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.

**** Viewers are warned that if they attempt any mechanical repairs or modifications,
or follow procedures referred to here, they do so at their own risk, and no liability will
attach to either myself, Damper Dudes or Her Majesty's Service, Inc.****

This is an eBay original damper.  It took a lot of degreasing to get it to this condition.


You can see that the cracks have begun and the rubber is breaking down.

We'll fix this hard to read condition as well.

This shows just how deep the cracks can go.  Oil and rubber like this don't get along
after a lot of years and the accumulated stress of the damper doing it's job hurts too.

This was never going to be installed on my new engine in this condition.

So Gary says that it will be turned around in 24-48 hours.  I said OK.......we'll see.

Guess what?  He did turn it around in 30 hours after receipt of part and out the door.

A beautiful new bright red paint job after some additional
blasting at Damper Dudes and it's ready for the white paint in the grooves. 

I did put three coats of clear over the white after it had dried for several days

The seven (7) drilled indentations across the face are from
the complete engine balancing at Mason Machine. 

This is the fan eliminator kit to replace the shaft and fan blade.

You can see these marks when the timing light beam hits them

The eliminator in it's correct position.

And in place on the newly rebuilt engine.

All lined up and waiting for the radiator to be installed.

Thanks Gary!
