Keeping plant and machinery running across
What we do
All aspects of engineering, under one roof
From precision line boring to full fabrication, machining and breakdown repairs. If it turns, pivots or needs fixing, we sort it, on site or in the shop.
Line Boring
On site or in the workshop. Worn pins, bushes and pivot points bored true and built back to spec so your gear runs tight again.
Linkage Repairs
Bush and pin replacement, line boring and welding on buckets, booms, dozers and loader linkages.
Machining
Lathe and mill work, shafts, sleeves and one-off parts turned to tolerance.
Fabrication
Structural and repair welding, brackets, guarding and custom steel built to suit the job.
Mechanical Repairs
Breakdown callouts and scheduled service to keep plant and machinery in the paddock or on the floor.
Design
Practical design and problem solving when an off-the-shelf part or fix does not exist.
Factory Relocations
Machinery dismantled, moved and set back up with minimal downtime to production.
New Installs
New plant and equipment positioned, aligned and commissioned ready to run.

On site. In spec.
Worn bores machined true and built back so your gear runs tight again.
Line boring in Echuca, on site or in the shop
When pins and bushes wear, holes go oval and your machine gets sloppy and slow. Line boring machines those pivot points back to a true, round bore, so buckets, booms, loaders and dozers run like they should, without replacing the whole component.
On site
Our mobile set-up comes to you in the paddock, pit or yard, so the machine stays put and downtime stays short.
In the workshop
For bigger jobs and full rebuilds, our fully set-up Wharparilla workshop has the gear to get it done right.
- Bush and pin replacement
- Line boring and welding
- Pivot and pin bores brought back to true
- Bores measured and checked to spec

My promise to you
G'day, I'm Sean. After 20 years in the trade, I decided to open SOS Engineering. That is two decades across mining, agricultural, civil and factory work, so there is not much machinery I have not had my hands on.
When you call, you deal with me. Whether it is a breakdown that cannot wait or a scheduled service to catch the small stuff early, you will get a straight answer, honest work, and a fix that holds up.
That is the deal: I look after your gear like it is my own, and I keep you moving.
Great service, keeping you moving.

Based in Northern Victoria, 300km covered
We work out of a fully set-up workshop in Northern Victoria, and our mobile set-up means we cover roughly 300km in every direction, from Swan Hill and Deniliquin through to Albury, Wagga Wagga, Griffith and up toward Hay. On farms, sites and factory floors right across the border region.

Common questions
Line boring machines worn pivot holes, pins and bushes back to a true, round bore. It is how you bring excavator booms, buckets, loader linkages and other pivot points back to spec without replacing the whole component.
