Lister Based Generators / Re: Lister Petter LPW4

Hi again Dieselgman. I have not given up on my HR4 either, lol. I would say that my new addition is the LPWS4, as it has glow plugs in the heads. The Deep Seas panel doesn't have any visuals for any engine or gen parameters, just idiot lights and alarms. I figure it would be easier and cheaper to add gauges and meters, rather than to rewire and buy an up to date control panel. Thanks, Derek.

Lister Based Generators / Lister Petter LPW4
« on: December 12, 2017, 12:14:17 AM »
Hello. I acquired another Lister Gen set. This one is a Lister Petter LPW4 or lPWS4. Not sure what the difference is and hard to find any info explaining it. Anyways, It has a Mecc Alte 16.1 KW, 4 pole at 1800 RPM alternator, 60 Hz, 120/240 Volt. Has 57 running hours on it, just like new, Gov surplus, taken out of service October 2017. It has a Deep Seas control panel. I would like to install a tach, voltmeter, oil pressure and water temp gauges. The control panel doesn't let one monitor any engine or gen parameters, but it does have the auto start function along with all the other shut down alarms and functions. Looking for some info or guidelines on installing electric gauges, what are the thread sizes on the existing senders on the engine block, oil and coolant? Any help would be greatly appreciated. I want to install volt, amp and frequency meters for the gen also, but that can wait for now. Thanks, Derek.

Hi Dieselgman, yea, I could make one on my lathe, but need a pattern or an old injector to do so. I am reluctant to start any kind of teardown until I have the tools necessary to do the tests. As Murphy's Law says, as soon as I start a tear down, then the power goes out, and I don't have a genny running. Yes, it is a 6 pole alternator. This unit was made to run 24/7/365, even though it was only ever used for a back up. Yea, if you have a test injector for the HR4, I would love to borrow it, or even buy it. If I had an old injector, I could retrofit it to connect to a pressure gauge. Thanks, Derek.

Hi Dieselgman. Where can I get a dummy injector for the HR4? I say it is a compression issue only because when I give the air intake a blast of hot air, she starts, but still hard. Diesels need either warm air or warm fuel to start, so I was told that many years ago. With that said, checking the compression, and removing the intake and exhaust manifolds to have a peek at the valves for coke buildup, would be a start. When I have the injectors out, I can check them and the spray pattern as well. I still need to find out where to get a dummy injector for testing first though. This HR4 and 18KW Kato are a tank, she only runs at 1200 rpm, 60 hz, weights over 3000 lbs. Thanks, Derek.

Hi all.  My Lister HR4 starts hard, exhaust is whiteish. Before tearing down, decoking, etc, I would like to pull the injectors and check the compression. I can't find any where what the compression readings should be. I am assuming 350 psi or better. I also assume one needs a dummy injector to do the test.  Thanks, Derek.
