I'm going to say something that might get me in trouble with some folks: I almost never buy OEM Bobcat parts anymore.
When I first started managing our equipment fleet six years ago, I assumed OEM was the only safe bet. "Original Equipment Manufacturer" – how could you go wrong? I was dead wrong. After tracking $180,000 in cumulative spending across our maintenance records, I learned that OEM parts cost us about 40% more on average, with no measurable difference in lifespan for most components.
What the Bobcat Online Parts Catalog Doesn't Tell You
The Bobcat online parts catalog is a great tool for finding part numbers. But here's the thing – it's also a pricing trap if you're not careful. The catalog shows OEM list prices, but it doesn't tell you that many of those same parts are made by third-party manufacturers and sold for a fraction of the cost.
Take our skid steer loaders. We needed a hydraulic filter – OEM part was $74 through the catalog. I found the identical filter (same manufacturer, same specs) from a reputable industrial supplier for $22. Same part. Same performance. I called the supplier to verify cross-reference compatibility. As of January 2025, that's a 70% savings on something that gets replaced every 250 hours.
People assume OEM filters are higher quality. Actually, many OEM parts are rebranded from specialized manufacturers. The causation runs the other way: OEMs often buy from the same suppliers you can buy from directly. You're paying for the Bobcat logo and the convenience of a single catalog lookup.
The Bobcat Excavator Controls Diagram: A Costly Rabbit Hole
Last Q2, we had a control joystick issue on a 2018 Bobcat E35 compact excavator. The Bobcat excavator controls diagram in the parts catalog showed an assembly with four sub-components. The OEM joystick assembly: $1,240. A genuine aftermarket replacement from a brand with ISO 9001 certification: $680. The difference? About $560. Enough to buy lunch for the whole crew for a week.
But it gets better. When I opened the OEM assembly, the potentiometer inside was made by Honeywell. The same Honeywell replacement part from an electronics distributor? $45. We replaced just the potentiometer on two machines for $90 total, instead of $2,480 for OEM assemblies. The job took an extra 30 minutes per machine.
Now, I'm not saying OEM is never the right choice. For critical safety components like brake lines or structural parts on a compact track loader, I still go OEM. But for 90% of the items in the Bobcat online parts catalog, there's a quality aftermarket alternative that costs way less.
And What About That Westinghouse Generator You Just Bought?
Here's a tangent that actually connects. We run a Westinghouse generator at our shop for backup power. A few months back, the voltage regulator failed. The Westinghouse dealer quoted $320 for the replacement module. A quick search showed the same module (made by Staco Energy, same OEM supplier) for $110. The parts catalog made it look like a specialized part – but it wasn't.
The pattern is consistent across industrial equipment. Manufacturers want you to believe their catalog is the only source. But with a little digging, you can find the same components – often cheaper, sometimes with better warranties – and your equipment runs just fine.
But Wait – What About The "Squatted Truck" Crowd and Air Compressors?
I'll address the obvious counterargument: some people say aftermarket parts are lower quality. And sure, if you're buying the cheapest no-name filter from a random seller, that's risky. But the same logic applies to everything – including your squatted truck (which, honestly, probably needs a better suspension engineer more than it needs OEM parts).
Here's a practical rule: for any part that's not a safety-critical or high-stress component, use aftermarket. Filters, belts, electrical components, sensors, most hydraulic components – all fair game.
And don't get me started on air compressors. A lot of people think they need the dealer-branded compressor for their shop. But what is an air compressor really? It's a motor driving a pump. If you know the specs (CFM, PSI, tank size), you can buy from a company that specializes in compressors, not from an equipment dealer that marks everything up by 30%.
The Bottom Line: An Informed Customer Makes Better Decisions
Look, I use the Bobcat online parts catalog all the time. It's great for part numbers and diagram reference. But I stopped treating it as a shopping cart years ago. After six years of tracking invoices and comparing prices across vendors, the data is clear: OEM parts are a convenience tax you don't have to pay.
An informed customer asks better questions. I'd rather spend 15 minutes cross-referencing a part number than pay a 40% premium for a logo. Take it from someone who has audited $180,000 in parts spending – your equipment doesn't know the difference, but your budget certainly does.
