About TMS Oz
Specialist Workshop, Built in WA.
Heavy equipment repairs, maintenance and performance solutions — founded in 2018, owned and operated in Western Australia.
Who We Are
A Workshop That Earns Its Keep.
TMS Oz is a Perth-based heavy equipment workshop, founded in 2018 by Tommy McErlean and operated 100% in Western Australia. We deliver repairs, maintenance and performance solutions for civil, construction and mining operators — from major workshop rebuilds to scheduled servicing and ECU remapping.
We built the business around the kind of workshop operators wish their last shop had been: honest hours, real diagnostics, and a phone that actually gets answered. Direct access to senior techs, work done to OEM standard, and the kind of straightforward communication procurement teams and foremen both appreciate.
We work to OEM standards using genuine and approved parts, back our work in writing, and bring the kind of straight-talking, no-shortcuts approach operators expect from a team that’s been on the tools — not behind a desk.
What We Stand For
Principles That Don’t Budge.
To keep Australia’s heavy machinery in service through honest workmanship, technical precision and the kind of relationships built on doing what we say.
01
Workmanship
Repairs done to OEM standard the first time. No shortcuts, no patch-jobs. Every job is one we’d put our name on.
02
Partnership
We work alongside operators, foremen and procurement teams. Clear communication, honest reporting, no surprises on the invoice.
03
Response
Equipment down means money lost. We move fast to get fleets back in service when it matters.
04
Expertise
Heavy diesel, hydraulics, electrical and ECU tuning under one roof. Specialist tooling, factory-level diagnostics, real depth of knowledge.
