Today I had to the 3000 hour overhaul on the ships auxiliary diesel generator. After 10 hours today, I pulled the injectors, cleaned them up, readjusted the popping pressure, and put them back in. Tomorrow I have to do the valve lash.
Anyway the engine is a Bergen (Rolls Royce) BRG-9, 4stroke, 5190 horse power, whose soul purpose in life is to turn a 3.5MW generator for auxiliary purposes meaning it hardly ever runs. In 10 years it has 2530hours on it. This was the first overhaul done on it so I was pretty excited to rip into her
something I wanted to do since I was put in charge of her over 2 years ago.
Anyway, so here's some pics for you guys.
Opened up the valve covers and inspection doors to get at the high pressure pump, supply and return lines, and isolate the air start.
A dirty injector
Actually this is not bad at all even though you can't see the pintle holes too well
Cleaned up, the injector itself is about the length of my harm minus my hand.
Tip. Readjusted the popping pressure to 5510psi. They were all off by about 1200psi
One of 9 high pressure pumps
Rockers
Injector back home. After seeing it out, this gives a good idea of the size of the rockers and valve spring. I can easily stand on the rockers and my shoe doesn't overhang at all
Push-rod housing
The coolest part was starting the engine manually. Usually I do it from the operating computer but actually bringing the engine to full rack and pressing the air start is a awesome feeling. At about 300rpm the governor takes over control and maintains 700rpm. On load she sips about 30gallons of fuel per hour. Hope you like the pics!
