PM Servicing Panda 4200 Generator

I have had this to do for a couple of weeks now. I'm always behind, I think I live playing Catch-Up. Anyway this Panda PMS4200 Genset is in a 33ft Pursuit. Well down in the Bilge area, very close quarters for a shorter guy but at 6'3" tall it is really a issue to do this kind of work for me anymore. The Genset is a 2008, we didn't get a maintenance record with the boat at the time of purchase. I did the Survey work & negotiated the deal for my friends when they bought it. Now with summertime on the horizon my bud wanted to know the unit was ready for use. Since I fixed his whole home genset after the installer told him to buy a new one I was ask to PM & service the Panda Genset.

This is a diesel genset, totally enclosed in a sound deadening fiberglass box, bolted 1/2 way under the Aft Deck, I had to remove the Exhaust hose, unbolt from the bilge base, lift the genset up and swing it out in the open because the Water Pump is on the backside bottom of the unit.

The Genset is down in this hole.

The Cog belt was replaced. It drives the water pump. I bought OEM parts for this service.

The Water Pump Impeller is behind that plate. For perspective on the nut size of the fasteners holding the Pump Plate on they are 4mm X .07 Pitch. Super tiny, a 7mm socket and some butyl tape was used to stick the nuts on the end of a phillips #2 screwdriver to hold the nut in place so I could start it with a wrench. Only enough room for about 1/8th of a turn. In the front bottom I used the socket, universal, extension taped together setup. Some butyl inside the socket held the nut till I could thread it on the stud. Glycerin is used to lubricate the Impeller & O-Ring on reinstallation. I still have to change the oil. Just another day in Paradise.
