Noisey engine accessories?

[andymac0035]

Well I went out to the parts car......the smog-pump-swap idea is out. (it was completely frozen-up)

So now I can:

-Do nothing......

-start removing the smog system.

-Put the belt back on and wait for it to get so bad I'll easily be able to figure out which pulley is squeeling.

-get a short belt for just the A/C as it does still work

I don't suppose anyone wants to post an engine bay shot with the offending smog pump circled? It sounds like taking mine out might be a good idea..

I can't circle it for you.......but it's down and to the left of my new waterpump in this pic and the pulley is off of it.

I circled it:

Interestingly......I seem to be a bit too cautious about overtighteng things lately.
My car started to get noisey again, even with the A/C belt off. The bolts that hold the fan to my (new) water pump had backed off. I put the belt back on today, no noise.....but not that cold today, we'll see what tomorrow brings.

[andymac0035]

I still have the same noise (the fan noise was different).
Ahhh well I was hoping....I still have the belt on there as I like having the A/C compressor hooked up for faster defrosts.

It's still looking like it's the smog pump. I can actually hear the noise coming from under the car with the door open and since that accessory is mounted low on the engine, that makes sense.

The thing that gets me is it sounds like a worn out electric motor squeeling away more than a bearing.

That squealing noise from electric motors? Thats the bearings in the motor dying. Actually many small motors have a powdered bronze bushing that is soaked with oil instead of a roller bearing. When the oil dries up, it carries on like that. I suspect the smog pump has those same type of bushings. You can actually re-oil them if you want to spend too much time on it. Press the bushings out and cook them with a torch. Once the oil is burned out, put the bushings in a jar with oil and figure a way to pull vacuum on the jar to purge the air out. Or, you heat the bushings in oil gently until the air comes out of the bushing.

Totally not worth the effort, but if you enjoy wasting time on such things you can do it.

[andymac0035]

I don't see myself doing all that.........
I was looking at bypassing it all together and it looks like I would need to remove the smog pump to run a short belt to the A/C? I still need to check with a few inspection stations to see if they care about that (I don't think they do).

It all seems to make perfect sense.....the way you decribed to me (earlier) about how and when the smog pump cycles... and that seems to match up to when it's noisiest. It's stickly a cold-weather thing so far....it was warm today so things stayed qiuet.

[gadget73]

yeah, short belt and bypass the POS. I forget if its a 500K6 or the 560K6. One is the stock alternator belt, the other is the smog pump bypass belt. I think its the 560. If its an inspection issue, just bypass it until its inspection time, switch belts for testing, then switch back. If the belt hits the smog pump, the smog pulley is held on with 3 small bolts and then you can just pull the thing off.

560k6 is the smog pump bypass belt

[andymac0035]

Thanks mangs

Yeah, I had to take that pulley off when I changed my waterpump. I was just looking at things and thinking that the smog pulley might hit if I tried to bypass it.....that's why I asked.

Do I need to plug any lines? Or is that just if I remove it al-together?
(I've been watching that other thread on this subject)(but they were pulling the pump)

Thanks again.

[gadget73]

If you leave it physically there, you don't have to cap anything off. The important thing is to just make sure there are no vacuum lines hanging in space. As long as they're connected to something, its not a leak and not a problem.

[1990LTD]

Can I keep the belt that's on there if I'm just bypassing the smog pump? I'll take off the pulley or whatever else gets in the way, but since I don't want to go disconnecting and capping any lines, I'm gonna leave the pump there. Not hurting anything if it's not spinning.

[andymac0035]

I do believe Scott and Thain are saying we need a shorter (size 560K6) belt.

[1990LTD]

I don't know why I read it that way the first time. No sleep will do that I guess

What does the smog pump share the belt with? How many friggin' belts are down there, anyway?
