Dozer Inspection

Dozers are one of the most common machines you see on all the major construction, mining or forestry projects across Australia. We have also seen an increase in suppliers which are hiring dozers for long term or purchasing used dozer for their fleet.

To ensure that you hire or buy the right used dozer for your project we have come up with a simple 7 step checklist of what you should look for when inspecting a dozer for hire or purchase.

The 7 steps to inspecting a dozer include:

  1. Dozer operational history
  2. Wear and tear of the dozer
  3. Inspecting the undercarriage
  4. Check plate lines or welding
  5. Hydraulic system and engine
  6. Cab and general inspection
  7. Attachments and tech upgrades

Dozer operational history

When looking at the dozers operational history you should consider a couple of factors. These include the machines operation hours, year, price and condition. This will assist you in your decision making as it great guide to the use of the dozer.

Wear and tear of the dozer

As identified in the history of the dozer through the operational hours and year this is a great indicator of the general wear and tear of the dozer. As your walk around the dozer look for signs of damage or wear and tear to the top of the blade, cutting edge and the spill guard. Additionally check the blade push arms and inspection the trunnion pins and caps. If the trunnion cap is loose this is a great sign that it has excessive wear.

Inspecting the undercarriage

As the undercarriage is seen as 20% of the dozer’s value, it can be quite costly to repair, so it is vital to be inspected accordingly. When inspecting the undercarriage of the dozer some of the key things to look for include:

  • Uneven wear of the undercarriage as the operator could favour steering in one direction over the other
  • Uneven wear due to dozer being constantly run on a hillside
  • Tops and bottoms of the brushing - by reaching over the rails and touching tops and bottoms of the brushing you will be able to determine in what condition they are. If the dozer is in top condition the bearings should be round. If the bearings feel flattened in areas, it generally is a sign of excessive wear
  • Track pads and its thickness - if the grouser bar is the same height as pad bolts, then the track pads will need to be replaced

Check for plates lines or welding

To determine the excessive wear inspect the dozer blade noting any plate lines as this could mean the blade has been refaced to cover up the excessive wear. Additionally checking the blade for signs of welding as this could also be an indicator that it has gone some repairs.

Hydraulic system and engine

When it comes to inspecting for any damages to the hydraulic system and engine it is important to look for signs of leakages and check the fluids, lose belts and dirty filters.

Gab and general inspection

When it comes to inspecting the cab inspect the condition of the ROPS, seat, seat belt, floorboard and instrumental panels ad control. If the dozer has enclosed cab examine the doors, glass and latches. Additionally, inspect the state of the steps, handrails and mirrors. If not expected and damaged this will all add unnecessary costs for you to fix.

Attachments and tech upgrades

Attachments and tech updates generally add value to the dozers as long as they are in good condition. Some of the attachments you could come across when inspecting a dozer include:

  • Rear attachments - single-shank or multi shank ripper or auxiliary hydraulic
  • Productivity and safety features - camera system, GPS or monitors.
