Tooth bar!!!

[stormpetrel]

Mounted the tooth bar; started digging a pit to burn all the brush we cleared and piled w/the grapple. The next best thing to heavy equipment!! and only 26 hp!! I was very surprised and gratified that I was able to get a full bucket of dirt with every pass, the thing worked better than I expected. Very useful.....I love it!!

The bad news? My engine is definitely overheating. I "shot" the cylinder head with an infra red thermometer and got 190 (!) So....back to the drawing board.
It seems worse than before. Someone recommended flushing the radiator, maybe I'll try that first. Otherwise, is there any way to rule out the water pump, or otherwise test it?

BTW, my eleven year old son, Andre, got his first seat time. Taught him how to operate, as I walked alongside to make sure there were no mishaps. He loved it.....nice!!!!

Nice looking work:thumbsup:

I don't recall what all you did in the way of the temperature troubleshooting but have you checked the radiator with the cap off at about 1500rpm? My 1900 has a lot of water flowing at that rpm. I ran it today for about 3 hours pushing dead trees and digging up brush and the engine barely got warm to the touch on the head and block. I don't have a thermostat so that is probably why. Radiators tend to get plugged up at the end farthest away from the return line and you can't see it except the flow will be slower when looking through the cap. At that rpm it should look like a river flowing past the cap.

Very cool, glad you shared.

What makes you concerned that your cylinder head is 190 deg F? That seems well within the acceptable range to me.

The operating temp should be no higher than 170.....the water was more or less boiling!!

I'll try Gary's suggestion, and run her at 1500 RPMs and check flow.

Why do you think it's running hot, and what does "more or less boiling" mean? Head temp, (500-600* depending on where you check), has very little to do with water temp. Where did you get the 170* figure?
Actually I would back-flush the system only because of not knowing when it was last done.

Sure does make project list heck of alot easier...nice burn pile for holiday winter night

I'd say your son has nack for operating..less seat time for dad.

Someone posted a link to the 2210 engine operating temp......150-170 was the range. The radiator was boiling over into the bottle after it was shut down. I "shot" the water with the temp gun.....low 200s. Overheating.

The guy who owned the tractor before me was meticulous; had flushed the radiator a couple of years ago. He had also rebuilt the front axle seals, one of which now leaks. So I guess a 30+ year old radiator might need a little attention......

Are you building up pressure in the cooling system? 190 200 is ok as long as you have some cooling system pressure, which raises the boiling temp of the coolant.

"The radiator was boiling over into the bottle after it was shut down. I "shot" the water with the temp gun.....low 200s. Overheating."

That's a lot different than 190* at the head. I would back-flush, replace rad cap if not new, no help, replace head gasket.
