Help with smog pump hitting the timing belt

[howierodgers]

Hi everyone.
Unfortunately I’m California I have to keep my smog in tact for an emissions test but I’m having an issue with the smog pump just barely touching the timing belt causing it to rub a little. Don’t want to risk shredding the belt obviously but I’m wondering if anyone else has had this problem? Is there a different place I can mount the stupid thing where it won’t be dangerous for the engine?
Thanks in advance.

How is your smog pump currently configured? Is it mounted near the exhaust cam pulley and driven from a small belt off of that pulley, or is it mounted down below and driven with a belt from the crankshaft pulley? On the driver or passenger side?

Hmm. On a '79, it is on passenger side, low, runs off a small belt off the crank. Mine is in front of the timing cover. don't know how it could rub on the timing belt. Of course mine is off completely except for 1-2 days every 2 years for what I call "smog weekend".

It’s currently running on the small belt off the exhaust cam. I’ll go out and snap a pic for you.

Hmmmm.... I thought the smog pumps that were driven off the exhaust cam pulley were in the mid 1970s, but by 1979 or 1980 or so the smog pumps were lower down and driven by a belt on the crankshaft pulley? Is it possible that your engine has been modified/changed?

At any rate, a picture would help. Or a description of what exactly is hitting the timing belt. A hose, the body of the smog pump, a bracket, pump valve, etc.

The link above is a photo I snapped of the pump where the belt is touching it. Should I relocate this thing to run on the crankshaft pulley?

Does it actually touch, or it's just really close?

You could move the pump, but that might require a new crankshaft pulley, brackets, etc. Plus, and the main thing I would worry about, is that the smog test technician would say, "Hey, your smog pump isn't where it's supposed to be! This engine has been modified and thus we won't pass it."

But, it would be interesting to find out if that location is where the smog pump should be for your model year. As I noted earlier, I thought smog pumps that ran off the exhaust cam pulley were only used up until the mid to late 70s. I'm no expert on this, of course...
