The air ducting in Lister/Petter sound enclosures simply provide a serpentine path for the cooling air to flow through, along with foam dampening on all surfaces. This keeps noise dampened as well while providing an open air pathway.

Where is your temp sensor mounted? If in airstream - I would expect to see under 200 degrees F. Exhaust Ports may run up to 375 or so, cylinder head temp around 300 or under... mostly educated guesses for this engine. Book specs available if needed - gsj@gci.net

Tag stamping seems erroneous... Please post overall engine picture. We know all Lister types and can help identify.

Engines / Re: LPW2 Build 902 change fixed to variable speed
« on: January 21, 2022, 07:58:54 PM »
India sourced parts with the L/P packaging - standard procedure now.

On your LPW2, plenty of resources remain in Kansas. These were USA built for the USArmy and USAF MEP802 generating sets (and other applications). Most of these were contracted through Cummins/Onan and bear their Onan nameplates and valve cover castings. ALL built in Olathe Kansas. Diesel Electric continues to supply these parts resources, and continues to rebuild these engines. Governors differ between military and civilian types. Contact me if you need to equip yours.

Engines / Re: Paint Removal LPW

Heated sodium hydroxide (180 degrees F) in water is best for stripping cast iron hot-tank style. Not recommended for aluminum alloy, but there are also buffered versions on the market for that application as well.
We often leave the original red primer in place after all other paint and contamination has been released and rinsed from parts.

Engines / Re: Lister SL2 governor?
« on: January 21, 2022, 07:47:23 PM »
Does your unit have the correct governor weights installed? Many variations exist... fixed 1500 or 1800 rpm weights will be the heavier ones and usually equipped with 2 governor springs.

Engines / Re: Lister ST2 find,removing the camshaft?
« on: January 21, 2022, 07:43:20 PM »
ST2 Lister camshaft is retained by thrust bushings at front gear cover and engine block. Remove gear cover and you will see the cam gear. Remove governor assembly, withdraw fuel pumps and tappets, remove oil pump (out of bottom of block), remove pushrods and withdraw their tappets to top of bores... (best done with engine block laid on side). Cam will withdraw out front of engine. Check if fuel lift pump tappet is installed - remove if it is there.

Diesel Electric in Lyons KS is the best supplier for all things Lister/Petter. Largest inventory on the continent for certain... includes all legacy L/P products plus their more modern product lines. 100s of engines and multi-million $$ parts inventories.

gsj@gci.net is best contact.

Listeroid Engines / Re: Group order from India

We have a 15 year relationship with an India exporter who does our sourcing and other shipping and handling tasks in India. We bring in full containers of the various Lister clones as "parts kits". These are stocked in Kansas USA along with copious amounts of spare parts. The import costs have soared since we started doing this line of business, but can still be a good bargain because we do it in quantity. gsj@gci.net - diesel-electric.us

450 psi would be considered fairly "normal" although this is not a spec nor a procedure proferred by Lister for these machines. We sometimes get down to this if we have a balking engine that we cannot get an accurate diagnosis from the usual crankcase vacuum measurement. (i.e. the engine just cannot be started). What you are actually looking for is consistent even compression across all cylinders. 350 psi may be considered enough on one of these very small engines. You cannot test through an injector. Use an adapter made for the purpose.

Injectors should be bench tested for pop pressure, spray pattern, seal and consistency across cylinders. They can be installed inverted onto your engine if you want to confirm fuel pump operation as well, just cannot see as many details when doing it that way.

The leak-off line from top of injector allows the system to be somewhat self-purging of air in the lines. With a new tight perfect injector there may be no fuel bypass at all... with others there may be considerable, but that generally means that there is internal leakage within the injector body. Some CS models actually used a small open container to catch the very slight drip from the injector leak-off. Newer fuel systems route this back into the fuel supply tank or back into the secondary fuel filter as in your SR.

Have you tried using the cold-start cups?  Located on top of each intake runner is a plastic cup and plunger. These are designed to boost compression and top lubrication for initial startup - especially when cold. These can help make up for some minor compression loss due to engine wear in cylinders and rings. If the engine is internally clean, then a quick check on valve adjustment is advised.

If your fuel injection tests good, then compression is the next item on the list to confirm. These will not go out of time as far as your pumps are concerned unless someone has tinkered around and changed the shim packs. Knowledge of the machine history will always help in this determination.

Marine SR2 as far as I can see. We don't often see the old SRs in clockwise rotation in North America. The raised starter motor is an odd modification, first one I have seen done like that.

Generators / Re: I'm ready to buy a gen head..............
« on: March 31, 2021, 05:07:06 AM »
Stamford original or Chinese Stamford copy - very close to the same thing. Stamford original 8.2kW about double the cost of the Chinese clone. Lister/Petter  had Chinese manufacturers building most of their (rebranded) generator heads for the past decade. We stock a wide array of these machines.

There is no real penalty in running an 8kW head at 1/2 its rated output... so that is a non-issue.

That connection back to filter only serves to help bleed off air in the event of fuel tank run completely empty and a bunch of air getting into filter. It can be helpful at times, but not necessary.

Talk to 38AC - Butch. He has done this same work for us in the past - with excellent results.
