We recently posted about attending the Northern Lights training class taught by Lugger Bob. Of course, after the class, the first thing we do is come home to Red Rover and look at our Luggers and our NLs equipment… And see that our 20kw genset is in need of some maintenance! We’ve put 490 hours on the generator over the 2.5+ years of ownership. Our survey at purchase only found a weeping raw water pump, which was replaced in the fall of 2016. What parts we did not have on hand were ordered and readied to be installed.
Here is the list of items that were replaced or completed:
- Raw water pump
- Coolant pump
- Coolant hose (removed hose appears ok, kept as spare)
- Exhaust elbow
- adjusted valve clearances
- Belt (removed belt appears ok, kept as spare
- Coolant temperature sensor
- Replaced secondary fuel filter
- Replaced the old clear coolant overflow hoses to black rubber hoses
- Replaced coolant
- Added a Start/Stop switch to the generator sound shield
Most of the images below show the telltale signs that caught our eye. After learning what to look for, the issues were quite obvious!
