A machine sitting idle on a job site isn't just inconvenient — every day it's down is a day of lost work and money left on the table. That's usually when the phone calls start: "Do you have a C7.1? We need it yesterday."
We're SWAFLY MACHINERY CO., LIMITED, based in Guangzhou, and keeping Cat engines on the shelf is a big part of what we do. Right now our stock covers the models most of our customers ask for: C2.2, C4.4, C7.1, C9.3B, C13, C15, and C18.
These are engines we actually have on hand — not a "we'll order it in for you" promise. We'd rather tell you straight what's real than quote you something we can't ship. (Trade terms: EXW Guangzhou.)

The smallest of the bunch, but don't sleep on it. It goes into compact gear where space is tight and you just need it to fire up every morning. We mostly move these as complete assemblies, matched to whatever config you're running.
Probably our most-asked-for four-cylinder. It's forgiving on maintenance and fits a huge range of machines, which is why shops keep coming back for it. Before you order, grab the machine model and serial number — saves us both a wrong-shipment headache.
Steps the power up for mid-size and larger equipment. Configs and auxiliaries vary a lot between applications, so we always match the unit to your machine before it leaves the warehouse. No guessing.
Built for the jobs that don't quit. If you're running one of these hard, send us the machine model, serial, and your current spec sheet, and we'll confirm the exact arrangement.
A workhorse across construction and industrial sites. Tell us the model, serial, or even just a part number and we'll dig through what we have and quote you properly.
Another heavy-duty favorite. This is where accessories, mounts, wiring, and fuel setup really start to matter — two machines with the same badge can sit on completely different plumbing. Our sales team checks that against your order, not after the fact.
The big one. High output, long hours, the kind of engine you put in something that's supposed to outlive the operator. We supply these for construction, mining, and industrial replacement work.
Some of you want the whole assembly. Others just need a long block, a bare engine, or a unit with specific accessories already hung on it. Depending on what's in stock, we can usually sort you into one of these:
The one thing that saves everyone time: send us the machine model, engine model, serial number, arrangement number, or original part number. The more we have up front, the less chance of a compatibility misfire later.
We don't quote off a model number alone. We go look at what's actually on the shelf and what config it's in, then tell you what we can really supply and what it'll cost. That's the difference between a quote you can plan around and a quote that falls apart two weeks later.
And when something's urgent — a machine down, a deadline breathing down your neck — having stock in-house means we can sometimes turn an order around faster than anyone quoting from a catalogue.
We sell to dealers, repair shops, equipment owners, and parts distributors across a lot of different markets. Before anything moves, we confirm the spec, the accessories, and how you want it packed. Engines get crated properly for international freight — we've seen what rough handling does to a bare block, and we're not shipping you a dented surprise.
If you've got a Cat engine you need, send the model and whatever numbers you have. We'll check the shelf, send photos, and come back with a real price and a realistic lead time.
