Well the weather this weekend was lousy, wet and cold. On Saturday I decided to pull the oil/water pump on the Hindenburg off and in the process dropped the oil, filter, pan, thermostat and coolant. I was happy that there was no engine killing sludge therein, and the oil pickup tube was nice and clean, but I pulled it anyway and cleaned it in my ultrasonic cleaner.

The oil/water pump assembly though, was externally filthy.

I went to disassemble the pump and the nut on the impeller shaft just snapped off, with the threaded portion of the shaft therein. Fcuk. Not that it made any difference, the shaft's mechanical water pump seal portion was rotten with rust, so bottom line is, I'll need to buy a new shaft assembly.

The mechanical seal was flogged out as well, so while I have a "rebuild kit" with new seals, I wasn't looking forwards to removing it because it's usually a b1tch to remove, but this time it almost fell out.

Oh well, it explained the oily muck all over the oil/water pump body, there's a weep hole at the bottom of the pump that will allow either oil or coolant to dribble out of under the pump depending on which seal (separate seals for oil and water sides) has failed. I couldn't go any further so I replaced the pan and installed a new K&N filter and I'll have to wait for the new shaft assembly to arrive before I can go any further. Oh well, I checked the thermostat in boiling water and it worked fine, and I'd bought another fairing panel to replace the toasty one, so I installed that.

I reinstalled the other fairing panels, and covered up the hole where the oil/water pump used to be, and put a bike cover back over it.
On Sunday, Spotty and I reinstalled his ram that he'd fixed for his bike lift, then wheeled on the white BMW that I blew up on Mother's Day, jacked it up, and did some more work on it. We'd spent enough time cleaning and painting the replacement engine, carefully installed the "new" engine (that's been sitting in a guy's garage for 20 years or so) and yesterday installed the exhaust and airbox/air fuel meter, EFI computer, and the fuel tank. We'd previously filled it with oil and coolant, so we decided to put some fuel in the tank and see if it would go. It did.
Can't be unhappy with that, the engine sounds good, but as it was still cold and wet outside Spotty's garage, and also because we haven't put the fairing lowers or seat back on it, we just called it good, and next weekend we should have it back together, and I can take it for a ride.
