Converting to diesel

Do these little diesels need to keep a constant prime like our big trucks do?

Or can they just pull up the fuel through a formerly empty line like a gas engine?

 

Good question, I believe they do need a constant prime. You want to avoid as much air in the system as possible to prevent wear to the injection pump.

If using a remote tank, wonder what would be the best rated electric fuel pump for the diesel? 4-7 psi?

Have just brought this L70

 

Managed to get an electric start one.

 

It comes with Generator so might be able to mate the Robin DY23 to that and sell it.

 

Also could use the trolley as my mobile welding station and just scrap the generator, or sell t for whatever I can get.

 

Picking it up in Thursday in Edinburgh on the way home, hopefully it all goes smoothly as haven't had the greatest of luck in my quest for a diesel!

Woke up this morning thinking about what to do with generator unit and the obvious solution hit me.

 

Engine into wheelhorse

Generator trolley turned into my new welding trolley

Generator attached to a quick hitch and mounted to front of wheelhorse!

 

So obvious, and that would mean my welder could then be taken anywhere on the farm if put into the trailer behind the wheelhorse - the same machine that then provides power.

 

Super excited now!

Great line of thinking there Dan. 

Makes use of everything. Keeps all of it practical. 

 

 

Sooooooo..... Ya done yet???

I love the idea but I fear there is one fly hovering over the ointment....

Most generators of the type you pictured have only one armature shaft bearing--at the end away from the engine. They rely on the engine's "PTO" side bearing at the other end (the tapered engine crankshaft end assuring perfect alignment with a cone end on the armature shaft). You'll have to wait and see how that one is set up to be sure. Fingers crossed it's a two-bearing genny.

Very good point Don, but that's ok if it doesn't work out - only really needed the engine. 

 

The 5hp might be compatible to the generator even if it couldn't produce 5kw - mate them together or something. I'm sure you guys will be quizzed mercilessly on options!

 

I'm so bored this trip on the ship - tons to do at home but stuck twiddling thumbs here until Thursday.

 

Have made a stupid project/present for one of the young trainees, he has just got a full-time job, and left home. But that's no substitute for working on the wheelhorses

There two ways to conquer this task toy. 

1. Intelligent reason. 

2. Brute force. 

Both accomplish the desired end of getting the hand held pieces in the box. 

 

It is likely not a good idea to share this information with the recipient of the device.

I had a very strange idea that there may be some way to support the "taper" end of the generator. A "U" holding a cross-shaft on two bearings to give it stiffness--at one end, the taper shaft into the generator and at the other the pulley to the Horse. Not as efficient as a generator with build in, side-load capable bearings but you are an innovative fellow!

He will be option 2, intelligence is not a strong point!

It ain't easy he,  Searched quite a while for my lombardini.

Often there are just no good candidates or they are +€1000 used.

Certainly the prices can be crazy for a used engine, and half of them dont even look in good condition.

 

Must have looked at every type of single cylinder engine ever invented!

 

I really like the look of the Duetz air blower system, but the Yanmar seems the best fit for the hood.

I did a quick search and there appear to be a few solutions to the single bearing issue. One guy just used the shaft and lower engine casing of a blown engine to act as the second bearing, then attached the belt to the crankshaft - I think he cut it short and machined the remainder to take a pully.

 

I'm sure we can bodge something together, the project is all about improving mechanical knowledge so even a failure is a success!

that's pretty cool indeed

the Yanmar

those are the simplest and easiest to find parts for, for a diesel pretty those are refined engines

It's just that they go for high prices, The cheapest I have ever seen them was €700 used for an 10 hp.

The Lombardini was a lot cheaper and I do prefer the sound, it sounds like an old tractor.

Picked up the Yanmar generator, pictures to follow as it's been a long, long, long day. 30 hours with only 2 1/2 hours sleep - last day at work always ends up being a test of endurance.

 

Annoyingly I just found a diesel wheelhorse about 2 hours from me for less money than I just spent!!! I actually drove past it today on the way home. He said engine fine, but clutch issues......ahhhhhhh! It will be simple to fix I'm sure.

 

Anyway, don't have any spare cash so going to cry myself to sleep tonight.

[ebinmaine 67,466]

No worries bubba.

Ask Jeff if he will ask the treasurer if you can have a loan...

 

I'm sure the answer would come back as 'expletive no'... but... maybe Jeff can work on her...

This could work.

Ooooooooooooooo.  Excellent group.   

[Dan.gerous 2,696]

Have quickly thrown the generator back up for sale, guy coming around to have a look tomorrow.

 

Probably by the time it sells the 512d  might be sold, but worth a try.

 

He says clutch not working, not sure if that's PTO or gearbox clutch.

 

Also hedging bets and put one of the C125's up, it's got a good side discharge deck so might go quick enough to get a deal done.

Pictures of the generator.

 

It's sounds beautiful when running, and incredibly quiet - not as loud as the Kohker 301

 

Key has been mangled by worker thugs, but you can use a screwdriver.

 

Had biofuel and cooking oil in it, so a bit smoky when cold. Flush it all out and replace with fresh diesel if I don't sell it.

 

At new house now, nowhere to work and it's pouring with rain. Need a garage ASAP

That is good to hear, I briefly had a Yanmar L100. It was definitly louder then any of my kohler's. I mostly don't wear earmuffs, but when that engine ran, I  immediately put them muffs on. Had the stock muffler and everything.
