So the next thing to do was to see if she would crank over and hopefully shift a bit of oil about before actually letting her fire up. So I firstly removed all the existing wiring from the fuel solenoid and the starter solenoid, and jury rigged a wire to the starter solenoid, having wired in the new pair of batteries that came yesterday.

Dabbed the starter solenoid wire to + 24 volts and zilch, nowt, nothing  :bang:

Removed the cover from the back of the starter motor that includes the solenoid, measured the coil at 6.7 ohms which seemed reasonable, worked it by hand a few times and tried again. She turned over smoothly and easily with no horrid noises but no oil pressure at cranking speed.

OK in for a penny, in for a pound ! I wired the fuel solenoid to a switch, proved it operated AND released (want to be able to stop!) and then went for a 'first start'

She started very quickly, produced a small puff of black smoke then the exhaust quickly cleared -

SHE RUNS !
The alternator output is isolated and at the terminals she was producing spot on 415 volts phase to phase, but this is unloaded of course.

So she is basically a runner and now needs loads of cleaning up, pulling all the old wiring off, and wiring using the new Deep Sea controller. But now at least I know I've not bought a complete lemon !

Whenever I have to find the balance point of something like that I lift one end then roll a pipe roller under it. Move the pipe along until it teeters when I let it down and mark the pipe location with a paint mark.

Let me know if you need any control gear Andrew. I have panel switches, 24v supplies, relays, timer relays and a selection of contactors.

John Rudd:
Great build up to a successful run...

Now let's see it produce lectrick..... :zap:   :D

awemawson:
Many thanks for the offer Pete  :thumbup:

So where to start? Well first I needed to clean off the accumulation of vegetation that had settled on the rocker covers over the years. Initially I tried the workshop air hose and a hand brush but was getting nowhere fast, and what I did get off of course was on the floor in the Tractor Shed. Better to move it outside and bring up the big guns in the form of my diesel 'road compressor'

Worked a treat and had the advantage of blowing off some of the flaking blue paint that is going to have to come off anyway before it gets a new coat.

Ran it up again when returned to the tractor shed, and the only issue that I had was a slight oil leak from the nylon oil pipes that I presume directly feed the rockers. Self inflicted I suspect when I balanced the silencer up there for transport. Nipped up the fitting and we'll see next time it runs if it's cured !

I did wonder what your next project was going to be!

I recognise that type of starter. I've not seen one for a long time though. They do have a proper name, but I can't remember what!
I want to say coaxial, but that doesn't look like it's got a sliding armature. You get a version with a sliding coaxial type drive gear, but the name escapes me.

They were used for big engines with big starting loads. The last one I seen was from a big 80s combine, and the only place I've seen a coaxial was on a hydrostatic forklift that took a lot of winding up even thought it only had a 3 cylinder perkins!
