The charge alternator bearings arrived yesterday so today I re-assembled the alternator - all went well until I realised that I'd left a spacer off - Plonker ! - didn't take too long to take it apart and put the spacer in, and now it spins beautifully on its new bearings. The rear cover was pretty knocked about so it got grit blasted and given a coat of zinc rich primer.
Having got that pesky grub screw out from the starter motor terminal block I wanted to replace it, but what thread? Almost 2 BA but bigger than 4 BA and not metric - what the heck is it? Turns out that it's 8-32 UNC that nice common size! However the gods were smiling on me as it turned out that I have a whole box of them - OK they are Hex socket ones but that's OK. So starter motor cover replaced and it's ready for a lick of paint before re-installing.
Today electrical parts have started arriving. I've sourced an old style Contactum metal single phase consumer unit. I've previously used an identical one with it's innards stripped out, to house 3 phase MCB's and an Isolator so I know that it will take Wylex 3 phase MCBs and I also have a Contactum 30 mA RCD on order so this box will take the low current 3 phase from the main alternator via the RCB and a 6 amp MCB to feed the front panel metering, so at least it is a bit safer than the previous unfused and non RCD'd arrangement.
Also the three new fan belts have arrived and seem to be correct I won't know for sure until the charge alternator is re-fitted.
I spent some time investigating the various sensors and switches on the engine. On the oil feed there is what I presume to be a simple pressure switch, it's open circuit - OK it may well close on pressure but if it doesn't it's a commodity item and easily changed. On the housing for the spigot for the water hose leading to the top of the radiator there is what may be either a temperature switch or possibly an analogue sender - I can't unscrew it yet as it's below the water line, but I will when I drain and fill with anti-freeze (memo to self - order some!). Then on the water / oil heat exchanger that is bolted to the engine there is a tubular heater element marked 220-250 Volt which is obviously a 'winter warmer' to aid starting, however it is currently open circuit. Its fixing flange nut measures 42.82 mm AF and try as I might I cannot get it unscrewed using large adjustables, and I don't want to ruin the rather thin flange. I may end up cutting a ring spanner on the plasma table, but of course until the engine is drained I can't completely remove it anyway.
The mounting plate for the fuel solenoid must have taken a knock at some time in it's life as it was bent rather Z shaped. I removed it, squashed it flat on the 60 ton press, grit blasted it and gave it a coat of zinc rich paint.
After that it was a case of more paint scraping to try and remove the flaking bits - I can see this could go on for days, but I have to be realistic and say enough is enough and hope the new paint glues down what I've missed
