TRACTORS

FARMALL CUB
The Farmall Cub was a tractor for small acreages and for
truck and vegetable farms. It remained in the lineup from 1947
to 1964. This was further vetific~tion of the demand for a
small tractor. As rotary mowers became popular, many Cub
tractors were equipped with the underslung mower. The Cub was
marketed to parks, cemeteries, large estates, municipalities
and to small farms.
International used their own valve-in-head'four cylinder
engine of 59 CID. It was the smallest tractor made by the
company with only a 2 5/8 by 2 3/4 inch bore and stroke. The
engine speed was rated at 1600 RPM. The tractor weighed about
1,480 lbs. and recorded 8.8 HP on the drawbar. A three speed
transmission of 2.1, 3.1, and 6.4 MPH was standard equipment.
A tire size of 6-24 for the rear and 4-12 for the front further
denoted the smallness of the Cub. The tractor was equipped with
an adjustable wide front. The advertising listed more than
a dozen implements that were available and designed for the
tractor. Fuel economy of the Cub was 8.6 HP hours per gallon
of gasoline.
An improved model of the Farmall Cub was tested in 1956
and recorded about 10 HP on the drawbar. other major differences
were engine speed increased to 1800 RPM, tire size increased
to 8-24 on the rear wheels' (the front remained the same), and
transmission speeds increased to 2.4, 3.2 and 7.3 MPH.
Fuel economy was 8.5 HP hours per gallon, which was slightly
less than the Cub model tested nine years earlier.
During the period 1947 through 1958 International was to
market more than 225,000 Farmall Cub Tractors. Over 47,000
were sold in 1948, the peak year of production.

Reassembly
1. Coat the valve stems with engine oil and insert the intake and exhaust valves into their original positions.
2. Install the valve springs and valve spring seats. Compress the valve springs and install the valve seat retainer keys. Release the springs and remove the valve compressor.
3. Adjust the valve tappets. Refer to page 1-15.
4. Install the valve tappet cover using a new gasket.
5. Install the intake and exhaust manifold assembly using a new gasket. Tighten the nuts evenly in steps to 20 ft. lbs. torque.
6. Install the cylinder head. Refer to page 1-14.
7. Refill the radiator with coolant.

Connecting Rods
The connecting rods serve as the links between the pistons and the crankshaft. The surfaces of the rods must be kept free of scoring and dents because of the high stresses under which they function. The rod has a bushing at each end, the one at the upper end is a bushing for the piston pin which anchors it to the piston. The bearing at the crankshaft or lower end is inserted in two halves which fit around the crankshaft and are secured by a bearing cap. The bearing cap is furnished only with its connecting rod.
The lower bearings used in these engines are the replaceable insert type and insure correct rulming clearances when they are properly installed. This is possible without boring, reaming, scraping or using shims. The three important fundamentals on bearings and bearing fitting are "bearing crush," ''bearing spread," and ''bearing clearance." An explanation of these will be covered later.
