43 years old brakes

[Bornfree]

First brake replacement on a 1981 Ford 4600 tractor. Not sure how many hours on it because the clock stopped working around 15 years ago at 24,000 hours.

Were they wet brakes?

I had the offside trumpet off my 4600 a couple of years ago - by heck they are heavy. I made up a wooden cradle to hold it and used a jack up table under it. Re-assembling it the alignment was a pain until I made a pair of extended studs that guided it back nicely.

Good luck.

What's wrong with them? looks like there is at least another 20 years left in them.

There's only 0.5mm wear on the disc's and plates but unfortunately that's enough to let the actuator turn and the pull rod cuts through the seal.

So they are like a clutch plate, albeit wet ?

A busy little tractor (at least early in its life). That would be about 6 1/2 hours running at PTO engine rated speed for its first ten years!

As I recall, we could actually manage 27 recorded run-hours in a day with a Ford 5000, with pump opened up to about 2700rpm, cultivating day and night. PTO rated engine speed was 1900rpm.

It's been on a 6 ton feeder wagon since new. Running seven days a week from march till December. I must take a picture of the PTO shaft the splines are nearly gone.

Pto shaft. And its still on the original pto clutch.
