I recently purchased this 3500hr machine. The engine was low on compression - approx 180psi across all 3, so a new engine was needed.
I picked up a 3TNV82a which was out of a truck refrigeration unit. Engine appears strong so I swapped it over. Some minor hurdles were encountered, the biggest being the flywheel needed machining to fit the larger diameter crank end.
The new engine in the 3TNV which i've read has improved emissions, better injectors etc etc. Does anyone see any issues running the 'generator' engine in the excavator? I enquired with Yanmar (japan) and they came back saying not to install it as the governor is not suitable. i've hooked up an accelerator cable to it and the revs are adjustable. It does seem to 'lag' a bit when changing revs. Is the governor designed to sit at just one rev all the time VS what the excavator will be doing.
Although the old governor would easily bolt up, it wont pump up to the new type injectors and head design is also different.
Any thoughts would be appreciated!
Engine removed was 3TNE82-A-EBVC
New engine is 3TNV82A-GG
