Picked up a 1990 MEP-002A this past week from GSA.
It’s mounted on a M116A2 trailer.
No clue yet if it runs or makes power but should know by next week.
Fuel system is a disaster but fixable.
Still have to check the IP.
Generator will stay mounted on trailer
Plan is to fabricate a solid exhaust extension or use the flexible Stainless exhaust pipe and come off the factory exhaust 90 degrees and exit the bottom of trailer.
A second muffler will not be used.
Pipe will be wrapped with Header Exhaust Wrap and the extra weight supported.
This should, I’m hoping, to quiet the noise a bit.
My question (finally) is this…….
With the extra length of pipe, will this create too much back pressure and cause the unit to run hotter than normal?
Should be no longer 4’ max.
My NF-2D generator route’s its exhaust this way and it’s really quiet.
I know Kubota liquid cooled and Onan Air cooled engines are two completely different animals.
Thanks
