disc brakes - super h

How do I prevent the water from getting in? No oil leaks, so do I really need to replace the oil seal? Also, if no oil leaks, can I assume no water getting past the seal to the gear oil?

Thanks in advance!

Your water and rust are a result of moisture getting in around actuators. If your tractor was worked regularly, heat would evaporate the water, and there would be no rust. These old Farmalls were meant to be stored inside during extended periods of non use.

You may not even need the brake discs. Clean the balls and ramps well, make sure the springs are good. Find a rasp and rough the surface of the glazed discs. My dad ran two of these tractors, with 3 sets of discs; one in each tractor and one set out for rasping, and never bought discs for years. I know 35 years later one tractor was gone, and I was still rotating two of the same sets of discs. The glazing is caused when ramps and balls are dirty, thus the brakes don't release properly. Cleaning these mechanical disc brakes, making sure all springs are good, was and still is an annual job. Do that and they work well.

I put close to 20,000 hours on 300, only ever had the one extra set of discs my dad bought for H and 300. I put 11,000 hours on my 560 and 15,000 on 656 and each had one set of replacment discs. The annual cleaning is the single most important item you can do. My memory is a bit shaky on this but I think the IH operator's manual calls for yearly or every 500 hours.

However you can, store the tractor in under a roof. Then water in the brakes, etc. will not be a problem. But if must stay outside at least put a tarp over the seat and steering wheel so the transmission and brakes are covered.

Be aware most of water that ends up in the transmission seeps in around the cover plate cap screws - the ones recessed into the cover plate. Rainwater also runs down the shift lever and into the transmission.
