[TR] TR4A Radiator Duct

[P Caffrey]

Hi Alan,
Thank you for the reply.  The 4A radiator duct, from what I've heard
through my inquiry on the List, appears to be a different design relative to
the TR4.  Also, the 4A duct is apparently hard to find though I'm still
searching.  I'm checking with TRF and Triumphs Only for availability of this
duct.  I believe Moss only has the TR4 version....I may have to make an
aluminum/plastic duct as you did.
Thanks again,
Pat

Re: [TR] TR4A Radiator Duct

Hi Pat,



That looks quite similar to the duct
that came with my '62 TR4. It was "fibreboard", aka cardboard or chipboard and
exactly that shape and size, as best I can tell from the photos. The only
difference, the one in my car had a black finish on the "top" side seen in
your?photos.?It?appeared to be a layer of black paper. Inside it was more
brown than gray. I bought my car in the late 1970s and would guess the duct
was original (it still had the original gearbox cover, which was similar
material). 



The fibreboard in my car was in bad shape. I reinforced it on
the inside with fiberglass cloth and soaked it with resin (did the same with
the gearbox cover). It lasted another ten years or so, after which I finally
replaced it with a homemade?aluminum duct. I've seen replacement ducts (and
gearbox covers)?made of black plastic, too.



I don't know if the TR4A used
exactly the same duct as the TR4 (or the TR250/5, for that matter). I know the
radiator itself is different (mine is the "long neck" same as was used in the
TR3A). 



Perhaps one of Bill Piggott's books shows the radiator ducts.

Hi List,
Checked on my TR4A restoration at the garage
today and noticed a new
radiator duct.  Does anyone see anything wrong about
the radiator duct pic on
the link below?  It seems small to me, as though it
belongs on another
car--other than a TR4A.  
Thanks for any feedback,
Pat
