Fuel Consumption of D9 18A

The d9 serie 18a fuel tank is 157 gals. and should take 10 to 12 gals.
each hour comsomation

That's better than I thought. Anyone concur?

Thanks for the help.

I don't know about an 18 A but a 66A (G) holds 200 gallons and you could go thorugh the tank in an 8 hour shift if you really worked her. That, my Father told me, was doing a full day's work. It ws my right of passage!

Well, the history of these critters is that they did a lot of scraper work and they even have a big, Big, BIG, 4 foot plow to pull behind one. They used the plow to bury sand after the Missouri River had flooded. Only used it for one job that I heard of. They might be used to working the old girl real hard. Thus I might have remembered higher fuel consumption.

Thanks for the info.

Hi Team,
here is a scan from the Caterpillar booklet "Earthmoving Guide To Profit", Fourth Edition, Form No 717-31397.
The scan covers machines by HP Rating for approximate GPH in stated working conditions.
Copy this scan for future reference before it is removed as it is applicable to all machines of the era, and possibly before, as a guide.
The 18A-19A D9 is rated at the engine flywheel as being 286 HP and has a 157 US Gal tank as standard.
To find the GPH of other machines you first need to know the Flywheel HP of the unit to apply to the chart. I have highlighted the D9 with a red line.
Hope this helps.
Cheers,
Eddie B.

I think Leo's tractor is a high horsepower tractor. I have seen pictures of tractors with single and dual air intakes. Leo's has dual intakes. And I think he said it is 325 HP. That puts it a little over the maximum shown on the chart. But I still wonder if clearing land is light work for a tractor.

It's been a very long time since the D9 has been started. It has a bad starter pinion for the pony. One of the things that worries me is that the intake and exhaust are uncovered. That makes me think the D9 is available. It's been probably 20 years since the family has done any real heavy excavation and land work. They have a 943 and are scrupulous about keeping the exhaust covered on that.

I was Looking at a D9 18A (that needed repair) to build a road with the current owner used it to clear land of big tree stumps, I think he said that for the amount of work the machine could do it was cheaper per acre than a D 7
If you want I could probably get you his phone number
I found engine parts to be very pricey for these machines
