John Rudd:
Is it possible to be toooooo envious of someone? :)
I do miss working.....we had 3 3.6mw turbine gensets with deutz diesel hydro starters........
awemawson:
John, I don't miss work at all, but I do intend to enjoy my play time :clap:
Today's Progress:
I decided certain things needed removing as they would be far easier to clean up off the engine and actually will get in the way when it comes to spraying. So I removed the Purolator air filter housings, the instrument panel, all the contents of the relay box (fuel solenoid and starter relays) and also the top of the terminal box for the main alternator - this later item wasn't in anythings way but was difficult to clean being under the diesel tank.
I tested the ammeter and the oil pressure switch which both worked OK :thumbup:
Then I went into an intensive cabinet blaster blasting session, emerging over two hours later with some cleaned up parts ready for their zinc primer.
Prior to this I made a new window for the cabinet blaster - surprising how a gradual blast etching creeps up on you and you think it's misting - what a difference, I can actually see what I'm blasting !
John Rudd:
Looking good so far... :thumbup:
I guess by the time you have finished, it'll be worth twice what you paid for it..... :beer:
awemawson:
Well John, at least hopefully I'd be able to offer to demonstrate it working were I to put it up for sale, but that's not the intention. As you know I bought it as 'spares or repairs' as a bit of a pig in a poke, as I'd not even seen it in the flesh - sometimes you just have to take the risk and this time it paid off :thumbup:

After supper I removed the metering panel from the main 'box' reasoning that it is easier to remove it than mask it up for spraying. Anyway I need to sort out it's wiring. Essentially it is driven by the three phases and neutral for voltage selection and the hours meter, and the leads from three current transformers for the amps meter, so theoretically it shouldn't be too bad, but those stacked selector switches always confuse me as to what is connected to what and when :scratch:
The drive cables had to be cut to remove the relay logic board, but anyway the three phases and neutral need feeding through the 30 mA RCD for a bit more safety. The RCD arrived in the post this morning so I can press on and build the sub board.
The panels were retained by self tapping screws - I don't like self tapping screws in this situation, anyway they were quite rusty. I'll probably replace them with nuts and bolts as hand access to the rear is fairly good. I contemplated putting in 'hank bushes' and may still. At least there is no marking out to do, all the 'pilot holes' being there already !
