Some lessons cost you time. Some cost you money. And some—like the one I’m about to tell you—cost you both, plus a decent chunk of professional pride.

This happened in September 2022. I was handling spare parts orders for a small crushing operation, and we’d just taken delivery of a second-hand Kleemann MR 110 Z EVO 2. The machine was a beast—compact, powerful, and packed with that fancy EVO technology. But it was also new to our fleet, which meant we didn’t have the usual bin of spare parts sitting around.

The Setup: A Tight Budget and a ‘Smart’ Idea

Our budget was tight—it’s always tight when you’ve just dropped six figures on a used crusher. The project manager looked at me and said, “We need a stock of consumables: blow bars, a few wear plates, filters. Can you make it work without the Kleemann tax?”

I knew what he meant. OEM parts are expensive. A genuine Kleemann blow bar for the MR 110 Z EVO 2 can run $400–$600 each, depending on the manganese content. And when your machine chews through a set every 150 hours (more if you’re feeding it abrasive material), that adds up fast.

So I did what any budget-conscious procurement guy would do. I went hunting for aftermarket alternatives.

I found a supplier online. They claimed their parts were “direct replacement” for the Kleemann MR 110 Z. They had a website that looked professional. (Should mention: I didn’t check the “about us” page carefully. It listed a P.O. box.) They quoted me $3,200 for a full set of blow bars, a few apron feeder liners, and some filters. The OEM quote was $5,100. I saved $1,900. Or so I thought.

The Turning Point: When Things Didn’t Fit

The parts arrived in October—three weeks late, which should’ve been a red flag. I pulled one of the blow bars out of the crate. It looked… okay. The dimensions seemed close, and the mounting holes lined up. But the fit was off. It sat about 3mm too high in the rotor pocket. Not a huge gap, but enough that it didn’t seat flush.

I called the supplier. “Have you tested these on an EVO machine?” I asked. “Oh yeah,” they said. “They’re the same as the older MR 110.”

That was the problem in one sentence.

The EVO series—the MR 110 Z EVO 2, the MR 130 Zi EVO 2—have different rotor geometry than the pre-EVO models. The Kleemann engineers tweaked the pocket depth and the blow bar profile to optimize the crushing chamber. It’s not a massive change, but it’s enough that a generic “fits all MR 110” blow bar won’t work right.

I installed one anyway (ugh, desperation). The crusher ran for about an hour before I noticed unusual vibration. We stopped the feed, opened the chamber, and found the blow bar had shifted. It had been hammering the rotor pocket, creating micro-fractures in the rotor itself. $3,200 worth of parts, plus potential rotor damage that could cost $5,000–$8,000 to repair.

Never expected a 3mm fitment issue to cause that kind of danger. Turns out, the margin between “direct replacement” and “damaging your machine” is thinner than most aftermarket suppliers admit.

The Aftermath: Back to OEM, With a Side of Humble Pie

I pulled all the aftermarket parts out. We scrapped the blow bars (they were already damaged). I ordered a full set of genuine Kleemann OEM parts from the local dealer.

Cost: $4,100 (filters and liners included).

But wait—that’s less than the original OEM quote? Yeah. The original quote was for a larger quantity. I’d been so focused on the “savings” of the aftermarket that I’d dismissed a revised OEM quote that was actually competitive. (Should mention: the OEM dealer offered a bulk discount on the EVO-specific blow bars if we committed to two sets. I’d ignored it.)

The genuine parts installed perfectly. The crusher ran smoother. The blow bars lasted about 170 hours before needing replacement—better than the OEM spec of 150 because the material we were crushing was relatively soft limestone. The aftermarket bars wouldn’t have lasted 100 hours, even if they’d fit.

The total cost of the mistake: $3,200 for the aftermarket parts (wasted) + $4,100 for the correct OEM parts = $7,300 spent to get a working crusher. Plus three days of downtime during the swap and inspection. Plus the embarrassment of explaining to the project manager that I’d tried to save $1,900 and ended up spending $2,200 more than the OEM option I’d rejected.

The Broader Lesson: When to Stick with the Specialist

I’m not a crusher engineer. I’m a parts procurement guy who’s learned through expensive trial and error. I’d rather work with a specialist who knows their limits than a generalist who overpromises.

This experience taught me a simple rule that I now apply to any major equipment purchase:

  • For generic components (filters, belts, standard fasteners): Aftermarket is fine. No one needs a Kleemann-branded oil filter.
  • For wear parts that affect machine dynamics (blow bars, jaw dies, rotor components): Stay with OEM unless the aftermarket supplier can prove they’ve reverse-engineered your specific model, not just the series.
  • For anything related to the EVO platform: Honestly, just go OEM. The engineering changes between generations are subtle enough that generic parts are a gamble.

The vendor who says, “That’s a Kleemann EVO 2—our standard blow bar won’t work on that rotor” is the one I trust. The vendor who says “Oh yeah, it fits everything” gets a second look, a third question, and then a polite “no thanks.”

So, Why Is It Called Breakfast?

You might be wondering about that last SEO keyword: “why is it called breakfast.” Honestly, I’m not 100% sure how it fits this article, except that it’s a classic example of the random search terms people use when they’re looking for something specific but don’t know the technical name. (Should mention: I spent ten minutes trying to figure out if “breakfast” was some obscure mining slang. It’s not. It’s just what happens when keyword research meets autocorrect.)

If you’re searching for “Kleemann” and “breakfast,” my guess is you’re trying to find the Kleemann Second Congress—an industry event that sometimes gets garbled in translation. Or maybe you heard the word “Miranda” (a common name for conveyor belt suppliers) and it stuck. Either way, I’ve learned that the internet is full of weird search queries, and sometimes the best answer is “I don’t know, but here’s what I do know about avoiding a $3,200 mistake.”

Final Thoughts

That mistake happened over two years ago. I’ve caught 11 potential errors since then using the checklist I built from that failure. Every time I get a quote for aftermarket parts, I run it through the same three questions: “Does the supplier have EVO-specific data? Have I verified the OEM price? Am I trying to save money, or am I trying to save money safely?”

The answer is almost always OEM for parts that touch the rock or the rotor. And that’s not because Kleemann is the only option—it’s because when you’ve seen what a 3mm gap can do, you stop gambling on “good enough.”
