipment damage: Because counterfeit parts aren’t manufactured to Caterpillar specifications, they may fit incorrectly and malfunction, causing internal damage to your machine or engine.
  • Reduced performance: Fake parts aren’t designed to the same standards as genuine Cat parts. They could hurt your equipment’s efficiency, productivity or fuel consumption.
  • Increased downtime: Counterfeit parts may wear out faster than genuine Cat parts or cause unexpected breakdowns, leading to repair delays and disrupting your operation.
  • Safety hazards: Equipment malfunctions caused by counterfeit parts could put your operators, onsite personnel and machinery in danger.
  • Warranty issues: For Caterpillar warranty coverage, there must be an identifiable defect in Caterpillar material and/or workmanship. By installing a counterfeit part, you would be ineligible for a Caterpillar Limited Warranty that would otherwise cover a genuine Cat part.
  • Lack of compliance: The use of fake parts may cause your equipment to fail industry safety, emissions or environmental standards, which could result in legal issues or fines.





“[When considering repairs,] you have downtime. You have the cost of the parts. You have the cost of the mechanic. You also have the cost of loss of production. It’s a gamble you’re taking with that asset.”

—David Zalar, Lifecycle Manager for Caterpillar Fuel Systems



 

Cat Reman: less risk, more reward

 

So, what’s a good alternative to counterfeit or will-fit parts if upfront cost is a concern? Zalar recommends Cat Reman products as an affordable, accessible and like-new solution.

  • Accessible: You can choose from a line of over 8,000 products — including Cat Reman engines, components, parts and kits — available at more than 2,300 authorized Cat locations and on parts.cat.com.
  • Affordable: Across the entire Cat Reman product line, remanufactured Caterpillar parts cost 45-85% the price of new parts when you return your core1. They’re also backed by a same-as-new, 12-month Caterpillar Limited Warranty.2
  • Like new: Cat Reman parts are not rebuilt — they’re remanufactured to perform like new. They meet Caterpillar original performance specifications and incorporate critical engineering updates.

There are sustainability benefits, too. Returned core allows us to remanufacture end-of-life parts that pass inspections. That helps keep the Cat Reman supply chain stocked and helps reduce the amount of greenhouse gas process emissions, new materials and process energy used3.

Your role in cracking down on counterfeit parts

 

Making a conscious decision to choose genuine Cat parts and Cat Reman parts is the first step in stopping counterfeiters. But fake components are still out there. That’s why Caterpillar’s intellectual property team actively enforces patent and trademark rights. This includes enforcement against companies that sell counterfeit products, misuse Caterpillar’s trademark or sell products that infringe on Caterpillar’s patents.

In 2024, the team successfully enforced intellectual property rights against a wide range of companies selling various aftermarket parts, including fuel system products, filters and pistons.

“The harder we look, the more we find,” Zalar says.

So, here’s how you can help stay vigilant. Be wary of suspiciously low prices and shop online and in-store at authorized Cat dealers and, if you buy used parts, request maintenance records. If you suspect you've been sold a counterfeit part, report it to an authorized Cat dealer. And talk to your Cat dealer about alternatives like genuine Cat parts and Cat Reman parts. “Going through authorized Cat dealers is the best way to make sure you get the correct items,” Zalar says.
