Greetings Brains Trust.
I have in my possession a spare 2CV gearbox which I had stashed away (in a dismantled state) in what I thought was a well protected spot.
When I recently delved deeply into the storage area I discovered to my horror that water had weaseled its evil way into the empty casing and eaten away at the insides somewhat.
I have a friend in the Mini community who is a gun with his hydroblast machine so, since I was getting a Mini gearbox casing treated by him, I also got him to have a crack at the 2CV casing and see how it came up. The outside is lovely and shiny, but, where the water was sitting inside, there is a lot of pitting. None of the pits are deep enough to go through and allow egress of the oily substances, but they are of some concern.
In discussion with him, we wondered if there may be a product of some kind that I could use to treat the surface, possibly filling the pitting. If there is, and it's successful,. he would like to try it on a couple of vintage gearbox casings that have somewhat suffered over the years.
My thought is that some kind of self leveling epoxy would maybe do the trick, but obviously whatever gets used must also be impervious to oil.
Anyone have any thoughts or experiences in this area? I believe there are treatments for fuel tanks which may even do the job?
I don't really want to re-use this casing in it's pocked form, but since such things are hens teeth in Oz I may have no choice down the track.
Piccies will follow when I take them, but the priority at present is building a new gearbox for the Mini. (The one in it currently is behaving like a teenager, whiny and grumbly! )
So, over to you. The conundrum of the week!
Cheers, Pottsy. (Oh, and happy Star Wars Day for tomorrow!)
