Fan shroud with integral hood seal
A one piece fan shroud for a tractor has first and second faces, a frame with top, left and right sides, a bottom, and an upper wall extending from the top of the frame. The upper wall, left and right sides of the fan shroud are dimensioned to match the internal geometry and seal with an internal surface of a tractor hood. A rubber seal may extend around the upper wall and the left and right sides of the frame.
1. An apparatus comprising:
a radiator on a front of a tractor frame;
a tractor hood attached to the front of the tractor frame and having internal top, left and right sides; and
a one piece fan shroud attached to the radiator, the one piece fan shroud having an uppermost peripheral wall portion sloped at an angle of between about 10 degrees and about 60 degrees from vertical to form a seal with the internal top, a combustion air intake opening through the sloped uppermost peripheral wall portion with flanges projecting outwardly from the opening for connection of combustion air intake ducts thereto, and the one piece fan shroud further having generally vertical aligned sides that seal with the left and right sides of the tractor hood.
2. The apparatus of claim 1 wherein the one piece fan shroud has a rubber seal around the uppermost peripheral wall portion and the generally vertical aligned sides thereof.
3. The apparatus of claim 2 wherein the rubber seal is a bulb seal.
4. The apparatus of claim 1 further comprising a ledge around the internal top, left and right sides of the hood.
5. An apparatus comprising:
a radiator assembly having a generally vertically oriented radiator with a one piece molded fan shroud mounted thereto; the one piece molded fan shroud having a rubber seal around three outer surfaces thereof; one of the three outer surfaces extending at an angle of between about 10 degrees and about 60 degrees from vertical at an outermost peripheral portion thereof and having a combustion air intake opening extending through the angled outermost peripheral portion with hose connection flanges projecting outwardly therefrom; wherein the radiator assembly is mounted on the frame on the front end of a tractor having a hinged hood, the rubber seal mating with the internal surfaces of the hinged hood.
