Installing TPS sensor in 00 front rim
I finally got around to putting together my "Teats-on-a-bull" HarborFreight manual tire changer.
After I finally got the old tire off I tried installing the TPS and discovered that the way it was supplied would not work.
Normal tire valves have a bulb with a notch cut out, one pulls the bulb through the rim from the inside out--the bulb snaps into place.
with the TPS thers isn't a bulb, a rubber gasket on the TPS that fits into the recess inside the rim and straight shaft that supports the small shaft to attach the chuck to install air. the TPS is supplied with a nut that is thinner than normal for a bolt of that diameter.
when I clamped the nut down as far as it would go into the recess on the outside of the rim, it wasn't enough to solidly seal the TPS.
since I'm from New England, and its Yankee tradition to NEVER throw anything away that might be possible used in the future, I started poking around, no suitable washers, but I did find some rubber washes that needed to be trimmed. It might have been since it was past later at night into early morning that I tried trimming one down into a circle that would fit the recess, but to do so, I had to also trim the inside of the washer to slid over the TPS shaft. Trimming the inside was maddening as was trying to get a circle for the OD. I just held the nut against the washer, took a single edge razor and cut it down to the size of the nut and was able to push/thread the washer over the TPS.
Trying to do the same with the TPS in the rim with limited access around the TPS shaft......I gave up and went to bed.
Next day I was poking around some more and spied little crush washers for the brake line fittings. One easily slid over the TPS shaft and looked just wide enough to catch the rim. One wasn't enough so I looked for another and spied a bag I have of extra crush washers for when I change all fluids. i poked around with them and found some a little larger than the brake line ones and smaller than the ones for FD, trany, etc.
Perfect size and height when I used two of them that allowed enough threads above the shaft for the nut to grab a hold of and tighten down so that everything is solid.
