How often should hydraulic oil be changed?

It depends on the machine, the oil, the hours and the operating conditions. We work to the manufacturer guidance and what the oil and filters actually show.

Can you service our machines on site?

Often yes, subject to the job, your location and current workload. Call 09 430 8070 to talk through a schedule.

Do you keep records of what was done?

Yes. You get a summary of what was checked, what was replaced and what we recommend planning for.

Can you set up a servicing schedule for a small fleet?

Yes. Tell us the machines and how they are used and we will work out sensible intervals with you.

What if you find something serious during a service?

We tell you straight away, explain the options and let you decide whether to deal with it now or plan it in.

Machinery Maintenance and Servicing in Whangārei

Most hydraulic failures give warning long before they stop the machine. Scheduled servicing and system health checks catch wear, leaks and contamination while they are still small, so the repair happens when you choose rather than mid-job.

Workshop vs on-site

Routine servicing, oil and filter changes and inspections can often be carried out on site.

Anything the inspection turns up that needs machining, rebuilding or line boring comes back to the Whangārei workshop. On-site availability depends on the job, your location and current workload.

What you get out of it

Fewer surprise failures during the jobs that matter
Repairs planned into quiet periods instead of peak work
A clear record of machine condition over time

Equipment and industries

Excavators, loaders, tractors, tippers, trailers, truck-mounted cranes, waste and vacuum trucks, forestry gear and fixed industrial plant.

Most maintenance clients are contractors, transport operators, waste businesses and rural operations around Whangārei and Northland.
