Things I want to Buy / WTB Pulley for ST5 head
« on: August 11, 2015, 02:22:24 AM »
I have a 8.5" diameter Allmand drive 6 groove pulley with SK bushing. Its too big for my engine I would like a 7" to 7.5" 6-8 groove or..? . If you have one or can make one to order, or know someone who can let me know!

Listeroid Engines / 6/1 688rpm/60hz and erratic governor?
« on: August 01, 2015, 10:15:54 PM »

22.6 " diameter must be slightly smaller than most flywheels, and the math confirms it; I had to increase the rpm to around 680 to get 115volt/60hz on the ST-5. At this speed there is more vibration, and I am seeing peculiar readings on my tinytach, mostly I see 680-688, but 730, 800, and even 1020 even flashes as the reading updates. Should I be concerned about this? I don't really notice an obvious speed fluctuation observing/listening, well maybe for a split second when it flashes 900-1000, but if I didnt have a Tach I wouldnt have even noticed a speed change when adding/removing a load. Only when the engines loaded the tones deeper. Would this be a governor issue? One thing i had to do to unscrew the spring to get it to 680 is I had to take out the one small screw at the end of the threads, doing so allows it to wiggle more since there is only the adjustment screw holding it. I do have some play in the rack, and saw the spring fix and will try that soon. Also I am wondering how much vibration is from the ST5 only being held down by its own weight in the base track. I was thinking of making some brackets.

Ultimately I wish I could find a smaller pulley, I feel like it is just running too fast, 8" would bring it to 650 rpm which it ran more balanced. Actually 600rpm was my favorite highest speed. That would require a 7.5"

Listeroid Engines / 350 rpm 6/1?
« on: July 30, 2015, 11:31:41 PM »
I remember a while back there was a lot of talk about running the 6/1 at 350rpm. Im having trouble finding any of those threads. Just wondering if anyone reading this runs their engines this slow and what their experiences have been as far as governor control and proper oiling. I bought a 4.2 inch pulley for my St-5 just to try it out (although I checked my math after and realized I should have bought a 5"). I thought for a lot of my use Im just charging my house batteries and running a few small loads and running full speed just for that seemed overkill.

Listeroid Engines / Injector Pump Not Pumping
« on: July 20, 2015, 07:20:28 PM »
So after sitting a few years my Listeroid 6/1 Bosch Pump was all gummed up from straight biodiesel left in it. I soaked it overnight in Xylene and it freed it all right up and everything seemed to be moving freely. The first odd thing I noticed was if I screw the drain screw in the back all the way it stopped the rack from moving, so I figured a rubber washer must have been there and disintegrated so I added a rubber washer... Well I was going through all the steps to get air out and all went fine until I got to the last step where I connected the hard injector line. Turning the engine over nothing pumps, no fuel comes out. Now if I remove the top bolt and take out the spring and turn the engine, the small part in there pops up like normal and fuel wells up and overflows, but if i assemble it all then nothing pumps. So Im wondering what happened. Was there more rubber parts in there that disintegrated? It does seem now that the small part (I believe its the delivery valve) in the top that the spring sits on is looser now, it pops up and  comes out easy. I never noticed that happening before. Im wondering if that back screw isn't just a drain but it also holds something in place? Any information comments and advice welcome here.

Lister Based Generators / electric motor or direct drive?

I have a 6/1 with an st5 head.

 I would like to run some woodworking tools. 

Two ideas:

1. I was going to setup a 240volt circut, so I can make full use of the ST5s capacity without modifying it. What I wonder is: what is the largest HP motor can this setup handle; the main concern being the startup surge,( the load itself I sure would be fine). The one tool I have requires a 3-5 hp motor. If anyone out there has tested a motor of this size with a 6/1 st5 setup let me know.

2.I was also thinking of direct driving it off the listeroid, but I have yet to source out an apropriate hand clutch, so I can immediately stop the planer without having to stop the engine. If anyone has done this, or knows about an apropriate clutch let me know.
