G`Day again, my next job is to strip paint and service this control panel, I hate electrical work.

G`Day VP, I would leave the wrapping on the exhaust pipe. Doing so will increase the temperature in the pipe and reduce the tendency for soot deposits to form and clog the pipe.
I completely understand your horror at discovering that the insulation material is fiberglass, very nasty stuff to deal with using the correct protective equipment. Without it you would have been in a whole new world of discomfort. I hope that the itching and rash has gone away, I found that a very hot shower will remove most of it.
Not surprised that the supplier sold you a very large sheet of gasket material, probably been sat on his shelf for years. I have found smaller quantities for sale on Ebay but they are not cheap.
Keep up the good work.

G`Day again. Having fitted the brush holders and adjusted them, I decided I was on a roll so I refitted the transformer pack and pulled the wiring back into place. I then took a look at the radio suppression assembly and replaced the four buggered capacitors with new ones. The replacements are smaller than the originals but are rated the same, should be OK. Once these were fitted I powered up my multimeter and  checked the outputs between the neutral slip ring and three others. Just spinning the armature by hand produced 0.1 volt AC from each phase, very happy as it looks like there is enough residual magnetism left for this to re-energise itself without having to flash the field windings.

G`Day Guys and Girls, so having had two wet days I have been able to concentrate on the generator head. The armature is back in place and both bearing houses have been fitted. I popped out the bearing seals at each end and applied a little fresh grease before assembly.
I cleaned the four slip rings with a scourer pad and they look fine, no sign of wear. I spent a lot of time and effort cleaning the brush assemblies, they came out real nice. The brushes look good, one very small chip on one brush, I don`t think it will ever be a problem.

Hi Chris, Don`t worry about the skill level of the mechanic, looks like he is getting lots of on the job training.
The gunk in the bottom of the engine is probably the result of non detergent oil which allowed dirt and debris to sediment out. Modern detergent oils keep this stuff in suspension so that it can be removed by an oil filter.
Good luck with the cleaning.

G`Day Guys and Gals, not much to report, had to spend my day sowing grass seed as we have a wet weather event coming our way.
I did however, find the time yesterday to clean up and test the three phase transformer pack, everything tests OK, cleaned and varnished as per photos. This is a very simple set of transformers that regulates the generator output. All of the load on the generator runs through the 3 large transformer windings, this produces a voltage in the 3 windings on the other side of transformer which are rectified and fed to the field windings. As the load increases so does the voltage being fed to the field windings to compensate for the increased load. This should be a very stable generator so I doubt I will be worrying about an AVR.

Thank you, I have looked at some of the Indian offerings recently and have been very worried by some of the 10HP units running at 1000 RPM. Cast iron is good to 800/850 RPM, beyond that you need cast steel. I also have concerns about how well they balance these flywheels. I`ve also noticed that replacement crankshafts from India are a lot softer than the Lister originals. A weaker crankshaft and an unbalanced flywheel is a recipe for disaster at 1000 RPM. I guess health and safety is probably a low priority in rural India.
I`m pleased to hear that there where counter balance weights on the 18/1 crankshaft, without them I suspect it would walk out of its enclosure and disappear like a feral dog.
Most of the recent offerings have taper roller bearings, not entirely a bad thing as they can be adjusted to reduce end float by anyone who knows what they are doing. Trouble is not too many people do know what they are doing!
