18. The ETPC will allow component tractors in the super stock class under the

following criteria:

a. Must install an one-piece frame extending from front of tractor to rear axle housing

with an ETPC approved bellhousing (chapter 2 point D) to replace the original clutch

housing. Must also install an aftermarket transmission and rear end to replace the

original equipment transmission and rear end/final drive housing. No cast iron

agriculture type transmission or rear end component allowed.

b. Drawbar and roll-cage must be part of the frame structure.

c. Engine block of given brand to remain consistent with that brand sheet metal.

d. Engine location of component super stock tractors: centerline of the crankshaft may

be below the centerline of rear wheels but must be parallel to the ground +/- 2

degrees. From centerline of rear wheels to center height of front of crankshaft max.

drop of 75 mm.

Frame must be parallel to the ground +/- 2 degrees. This equals approximately

100 mm of fall from centerline of rear wheels to the 2900 mm wheelbase point. This to

be measured with tyres, hitch and weight in ready-to-pull position.

e. All engines in component super stock tractors to be mounted no farther forward than

1524 mm (60 inch) measured from the centerline of the rear axle to rear of the engine

block.

f. Crankshaft centerline to be between top and bottom main rail of frame.

Bottom of main rail maybe no more than 150 mm. below centerline of crankshaft from

rear of engine to front axle.

g. All tube ladder-type frames must be covered on the outside with steel or aluminum

2 mm thick and run in the same plane as the crankshaft.

h. Appearance to remain stock of given brand and model.

i. Driveline shielding same as in Modified tractor rules.

j. All component tractors can run a maximum of 2900 mm wheel base, with a maximum

overall length of 4000 mm from center of rear wheel to forward- most point.

k. The constructions of all component tractors must be pre-approved by national tech

inspectors. All dimensions must be measured and, together with pictures, be on a file

and signed before the vehicle is allowed to compete. This file has to stay with the

tractor and it must be shown upon Tech Inspector’s request.

B. Frame/sheet metal

1. Tractor must have hood and grill in place as intended by the manufacturer.

2. It is allowed to update the sheet metal of a super stock tractor to the latest model made

by the manufacturer as long as that body is still in the program.

3. Sheet metal to be stock length and in stock location.

4. Tractor must retain stock appearance

5. The distance from the center of the rear axle to that part of the hood that is farthest

forward must be the same length as that model of the upgraded sheetmetal.

6. Wheelbase rule will apply according to the original chassis, not to the model of the

upgraded sheet metal.

7. Maximum of 2900 mm wheelbase unless originally produced with longer wheelbase, in

which case stock length must remain. Maximum length of 4000 mm from center of rear

wheel to forwardmost point including weights and weight racks.

8. Super stock chassis rules A: 1-10 above will apply according to the original chassis, not
