How a repair moves through our shop, in eight steps

Every job follows the same route: it starts with your first call and ends with a component or machine that has been tested and put back to work.

01

Collection

Where it applies, we arrange to collect your equipment or component at no charge.

02

Hands-on inspection

The unit is stripped down so the whole failure can be assessed properly.

03

Photo and video record

We record the condition and everything we find, so the repair discussion rests on evidence.

04

Written repair quote

Before any work goes ahead, we spell out what we recommend and price it for you.

05

Your go-ahead

Together we settle the scope, the urgency and the most sensible way forward.

06

Machining and making parts

Any part the job needs is machined, welded, rebuilt or reverse-engineered right here.

07

Bench testing

Nothing is released until its operation and the standard of the work have been checked.

08

Return delivery

The finished component or machine heads back to you, ready to go to work again.

Questions customers ask us most

Which hydraulic components do you rebuild in-house?

Cylinders, pumps, motors and final drives — covering trucks, heavy equipment and industrial systems, and every one of them is rebuilt under our own roof.

My cylinder is leaking — will a reseal do the job?

A reseal only works when the rod, the bore and the gland all still measure inside specification. We take those measurements and share them with you; where the metal has worn, fresh seals on their own will not last.

What makes a boom or bucket creep downward under load?

In most cases oil is slipping past inside the cylinder, or bypassing at the control valve. Running a drift test tells us which one it is before you spend anything on parts.

Can you rebuild the drive motors on a track loader?

Yes — rebuilding drive motors and final drives is one of the things this shop is known for.
