It appears on my end there is no "topics posted sense last visit" button anymore. Is it my end? Makes it hard to keep up on goings on!

Everything else / 3 phase from single phase
« on: February 23, 2018, 06:48:42 PM »
Is anybody out there converting on grid 220 volt single phase to 220 volt 3 phase? I'm needing to run a CNC 15hp 40 amps max. Not interested in building one just lookin for a good product that will give me stable 3 phase. The digital solid state ones seem to be priced up there. I also learned you need to upsize the converter about double to get good results. I have supplied a circuit with 100amps 220v to run whatever I go with. Rotary seems to be my $$$$ route. Looking for a been there done that reply that will keep me out of some of the potholes!

General Discussion / Charging a 6 volt off grid?
« on: April 20, 2016, 12:32:46 AM »
I have an off grid place with 12 volt solar + diesel generator. I also have a tractor there that has a 6 volt system and I want to keep the battery in a fresh ready for business state. Having the odd voltage around makes it hard to do this. A small solar system will do but finding a small but not to small panel is difficult. My question is would putting a 1.5 watt 12 volt panel cause the battery harm. I have a friend that does this with his and it seems to do fine. A suggestions appreciated!

General Discussion / Subaru EX21 charging coil / regulator rectifier
« on: January 29, 2013, 09:18:02 PM »
I know this is a little out in left field but I know there are some very knowledgeable guys on here when it come to electronics. Here is my problem....I picked up a Subaru Robin EX21 7hp gas engine. It already has the charging coil in place under the flywheel and it puts out 13volts at idle and 21volts at higher rpm. The engine comes with 3 charging systems. 15watt 40watt and 200watt. I doubt there is a 200watt hiding under the flywheel. The question I have is there a way to measure resistance of the coil and be able to tell which diode/rectifier (15w 40w) the charge system needs to properly charge a small motorcycle battery without pulling the flywheel? I have found the proper regulators but don't know what I have.
Thanks
Dave

Changfa Engines / Changfa Kubota radiator delete?
« on: April 22, 2012, 05:52:41 AM »
I have been putting together a small generator from parts I have acquired. The engine is a Kubota EA500-N.

I built a new frame and installed a Leece Neevel to charge batteries at our off grid ranch.

I thought I had all of the bugs worked out....oil leaks...bad seals but wouldn't you know it all of my test running a getting all just right before I was going to commit it to the wilderness and I have developed what appears to be a leak in the radiator. I am not sure if it is the radiator itself or the seal where it mounts to the engine block. I took it off and it appears someone else has also from the new silicone on the radiator where it mounted to the block. No soldiering has been done on radiator. I know many guys toss the radiator. I will do the same if this one is dead. Before I do that and all of the work involved I am looking for suggestions on how to check this style radiator. The coolant appeared to be coming from the tubes but in reality it was everywhere. It is well built. Any suggestions on how to find a bad tube?

Now if it can't be fixed what is the proper way to make a plate so an external radiator can be added?

Is it me or does this function not work anymore? I used this feature heavily to read what is going on but for some reason it has been saying no new post since last visit......do I have a rotten or mushy cookie?

Generators / Hz issue and what will 4000watts run?
« on: April 04, 2010, 08:33:58 PM »
I picked up a EA500-NB Kubota the other day. I have pretty much sorted out the oil puking breather issue and am in the process of replacing a leaky seal on the manual crank start shaft. It is a super good runner and of obvious better quality than the other imports.



So as I am becoming more confident of the engine I am planing on adding a 12 volt alternator to charge batteries at our offgrid ranch. My only requirement for 220 volts is a 1/2hp submersible well pump and occasional my wife's hair dryer. I put a Kill-a-watt on it and it says one side is near 60 Hertz and the other is around 40-45 Hertz. It will operate lights and heaters fine but I don't want to do in my pump! What might be the cause of this? If it will start my pump (the capacitors are topside) and run it I will look into fixing it. My 6/1 oid w/st-5 will run our 3/4hp pump here at the house with no problum so I'm assuming it should handle the 1/2hp no problem.  I want to keep the unit as light as possable and a new ST 5 or ST 7.5 will add much weight and size to the assembly.
Any thought will be appreciated! I have a picture of the faded label but there is nothing really there that is new. I know it is 1800rpm 60Hz 120v 220v here is a pic.



Thanks Dave

Listeroid Engines / XYZER hollow dipper failures?
« on: January 15, 2010, 05:02:20 AM »
Has anyone out there had a hollow dipper failure out there?? I have never had any negative feedback from anyone. There are maybe 75-100 out there. If anyone has had an issue jump in and let me know.

General Discussion / Offgrid Internet providers?
« on: July 31, 2009, 06:53:35 PM »
I'm not off grid but in the boonies! My choices are Hughes net satellite or Wild blue satellite. Dialup is a pain and I need some improvement. Is there any feed back out there on the 2 satellite choices?

Engines / Lister Identification help
« on: July 18, 2009, 01:15:04 PM »
I need some help in identifying a Lister. It is 500 miles away and the owner is 82 years old with no internet connection (experience). I might be able to get a picture if I call around and get someone to go look at it. Here is the information he gave me.

2 cylinder 1800rpm
Direct coupled to a 1800 rpm generator.
Model # 6215SR2A21
There is a #BS649 on the ID  plate.

He is searching for a manual to fix the problem it has. It will loose diesel into the crankcase while it is running.
Runs excellent but wants to fix the problem.
Any information will be appricated!
Thanks
Dave

Listeroid Engines / 2nd Fire...Breather slober....and why.
« on: May 17, 2009, 05:17:33 AM »
I did a tear down of my first 6/1 to correct a few issues like growling bearings in the ST and paint everything up nice. I didn't know how well the portable idea was going to work out and skipped the make it purdy part. The rod bearings looked good Timken’s everything looked fine. It always wanted to loose a bit of oil out the breather but nothing a rag wrapped around it couldn't handle. I always suspected oil running down between the precision sheet metal splash guard on the inside of the breather inspection cover was the culprit so I straighten it all up so it sealed good against the inside of the cover. I had the crank polished put in a new set of rod bearings a new gasket set and did a fuel filter upgrade. Then came the time for the 2nd fire.....got it all bled out...what a pain! Someone on here mentioned pressurized the fuel tank and that seemed to aid in the process. She fired right up and did great. I adjusted thing and tightened up this and that then noticed a good flow of oil coming from the breather. All those negative things came to mind! I didn't line the ring up right...or they were worn out...that will teach me to check the ring gap! But the way it was loosing oil just didn't make sense! If the rings were that shot it would not start and run so well. I have heard of others with this issue and the tied rag was mentioned, also blow by. Well I figured out what was the culprit in my case. If the precision sheet metal splash guard has to small of an opening the air on its way out picks up velocity taking oil with it. 3 hours might dump a quart.  I pulled off the inspection cover and took a screwdriver to it and bent it out so it had a big air passage. What do you know it no longer pukes out the breather.
