D2 3J & 5J Data
________________________________________
Specifications;
Machine Serial Number Plates; located on back top left hand of transmission case and on left side of engine block behind starting engine clutch lever.

The following are maximum horsepower at sea level:
Drawbar HP………………..………………25.5
Belt HP………………………………..…..31.5

Engine--four cycle, water cooled: Commercial
Fuel.............................................. ..Diesel fuel
Number of cylinders..............................4
Bore and Stroke..................................3 3/4" x 5"
Piston displacement..............................221 cu. in.
R.P.M. ---governed at full load...............1,525
Piston speed.......................................1,271 F.P.M.
R.P.M. at Maximum drawbar pull
(point of maximum torque).................1,000
N.A.C.C. HP. rating for tax purposes......22.5
Lubrication.....................................Fo rce Feed
Crankshaft:
Number of main bearings.......................5
Diameter of main bearings......................2 3/4"
Total area main bearing surface..............80.3 sq. in.

Starting Method:
Independent, two cylinder, horizontal opposed, 4-cycle gasoline engine, equipped with high tension magneto, down-draft carburetor and flyball governor. Bore 2 3/4-in. Stroke 3-in. 10 H.P. at 3,000 R.P.M. Drive by multiple disc clutch and helical gears to flywheel.

The following are maximum drawbar pulls at sea level and rated engine speed.
Drawbar pull:
First…………………………...................5,690 lbs.
Second............................................ ...3,740 lbs.
Third............................................. ......3,025 lbs.
Fourth............................................ .....2,325 lbs.
Fifth............................................. .......1,490 lbs.
The following calculated values for maximum drawbar pull are based on the observed drawbar pull shown above. When slowed down by overload, "Caterpillar" engines develop a considerably greater turning effort at the flywheel (torque), which results in greater drawbar pull at reduced travel speed:

Drawbar pull, Maximum.
First............................................. ......6,160 lbs.
Second............................................ ..4,050 lbs.
Third............................................. .....3,280 lbs.
Fourth............................................ ....2,520 lbs.
Fifth............................................. ......1,615 lbs.

Second............................................ ...2.5
Third............................................. ......3.0
Fourth............................................ .....3.6
Fifth............................................. .......5.1
Reverse........................................... ....2.1
