History and service record of 375, 385B, and 385B L

Built for the reach and the truck. Caterpillar's Specalog for the 375 and 375 L describes a track-type undercarriage designed and built for excavators, reach arrangements that let the owner tailor the digging envelope and lifting capacity, and nine bucket designs covering excavation, extreme-service, mass excavation, trenching and rock work in two bucket families. 375/375 L excavator Specalog AEHQ3850, Caterpillar (copy on idoc.pub).
Engine and pulling force. The Specalog lists a Cat 3406C turbocharged ATAAC engine of 319 kW (428 hp) for the 375, a travel speed of 4.4 km/h (2.7 mph) and a drawbar pull of 546 kN (122,800 lb). 375/375 L excavator Specalog AEHQ3850, Caterpillar (copy on idoc.pub).
One operator's view of the 375. In a Heavy Equipment Forums thread a poster said their company's 375 had been a trouble maker that went through two engines in a year and whose controls felt less responsive than their old 245s; the same poster noted that other members seem to rave about 375s but called them junk. Slightly overkill 375L in action, Heavy Equipment Forums.
Greasing on board. Another poster in the same thread said the 375 he runs has an electric greaser on board, so greasing it is a matter of pulling a trigger. Slightly overkill 375L in action, Heavy Equipment Forums.
Repowering a 375L. A 2016 Heavy Equipment Forums thread started by the owner of a 375L with serial 8XG00304 describes repowering it with an early-2000s 3406E truck engine, using the original throttle assembly to push a potentiometer and keeping the original system to feed the machine computer that controls hydraulics; the owner says his shop has done two 350Ls before, one with a truck engine and one from a farm tractor. Engine options, Cat 375L, Heavy Equipment Forums.
Why a swap is not simple. In the same thread a reply warns that the older Cat engine has an engine-oil-lubricated rear gear train that runs the swing pump among other things, that a 3406B swap some years ago was not straightforward, and that a truck engine would need to be stripped almost to a bare block to fit the correct housings, covers and pans. Engine options, Cat 375L, Heavy Equipment Forums.
