can anybody help us identify the proper letter designation of this engine so when we have to order parts we get the correct stuff.
thanks

That is the data plate for the engine. How useful it is might be a different item. What parts are you ordering?

There's ordering MEP-803A parts, there are Onan specific parts, there are Lister Petter (LPW4) model parts, and of course generic parts. The most specific is always going to be MEP-803A parts, but more general parts may match, e.g., Lister made a variety of engine versions, but bear in mind that not all versions share the same components, so some care is warranted.

All the best,

You have a Lister LPW4 in an MEP 803A that was made for Onan & they name it the DN4. Don't use the China copy parts, it is not worth it.

thanks for the help

Not sure if everything comes up when searching the US Ebay site, but in the past I found a lot of OEM engine parts on the UK Ebay site.
You can also get some parts direct from Cummins' on-line site.
Also if you suspect a problem with the Cam shaft, I have a couple used ones with the gear attached in my parts stash.
As well as pushrods and rocker arms etc.
If you end up pulling the head off you could set the engine at TDC and see where the lifters are at ( both valves closed ) then you can better watch the cam location and lifter as you rotate the motor.
Looking at the Cam picture it looks like the gear is pressed on ( and may have slipped ?)
I was thinking it locked into that slot on the end, but that is the governor apparently. ( I haven't been that far into an LPW4 in several years )
