You can tell it is time to perform an overhaul on any Caterpillar equipment based on three things:

  • Oil consumption
  • Fuel consumption
  • Regular maintenance schedule

Most Caterpillar equipment owners track their scheduled and unscheduled maintenance performance tasks very carefully. If they don’t then serious malfunctions and equipment failures can occur due to the equipment not receiving the proper care. Any changes in the way that the equipment is running can be determined pretty fast by charting all of this information and reviewing it regularly. Caterpillar equipment operators are usually trained to pay special attention to fuel mileage and oil pressure while they are driving. If it seems that the equipment is burning through more oil and fuel on a regular basis then it might be time for an overhaul to be done.

Getting the Right Parts

When beginning an overhaul, it is important to remember that a lot of the same parts can be reused to save money, but you can’t salvage all of them. Some heavy equipments used parts can be bought online. Others you will have to purchase new at Caterpillar equipment dealers. To avoid having to run back and forth for parts, make a list of what you need before you go. Try to bring as much information with you about the Caterpillar equipment as you can. It will make the Caterpillar part number search much easier. There are some parts that can generally be bought used or rebuilt and some that you should always buy brandnew to avoid further damage from occurring.

Acceptable Used or Rebuilt Parts:

  • Cylinder heads
  • Oil pumps
  • Fuel pumps
  • Cam followers
  • Oil coolers

Parts That Should be Purchased New:

  • Seals, o-rings, gaskets
  • Any kind of bearings
  • Pistons rings
  • Rods
  • Pistons

Save What Parts You Can

Of course, if any of the parts are not damaged, it is unnecessary to replace them, but it is often wise to install new parts during the overhaul because everything is disassembled already. Sometimes, it can actually save time and money to invest a little more into the overhaul now rather than waiting until it breaks down.
