365C L and 385C L: owner reports

Sources: 3 forum discussions about the Caterpillar 385 mass excavators (385B, 385C); heavyequipmentforums.com.
  • Boom drift, and a buyer's worry about cracked booms. A 385B that would not lower the boom when the bucket was stalled fully in (a reply suspected oil not draining from a spring chamber), and a 2013 thread where a buyer comparing a used 385 with a Hitachi 800 said the older Cat 385 booms seem to be cracked. That is one owner's impression in one thread, not an established fault. The third thread is photographs of a modified 385C. Threads read: 1, 2, 3.
