One my last few junkyard runs in Slumkane, WA found perhaps the newest version of the Bosch Volvo 240 LH-Jet 2.4 AMM 0280212016.

I have a half-dozen or so, I guess, of these 016 AMMs.

This one appears to have the newest innards with the beefy heat sink and the Y-thingy with the thin 'blade' across it upstream of the actual wire. My small collection represents three distinct design variations inside the wind tunnel part of the AMM.

Where you secure an AMM to the bracket, I found the bolt driven through the bottom of the boss(?) or well. That small anodized sleeve that resides inside the rubber cushion was missing.

I mean to remove the rear screen, remove the plastic piece dislodged from the puncture, and use emery paper to rough it up inside and press the adhesive inside the well (or boss?) bottom, yet not above where the securing bolt would reside had the sleeve been there to prevent this from happening when some unknown PacNW denizen did this.

How would you repair this?

I don't want chunks dislodging inside the thing. Yet want to try this newest one, of hopefully not fried from the hot side open flap valve on the 240 I removed it from.

I also mean to try some of the CRC MAF Sensor Cleaner spray on this and the other two AMM as I replace the three air filters.

Of course I'll test the voltages as I put everything back together. The 1991 uses the same AMM that came with it when I bought it in June 2000. Or maybe not. I forget.

Thanks. Enjoy the images.
