New guy with Powerline 2-20
cjmac:
Hi,
I have been looking at a lot of posts on your site now for several months. I have learned lots. I thought it was time I posted something.
I have acquired a Powerline 2-20, in running condition, with a Marathon 4 pole generator head and all the associated parts for heat recovery from the water jackets and the exhaust. This system used an air starter (Gast 06) and ran on veggie oil after starting on diesel.
My plans for it are to be a fun toy to display running and an emergency power source. It is all dissembled for moving and it will be quite some time before it is back together. In the several months that I have had it (to think about), I have identified a few things I hope to improve on. Most relate to starting it. It currently takes way too much air to start. The air motor may be larger displacement than is necessary. It uses a rubber drive wheel held against one of the flywheels by a pneumatic cylinder, very similar to systems I have seen on this site. I am thinking of replacing the air motor with a 12 volt starter motor and either keeping the rubber drive or using an automotive flex plate and maybe modulating the starter voltage so it can accelerate the flywheels without breaking something. I also think about using the currently unused glow plugs and adding thermostats so it warms up properly (there was some soot).
Anyway, as time passes I will have lots of questions. Meanwhile, I though I would introduce myself and say a bit about my project.

Hi Chris, welcome. I`m looking forward to your project. If you are going for an electric start system I would recommend a 24 volt starter motor, I think you might be pushing it with a regular 12 volt starter motor unless you gear it down a lot.
Can`t wait to see what you put together.

Welcome Chris
There's loads of fun to be had with a Lister / iod!
Bob is right with gearing a 12v starter down, I did it by adding a standard Land Rover 2 1/4 litre diesel flywheel to the alternator, rather than the crankshaft, and mounting the starter motor on the bed.
It gives about a 2.5 to 1 reduction. There's more than enough grunt, it will throw the Lister over TDC even when the flywheel is wound forward to the compression stroke and the next time round it fires up and runs away.
in practice, when the fuel is cut and the motor winds to a stop it 'bounces 'of the final compression stroke and runs back a little giving the starter a chance to build up some momentum for the next start.
I don't think it would have any problem with a twin.
A useful side effect is that with the decompressor engaged it whips the engine around at a rate of knots that makes bleeding the injector a joy!
Cheers

Hi Chris,
Lots of help here and lots of knowledgeable people.
Just fire a question anytime.
And keep us posted as your project develops.
We like pictures :)

Thanks for the warm welcome.
I think I have the picture part figured out.
We took off the flywheels and other parts and dragged the engine on two 4'x6"with a come along. Then lifted it with an engine hoist and drove the tracked dumper underneath it.
Once I had it home, I spent a little time cleaning it up.
I just brushed on some enamel paint for added protection for now.
There was significant soot and grime on everything. As I cleaned things I painted and sprayed with rust preventative.
The preview button didn't show the pictures. I will post this anyway and see if they show up there.
