In the world of heavy duty diesel engines, performance is everything. Whether you’re hauling freight across Australia’s unforgiving terrain or managing a fleet of trucks on tight deadlines, engine reliability isn’t negotiable. It’s survival.
That’s why smart operators trust AJK Engines and their Cummins X15 Premium Exchange Engine Package.
This isn’t just an engine rebuild. It’s a complete, professionally assembled, road ready solution backed by precision craftsmanship, cutting edge parts, and a 12 month unlimited kilometre warranty.
Here’s what sets this package apart and why it could be the smartest investment you’ll make for your Cummins powered machine.
Built by Professionals Who Know Cummins Inside Out
Let’s be honest. Not every engine reconditioner gives your Cummins the respect it deserves. At AJK Engines, this isn’t just another job. It’s an engineering standard.
Each Cummins X15 engine is:
-
Stripped down and rebuilt in house by trained specialists
-
Crack tested, chemically cleaned, machined, and measured with laser accuracy
-
Reassembled to Cummins factory specifications or better
The result? You’re not just getting a used engine. You’re getting a powerhouse built to perform like new, engineered for long term reliability and fuel efficiency.
What’s Included? Every Critical Component Rebuilt or Replaced
AJK’s Cummins X15 Premium Exchange Engine Package doesn’t cut corners. Instead, it replaces or refurbishes every key system in your engine.
Here’s a breakdown of what goes into your reconditioned Cummins X15 engine:
Engine Block and Crankshaft
-
Block is crack tested, chemically cleaned, machined where required, and painted
-
Crankshaft is cleaned, crack tested, and linished or replaced with a new one
-
New main and conrod bearings, bolts, wrist pins, pistons, and rings are installed
-
APR upgraded cylinder liners provide improved durability and performance
This ensures the heart of your engine, the rotating assembly, runs smoother, cleaner, and longer.
Oil System Fully Rebuilt for Maximum Protection
-
Brand new oil pump and seals
-
New crankcase filter
-
Rebuilt oil filter module featuring a new oil cooler and oil thermostat
This keeps your engine cool under pressure and protected from friction based wear, even in Australia’s harshest conditions.
Cylinder Head Reconditioned or Brand New
No more guesswork. The cylinder head is either fully reconditioned or replaced outright if it doesn’t meet AJK’s stringent standards.
The reconditioning includes:
-
Machining
-
New valves, seats, and springs as needed
-
New valve stem seals, injector cups, and cam bearings
-
Crack and pressure tested for absolute integrity
Your combustion system is built to handle full load, high performance, and everyday demands.
Fuel and Air Systems New Injectors, Turbo, Air Compressor and More
-
6 brand new diesel injectors with o rings
-
New or remanufactured high pressure fuel pump
-
New or remanufactured turbocharger and air compressor
Fuel delivery and forced induction are crucial to the Cummins X15’s high output capabilities. With these replaced or reconditioned, your engine breathes and feeds like it’s fresh from the factory.
Valve and Brake Components
AJK doesn’t just make your Cummins run. They make it stop when it should.
-
New valve and injector camshafts
-
Refurbished rocker levers
-
New Jacobs brake overhaul kit
-
New Jacobs brake harness
This gives your vehicle strong and reliable engine braking power, especially useful for hauling heavy loads or navigating steep terrain.
Cooling and Timing Systems
Heat and timing. Two things that can make or break an engine. Your Premium X15 package also includes:
-
New coolant thermostat and pump
-
New timing case and flywheel housing gaskets
-
Refurbished or new timing gears and thrust washers
You’ll get consistent cooling, efficient timing, and reduced mechanical stress from the get go.
Seals, Filters and Finishing Touches
Every engine package is buttoned up with:
-
New head gasket and bolts
-
New crankshaft seals front and rear
-
New oil filter, coolant filter, and fuel filters
-
New oil pan gasket
-
Flywheel machined and fitted with a new spigot bearing
And yes, it’s fully timed, primed, and filled with semi synthetic engine oil before it even leaves the shop.
Painted Red, Built to Run
Every engine is prepped and painted Cummins red, giving you that fresh, ready for duty look and feel. AJK doesn’t just build engines. They build confidence.
Warranty That Works for You
This isn’t just a service. It’s a promise. Each Cummins X15 Premium Exchange Engine comes with a 12 month unlimited kilometre warranty. No fancy asterisks. Just straight up coverage (conditions apply, of course).
It’s peace of mind for truckies, fleet managers, mechanics, and logistics operators who can’t afford downtime.
Exchange Basis: How It Works
The engine package is sold on an exchange basis, which keeps prices more affordable and parts in circulation.
Here’s how it works:
-
You provide your used Cummins engine core in exchange
-
If no exchange is offered, additional core charges apply
-
If any part of your core is unserviceable, charges for replacements apply
It’s a fair system and one that ensures quality, traceability, and sustainability in every transaction.
Not Just Engines Parts and Accessories Too
Looking for individual parts? AJK Engines stocks a wide range of used and reconditioned Cummins parts. From turbos to cylinder heads, all parts are tested, cleaned, and sold on an exchange basis.
