Cooling Problems

Last year I was in a pride and my 3318V and the hood was so hot you could cook eggs on it. How can I keep the heat off most of the hood? Or less heat on it. Ps check out the Eliot tractor and engine show in ME under events and gatherings posts.

Check for mouse nests under the flywheel cover. Unfortunately to do this the engine will have to come out. Also I don't think there is such a thing as a 3318{}. Somebody please correct me if I'm wrong

I've never had to take an engine out to remove the sheet metal...but I would check under the sheet metal for nest of any type and even the flywheel itself.

The airflow is easy enough to check. While it is running at mid throttle, the airflow should be easily noticed at about 2 ft by an open hand. Nevertheless, the fins should be periodically checked for obstructions. If I recall, that engine should have a special generator pulley that has fan blades in addition to the normal flywheel. Check that it is present. If not, add it.

I have noticed that of all my tractors, my 3410 with a briggs runs the hottest. Seems it has something to do with the briggs engines in an RBT. I think the generators get kind of hot and may also contribute to a hot hood. My FDT's with briggs run cooler, as do my RBT's with Kohlers. I went to the trouble of removing the engine to check for nests but found no major debris or dirt on the engine, appears to have never even blown a head gasket. So my assertion is that it is: 1. tractor airflow design 2. timing issue. 3. exhaust valve issue Haven't been running it much lately and haven't been able to dig into it yet.

No the 14HP died.

The RBT/heat issue is very much related to the muffler being housed inside the grille. The cooling air from the engine blows across the muffler/exhaust piping, making a hot front end. The FDTs don't run into this because the mufflers are outside the chassis and there are not many shrouds.
