The Crusty Cuda: Whole lotta Shakin' (N96) Goin' on!

[njsteve]

Spent the day under the car. Adjusting the parking brake so it works now.

Then I pulled the driveshaft and removed both u-joints in preparation for cleaning. I also ordered a couple more gallons of Evaporust and dug out the giant PVC pipe that is just larger than the diameter of the driveshaft. This way I can slide the driveshaft in and then fill it with evaporust and let it do its magic. Here's the driveshaft sitting next to the patent-pending Deluxe Driveshaft Derusting Device, along with my trusty 1989 John Deere 185, that I bought used as a dealer demonstrator in 1990.

I also installed the shaker baseplate seal which is quite an entertaining fete. it comes as a straight (but rolled up) section of extruded rubber that you have to glue the ends together and then tape them, like the factory did. Got that on and then installed the 50 year old original shaker drain hoses I had off my of hemi ragtop. The factory used the ribbed heater hoses for this application. They were just slightly more pliable than volcanic rock, but installed fine. They still had their original bends petrified into them, that were there in order to clear the alternator bracket and to steer away from the battery tray.

And look what I found in the garage...some vintage Day 2 parts. Kraco 6-9 speakers and an FM converter. I checked the speakers against the screw holes that are already in the rear deck and they matched up perfectly. I can hang the speakers under the deck with some small screws and nuts and it won't affect the package tray at all.

After soaking overnight in the magic derusting cylinder, here are the results at the moment. Just an interesting note: the small pool heater I had hanging in the fluid at the top of the cylinder resulted in better derusting results on the end of the driveshaft that was closest to the heat source. So that is today's lesson: the warmer it is, the faster it works. This is an old gallon I have been using - and it more than filled the space needed to fully submerge the driveshaft...oh an BTW, driveshafts float, so I used the yoke to weigh it down enough to keep it fully submerged.

The mud colored water in the blue bucket is the runoff resulting after I scrubbed the driveshaft with a brush. That's another tip: frequently remove the object from the liquid and scrub it down to get the derusted residue off the surface and allow the liquid easier access to the metal.

P.S. don't dip certain plated items in the liquid - it will dissolve the plating. Not so much with chrome, but it removes blueing, black oxide, cad plating, zinc, galvanizing,. It will also attack pot-metal pieces. If it is plain old iron/steel (and grease-free), it works like magic.

I will pick up some more (fresher) evaporust tomorrow. After a while, the solution absorbs so much iron that it reduces its effectiveness drastically. It should be amber colored. If it is dark or black, it is no longer going to do much good.

More progress a day later. I bought two gallons of evaporust today at the local advance auto. And lo and behold one of them was filled with water. So I am returning that one tomorrow. Nice!

So I dumped out the old used up evaporust and scrubbed the driveshaft again and replaced it back in the tube with the one real gallon I bought.

Here's how they looked today:

And day 3 after an overnight with a fresh gallon. Now that's some progress as compared to the old stuff.

Looks great. Amazing stuff.
