[TR] 1976 TR6 air pump rattle

[Bob Danielson]

Dave,
My air pump packed it in about 6 or 8 years ago. The first thing I did was
to do a test run to make sure it was the air pump making the noise. I was
pretty confident seeing as moving the pulley by hand felt and sounded like a
bunch of out of round marbles. Basically I ran the car bypassing the pulley
to see how things sounded. Then I removed the pump and all the hoses and
installed a plug in the EGR fitting. The carbon canister was left in place
and connected. A year ago I finally got around to removing the air rail from
the manifold and plugging it.

This should be a softball for the experts on this list, but I simply don't
know the answer.? While?running the engine in my 1976 TR6, I heard what
sounded like a rattle that I had not noticed before, though it may have been
merrily rattling along for some time.? As I focused on the sound, I believe
that it is coming from the air pump (smog pump?) rather than from the engine
internals.? If this is the problem, and I decide to eliminate the pump, can
I simply remove the belt between the water pump and air pump with no further
action necessary, or should I blank off the connection from the pump?? If I
am going to remove the pump, should I remove all of the pollution controls??
I am in Georgia and the car no longer requires an inspection so that
particular issue will not raise its ugly head.? The car is an occasional
driver, not a daily driver.? Except for a Crane electronic ignition, my car
is very stock with all pollution equipment still in place.? Your advice is
greatly apprec  iated.
