Tim,

The input shaft and the cluster gear are the only 2 things in the trans that are always moving under your scenarios, I believe.

I would jack up the rear wheels, put the axle on non Harbor Freight stands, maybe take the wheels off, get your least favorite person to lie under the car and
run thru the gears and see if you can isolate the noise.

I used to have 3 transmission shops and we hated manuals with a passion.

Tim,

You definitely are taking a very technical approach, which I think is fascinating.

Does the noise go away if you are moving, put the car in neutral and let out the clutch?

I just tried a product called Acid Magic

I had a part that didn't respond well to Evapo-rust so I put it in a bag with this Acid Magic at 140 degrees and it was derusted in a couple hours with the UC on 30 min cycles every hour or so.

Big Kev,

Thanks for the filter idea. I bought my wife a wonderful chinois strainer she never uses. Maybe it has found a new use.

I am trying to wear out my ultrasonic cleaner. Where has this been all my life.

The question came up if you could use something like Evapo-Rust in it.

Since my tank would take like $75 to fill and it loses its efficiency over time I came up with a trial solution. Also I didn’t want to dilute or have to remove my normal cleaning solution

I had my kick shackle apart and decided to use the dogbone as a trial.

I turned the heat up to 140 degrees, put the part in a ziploc bag, covered it with clean Evapo-Rust, sealed it, put it in the tank and turned it on.

I ran it thru 4-5 30 minute cycles for about a day and here is what it looked like verses the rest of the kick shackle.

It looks like I should have left it in a little longer, but the part came out very clean, unlike the slime you have to wash off on straight E-R soaked parts. So it would appear the UC waves with penetrate the bag and activate the solution in it.

I took the used solution and dumped it into a bucket so I can derust parts that won’t fit into the cleaner until the E-R efficiency is used up.

Big Kev,

I might try the heat cycle on the UC then turn on the cleaner after a day or so.

Thanks

Bill

David,

Due to the slowness of the Evapo rust, it might be better to soak in it for the prescribed time then pop it in to the UC.

I have a current trial in process and I will report on it.

Thanks

Bill
