McCloskey Gear: A Buyer's Guide (From Someone Who's Messed Up More Than Once)

Let me start with a confession: when I first started handling equipment parts for our quarry, I thought I had it all figured out. I was wrong.

I've been handling parts orders for McCloskey equipment for about 7 years. In that time, I've personally made (and documented) a dozen significant mistakes, totaling roughly $8,000 in wasted budget. Now I maintain our team's checklist to prevent others from repeating my errors.

This article answers the questions I wish I'd had answered before making those mistakes. Let's get into it.

1. What's the most common mistake people make when ordering McCloskey parts?

Assuming the part number is universal.

When I first started ordering for our S190 trommel screen, I assumed that if a part looked right in the diagram, it was the right part. Incorrect. The same machine can have multiple revisions. A 'bolt kit' from a 2018 model is different from a 2020 model's kit.

I once ordered 20 screen panels for the wrong deck—they were identical in the manual's image but had different tensioning mechanisms. That error cost $890 in redo shipping plus a 1-week delay.

Always verify the serial number and machine year before you hit 'order'.

2. Is it worth paying for rush delivery on McCloskey parts?

Yes, if downtime is costing you money.

I used to think expedited shipping was a scam—just vendors gouging customers. Then our 621 trommel went down during peak season. The 'standard' lead time was 10 business days. Rush delivery was $400 extra. The alternative? A week of downtime on a machine that was grossing $2,000 a day.

The math wasn't complicated. We paid the rush fee. The part arrived in 3 days.

In March 2024, we paid $400 extra for rush delivery. The alternative was missing a $15,000 event. The value of guaranteed turnaround isn't the speed—it's the certainty. For keeping a machine running during a contract deadline, knowing your delivery date will be met is often worth more than a lower price with 'estimated' delivery.

3. Can I use aftermarket parts for my McCloskey C3 cone crusher?

Sometimes. But be careful.

Honestly, I've never fully understood the blanket answer to this. My experience suggests it depends on the component.

For wear parts—liners, screen media, conveyor belts—aftermarket options can be just as good as OEM, often at 60-70% the cost. We've had great luck with aftermarket liners for our C3 cone. But for hydraulic components, electronics, or precision-engineered parts like the main shaft assembly? Stick with McCloskey OEM.

The conventional wisdom is that aftermarket voids warranties. In some cases, that's true. But if your machine is out of warranty, you have more flexibility. Get a spec sheet from the aftermarket supplier and compare it to the OEM part's specifications.

4. How do I find the right part number for my McCloskey R230 screener?

This is where I made my second-biggest mistake. I used to rely on online manuals alone.

Here's my process now:

• Step 1: Find the machine's serial number. It's usually on a plate near the engine or on the chassis.
• Step 2: Contact your local dealer with the serial number. They can confirm you're looking at the right revision.
• Step 3: Cross-reference the part number in the official parts catalog.
• Step 4: If possible, take a photo of the worn part and send it to the dealer. This has saved me twice.

I should add that dealer networks vary. Some are fantastic. Some... less so. If your local dealer isn't helpful, try another. (Should mention: McCloskey International's website has a 'Find a Dealer' tool, but it's not always perfectly updated.)

5. What's the 'Simparica for Dogs' connection?

Wait—this isn't a medical article. Obviously.

If you landed here searching for 'Simparica for dogs'—that's a flea and tick medication for pets, not a piece of McCloskey equipment. Just to clarify.

This is the classic SEO keyword collision problem. Search engines sometimes get confused, and you end up on a heavy equipment parts guide when you wanted veterinary advice. Sorry about that.

If you're a pet owner, you're looking for simparicaformen.com or similar. If you're in the aggregate industry, keep reading.

6. Is the McCloskey shredder worth the rental fee?

For specific jobs, absolutely. For general bulk processing, maybe not.

In July 2023, we needed a shredder for a forestry waste project. The McCloskey shredder was available through a rental yard. The rental rate was high—around $1,800/day—but it processed 500 tons in 3 days. A competitor's shredder was available for $1,200/day but was slower and had more downtime.

The question isn't just the rental fee. It's the cost per ton of output. On paper, the cheaper option looked better. In practice, the McCloskey's higher throughput meant lower total cost for our specific job.

Total cost of ownership includes:

• Base rental price
• Fuel consumption
• Throughput rate
• Operator skill required
• Potential downtime

7. Should I buy a used McCloskey J44 jaw crusher or a new one?

I'm not a financial analyst, so I can't speak to return on investment calculations. What I can tell you from a maintenance perspective is the maintenance history matters more than the hour count.

I once bought a used crusher with 4,000 hours on it. Looked great on paper. Good price. But the previous owner had only performed basic maintenance—no major overhauls. Within 6 months, we needed a new jaw die set and a main bearing. $12,000 in repairs we hadn't budgeted for.

If I remember correctly, the rule of thumb is to budget 10-20% of the purchase price for immediate repairs on used equipment. You'll likely need it.

8. How do I maintain a McCloskey pugmill system for longevity?

This gets into chemical exposure territory, which isn't my strongest area. I know enough to say corrosion is the enemy.

Our pugmill handles lime and fly ash. The wear on the paddles and liners is constant. Here's what works for us:

• Daily washdown after use. Non-negotiable.
• Monthly inspection of liner thickness.
• Quarterly replacement of paddle tips.
• Annual bearing inspection.

I'd recommend consulting a McCloskey service manual for your specific model. Don't just guess—you'll end up with corrosion damage that costs you more in the long run.

Hopefully, this helps you avoid some of the mistakes I've made. The key takeaway? Verify part numbers, budget for surprises, and never assume 'standard delivery' is fast enough for your downtime. Waste less, produce more.
