Knocking things off the to-do list...
Here's the ongoing, but fairly straightforward development of the accessory drive bracket:
I'm relocating the idler pulley slightly
And will be popping the tensioner in up here, but not at this angle
I schwacked the power steering pump bracket from this:
Down to this:
And here's how it fits:
And the engine with these small things on the front:
I also pulled off the oil filter adapter... again... and re-re-re-re-tapped the oil pressure sender/switch port to make sure it is straight and the correct depth to keep the fitting tight to the adapter. As noted above, I need to figure out a fitting tree to get the oil pressure transducer installed, but that shouldn't be too bad.
I'd never used a tap guide before, but it worked and with results that surprised me. I guess it's a tool on the market because it works. My dad's tools don't always work, though.
I turned the tap liiiiiiiterally 1 revolution at a time in between test fits of the reducer elbow fitting w/ Aurora oil pressure sender. I worked it down to the depth I thought was good and thought I'd done a good job. I had been noticing that it seemed to take a lot of angular movement beyond hand tight in order to get the reducer elbow to tighten up. I was putting the tap away in the box I got it from and noticed it was labeled 3/8-18 NPSF.
S?
S?!? Oh GDMF F@#$% sunnova... :bad:
I snagged the correct NP
TF tap, ran it in ONE more revolution and re-installed the fitting. There's exactly ONE thread of the fitting still out of the boss. I had to remove the oil pressure sender in order to run the reducer elbow all the way in, since it was so close that the sender hit a feature on the filter adapter. It tightened up enough that it should seal just fine, and it snug, square and straight, so I'm done with it... especially since doing anything else would require buying a new filter adapter from GM. If I can't get this joint to seal, then I'll think about that. It's good enough to get the engine running and wheels turning.
