A few days ago there was a thread about sound insulation for the timing chain
cover on a TR3. I checked the timing covers that I have laying around and
the insulation was either removed or was never on. I am trying to restore my
car as original as possible, so I have a few questions on this subject.
1. Was this used on all models, mine is a 59 TR3A TS 58399?
A> Any unrestored Triumph had this, including all the Herald, Spitfire,
2000 and TR range
2. What color is the insulation, and is it painted over?
A> When chipped out and looking at it in section it is a creamy colour. I
guess it was painted over, it is usually so mucky in that area it is hard
to tell.
3. How thick and how uniform should it be applied?
A> It filled the recess of the timing cover and a little more, perhaps
1/4", if you want to replicate the original, put on a blindfold, drink a
dozen cans of strong import beer, spin around on the spot for 5 minutes,
you are then ready to apply the stuff with a trowel
4. Does it cover the whole face of the timing chain cover, or just a
localized area?
A> Just the recessed area.
Hope this helps.
