Steve,

First, Welcome to the Cletrac Discussion Forum.

The AG-6 was produced from 1944 to 1953.  

Let's pull apart the model number.  The "A" indicates Cletrac Model A.  
The "G" indicates gasoline engine, and the 6 indicates it's a six-cylinder.  
I believe the "H" designates it's a "Hillside" version - meaning it has wider track spacing.

Based on the info I have below, Your AG-6H is a 1947 model.  

Year   Starting Serial Number
1947   3X4586
1948   3X6062

The 6-cyl gas F226 L-head engine was built by Continental Motors, and is 226 cu. in. displacement.  

L-head: A flathead engine having both valves in the block and on the same side of the cylinder. The arrangement of the valves in the block and the combustion chamber forms an "L" shape.

This engine-family powered the Massey-Harris Model 44-6, as well as Kaiser, Frazer, Willys, and reportedly, some Checker Cabs.  See my posting with other info on the engine.

The ouput should be about 90-105 Horsepower.

Good luck with it!  And ask questions - There are a lot of knowledgeable folks just dozin' out here on the forum.

Thanks John

I have an AG6H also with serial number 3x 5790 so it was made the same year.  My question is who makes the best manual for this model?  I need srpings and linkage for the governor so that I can set it to something other than wide open or idle.

[John Schwiebert]

First of all does your crawler have the original governor. The governors were made by another outside vendor. Have you had the governor off?

[John Schwiebert]

On Steve's posting on horsepower. They are closer to 30 Horse Power. Remember in the time of the AG crawler the D-7 Cat was close to 100 horse power. I will be  home for a couple of days so I will try to look it up. The Massy 44-6 used the larger F244 engine and 3-14 plow is a load. A model A crawler will probably also only pull 3-14's Questions?

[G Huffman]

I have not had the governor off.  I just got the dozer last month and finally got it started.  Who made the governors anyway?  I looked in my tractor books to see what others were like but did get some insite on adjustments.  The engine is rated at 100 horsepower.  This is not counting any lossed such as generator and other equipment.  It would probably be rated 25-35 brake horsepower.  I will check the specs for the Kiser automotive modle to compare them.  

I am still looking for info on the different manuals though>

[John Schwiebert]

You guys are not comparing apples to apples here. The industrial engines are F-226 engines. The automotive engines are FA-226 engines, One major difference is the automotive engine is running at higher RPM's, has a chain driven camshaft and may have a different compression ratio and does have a carburetor with different flow. I just checked my I & T manual and in the spec sheet as well as the Continental add, maximum horsepower for the F226 engine is 71 at 2800 RPM. I then checked the specs for the AG-6 crawler.  Engine Horsepower is listed at a little over 40 at 1530 RPM. For the man that asked about the governor, standard equipment was a Novi governor. Before you go ordereding springs and so forth take it apart and double check if you have the ball type or the weights that pivot. Don't tell me you have an FA-226 and belt drive governor. Then none of this applies. There was no Nebraska test listed and it may not have been tested there. It was rated at a 3-4 plow tractor. Remember it was sold as a farm tractor. All this other stuff like blades, loaders, etc. were never built by Oliver. Questions?

[G Huffman]

I took the clothes line wire that the carburator was linked to the governor with and ran the engine but the governor did not move so I will dissamble it and see what gives.  I also am working on a case terra lift track mounted fork lift with a FA 162 engine.  I lost a rod bearing and flattened the crank.  The junk yard said they had not seen any forklift like it and could not help.  Where can I find a crank?  Anybody know where they used this engine?  It has a hydraulic pump into the timing cover or I would put something else in it.

[John Schwiebert]

First of all I need a forging number off the crank. I have a friend who probably has 10 of them in stock for 162 engines. Now we need the forging number to match. Not all 162 cranks are the same. Questions. My friend is in northern Ohio.

[G Huffman]

I have an old FA162 engine out of a forklift that has a hydraulic pump mounted into the timing cover.  Is this available for other Contenental engines.? It seems like it could solve several problems.

[John Schwiebert]

You asked a question. There were probably more F-model engines used in forklifts than any othere engine. This includes both the 4 & 6 cylinder models. Now different forklift manufactures used different setups with the engine to drive the hydraulics. That is one reason there are so many variations in the timing gear covers, timing gears, camshafts, and yes even crankshafts. Now can you tell me more and where you are going with this line of thinking.

[G Huffman]

My idea was that maby an hydraulic pump might be placed under the governor of my F226 engine to give me live hydraulics.  I expect that many people would be interested in different engines with hydraulic pumps to get live hydraulics in sted of having a PTO,belt or chain driven hydraulic pump.  I have a large homemade log splitter I am trying to hook up to something but with a 6" ram I need volume.
