This is an absolute necessity if you are rebuilding your engine or if your
damper looks anything at all like this after all of the grease is cleaned off of it.

Once the rubber isolator becomes too contaminated with oil and begins
to break down and crack, the outer grooved pulley can actually move on the
inner section that fits over the crankshaft and that makes timing the engine
to specs a barrel of laughs.   Have you ever heard the following?

Why don't I have any power?  It's set at 12BTDC

I know the timing is right, but why won't it shut off when I turn the key off?

There can be a lot of reasons for those two questions,
but a slipped damper condition may very well be one of them.

After searching the internet for a company that would do  Triumph damper
(and they're aren't many!) I came across Damper Dudes in Anderson California. 
I called and spoke to Gary and he was very knowledgeable as well as positive
about doing the TR6 damper.  He has done a lot of them, but had none left on stock.

So what you'll see below will be the before and after along with the
fan eliminator bolt kit that I bought.  This save an additional nine (9) lbs.
from the end of the crankshaft and when coupled with an Aluminum
Radiator, the cooling and weight savings is well worth it.
