1990 Throttle hesistation

[Schrade]

But wait - it's gets better.

Plenum off. Maybe it dropped under there, or even UNDER the A/C comp. It has to come off anyway, because the lower TB bolt bailed, between the A/C comp, and the alternator.

Let's lift the A/C comp. Nope - the forward inboard A/C comp bolt is too recessed under alternator to get the 10mm socket on it - slipped once. 10mm box slipped too. Pull the alternator, BEFORE we round off the 10mm hex, to something that will load in a 9mm shell casing.

Then the alt field output nut seized on the bolt, and the bolt turned in the case. Di-electric grease glue??? WTH? Needle-nosed pliers on the output wire ring, 10mm on the nut.

The wire ring broke. MF'er.

Now - is the alternator toast, with the field output INTERNAL bolt connection broken?

Can of worms? Hardly. You can only get so many worms in a can. How many worms can you get in an LT5?

I'll let your great grand-kids know.

You are not even close to how bad it can get. I had to pull the engine and replace a liner/piston/rings

You know if I've detonated my alternator here Cliff? The field output bolt turned about 1/3 counter-clockwise.

It it a wire connection internal? Or washer-type?

I think a bench test at Advance in the AM is in order...

Anyway, no TB extension bolt under the plenum....................................

Split the case and check or simply have the alternator tested at Oreillys or Advance for free.
I doubt you destroyed the alternator beyond your own repair.....

That is why I suggested to split the case and when at it you could check brushes and bearings......and check/reinstall that connection from inside the case.

Watch the brushes when you pull out the armature very slowly......Something like this as this is typical.

After you had already done it once, and were putting in the last bolt?

I was DONE, except for DataMaster analysis.

Now the plenum is off, A/C comp loose, coolant lines out, alternator out, broken ring on the alt. field output wire, scratches in the new painted parts, the TB extension bolt is in the Twilight Zone, and after I find it, and get everything put BACK together AGAIN, then back to DM, to try to solve the hesitation.

But life is good. The alternator bench tested good. Kinda' bothers me tho' - I KNEW i was gonna' have to repair it, or buy another alternator...

It ain't as much fun as it was last week.

Chuck,

Have you seen any wild geese lately?

Funny guy, huh...

I'm gonna' have the cleanest machine of all, that doesn't work right...

I might make BG ... in '15 - 2115 - and then again ...

Change of heart; time to admit defeat.

Quittin' time. Tomorrow, put a box to the crank pulley bolt, and spin it. If it doesn't grind out the bolt from behind the pulley, put it back together, and try to find a replacement TB extension bolt. Then drop IT too.

This crap is makin' me sick...

I know exactly what you are thinking......but down under around motor mounts are lots of hiding places
I am sure Jerry has exactly the bolt you are looking for.
Just type in Throttle Body in the Search and look at third page of that search on Jerry's Web Site

Got it; thanks there Cliff...

This kind of thing eats me up tho'... I could find and solve the 'hesitation' gig, but knowing that my bolt is under the motor will never stop bothering me. Never. Even if I knew it wouldn't roll into the serp belt (which I now know), and mangle a pulley, it wouldn't stop bothering me...

Jerry; if you're watchin' here, send me this TB extension [upper] bolt. I'll forward PP, or CC#, or check.
