Detail of a Class 120 DMU

Details

An official image (19 of 27) from a internal BR photo album titled "Part Refurbished Class 120 Prototype 1 and 'CIBA Giegy' Ceiling".

This shows the short cardan shaft that joins the 'right-angle drive' on the rear of and driven by the engine to the fan on the radiator. The cup section at the fan end seems to be a revised arrangement with a rubber mount to reduce vibration and preventing the wear of the fan bearing that would produce a distinctive rattle noise. The castellated nuts on the fan are wired together in pairs, sometimes each would have a split pin instead.

All the images in the album so far have been of W50674, but this (two of four) does not have a negative number where the others do, so could be a generic image taken elsewhere.
