Caterpillar Repair & Service

Excavators, dozers, loaders and backhoes

A Cat 299D3 track loader with its cab tilted up and A/C gauges hooked to the machine

The most common iron on a Bay Area job site, and the machines that stay in service longest. A Cat that has been earning for fifteen years is normal, which means the work is as often wear and structure as it is electronics.

What we see most on Caterpillar

  • Pin bore wear on boom, stick and bucket linkage
  • Undercarriage and ground-engaging wear on dozers
  • Hydraulic drift and cylinder seal failure on older machines
  • Bucket and blade hard facing before base metal is lost
