Oldsmobile mystery washer???????? HELP!!!!

[69hurstolds]

C'mon dude, we need measurements down to the micron. Preferably in both metric and standard. Oh, and thickness. That washer looks bent like it was over-touqued. Did you youse touque it? Did you use a Craftsman model 1019 Laboratory edition, signature series torque wrench. The kind used by Cal Tech High Energy physicists, and NASA engineers. And how do you know that was accurate? Because a split second before the torque wrench was applied to the bolt holding that washer, it had been calibrated by top members of the state and federal Departments of Weights and Measures, to be dead-on balls accurate.

Dead-on balls accurate?

It's an industry term.

I see what you did there.

The side rear washer to the block for the power steering bracket is thicker than the one shown as I remember. Can't say for sure, but that looks like the washer that goes behind the adjustment bolt for the power steering if it indeed is coming off the front of the engine in that area. That's my guess. If it's for a 7/16" bolt size that's where my money goes.

As said, there is an actual spacer that goes behind the bracket, probably the washer for that bolt. I love the Olds V8 but it's whole belt set up with spacers everywhere is frustrating at times, especially if it has been apart for any amount of time.

I have the full to the point answer that everone will agree, it's an extra part that is ment to be found after the work is done. We all know here are extras left over after any work on any motor vehicle.

Looks like it's been beat up by something scratching on it going around and around...like a lock washer. If it were used as a spacer I would guess it wouldn't be pulled in in the area near the center nor scractched up like a vinyl record. That's why I say it's under the head of the adjusting bolt. And I'm sticking with that. IIRC, that's the only 7/16" bolt that uses a flat washer and a lock washer on top of that. The spacer washer would be between the pump side and bracket and likely not scratched up like that. The bottom bracket bolt only used a lock washer under the bolt head- but pulling that from memory the last time I performed maintenance on the jacked up mounting system. You'd think after 20 years they'd make the brackets the correct size to the pump.

Turna, did you check the size yet?

Yup, they're engineered with 20% extra parts!

Glad you found one. It's kinda tough to find new.
