Saved for further additions

Sticky Time :grin:

I would also suggest that you help support Steel Soldiers and become a member here.

What all do you get for upgraded membership? Increased PM box, access to the members only sections. Also we're looking to expand membership incentives, those are still in the works and will be announced later. (Looking at insurance companies, MVPA, and other things) Also, they'll be a new forum added in the members section related to firearms.

If you simply wish to toss a few bucks in to help us move to a better host, donations are accepted via paypal at: cstansbury@steelsoldiers.com

Thanks again for all of you who make this place great!

Does it make sense to publish all this info in a PDF and attach it to the thread containing the TMs?

You know what I would say. Do it. All this info is needed on a daily basis. Maybe not you old timers, but the new Guys. And the simpler you make it for the new guy to find, the easyer it is to help them. AND, perhaps you can develop the the habit of people looking first, and asking second. There is only one dumb question. That's the question not asked. But some people will always ask first, because they don't feel like they have the time to look. Or are too lazy. If we have such a sticky, it tends to cut down on such people. The people who want to learn will love you for the sticky.

Hello, I've been doing a bit of engine repairs on a bunch of these gens I bought and found a couple very cheap sources for full gasket kits ( $90 for 4 cyl.) , head gaskets, rings, bearings and such.
If you want to add to this thread I can send along some info.... The key seems to be to search ebay for Lister Petter LPW because most of what I found does not mention MEP-80XA or Onan DN*M in the description.

Howdy,

Original engine design = Lister-Petter
Authorized design = Onan
LPW2LPW4
DN2MDN4M

All the internals are the same. Pistons, rings, water pump, oil filters, injectors, valves, rockers, etc.. The difference is 1 being 2 cylinders and 1 being 4 cylinders.

I am not sure why this isn’t a sticky. I used it again this week.

Thanks for putting this together for everyone.
