> 6-bladed 'Tropical' Radiator Fan Blade
THe factory parts manual shows two fans available. Early TR4As were
fitted with a metal 6 blade fan and an extension which was attached to
the fan pulley hub by 6 nuts and bolts. The fan was attached to the
extension with 4 bolts.
The drawing shows a fan with the hub arms to which the blades attach
narrowing as they extend. This is different from the one pictured on
ebay. It also shows a larger center hole than is apparent in the
photo. (Drawings are drawings though...)
Later engines were fitted with a different extension which mounted to
the fan pulley hub with 3 nut/bolt pairs . The 4 bladed fan had
plastic blades and attached with a single "disc" and "washer". The fan
had 4 smaller holes (around the larger centre hole) one of which fit
over a dowel which mounted in a single hole in the extension. This is
described as "Dowel, locating fan".
Oh, if Ted is reading all this... your fan is not "very unique" . An
object is either unique or it is not, unique meaning one of a kind. An
article such as this fan, obviously manufactured in great quantity and
used as standard fitment on an automobile is not even rare or unusual.
