We’ve worked on enough K200s and heavy trailers to know where to look and what can cost you money after you drive it away.

If you’re spending big money on a truck and trailer combination, get it checked properly before you buy it.

We’ve got the experience to help make sure you don’t buy a lemon.

Be smart. Give us a call before you buy.

Buying machinery interstate?

We’ve got you covered.

Our customer was based in South Australia, while this pneumatic roller was located in Newcastle. We attended the machine on their behalf and completed a thorough pre purchase inspection before they committed to the purchase.

Pneumatic rollers require more than just a basic mechanical check. Our inspection included testing the wheel spray system, tyre self inflation and deflation system, general operation, hydraulics, steering, brakes, and overall machine wear.

When you’re buying specialised equipment, use an inspector who understands how it should operate.

Trust Impact Pre Purchase Inspections to help you buy with confidence.

Valve adjustments are an important part of preventative maintenance, especially on engines running unit injectors and engine brakes.

A correct overhead set helps with:
Smoother running
Better engine brake performance
Correct injector operation
Reduced valve train wear
Improved efficiency and reliability

We recommend carrying out a valve adjustment every 100,000 km on a Mack/Volvo to keep everything operating as it should.

Preventative maintenance now can save expensive repairs later.

We recently carried out a pre purchase inspection on this Komatsu WA320-8 loader.

A machine like this is a big investment and an inspection before buying can help identify wear, leaks, mechanical concerns, safety issues and future repair costs before the purchase is made.

At Impact Diesel Group we inspect a wide range of heavy vehicles and machinery, including trucks, trailers, earthmoving equipment and plant machinery.
