CAT Excavator Repairs, On Your Site
CAT excavators are the most common machine on South East Queensland civil and earthmoving sites, and the one operators least want to lose. From the 300-series mini machines through the 320, 330 and 336 mid-size class to the larger 349 and beyond, including Next Gen models, we know where these machines wear and what their symptoms usually mean.
OMS repairs and services CAT excavators across South East Queensland: hydraulics, undercarriage, slew and final drives, driveline and the scheduled servicing that keeps wear in the report instead of on the roadside. We come to your job site or yard, so the machine doesn't need to be floated to a workshop.
We're an independent service, and for out-of-warranty machines that's often a good fit. You get experienced, trade-qualified mechanical work at independent rates, with straight answers on what's failed, what it costs and how long it'll take. OMS is an independent mechanical repair and maintenance provider. We are not affiliated with, authorised by, or endorsed by any equipment manufacturer. All brand and model names are used for identification purposes only.

What We See on CAT Machines
Hydraulic Performance
Weak breakout, slow tracking or a hesitant slew on a CAT excavator. We diagnose pump, valve and relief-setting causes before quoting parts.
Pins, Bushes & Linkage
Worn pins, bushes and attachment linkages on a CAT excavator rebuilt so the front end works tight again.
Final Drives
Travel motor and final drive noise, leaks and overheating addressed before they strand the machine.
Undercarriage
Track, roller and idler wear measured and replaced to keep the machine tracking straight.
Electrical Faults
Sensor, display and harness faults that throw confusing symptoms, found and fixed properly.
Scheduled Servicing
Routine servicing on your CAT excavator with oil sampling so wear shows up early, on a planned basis.
CAT Repair Questions
Are you a CAT dealer?
No. OMS is an independent mechanical repair provider and is not affiliated with or authorised by Caterpillar. For out-of-warranty CAT excavators, independent service usually means experienced work at competitive rates, with a more personal service.
Which CAT excavators do you work on?
From the 301–310 mini range through the 320, 323, 330 and 336 mid-size machines to larger 349-class units, including Next Gen models. We cover engine, hydraulic and undercarriage work across the range.
Can you fix hydraulic and final drive faults on a CAT machine?
Yes. Weak breakout, slow tracking, slew hesitation, travel-motor noise and final-drive issues are all common calls. We diagnose to the real cause before quoting parts.
