Listeroid Engines / adding a fuel lift pump
« on: September 26, 2018, 11:07:10 AM »
 I want to convert my DES 8-1  homemade generator to run off the 100 gallon bulk tank that sits on the other side of the wall on the ground (lower than the engine).  This will allow me to eliminate the fuel tank I have inside the generator shed.  The problem is I will need a fuel lift pump. the first thing that comes to mind is the little 12v pulse pumps I have used on stuff for years, the problem is I don't have 12v on my generator shed nor do I want to add a battery and charging stuff. I couldn't find any of them in a 120V rating so I gave up on that. then I thought what about  the cheesy little diaphragm pumps kohler and briggs use on their engines that pulse off the crank case. I could drill  a hole in the cover and screw it on and It should pulse.  Wondering if you guys had any other ideas.

General Discussion / botched crank grind.... too much rod clearnce.
« on: January 02, 2018, 12:26:26 AM »
how much is too much clearance on a rod? I picked up a B6000 Kubota basket case last summer. It has a little 13HP 2 cyl water cooled diesel (ZL600).
 It looks pretty over engineerd for the power it puts out. I had a bitch of a time finding parts for it but  finally got them from Greece. the crank was way off, out of round and under sized. I took it to a local engine shop along with the undersize bearings mounted in the rods and he sat on it for a month. finally I went to repo it and come to find out he botched it a bit. the one rod came out to .001 clearance but the other is at .007      I figured hey what can you do so the last few days I froze my but off out in the shop putting it all together.  got it running and seems to wok fine plowed snow with it in the driveway for about an hour today. I wonder how long will it last like this........

Lister Market Place (things for Sale) / LR1 in PA
« on: June 01, 2017, 03:46:35 PM »
lister LR1 4hp 1800rpm diesel engine. this was sort of a winter project, i put several new gaskets and seals on it. new brushes in the electric starter. built the skid you see and painted the whole thing. I was going to mount an ST generator head on it but am considering selling it to fund other projects if any body is interested. otherwise I will just keep it as a backup to my backups backup. thanks. located in north west Pennsylvania.

Lister Based Generators / induction motor as generator fail
« on: April 05, 2017, 11:39:57 PM »
I have heard the urban legend of an induction motor as generator for years, I have a little pamphlet from lindseys bookstore entitled "alternator secrets" I bought in the 90's. I also used info from this link well I set up a nice 3 phase 5hp 1725rpm motor coupled to the little 4hp lister LR1 I bought over the winter. made a nice base and used the doghouse from my ST head that I removed. wired it up in Star and it did nothing. waited for caps to come in the mail and added (3) 25uF caps in delta on the 3 legs and still nothing. Flashed the field and nothing. I wanted to use Star with the center connection as the neutral.  Just for kicks I rewired the motor in delta and hooked up the caps. started it up and the light on the doghouse lit right up. I thought that was cool so without a second thought I throttled her up to 1800 rpm and boom boom out go the lights followed by one of the caps being on fire. shut it down and  then in put the 20uf caps I bought as backups on and tried again. this time just idling It maks about 150 volts and if you give it any rpms the voltage goes way over the scale of the meter.  what is the deal? you supposed to add load and caps a little at a time as you load the motor as a generator? any body got experience with this? pics to follow if anybody is interested.

General Discussion / his vs her diary

Her Diary:

 Tonight, I thought my husband was acting weird. We had made plans to meet at a nice restaurant for dinner. I was shopping with my friends all day long, so I thought he was upset at the fact that I was a bit late, but he made no comment on it. Conversation wasn't flowing, so I suggested that we go somewhere quiet so we could talk. He agreed, but he didn't say much. I asked him what was wrong; He said, 'Nothing.' I asked him if it was my fault that he was upset. He said he wasn't upset, that it had nothing to do with me, and not to worry about it. On the way home, I told him that I loved him. He smiled slightly, and kept driving. I can't explain his behavior I don't know why he didn't say, 'I love you, too.' When we got home, I felt as if I had lost him completely, as if he wanted nothing to do with me anymore. He just sat there quietly, and watched TV. He continued to seem distant and absent. Finally, with silence all around us, I decided to go to bed.

