Would like to hear your thoughts on installing a vent cap on the hydraulic fill cap on an 801 Ford. Would that just let more condensation in when it cools down. I'm in Florida and it gets pretty humid on some days.

Are you having some kind of issue that makes you think that you need a vent? They didn't have one when they were new, and now, 60 years later, most of them that were not abused are still functioning just fine. Why fix it if it ain't broke?

They all ready have 3 places to vent. Both sides of rockshaft and draft control spring.

I have one that sits outside when its not working. I just pulled the cover off and it has some rust around where the draft spring attachment comes through. I dont know why they didnt seal that better, maybe so it could breathe? I thought i might put a vented fill cap in while its working hard and swap it at the end of the day when it starts cooling down. I got the lift piston moved out with air but when I removed the cylinder it wouldnt budge. I did it easier by pounding the cylinder against a good live oak 2x4.

I have a 9000 that was in the weeds for seven years before I bought it. When I split the transmission from the rear end I found a lot of rust on the outside of the PTO clutch housing, and I could see rust tracks on the underside of the top of the rear housing where the condensation ran along down slope to a low point in the center where it dripped off the roof and onto the PTO. Unless you can keep your tractors in climate controlled space, air will be going in and out and carrying moisture in with it. These cases MUST BREATHE! This is why cases have vents. If the changes in pressure can't equalize seals would get wrecked and dust would be getting in.

I know the heats gonna come and go but I know you can have a tire that leaks air very slowly but fill it with water and it will run a long time. Water wont go through tight spaces. It will get sucked into something if it rains on it and cools it down quick.

The water in vapor form goes in and out with the air. You always have some water vapor inside all of the housings of every piece of machinery or vehicle that you have. When it gets cool enough the water vapor condenses into water, or if below freezing into frost. When you use the piece of equipment it gets hot and the water turns back into vapor and comes to equilibrium with the surrounding atmosphere.
