idler pulley bolts?

[BerniniCaCO3]

Hi!

Just wanna double check something here...

The idler pulley on the passenger side, the one that goes with the A/C compressor and the air pump,
It has two bolts: one big fat bolt that holds the idler pulley itself to the swing arm.
A smaller one that holds the point that the swing arm swings from.

I've been assembling absolutely everything from the ground up with a mix of memory, best guesses, some forum posts, some best guesses from friends.

Right now I've got that smaller pinning bolt, the one under the AC compressor, with the head facing out and the bolt threads in towards the passenger's seat.

A nagging memory tells me that I once had to reach behind the ac compressor, that that bolt should actually be threading the other way?
Memory might be nagging me falsely, but better safe than sorry!

Thanks!

Oh, quickly, doesn't really merit a thread... 2-1/4" exhaust pipe, is pipe, just pipe? I only need 2 6" lengths, wondering if I can pick up 2-1/4" steel tubing at home depot rather than seeking out a specialty exhaust place, if 2.25" tubing is tubing and there's nothing too special about "exhaust" tubing.

The head faces the front of the car. There's a bolt that holds the idler pulley in place behind the pulley itself, that's what you're thinking of.

I wouldn't recommend using Home Depot tubing to make an exhaust. I'm pretty sure that exhaust pipe is treated in a way that it can withstand heat better. But I'm not sure. Someone else will chime in here sooner or later... What're you trying to use this pipe for on your exhaust anyway?

"There's a bolt that holds the idler pulley in place behind the pulley itself"
uh-oh... I don't think I have that in place?
The ~1/2" bolt that goes through the center of the idler pulley and holds it to the swing arm, must come through the front, because the arm is tapped to receive it....there's a third bolt?
I do remember having to loosen something from behind, but if it's not the pulley bolt and it's not the pivot bolt, where's the 3rd one go?

Pipe at HD is not well suited for exhaust. It will be either copper, iron, or galvanized iron.

It is thick wall, and heavy, and probably a different diameter. Sometimes trade sizes are nowhere near what they claim to be.

Exhaust tubing has a thinner wall. Sometimes its aluminized, sometimes its not. No special heat treating to speak of. Just mild steel.

once had a buddy make side exit exhuast with a couple of old drive shafts for his vic.

People used to use old torque tubes to make headers as well. Driveshafts usually have a thinner wall than iron pipe anyway.

Click here and scroll down for a pic of the belt diagram. It shows the 2 adjustment bolts (pivot point and back side "clamp in place" bolt). With the bolt on the pulley itself, that would make 3.
