Some people are a waste of oxygen, the kid who received the Lister after installing the new connecting rod shells decided to turn the engine over on the starter then release the compression levers.

Since he was waiting on the fuel pump push rod had not added any oil in the engine, there was enough fuel in the lines and filter. Guess what, the engine fired up and the kid was clueless how to shut it down.

The engine seized before running out of fuel.

No, that is so sad.  The idiot should be keelhauled and if he survives, be forced to rebuild under supervision, at his cost.

I'm loosing track?
I thought you donated the Kohler to the young bloke?

Don't be too hard on him. He was probably just excited and inquisitive and didn't think things through.
If I had 10 Bux for all the stupid things I have done that I should have known better, I'd both be a rich man and have a hell of a lot less regrets and anxiety!  :0)

He'll probably be kicking and hating himself over it anyway.
The idea of helping him rebuild it at his cost is a good one.  It would probably teach him so much and turn one of his life long regrets into something he can look back on with some contentment instead of shame.

I have had a few things like that and I am eternally grateful and appreciative of those that helped me.

Taylor is not a friend, just a neighbor of whom I was aware is living off grid. i gifted the generator to him then when it left my yard became history.

He's in his mid thirty's by my standards still a kid.

I sense some hostility here.  Glort is obviously a far better person than I (and probably loads more sensible), as I would be livid with the guy and certainly would let him know

Vehicle safety inspections are required in this province which i have no issue with, I have a copy of the inspection manual and go over any new junker we purchase making the necessary repairs before taking the vehicle to the shop for it's pedigree.

The safety sheet the from the motor vehicle inspection branch has multiple choices, brake linings and drums require the measurements be written in.

Taylor did the safety on an 06 Dodge Ram and came up an estimate for $3,000.00 in repairs, once the paper work for the safety is done you either junk the vehicle or do the repairs but there;s nothing to say you can not take it to another shop. Which is what i did with the request they save me the parts removed.

The parts he declared faulty was all steering geometry and his hop does not have an alignment rack, the shop that did the work has a rack in addition I requested moog replacement parts.

Later on I had learned that I could have challenged the inspection, the MV would have sent out an inspector to double check  the inspection.

Any how after that lesson it is easier to deal with the shop that did the final work, now here's the clincher.

When Taylor came to pcik up the generator he flat out said that there would be no favors at the shop, I said no problem as you may have noticed I no longer have been using your services.

All he had to do was pick up free generator, a brand new set of connecting rod bearings and 4 new injector nozzles and go home.

Instead he had to beak off thinking the generator was somehow a bribe or that he would be otherwise obligated.

Gift and Free by no means implies any obligation.

Copy of the first email had sent Taylor.

Taylor if your interested I'm going to gift you the Kohler 8.5 Kw diesel generator, it has the Lister SR2 diesel engine, comes with a new set of connecting rod bearings. Did not really need  them, one con rod cap was removed for inspection but to damn cold at the time to install the new bearing.

Output is 8.5KW 120/240 volts, the gen head is the starter.

If your interested I'll move the generator towards the front of the shop for loading, I have an overhead rail and chain falls for lifting.

It's free, don't need two. This evening after your off work if you can make it on such short notice, otherwise advise time and date that works for you.

Hi snowman,
Now that is one sad story and outcome. Yes bloody annoying that it happened but I bet he never does that again.

As for the varying compression ratio on the Mac the bearing are quite possibly babbit and are in the shape of standard shells but where this is different is that the 2 shells fit into what you know as a big end bearing cap, 2 of them. One of the caps is rounded as normal on the out side but the other is machined flat. The end of the con rod is also machine flat and long big end bolts hold the 3 pieces together. To cahnge the compression ratio you add or subtract shim between the 2 flat machined surfaces. This lengthens or shortens the over all length of the conrod. Standard has 2 shims and I will have to study up as to how many extra can be installed before it is too high and impossible to hand crank over to start. I know when this was last running it had 2 shims in place and that is what will go back in as a first start up. To change it you remove the top plate and the back plate and simply undo and remove the two bolts and add or subtract shims and bolt it up again. I can take a pic of it if you like.

