Very interesting story scalyback. I was not aware of those details so it would be a very rare engine if one ever turned up here in Oz.

I too look forward to what needs to be done and how you approach and solve the prolems.

I tend to remember similar info for the Lister engines. Do a search of the forum in this section and see what turns up or a Google search for the same info. There are members on this forum that can help you for certain but not all visit on a regular basis so it helps to have patience.

I also meant to say to not use synthetic oils on these old girls, they are not designed for it.

Hi mate and welcome to the Forum.
Sounds like a nice toy, I have a Liner Roughrider dumpy with a twin SR2 Lister in it.
You are right about the oils and changing them, I have usually also flushed the gearbox and diff out using diesel fuel and driving it on rough road or up and down some hills then drain and fill with nice clean fresh oil. Here in Australia I use straight SAE30 oil and I believe that is good for you but maybe a bit heavy during winter time. The only issue would be harder starting because of thick oil but on a single I think you will be fine. Dont forget to do the air filter as well. Not sure if you have done so already but I would drop any old fuel out and start with fresh stuff.
I am not familiar with the Petter diesel but someone will confirm if there is a cold start position on your engine as there is on the Lister. Go around and adjust your brakes and that means the hand brake as well. Grease the dumpy from front to back as this will make your steering a bit lighter as well after doing the king pins and tie rod ends even the centre pivot bush will need a good feed of grease.
As for dating your dumpy someone will be able to help from your serial number also if you could post the HP which will be listed on the engine itself if not the build plate if it is still there. They are a heap of fun to own and I fitted an extra seat for the missus to get on so we both can have fun together.

Hi again Paul, I just had a quick look further up the page and this Forum has a dedicated Generator section and the second thread on the current page is discussing a H series Lister with generator.
While waiting for some help here maybe have a quick look through that section and see if there is any help. There is another generator thread running in the  Engines section but he has a different problem but is receiving help help 2 members who may be able to help you out as well. Have a read there and send these guys a PM and ask if they can help you too.

Sorry Paul. Yes your link does work, I must have read your replies in the wrong order.

Thank you for your very kind wordss but there would be no way I could have done it with out the enormous help from members on a welders forum who knew wha to look for and there for they guided me through the repair.
Yes, my electric soldering iron was like using a sledge hammer on a thumb tack but with persistence I got there.
The capacitor measured 2-3mm in length and close to 1mm in width. So small I 'borrowed' Dees tweezers from her sewing machine to place and hold it while I put a tack on one end.
I only had a go at what I was advised to do by people who have the 'smarts like you' on what to look for and do. I am proud that I actully did it but I do not understand what it is I did as electronics seem to avoid my b rain pettern and wont stay and allow me to understand them. As to have the ability to reverse engineer circuitry, now that is a true talent and IO tip my hat to those who can.

Hi Paul,
Pictures must be compressed to add to the Forum.

Never ask me about electrickery but having just repaired a circuit board on my MIG welder today after 6 weeks of looking at it, finding issues with a diode, a small capacitor and finally the relay switch it is working again. While I was waiting for the relay to come on the slowest boat from China I spent a lot of time at the work bench with a desk lamp and a magnifying glass searching for suspect 'dry soldered' joints and found some joints I was not happy with so a quick touch with the soldering iron and a dab of solder and that was sorted. It was the use of the light and magnifying glass that found the capacitor problem and the diode was an obvious failure.
I used mineral turps to wipe over the board but my board did not have this wax covering. If you were here in Oz at the moment you could leave the board out in the sun and wipe off the wax as it gets the solar treatment but I am guessing you are near snow conditions soon so that is not an option. Acetone might be another option as to dissolving the wax but check with the guys if that would cause any issues.

I am with you with the electronic department, it is all something very different and tricky to get my head around. At least you are prepared to have a go at the repair with guidance. Bob should be able to help you the most and to have the ability to reverse engineer electronics is something made of nightmares in my book and comes easy to others.
I would do my best to resurrect this generator and board as the new ones are not as well designed and built to last. I look forward to following this repair and outcome, good luck with it.

Welcome to the Forum.
As suggested take the circuit board out and gently clean it up using the least damaging solvents possible. Try it on an area that wont matter if damage occurs. Clean dry soft brush first even using compressed air to aid the cleaning. Electronic stores sell aerosol cans of solvents suitable for cleaning circuit boards but still be careful using them.
The last thing to do is give up on these well made old generators nothing new stand up against them on build and quality. I know very little or less on electronics but I have been coached into attempting a fix on a circuit board on a MIG welder. I now, almost know how to identify a transistor, capacitor and diode by reading the board. I still have a long way to go to work out what the values are or mean but with time and patience I am going forward.
Freeing up the brushes in the brush holders is very important and I mean 'clean' not just so they can move in and out. Also the contact surface on the armature must also be cleaned up using some fine wet n dry paper and I dont use any water when I have done these in the past. New brushes should be readily available and if not easy to get a hold of I have bought some that were a little bit bigger than the originals and filed them down to size. Like anything the cleaner every thing is the better it works and also runs cooler.
Look forward to seeing more pics of the generator and the board.

Engines / Re: Lister SR2 fuel filter
« on: October 06, 2021, 04:32:33 AM »
Sounds fair running it with 2 filters. I have a large tropical high speed 8hp Lister that had no filters.  So I fitted a water separator and filter from a truck. This gives me the chance to see any water in the glass bowl and easily drain if I ever see any. So really any sort of fuel filter will work on these brilliant engines so long as they are replaced as required. Good luck with your repairs and let us know how you get on.

If the threads are in good condition no sealant is required. I have been in the situation where a sealant had to be used so I used a product calle STAG Joint paste. I applied it to the thread and tightened the joint and left it 24 hours to sure and that worked fo me.
With the banjo fittings the new soft fibre washers are what makes the seal not the thread so again with the washers no sealant required.
Some fuel lines use an olive fitting which compresses onto the fuel line when you tighten it up. If the fuel line is sitting square in the hole and the seats for the olive to sit into are clean then this should seal fairly well with a slight chance of a leak past the thread.
That was very good advise to NOT use the PTF tape it is not recomended on fuel systems.
Other products are out there and from memory the Loctite range have a very good sealant which is like a gel and use it as directed and it will work.
Is there any reason why thi engine has 2 in line fuel filters? I believe that one is enough.
