McCloskey Equipment FAQ: Crushers, Screeners, Stackers, and Costly Lessons

This page is a McCloskey equipment FAQ, but I need to get one thing out of the way first. I can't help with Jay McCloskey OxyContin, Dr. McCloskey Tyler TX, Eddie near me, or Jonah Vice. I'm not that McCloskey. I write about the McCloskey that makes mobile crushers, screeners, and stackers. And yes, I can help with the best tires for a McCloskey stacker because I learned that lesson the expensive way.

I've been on the buying side of this industry since 2010. In that time I've personally made and documented seven significant equipment mistakes, totaling roughly $120,000 in wasted budget. Now I maintain our team's pre-purchase checklist so I don't have to keep learning the same lessons. This FAQ is that checklist in article form.

What is McCloskey equipment, exactly?

McCloskey International makes mobile crushing and screening equipment for quarries, recycling, mining, and construction. You'll see their name on jaw crushers like the J50v2, screeners like the R230, and stackers used to build stockpiles. The equipment is designed to move between sites, which is why most buyers care about transport dimensions, setup time, and tire ratings.

From the outside, it looks like any yellow machine. The reality is that the brand's real value shows up in parts availability and dealer support when something breaks. That's the part nobody quotes on the purchase order.

What McCloskey J50v2 specs should I check?

The J50v2 is the McCloskey jaw crusher we get asked about most. The headline spec is the 50-inch by 29-inch jaw opening. After that, the specs that matter are the feeder size, pre-screen, conveyor width, and engine package. Emissions rules changed over the years, so a J50v2 built for Tier 4 will not have the same engine setup as an older Tier 3 machine.

One mistake I made early on: I asked for a J50v2 and assumed the spec sheet I found online would match the unit I was buying. It did not. The older unit had a different pre-screen. Nothing showed up on the site inspection because I never asked for the serial-number-specific spec sheet. That error cost us roughly $3,400 in added conveyor work and a two-week delay.

If a dealer sends you a J50v2 spec sheet, ask for the unit's serial number and the exact build date. I want to say the current hopper capacity is around 10.5 cubic yards, but don't quote me on that. Verify it against the machine you're actually buying.

What are the McCloskey R230 specs?

The R230 is a high-energy screener, not a crusher. The McCloskey R230 uses a 20-foot by 6-foot screen box in a double or triple deck configuration—I think that's the current number, but verify the build sheet because McCloskey changed options over time. The screen size, stroke, and speed matter for production, but feed prep matters more. If a dealer quotes R230 specs without asking what you're screening and what size you're feeding, that's not the right dealer.

I have mixed feelings about R230 specs in isolation. On one hand, comparing screen area is useful. On the other hand, the best screen on paper can still struggle with wet material or poor distribution. Run your own material, not just the brochure.

What should I check before buying a used McCloskey stacker?

Used stackers can be a good value, especially when a McCloskey stacker for sale listing comes from someone upgrading to a longer radial unit. But the cheap part is the sticker price. The expensive part is what you don't check.

Here's my non-negotiable list for a used stacker: belt condition, idler condition, hydraulic drive, brakes, frame welds, axle rating, tire rating, and the actual maintenance records. I once ordered a used stacker and focused only on belt width. The tires were old and under-rated for the axle load. The first loaded run caused a sidewall failure. It cost $2,300 for a service call and new tires, plus a week of downtime.

Three things to verify before you sign: belt thickness, frame welds, and tire rating. In that order.

What are the best tires for a McCloskey stacker?

People ask about the best tires for a McCloskey stacker more than you'd expect. The answer is not a brand. It's a rating. The best tires are the ones rated for the actual axle load of the loaded stacker, with enough ply rating for the speed and haul distance on your site.

We run 14-ply trailer tires on our 36x80 stacker. I'm not saying that's the right spec for every site, because site conditions and transport distances matter. But I am saying this: don't buy the cheapest 8-ply tires because they fit the rim. That was the mistake on the used stacker I mentioned above.

Why does this matter? Because a tire failure on a loaded stacker isn't just a breakdown. It's a safety issue. Verify before you buy, not after the first blowout.

How much does McCloskey equipment cost?

Based on public dealer listings I've tracked on MachineryTrader.com, a used McCloskey J50v2 has been advertised in the range of $275,000 to $425,000, depending on hours and condition, as of January 2025. A new McCloskey stacker is a different number; I'd rather not throw out a fake exact quote. Ask for written quotes from at least two dealers.

Here's the thing: the purchase price is not the cost. Freight, commissioning, training, wear parts, and downtime risk all hit the total much harder. I've learned to ask 'what's NOT included' before 'what's the price.'

The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end.

In Q1 2025, we asked three dealers to quote the same McCloskey stacker configuration. The gap between base price and installed price ranged from 8% to 19%. The lower base price had more excluded items. That's not an attack on any dealer. It's why we now compare total installed costs, not machine prices.

Where do I find McCloskey parts and service support near me?

Use McCloskey International's dealer locator to find the nearest authorized dealer. But don't wait until the machine is down to call. I thought we had parts support covered through a local dealer. Then a bearing failed and the earliest delivery was three weeks. We now keep a small stock of critical wear parts and have a backup dealer ready.

The best field tech we ever worked with was named Eddie. He always seemed to be nearby when we didn't need him and retired the month we actually needed him. Since then, I've learned to ask about response times and emergency coverage before buying a machine. If you're searching Eddie near me because your local Eddie knows your old stacker, I feel you. Write down everything he knows before he leaves.

Should I buy a McCloskey machine new or used?

There's no universal answer. New McCloskey equipment gives you a warranty, current emissions compliance, and a clean maintenance history. Used equipment can save money upfront, especially if you get a stacker or screener that hasn't worked its whole life in abrasive material.

But used only makes sense if you inspect it with a checklist and include realistic replacement costs in your budget. In 2022, I bought a used screen at what looked like a great price and then spent nearly $14,000 on new bearings, belts, and screen media before it produced a single ton. That machine was not cheaper. It was just cheaper on the day I signed.

If you want the one piece of advice I pass to every new team member: ask about everything that isn't on the quote. Then write it down. That simple habit has saved us more money than any negotiation I've ever run.