Glort we moved from British Colombia to this province about 8 years ago our rural neighbors  decedents of the original homesteader immigrants from the Ukraine, Russia and a hand full of Hudson's Bay people.

Schooled in one room facility, most never been more than 100 miles from home. I've coined the phrase one room school house mentality.

Danny a bloke from Ontario bought a few property's in Erickson a half hours drive from where I live, anyhow Danny's at the landfill beaking off the the custodian about some realtor woman.

When Dan told me about the incident, I had to tell him that the realtor woman was the custodians daughter nd that living in small town Manitoba everyone is related either by blood or marriage.


Outsiders are looked upon as fresh money.

We had purchased an acreage, and had a neighbor who was a well driller come in to drill the well, test hole at 176 ft nice pea gravel coming to the surface with plenty of water but a bit salty.

Good enough for stock, a week later when pat and i visited the property the driller is finishing up and has his hand out for the money. I ask how many gallons a minute.

He says 3, I say wtf you were pulling pea gravel with loads of water, he says we dropped the screen at 156ft we could not get to 176 ft.

Told him to pull the screen and go home, not going to pay for 3 gpm.

Sent me a bill in the mail, threatening court action, finally I got in touch with the water management people in the bid city asking for drillers reports from the surrounding area.

As I'm interested in minerals had kept samples of the mud coming out of the well holes from various depths.

The guy from water management wanted some back story, told him the driller has possibly falsified his drillers report and that I was going to take him to court.

Never did receive any of the reports requested but the threats ceased to arrive in the mail, but in the meantime had been ostracized by my neighbors.

We never did move onto the acreage.

Very ingenious of the engineer.

Here is a pic of the piston and big end bearing caps and maybe some shims along with a heap of other crap that will become an engine. You can also see the Hvid / Brons injector along with a heap of linkages and levers with springs, this is the rocker gear and linkages that connect to the injector.

Way cool, thanks for posting the picture.

Definitely looks like a poured babbit bearing.

I haven't seen this idea used on any other engine I know of. Simple in design and practical as well. I found at the bottom of a jam tin that has other spare parts in it and sitting on the bottom is a full set of new rings. One less thing to source at a later date.

So far with the limited info in the only booklet I have on the engine compression ratio is not listed that I can find. You mentioned that the fuel can drip in and be squeezed to death to make it ignite, well maybe. This system had a fuel cup where the fuel is dripped into before getting down to the cylinder.
5 rings and they are all the same but they describe the bottom ring as being an oil ring and I guess this is because it is at the bottom where it will be in contact with the oil in the sump. It is also a horizontal engine and the specs claim it is all of 2.5 hp for this model.
There is a limitation to how many shims can be fitted before the piston will hit the valves but before you get that far you wont crank it over compression even when you use the decompression lever and drop it they will stop dead and you wont be able to continue to crank. There is a weird series of steps to take before starting up from the obvious, checking oil level (sorry snowman didn't mean to raise that again) to priming the oil lubrication system to get the piston wet and the bearings full, winding the engine backwards to prime the fuel cup then lift the decompression, crank away and drop the lever and if all the planets are aligned it will go bang and run. That was just a very general over view of the start up proceedure.

is that 5 or 6 Rings?

What do these things run? 50:1 compression??

Maybe works on the concept you can drip the fuel in and get it to light of you squeeze it hard and get it hot enough!  :0)

Six compression rings, no oil control ring.

And that is exactly how the new ring set is, all compression rings. I guess they feel that after all those rings bugger all oil is going to get to the top. Having said that I do have access to a company that specialises in the supply of pistons and rings and is fairly close to where we live so might do a trip to see if he does have a proper oil ring to suit.
