This Onan 30OEK propane-powered generator has been in service for 39 years at a transmitter site where the power goes out often. It has a lot of hours on it. The hour meter stopped working about 15 years ago, but the hours back then were 1097.<\/p>\n\n\n\n

In addition, the main shaft seal started leaking oil about 10 years ago, creating an oily blowback mess every time the generator ran for more than a few hours. The block heater went bad, the battery charger overcharged then exploded the battery splashing sulfuric acid all over the housing and engine block.<\/p>\n\n\n\n

The last power outage was the final one. It ran for a few hours then faulted. When the local engineer tried to restart it, it was never able to get to speed and was misfiring badly. Below appeared a large and spreading puddle of engine oil.<\/p>\n\n\n\n

As this station is one of the major money makers for the owner, a replacement generator was obtained.<\/p>\n\n\n\n

This is larger than the old generator. The good news; now the AC can be put on the generator to keep the room cool. In the past, the backup cooling fan was used when on generator power, which sucked dirt, bugs, and pollen into the room.<\/p>\n\n\n\n

It will also have considerable headroom for any additional loads that may be installed in the future.<\/p>\n\n\n\n

We had to enlarge the opening for the radiator and put in some steel angle for the lintels.<\/p>\n\n\n\n

The first start run and load test went well. I ran it for about 30 minutes under full load, enough time to burn the paint off the exhaust manifold. Seems like a pretty solid unit. With the power conditions at this site, it will get a lot of use.<\/p>\n","protected":false},"excerpt":{"rendered":"