 About 15 minutes later, he came to bed. But I still felt that he was distracted, and his thoughts were somewhere else. He fell asleep - I cried. I don't know what to do. I'm almost sure that his thoughts are with someone else. My life is a disaster.

 His Diary:

Lister won't start, can't figure out why.

for years we used my hobart champion 10kw welder/generator as a backup generator for when the power was out. we pretty much just run the whole house and show no mercy. usually i try to turn off the electric hot water heater and the pool pump but it has been known to run them both when i was at work.... this last summer the power was out for almost a week and the thing was killing me on fuel so i decided to build a lister cs generator over the winter. Got this built this winter and ran it a bit, I am very pleased with the power of the engine. i have been able to run the whole house and it only drops by about 1 hz. it seems to have plenty of power to spare. I may even change pulleys and lower it down to 650 rpm and see if it can haul the mail as good as it does now. any way it seemed like the lights on the computer power strip were flickering. then a day or 2 after a test run my well pump shit the bed. (it could be by chance as it was over 10 years old). sort of made us question the waveform of the ST head and wonder if it could be improved upon. So i bought a cheap o-scope off ebay from china and a 10x attenuation probe. took a round of readings, then added two 1000 uf DC capacitors to the DC going into the field. I thought maybe that would smooth out the waveform some.  I feel like you can see the capacitors effect on the Z winding and on the rectifier output but they ultimately seem to have no effect on the actual generator output. they don't seem to hurt and maybe they would help with starting the well pump. looking for insight as to weather or not this will help or hurt. here are my scope pics. it was fun anyway and the DSO138 oscilloscope was  well worth the 30$ i have into it, i would buy another one in a hearbeat.

Original Lister Cs Engines / advice on ST1
« on: October 17, 2016, 03:28:50 AM »
perusing the local classifieds and I spy an ad for a 4hp diesel. pics available on request,  I emailed and he sent some super bad grainy cell phone pics of an engine that looks like an ST1 lister. sitting in the dirt  under the edge of a shed.  I say this because I can see a spin on oil filter under and the governor spring on the side. he says it runs. going to look at it on wed eve. wondering what kind of money I should be willing to pay to pick it us as a spare engine for well.... I don't know. just because I want it what more reason do I need. and also what should I look out for. never seen one in real life before. I identified it from google pics. thanks. gus.

Listeroid Engines / DES 8/1 generator build
« on: October 10, 2016, 07:17:01 PM »
I am in the beginning stages of putting a new DES 8/1 and 10kw st head together in my greenhouse as backup power. I just got the stuff in the mail last week.  I thought I would try to post some pics here for you to look and enjoy as I build it over the winter.  I started tearing the engine down last night. I  got the flywheels off and everything but the crank out.  The  sump looks filthy like some real bad used oil was run in it during the test run but for the most part it is going good? I saw no oil groove inside the timing idler gear, I guess I am used to seeing that in a gear like that, wondering  if I should  cut one? I also noted 2 shims on 1 side of the rod bearing cap but just 1 shim on the other side. not sure what's up with that.  I have a needle descaler and plan on trying to get all the paint out of the inside of the frame but how else do you clean the frame ? do you just lower it into lye and water and let it soak? thanks gus.

Lister Based Generators / ST AVR upgrade
« on: September 30, 2016, 06:42:40 PM »
Hello to all, new to the fourm and lister's as a whole. I have been bit by the lister bug and am in the process of building a backup generator. I have ordered an 8/1 clone engine from diesel electric services and already had bought a 10kw st gen head off ebay. the st head appears to have no avr at all. just a dimmer that I can vary the field voltage with. I can't imagine that we would be satisfied with having to go out to the power house and adjust the voltage every time mama turns off the tap and the well pump kicks on and of so how hard is it to add an avr? I am tempted to buy one off ebay but now quite sure how many amps of field current it will pull or what avr to buy.  cunntly looking at these ones.
