If the engine has been running for some time with the centre bolt loose the maybe the pin sheared off.

Yes thats exactly what I thought.

Here is the diagram of how it fits together. I would think that anything you could find that is a reasonable fit into the hole would work. Hopefully if you can stop any movement then the centre bolt will not work loose.

Yes I would have thought that would be fine. The only problem I can see is that the holes in the lever appear worn. There should be 3 distinct holes, but I looks as though 2 of them have broken through. I will have a look. But probably be tomorrow now.

I checked this in my technical bulletins. They list all the mods for all the models. Its what Lister R&D department used to issue to us service engineers among others.

As a follow on if its any help, I have just checked through the technical bulletins and the pin part no is 027-10103

You are quite right and that lever should have a locating pin fitted. I think it is a case of which parts manual you are using. The lever you have there is a later modification so if your manual is from an earlier date it won't be shown.

Thats the one. If you look carefully at the photo you can just see the other pipe. If you look you can just see the two 90 degree elbows, which are flow and return.

Beta and Nanni both fit the caloririer in different ways. On the Nanni engine they just seem to cut the water pump bypass hose and use this as the flow and return to the calorifier. On the Beta they would normally take the hot water from the rear of the cylinder head and the return would tee into the engine return from the skin tank. This take off from the rear of the head would have a restrictor fitted so as not to still ensure good engine circulation.

Possibly a small amount of air entering the fuel system. Or maybe a little stiffness on the fuel pump rack.

I think you are right . It does sound to me as if the marks are correct. I think they should just be left alone.

There seems to be a lot of talking at cross purposes. Firstly the position of the line on the fuel pumps determines how much fuel the engine can use at full speed and has nothing to do with idle speed. To set the lines on the pump(g setting) you would use the correct size feeler under the stop lever, loosen the small bolt on the back plate and rotate until line on the rack aligns with edge of pump. Therefore when the feeler is removed the line will disappear inside the pump, so what you have is correct. Now the small spring you have on the rear pump is the idle spring and if you undo the lock nut you can turn the collar to adjust the tension which alters the idle speed. To adjust correctly you would totally slacken the idle screw on the speed control lever. You would then tension the idle spring to give a speed of approx 800 rpm and lock in this position. Then using the idle screw on the speed control lever increase the speed to around 850 rpm (recommended idle speed for this engine). That is about it.

OK thats fine. Probably best to post here as it my be of interest to others. Unless of course I am told anything different.

As I said in the earlier post I need to see the complete flywheel end injection pump showing the whole linkage. The photo you posted only showed half of the pump.

I think by the time Listers were doing the SR engines they were not used.

As Tony Brooks said check for pipes going down to the pumps. I did forget to mention this. Although to be honest I think these were used more on industrial engines. Very rare on a marine unit. We need to see the other side of the pump in the photo.

There are no washers where the leak off rail fits into the injector. Just undo the nuts and remove. It may be necessary to remove the injector clamps to allow the pipe to be lifted out. Basically should be ab easy straight forward job.

Items shown are the components and adjustment of th idle spring. This is found behind the fuel pump housing door fitted on the fuel pump rack on the rear most pump. Basically you would set this so the engine runs a little slower than the recomended idle speed. Then on the speed control lever increase the speed to the recomended idle.

Post a picture of what your looking at and may be able to advise.

After a quick look at ebay it seems some have the threaded fitting forward and some have the fitting to the rear of the engine. It seems like a lot of these parts are some sort of copy. To my knowledge all genuine Lister SR leak off rails would have the thread at the forward end.

As Tony Brooks has said the reason for the pipe is to allow any air trapped in the fuel filter to return to the tank. The engine will work without but could cause you problems if any air is present. Lister would always fit this pipe on engines fitted with a fuel lift pump. On gravity fed engines it was not fitted.

There is no drain plug in the adaptor. Any water around the fan will not cause any problems, it will just get blown out. When these were used as lifeboat engines one of the tests was to run engine sat in water up to the crankshaft level. Engine would run well and just blow the water from the air duct.

The hole just goes through to the inside of the fuel pump housing and timing cover. Inside behind this hole will just be the speeder spring, governor linkage and camshaft gear. As I said just blank it off to stop any oil seepage. The hole is not needed.

In image no 1 the hole should just be blanked off. I think this may have been done with a small core plug rather than a bolt. Check to see if there is a thread in the hole. If there is you can use a bolt but ensure it is as short as possible so as ot to foul anything internally.

In image no 3 that would be correct. With the lever in the stop position the marks will dissappear. This is where the g setting as given in the manual comes in. You would put the correct size feeler gauge under the stop lever, then the mark should be just visible.
