CAT C15 Service Exchange
Rebuilt CAT C15 engines, ready to swap
Need a reliable replacement engine without long downtime? Bring in your old or worn C15 and we can swap it for a rebuilt exchange unit.
Walton Mechanical Group supplies fully rebuilt Caterpillar C15 service exchange engines from our Bunbury workshop. The aim is simple. Reduce downtime, avoid a long rebuild wait, and get your asset back earning sooner.
If you are searching for a CAT C15 engine rebuild in WA, a Caterpillar C15 replacement engine, or a service exchange C15 engine for a truck or heavy asset, speak with Trent about availability before the job becomes a production problem.
How service exchange works
Bring your old or worn C15 engine to us and we swap it over with one of our rebuilt exchange units, subject to availability and assessment. We can organise a float to pick up, and workshop installation is available through our heavy diesel team.
Built for operators who cannot wait
Waiting on a full rebuild from scratch can keep a working asset out of the cycle for too long. A rebuilt exchange unit gives you a faster path back to work, backed by heavy diesel mechanics who understand how expensive downtime gets on mining, civil and transport work.
Our rebuilds include
- Fully stripped and inspected engine
- Block, crank, cam and head machined back to OEM spec
- New bearings, seals and gaskets
- Reconditioned cylinder head
- Replaced liners and pistons
- Every component sandblasted and painted
- Brand new CAT auxiliary parts replaced
- Workshop fitted by Walton Mechanical Group
Who this suits
- Operators with a failed or worn Caterpillar C15 engine
- Truck, plant and heavy asset owners trying to avoid extended downtime
- Mining, civil and transport businesses that need a faster replacement path
- Workshop jobs where pickup, installation and rebuild accountability matter
Why operators use exchange units
A full engine failure can take a machine out of the production cycle at exactly the wrong time. A service exchange unit gives you a faster path back to work than waiting on a complete rebuild from scratch.
- Fast turnaround times
- Less costly downtime
- Experienced heavy diesel mechanics
- Competitive pricing

Common questions
Is availability guaranteed?
No. Service exchange depends on current rebuilt unit availability and assessment of the old engine. Call first so Trent can confirm the path.
Do you only work on CAT C15 engines?
No. Walton Mechanical works across heavy diesel equipment and multiple earthmoving makes, but this page is specifically for the Caterpillar C15 service exchange offer.
Can the engine be installed at Walton Mechanical's workshop?
Yes. Workshop installation is available at our Bunbury workshop, and pickup support can be discussed when you enquire.
