Should the Turbo Glow Red on my combine?

I have a CR 9070, new to me this year 2009 reg, on the first day we used it in wheat when it got dark I pulled up beside it to take a load and could see a red glow from the engine bay.

It had melted a bit of the engine wiring loom, and the Turbo had cracked internally between two ports were it bolts to the manifold.

Also i found a leak in the intercooler piping which could have caused it to get hot in the first place. It's defiantly running cooler now but I can still see a red glow when it's cutting in the dark at 100% engine load. Is this normal, anyone know what sort of temperature the turbo/manifold should be at when working at 100% engine load.

Seems like a fire risk to me but the dealer thinks it's ok. I'm a bit worried they want it to catch fire as they don't seem to know how to fix it!
 
when an engine is working hard there is a lot of heat to dissipate from the engine, that heat must go some where, the turbo is the 1st port of call, so boy does it get hot, that dull glow you see in the dark, is nothing to worry about, but the intercooler pipe would not be helping, that is why it would be a little hotter than normal, it should be ok as is, unless someone has up the fueling for more power and gone to far

Yes it should ...........

After now reading the original post
Edit:
Only thing you can do is keep the filters clean (fuel and air) and reduce the loading when you can.
Double check your coolers out front for restrictions. Also fan drives?

Yea I know older vehicles can have hot turbos but I would have thought that on a combine they would try to keep things cooler to reduce the chances of fire.
 
I would say: normal for the turbo to glow red under high load; in the dark at least.

Infra Red Thermometer is the best way to tell for sure whether temps are excessive. Easily bought for about £50.

Normal for the exhaust manifold to be glowing the most, and the turbo too, at full chat. The intercooler leak would have been making it work harder and exhaust temps would have been higher with slightly less air throughput (result of slightly poorer combustion)

Turbo chargers usually glow due to heat.alot of old tractor silencers did too.usually ford 4000,5000,7000

I remember using a Ford 5000 engine installed in a Sanderson rough terrain forklift, fitted with a torque converter, at night in a muddy potato field loading boxes of spuds. Not only was the manifold and a big band across the silencer glowing bright orange but there was a short cone of orange gas blowing out of the exhaust when working at its hardest. It was relatively clean [for a Ford] during daylight.

Most people don't appreciate the effectiveness of the intercooler in cooling and therefore shrinking the inlet air. This lets more oxygen into the cylinders for a cooler more efficient burn per unit of fuel used. I've seen blocked fins on intercoolers result in fault codes, reduced power, increased engine temperature and fuel consumption.
A leaky intercooler pipe would result in reduced pressure and flow of air into the cylinders, resulting in more smoke, less power and increased exhaust gas temperature and fuel consumption
 
know its not a combine but this is what happen when you push a 660Hp merc v8, 130 litres of diesel per hour

I'm not the only one then, are you happy with it running like that, (I take it that is a combine).
No not a combine, its a jenz shredder which works in wood dust all the time. The exhaust was never the cause of the the many fires that engine suffered it would always start in the v of the engine then burn through the fuel lines, but it was always put out before it went up proper. Their new machine is a straight six because of the number of times it happened

New report underlines need for joined-up action to protect rivers

Written by Defra Press Office

A wide river is in view in a valley in the background, a drystone wall is behind the river, and large, green trees are prominent in the scene.


The Rivers Trust has today launched its State of Our Rivers report aiming to allow the English public understand and explore the health of their rivers on a national and local scale.

Environment Minister Rebecca Pow and Environment Agency Director John Leyland attended the launch panel to discuss the ways in which the...
