Mike, the only way would be to find something like a Massy Ferguson tractor, or a Perkins generator/pump that someone was wrecking.

The boat engine conversion guys use Kubota engines of various HP. On that basis I'd say one should be readily available new, just pick the HP etc you need.
And pay the asking price.
Otherwise, shrug, keep in mind the old adage that you can have cheap, good and fast. You simply can't have all 3 on the same project. How long are you prepared to screw about to save money looking for a used but still good condition engine?
FWIW I don't like petrol engines either. In fact one of my happiest days on the property maintenance front was when I got rid of a POS Briggs & Stratton powered ride-on mower and replaced it with a baby Kubota diesel B7200 mini-tractor. So - I hear what you're saying.

I don't have any specific advice for engine choices but I'd maybe see what are popular in boats because they would want to be dirt simple.

Kubota, Isuzu, Mitsubishi, others. Older ones, Perkins but you'd need to be *really* careful dealing with an old diesel engine that came out of a boat. Salt water and machinery is a bad combination.
I actually have 2 3 cylinder air cooled Lister diesels that are surplus to my needs but too far away and air cooled so probably not a good choice regardless of distance. Might hook one up to a 7 kVa generator head taking up space on the floor one of these days.

[QUOTE]
This machine is used daily in a business , the only problem is that it has a Mitsubishi 4 cyl petrol engine .
It is owned by a business , mused for loading and unloading pallets of stock, and as you seem to be conversant in compliance issues , please give me a list of compliance requirements and i will let you know if it is .[QUOTE]
No I'm not a so called "expert" on the subject. All I can say is once you mention the fact its used/owned in/by a business then one must be aware of the compliance crap if the worst happens. Would be even more worried if there's, employees or members of the public within cooee. If the clipboard wavers can ping you, they will. They wont give a rats what you say if the fork is deemed to have unorthorised mods done to it. Your arguments wont hold up, unless you have the right info showing you have complied.
Most guys are backyarders around here, so my initial assumption was you were simply pottering around in your back shed, out of the gaze and off the radar of the Nazis.
I run a business. No I don't own a forlift.

I doubt there would be any issues with "compliance". A diesel is going to be a bit heavier then a petrol, thus if anything it will be able to lift more.
I wonder if RPM's will be a problem. Petrol motors generally rev more, although a small diesel will usually rev to at least 3000rpm. The ones in small utes are sometimes 4000.Gold, the colour of choice for the discerning person.

Penske powers systems are a DEUTZ distributor.
John Deere dealers will sell their industrial spec engines.
Kubota also have a line of small diesels.
any of these will have a suitable motor for you.

This post was reported and I have read every post looked at the rules and cannot find a reason why it should be closed.
The op desires a Kubota diesel engine.
Very likely he has some good results from Kubota in the past such as parts cost, availability reliability, etcetera.
If you look at his previous posts he is certainly no back yarder or DIY person. He is a professional providing repair and maintenance services for those companies who dig big holes in the ground and take out the black stuff.
I believe he is a single operator and perhaps for reasons of his own refers to the business without referring to it as his own.
If he works in his own compound/workshop the only person he could likely injure is himself. That part I will admit is not entirely clear.
It is an engine change by a professional who would have fitted many engines.
For those concerned about regulations and pointing out possible breaches perhaps you may wish to go to our electrical Forum and apply the same criteria you applied in this post to the diy electricians.
If you can source a suitable Kubota diesel engine, that is fine do it.
It is Christmas

Thank you to all who have replied with sensible suggestions , I have to keep this machine operational as at this time of year getting a replacement is not possible.
As Grahame said HAVE A MERRY CHRISTMAS break.

I dont think an engine change will breach any regulations and as Graham said Mike is probably more than capable to do an engine swap.
No structual changes will be done in any way to the fork, basically its modify engine mounts, fit the old fluid flywheel or clutch to the new engine allowing for the thickness of the adaptor plate, make a trans adaptor plate, a litte wiring, modify exhaust, fit throttle linkage and fuel supply, probable need to make a new bracket for the hydraulic pump.
What am i missing? None of this will change the safety or structural integrity of the forklift, if anything it will be safer as it will be more reliable than with the old engine. You could put a 200hp engine in it and the fork would still only lift the same weight as the relief would still bypass at the same pressure as with the old engine.
If there was anything that was done that could potentially be a saftey problem then in this instance you consult an engineer to do the comps and sign off on it for compliance.
Christmas cheers, shed

