Good Job! How about a new video of the engine in operation.

Mine never ran well with the COV set at the low compression setting. Kind of makes sense, as diesel engines run best with high compression.

$1000 for a 100 AMP 24 volt LFP ( or $2000 for 200 amps comparable to my current setup)

To replace my four 225 amp lead acid deep cycles, the total cost would be $800.

A huge price difference for 200 amp batteries.
 

I will have to look that price up, that seems too high. Just checked, LiFePO4 prismatic cells are still reasonably priced if you make your own battery bank. I'm seeing $108 ea for 280AH cells.

Even so, 100AH LiFePO4 is roughly equal to 200AH Pb-acid. As the depth of discharge limits on PB batteries is pretty severe.

This setup is really awesome. It takes the incredible capability of the Listeroid and couples it with modern technology. Really, the only thing it gives up is the simplicity of a belt drive generator head that directly powers a home. However I'm 100% convinced the benefits outweigh the downsides. I'd even bet overall system efficiency can be pretty darn good.

A combined heat and power setup like that could be incredible. And you can burn any kind of oil you want!

Very nice setup and thanks for the videos. It's one thing to understand what's being described. It's another to see a fantastic installation in all it's glory, and watch it function properly.

Take the cap off, and take some pictures!


Remember, the cap probably only goes on one way, so it might be a good idea to put a center-punch mark on the rod and cap to ensure correct assembly.

Oh that's a shame. Sometimes we feel like we know each other!

38ac, I figured you'd have a torque spec. In any case, thanks for the good information!!!!

I honestly do not recall using any shims on my engine. But that was 15 years ago.

The nuts must be tightened properly! The stress on connecting rod bolts is cyclic and they will eventually fail, "IF" not tightened to a certain level of stretch.

Put another way, once the bolt stretches and clamps the 2 pieces together, the bolt never feels any additional force, as the running loads are lower than the stretch force.

I took a picture of a spare (damaged during manufacture) Listeroid connecting rod I had at the airport. I tried to make it contain all the necessary information in one picture.

1) The 2 (two) lube holes on the top bearing shell
2) The "dipper" hole on the bottom that holds the bearings from rotating (where the drill bit is) And why you must be careful not to tighten the dipper against the crankshaft
3) Showing a 13/16th's wrench that fits the nuts
4) The lower bearing shell with just one hole
5) How the "nip" is measured, with a feeler gauge on the left side of this pic (remember the bearings must be installed)
6) I still have not found a torque value for the connecting rod bolts/nuts

And so on. Hope it helps. It's really simple, and the use of just a little care will give great results.
I have hope your crankshaft will be fine with some careful cleanup of old bearing material.

Again, if I go out to the airport, I'll take a few pics. That should help A LOT.

Just a quick note about the connecting rod cap "gap" (with just one bolt tight). Maybe this exists as a way to "tighten up" a bearing with a bit too much clearance. A really nice feature when you need a running engine now!

I'm not sure of the nut size at the moment. All of my lister spares are in storage at the airport. Maybe if I get out there I'll have a look. 

Found an old manual. The connecting rod nut is 1/2 Witworth. The bearing clearance should not exceed 0.003 inches. I did not see a listed torque. The manual I have simply states:

"This interference or 'nip' is measured by placing the bearing in the connecting rod, tightening both bolts to the normal extent, then slackening one bolt only and measuring the corresponding gap in the rod at the parting line. This gap should be between 0.004" and 0.006". All this does is keep a con-rod cap from crushing the bearings.

So, that's pretty simple, "if" the gap is 0.015" then simply install shims to bring the gap within spec. Tighten the nut and install cotter pin.

The nuts have cotter pins, so the torque is generally to a spec (which I don't have at the moment) then "to the next hole", then insert the cotter pin.

As always, a simple look at the bearing shells will show a lubrication hole that must be aligned. And don't install the "dipper" so tight that it rubs the crankshaft!

What an incredibly cool version of the CS engine.

I'm not sure what engine you have. Maybe you could post a picture of the engine and it's data plate.
