GEARBOX TOP COVER ASSEMBLIES
TOP COVER ASSEMBLIES
(There were a number of
different part numbers for the top covers fitted to the
TR6 range of gearboxes, each part number indicating
some variation in the design of the component in question,
and the factory literature is extremely vague about when
changes were made. We shall tell you what we know about
each one as we list it below, but it should be noted that a
great deal of what we say is based upon educated guesses,
as very few part numbers are currently available from the
factory for examination. However, TRF can supply top cover
assemblies made up out of new components to any of the
specifications given below.
