Lister TR3 Overheating
« on: November 03, 2017, 11:58:18 AM »
Hi guys
So I've stripped my engine back to the crankcase, cleaned everything,  replaced all the gaskets and fitted new injectors but the thing is still overheating for some reason. It had also had new oil, fuel, air filters and fresh oil.
It starts and runs fine but then cuts out after about two hours.
Any clues?
Thanx for your time
Allan

I would need a little more specific information to make reasonable suggestions...

What is the air-flow like? Sometimes the fan blades get dusted - if they have lost the concave shape to dirt, then they will not move as much air.

What are your timing settings? What are the individual exhaust port temps?

How much load is the engine pulling?

Also if the engine is operating in an enclosed space, does the engine have a supply of fresh air, and is the hot air that exits the engine sufficiently ducted away from the engine to prevent re-entrainment into the supply air stream.

Specifically, how do you know it's overheating and the overheat is causing it to stop?

Does it have a reliable/ confirmed gauge? Any other signs it stops because of over heat specifically.
Could it be something else like marginal fuel supply that eventually slows and becomes insufficient.  Id it in an enclose area where the exhaust and air are not properly vented and the thing runs out of oxygen ( and also gets hot)?
Could it be something like the load the engine is driving increases?  Bad bearing that gets hot and increases drag, something else that loads up or blocks and gets harder to turn till it stops and lad falls off till it runs and eventually builds again?
Insufficient clearances, when engine heats up tight clearances close up more and hold a valve open or cause other drag.

Takes a lot to get an air cooled to get that hot and not do damage.  I'd first certify it IS actualy stopping because of over heat and then verify its not the load the engine is driving  rather than a fault in the engine itself.
