Hi everyone!  I'm Tom, I've just joined you on here as i've bought myself a Lister HA3 air cooled engine as it was only going to go to the scrap bin which horrified me!!
Unfortunately it hasn't run for a few years and is seized so needs a strip down and rebuild. I know a little bit about engines but not much about Listers. So, I need a manual and preferably a assembly diagram with all the parts on it.

The engine was mounted to a railway 'Grampus wagon' and attached to a 3.5ton winch which I've also acquired. Any knowledge and wisdom will be greatly appreciated.  thanks!
Tom
