    Default LPW2 Questions

    New to the forum been lurking looking up some info and have a few questions. I recently purchased an LPW2 outta a genset i donít know which. Came with the flywheel an all. Now my plan is to put this behind my Lincoln welder (9kw unit) Iíve researched and read these engine are 1800rpm all day long but can achieve 3600rpm which is where Iíll need it for the 1-3minutes thatís Iím actually welding. Is that true can they reach that rpm? Side note Iím a huge gear head and plan on heavily modifing this engine (turbo charger, intercooler, lift pump and bigger fuel lines)

    The MFG website shows they are rated for higher RPMs. Here on the forum the application is 1800 RPM so I don't know how much info we would be able to offer about what you are planning to do.

    I'd be really interested to hear back about your experience though!

    I’ll add updates. Thanks for the info. Worst comes the worst I’ll add a small pulley system to compensate for what I need. But yeah I got the engine rebuild, new rings and injectors. I actually married it the welder the other day. Almost ready for a test fire just have to finish, the plumbing for the turbo and fuel lines and thing like that. This is where I’m at now, just for an idea

    Thanks. Hope to have it done before spring. So I can get my side work going. Because I’m trying to keep it as compact as possible I hardly have the room for 1 battery let only 2, the engine is still 24v system are there 12v starters and alternators on the market for these engines? I did a quick search I’m thinking about picking a GM 1 wire alternator and swapping the pulley but will still need a starter

    I have seen these converted to 12v so they do make the pieces. I am not sure where to tell you to look to find them though

    You can definitely get 12V starters and alternators that are OEM and aftermarket ones as well. The easiest way to find one would be to look up your nearest Lister Petter dealer.
    I have a spare of both for my LPW3 that I have in Haiti. A lot of older civilian gensets from the UK were powered by Lister Petter LPW2-3-4.

    If you look in the L/P parts book, you will find the part number for the 12 starter.
