Now, That Was Just Plain Weird! 1066

Morning Guys,

Been summer fallowing with the 1066 for the past few days; darned thing just runs like a champ and pulls like a maniac.

Yesterday, at 11:45 I shut 'er down for dinner like I always do after letting it cool down for a few minutes. Okay fine.

Went home for lunch, came back and helped the neighbor fix his air conditioner on his tractor. Then greased up the disk before heading back to the summer fallow. It's now about 3pm.

Went to start 'er, and that silly thing would not start for nothing. Didn't even try to pop; just cranked and cranked.

This tractor has never, ever turned over more than one time and it's up and running. Hmmmm

Good fuel to the injector pump and the manual pump pressured up good....plenty of fuel. Cleaned the air filters. Tried starting with ether and still no go (come to find out, little 1/8" feed tube was plugged).

Anyway, took the air filters back out and sprayed either directly in the intake. She poped right off and ran good as always.

Put it all back together and it restarted probably half a dozen times normal as could be.

Will be intresting to see if it starts okay this morning when cold. What in the heck caused that?

The only thing abnormal about this tractor is that annoying "thump sound" at the air intake above the radiator. Been that way since I've owned it and I always thought maybe we've got a low lobe on the cam?

Tractor does not miss a lick. Whadda think?

"Supposedly", tractor had a new engine when I bought it and I haven't put 6-700 hours on it since I've owned it.

Alan,

Gremlins??? I would investigate the fuel shut-off. If this is a solenoid, a loose electrical connection could be your trouble.

The oil pressure operated overfuel starting plunger must of stayed in the run position. Might have to take the top cover off the pump & free it up if it bothers again.
Would check the valve adjustments for the noise in the intake. Older engines used to wear in the push rod cup or crack a rocker arm. Will find it on an intake.

Thanks Ted; gotcha.

Guess ya hit 'er on the head because the old sister ran flawlessly thru 60 acres this morning without as much as a whimper.

I can hear a light 'ticking' noise back around cylinders 4 or 5 so when it's cold and had planned on doing that "one day". Guess 'one day' is here. :>)

I do so appreciate your help.

Lashing the valves will help with starting, too. Make sure you have a spare quart of water with you, and if it does it again try dumping the water over the pump. The AC 190 and 7580, if you stalled them hot, wouldn't fire unless you cooled the little roosa master pump.

Hey dude if that pump gives any more trouble spend the money to get it rebuilt. If that old long stroke six Banger barks under load you ain't gonna like what it does to the rod bearings - been there done that on a 1466.

Seen a few early ones collapse the pushrod...might be the source of the noise. As for the injection pump, a sticking metering valve can cause the same issue you are having. Sounds like a reman pump is maybe in your future.

I'd lash the valves, and check for a worn cam lobe while you have things apart. Seen a DT414 work rod bolts loose s few times...and had one come apart on me. No more disgusting feeling than sitting in a hayfield, with the smell of hot oil and the tick of cooling metal.....
