i've got a lister st2 diesel genset that's been sittin around waiting for some tlc. i started tearing the engine apart because it was all sooty and greasy. the manual calls for pain. rear seal is leaking(accordig to manual) so i removed the xhaust man/intake man, and the air duct. broken xhaust man on both cyls. sooty and greasy beyond imagination, although one cyl wasn't so bad. someone put in the center duct backwards. hmm. anyway the injectors were loose, too. apparently the soot and grease that wasn't on the engine, was drawn into the generator, and covers everything that doesn't touch something that spins. how do i clean this mess up without destroying the varnish/insulation wiring, agghhh. help. i got a great deal, and have worked on other engines, but this project needs knoweldgeable advise. sooooo! here i am, seeking your assistance. for your info, the generator is a Newage Stamford 3ph, 9 KVA, type D8C, cont rating, pf 0.8, 60hz, 220/127volts, 23.6 amps. exciter is 75v@2.45amps. any and all direction is appreciated.
