Lister D??

G'day Team,

What have I got here??

I thought (and still think) its a Lister D - but I've not seen the Hopper/Valve Covers like this before.

Its only got a small hole in the cover - see the photos.

BTW: I'm currently over 1000 kms away from this engine - so I can't check Engine Numbers etc.

Ideas?? Thanks.

It's is a D type. The Hopper cover is for tank or radiator cooling and the hole should have a thread to allow for a pipe to be fitted . The lower pipe would have come from either the plug above the flywheel or where the drain tap should be just above the spec plate.

Thanks for the info

Is it correct to assume I can just fill the hopper with water and run it like a "normal" D Type? Or perhaps just replace the Hopper cover with the large oval hole type and run it without the tank/radiator?

It's perfectly OK to run the engine like that. I would check that the plug above the spec plate can be unscrewed otherwise you won't be able to drain the water.

Nearly right.

Yes it's a D with a tank cooling top, these can be a stand alone tank like the Petter M, larger Listers like the C/S etc, or one bolted onto the engine. Radiator tops are different.

Sorry to belabour what is probably a simple thing......

I think its obvious how the Hopper version works - you fill it with water -Hey Presto - water circulates and cools the engine. I assume it circulates just on the Laws of Thermodynamics - as the water in different parts of the water jacket heats and cools - small currents build up to circulate the water.

But with the Tank version - how does the water circulate - I would have assumed it needed some kind of a water pump to circulate water from the tank to the head/water jacket and then back to the tank. I wouldn't have thought convection currents were strong enough to take water back to the Water Tank.

Does the water tank version have a water pump that the Hopper filled does not have??

All done by the basic laws of physics, hot water rises and in doing so draws cold water into the bottom, as long as the top hose connection in the tank is covered with water then it will circulate.

Thanks heaps for the info - and thanks also for the photo - will serve as a really useful reference when I get stuck into the old Beast.

What does the spec plate read?

No rush, when you get a chance....