I was looking for suggestions for replacements which people may have done themselves, or have seen done .
The Title says it all replacing a petrol with a diesel, I am growing tired of the high maintenance which the petrol engines require to keep running cleanly , smoothly and reliably.
A machine like a forklift needs to be able to work when required , not have to clean the points or regap plugs which were only replaced a month ago .
I am like many business owners who work in their business , time poor , unlike people who work for someone or have retired , I dont have a few hours spare on the weekend or after work to continually , either repair or adjust a finiky engine.
The point of fitting a diesel is to free up some time for more critical work which pays money and retains customers.
I do agree there will be quite a lot of often frustrating work involved but the machine is size wise very suited for its application and where it operates, yes it has some age on it but its not worthless as I do not look at it as do accountants , i will possibly spend $3-5k on the swap , not including labour time as I do not charge myself for the time..
What I am looking at doing is 1. purchase a motor which will physically fit into the machines current engine bay.
2: carry out any repairs required , eg rebuild or other work as necessary as well as making any mounts to get it ready to drop in.
during this all changes to fuel and electricals will be done in an easily reversable manner.
3. remove the original without damage as it may be required is there is a hiccup with the transplant.
4. test run the machine , including a full check of all operating attachments as per normal legislative requirements.
5. put it to work for a couple of weeks then check for any loose or leaking hoses etc.
This is all happening while I continue to operate my business , so not a lot of spare time to worry about other minor issues.
Then there will be a few hours every 3 months for normal maintenance like changing oil , oil filters , greasing , checking brakes, tyre wear .
That is what I class as normal.

Hi Mike,
What is it about this engine that it needs the plug gaps reset every month? There are hundreds of millions of petrol engines in cars all over the world that run for years without having the plug gaps reset. Reading your previous posts it seems the ignition system is what causes you the most grief. Would it be easier to just upgrade to electronic ignition?Chris

Not going to happen as the distributor cap is getting hard to find, as well as the fact I prefer diesels from a safety point of view, no fire risk as petrol ones do have .
As I have said earlier this will be done over a few months as I have to source a physically compatable diesel then start by doing a total strip down on it to be sure it will be ok for at least two to five years with normal maintenance , not just a drop in change and hope for the best.
I also prefer diesels as they can be parked in the rain , started when wet and let idle until warm , then worked .
Petrols need to be kept dry and will bail you up in wet weather more than any diesel ever will.

If you just ring up the Kubota agents and order a new engine, you can save yourself a lot of time and aggravation.
As I said, good, cheap, fast - pick 2.
If you're determined to bottom-feed by waiting for the 'right' used engine to appear, you're really talking about this in the wrong place, you should be haunting Gumtree, machinery traders and other sources of used equipment.
Went through this exercise with a Yanmar marine diesel. Added up the cost in time & dollars to rebuild the engine based on what I knew, applied a bugger-factor for what I didn't, looked at the total and thought about the fact that I'd still have a high hour engine with components I didn't have the gear and knowledge to test (crack-testing a crank for example).
I bought a new engine. However you may well have more time and put less value on it than I do.

After unloading the last two pallets ,I decided to park it in its usual spot and while doing so , I noticed that it was leaving a trail .
On examination it was coolant , now the cooling system was due for a workover as the cath tank had a small crack in it and would occasionally weep a bit.
This was more seriious , so I dutifully removed the engine covers , disconnected all hosed to the radiator , hydraulic oil cooler was in the bottom tank.
Under the usual accumulated grime I noticed a wet patch about the diameter of a 10c, I cleaned the area and found that under the carefully smoothed and painted area was a 1c coin glued into a hole.
That is the type of "repairs" that I have been finding as I have worked my way over this piece of machinery.
Obviously in its past it was fixed by a shonky dude who did not care if the fix was permanent .
More work , however the radiator beinh out allowed me to remove the belt driven fan which was a bit noisy, another set of bearings as two years have passed since the last time.
I now have to source bearings as well as fix the radiator.
And people wonder why I have lost patience with the motor.
With all that has happened I think its time to modify this machine to make it reliable and easier to service , first the muffler will be removed from inside the counterweight , mounted up the side of the safety frame to get heat away from the fan bearings to give them a longer life, .
The fan may even be replaced with an electric one which is controlled by the operator as well as the temperature of the cooling system.
With no equipment dealers open until late this month I will have to repair the wonderful engine again, if anyone has parts in stock as i have noticed lately many parts distributors have to order what was once normal shelf items , eg bearings , gaskets . .
I think PDW's suggestion is looking like the way to go to save some grief.I will keep you informed of the progress.
Michael
