Thanks Broncodriver, progress is slow but steady, got nothing done yesterday because my Wife decided to rearrange our house. Spent the day moving furniture, with the help of a friend. Too old to be a furniture removalist, can hardly move today! 

Some progress made regardless of my being stiff as a board. Armature cleaned and now has 2 new coats of polyurethane, cooling fan has been etch primed and painted. Electrical continuity has been checked on the windings and everything looks OK.

The four field winding coils have been cleaned and rust removed. They are now re-installed in their casing and the cabling soldered back together with heat shrink to cover the joints.  This assembly has had a new coat of polyurethane and will receive a second coat in the morning. There is electrical continuity through the field windings.

I`ve started work on cleaning up the 3 phase transformers and bridge rectifier that feeds the field windings. The bridge rectifier is made up of 6 diodes bolted to two separate aluminium heatsinks. The diodes all test OK. In the morning I will check the electrical continuity of the transformer windings.

Few pics attached.

G `Day People. Not much progress today but I did manage to clean the mating faces and fit the fuel injection pumps and fuel control solenoid. Pics attached.

G`Day folks, I`m still waiting for bits to be delivered so I can`t move forward with the Petter PJ2.
So, today I decided to strip the 3 phase generator head. This head has four slip rings and is wired as a Y with 3 single phase 240 volt supplies on each branch of the y, rated at around 20 Amps for each leg. Alternatively I can draw 3 phase power at 415 volts off the three outer legs. Early inspection shows no wear in the bearings or on the slip rings/carbon brushes. This tool has sat in a farmers field for the last ten years, so there is a lot of rust and detritus so it will be cleaned and repainted. the field coils will be cleaned and soaked in polyurethane varnish as will the transformer assembly that feeds the field coils.
A few pics showing dismantled components.

G`Day, the wiring for the engine side of things is completed and looks OK, not the right time of year for this type of work, too cold to be sitting on a milk crate for many hours.

G`Day folks. Not much to report today, I`ve started building the beast a new wiring loom.  The old one was badly made and all the insulation had perished and cracked.This is going to be a bit of a mission because this unit has every imaginable sensor and all wired up to a fuel control solenoid to shut it down if it gets too hot, oil pressure drops and etc.
Just a couple of pics.

Thanks for the heads up Bruce. I`m currently working on getting backup power generation for my home and shed, this will include my old CS 6/1. I will definitely be investing in some split collars after your experience.
When I was doing maintenance work in a large sawmill we had a lot of equipment with gib keys. These would work themselves loose at this time of year due to the temperature changes at night. 40 degrees during the day and down to zero at night.
Very glad all that work you put into electronic monitoring paid off, I can`t begin to imagine how much damage a flying CS flywheel would cause at 650 RPM.

G`Day folks. not much progress today because it is Anzac Day. equivalent to Remembrance day in the UK and Veterans day in the US. Time to lay down the tools and remember that the freedoms we enjoy were bought with the lives of a great many brave young people from all over the world.
I did manage to fit the new oil filter and its assembly. I am encouraged to find that the filter I took out had a 1978 date stamped on it suggesting that this unit, made in 1976, has had a least one service in it`s life. I am very disappointed by the quality of replacement oil filters. compare the 1978 unit with the sh1t replacement made in China or India! I`m sure it will work but what a drop in quality over the last 40+ years, so much for Globalisation!
I also finished up fitting the oil feed lines. A few pics attached.
