Engines / Re: SL1 stalling warm
« on: October 01, 2020, 10:05:28 AM »
Hi Guys, very puzzling. I very much doubt that the timing would be out enough to stall your engine, if it was I don`t think it would start from cold. You do say that you have replaced the injector pump, these are timed by adding or removing shims between the injector pump and the crankcase, you should have checked the spill timing when replacing that unit. While you are at it ensure that the rack on the injector is moving freely and not binding.

Mike is possibly right about overheating. These have an air cooled cast iron cylinder with a lot of cooling vanes on them, cooling air is ducted through these vanes from the flywheel which has a fan cast into it`s face. The ST1 engine I have been working on had all of the cooling vanes filled with oil, dust, mouse sh1t and etc. It is a pretty simple job to remove the cylinder head and then the ducting shrouds around the cylinder, a little work with a screwdriver and an airline should clean out the cooling fins.

While you have the head off, check the condition and seating of the valves and clean the valve stems, diesel engines that have little or no load tend build up a lot of carbon on the exhaust valve stem, this can lead to stalling as the exhaust valve does not close properly and you loose compression.

Another possibility that occurs to me is operator error, When starting these engines there is a lever attached, through the crankcase. to the fuel injector rack. When starting, that lever needs to be in the vertical position, this over fuels the engine making it easy to start. When running, the lever needs to be in the horizontal position. To stop  the engine push it as far down as it will go. An over fueled engine might quickly overheat or clog with carbon.

Lister Based Generators / Re: Wiring a doghouse

Hi Guys, before you do anything else please check the condition of the selenium bridge rectifier and the two wire wound resistors that are hidden behind the plastic air vents on the generator head, I would also recommend replacing the charging rectifier in the dog box.

Hi Guys, diesel fuel comes in many different types but generally it won`t start to evaporate/vaporize until it gets to around 150 centigrade. Water cooled diesel engines run a bit below 100 centigrade to stop the coolant boiling. Air cooled diesel engines run at around 110 centigrade and are consequently more fuel efficient. There is nothing in the SL that should cause fuel to vaporize in the fuel lines. The fuel tank is external and coupled to an external fuel filter, there is a steel fuel pipe that runs from the filter to the injector pump via a slot in the upper crankcase door. The fuel temperature should never be able to exceed the crankcase oil temperature as the oil flowing to the cylinder head returns to the sump inside the upper crankcase door and over the injector pump and incoming fuel line.

Hi JP, an interesting problem you have there. Have you checked the tappet clearances? The ST1 I am working on has a clearance of 7 thousandths of an inch to allow for expansion of the push rods and valves as the engine warms up. If this was set too tight you might find that you loose compression as the engine nears it`s running temperature.

Hi Jake, welcome to the forum. A very nice find you have there. Mike is right, if this has been submerged it will require cleaning out. He is also right about pulling the injectors, you may well find that the engine is Hydro-locked if one cylinder is full of water.
Once the injectors are out, try turning it over again. Another likely cause of it being seized is that the armature in the generator head maybe seized. Remove the generator head and see if the engine turns over.

The inside of my ST2 was a lot worse than what I am seeing in your photos.

Thanks Cobbadog, we know the fish co-op rather well, been going there for eleven years now, much better now the walk along the breakwater is open. Sadly they are not a source for waste vegetable oil, they cook everything in animal fats from the abattoirs. Still tastes bloody good, to hell with my coronary arteries!

Hi Guys, further to my starting problems with the ST1, the new injector pump element arrived yesterday from the UK. The price was about a third of what I was quoted in Australia, delivery was about ten days, not bad in covid times. So hat off to the Supplier, Royal Mail and Australia Post.

Fitted the new element, bled the fuel lines and injector. Had to hand crank it twice before she ran but not bad for a 40 year old engine. No smoke from exhaust and no oil leaks she`s a goodun!

Generators / Re: Brush generator
« on: September 15, 2020, 01:47:41 PM »
Hi Phil, and welcome. could you give us a bit more to work with please. What was, or is your Brush generator driven by? Does the unit have a starter motor or is it a Start-o-Matic type?

The SOM variants have a starter motor/dynamo built into the generator head. If you look inside you should see a couple of brass slip rings and also a commutator (segmented) ring. These units have a main field, a series field and an auxiliary field.

Does it look like this photo inside?

Hi VP, glad to see you are still hunting down valuable old relics to restore. I know where there is a beautiful Southern Cross engine and pump, sat next to a dry creek and overgrown with weeds. I want it but the owner doesn`t want to part with it. I guess it will still be there ten years from now.

Good luck with getting your hands on the engine,

Bob

Hi Alan, I have a much later model Lister SOM connected to my workshop. I have a single 60 watt incandescent light bulb, with a switch connected across the 240 volt output. To start it I just turn on the switch, once it is up to speed, I then close the main circuit breaker and run whatever I like off it, including sensitive equipment like computers, TVs and telecoms equipment. To stop it I turn off the main circuit breaker and then turn off the switch to the 60 watt light bulb. Works a treat, cheap and simple.

Hi dpehrson, welcome to the forum.  If my memory serves me correctly your engine is : unit 1210 HR4 anti clockwise made in 1978

For parts in the USA you should contact Gary at Diesel Electric Services or Central Maine Diesel. Here is a link to the UK stationary engine parts website: https://www.stationaryengineparts.com/Lister-HA-HB-HL-HR-and-HW-Engine-Spares/

Good hunting,

Hi VP, I`ve been off the Forum for about ten months. Looks like you have been busy and the quality of your work is now spectacular. I`m loving the oak frame and cast iron wheels on this, I do hope you are going to be showing some of your engines at local stationary engine rallies.

I now have satellite internet access and phone communication but it is very slow, expensive and limited in band width. Working hard at cleaning up the mess left by the fires and getting approval to build a replacement house.

Hi Veggie, when I installed my ST2 startomatic the exhaust noise was way too much for my Wife. So I went and bought a dustbin, I dug a hole and dropped the bin into it. I connected the exhaust pipe into the top of the bin and fitted another flexible pipe to the bottom of the bin. I dug a trench about 20 feet long for the bottom pipe to sit in. I then surrounded the whole thing in concrete and put the top soil back over it all.

The exhaust is now silent, more than can be said for my Wife.

Hi Glort, as tempting as it might be to break all their fingers with a large hammer this will not stop them. They will just apply for and receive some sort of state funded disability pension, along with voice activated computer/telephone technology and carry on where they left off. Only difference is they will now be supported by the state and some people will feel sorry for them.

Public exposure and humiliation are the only deterrents that work. Sadly our ruling classes are too busy trying to cover-up their own indiscretions to worry about spammers.

Hi Guys, I have to disagree with Glort about doing them grievous bodily harm, I watched a couple of Youtube videos of computer wizards turning the tables on spammers, deleting all their files and destroying their computers, far more satisfying and lasting than just punching them!
