Any common problems with the IH 684's?

I'm going to be looking at one locally with a loader and 2300 hours on it.

Any common problems to look out for?

Thanks everyone!

Hi check parking braking for holding on a slope and
foot brakes for being spongy.

What is the fix for the spongy feel? It has that.

Bleeding those brakes is a different deal than
most brake jobs. They are not power brakes,
however they have a keep full system that the oil
cooler return feeds so they never run out of
fluid. You can sometimes bleed them successfully
by just putting a hose on bleeder, opening it up,
return fluid to filler and run engine at a higher
rpm . This is done without moving the brake pedals
at all. If this doesn't provide a flow you may
have to pinch off the hose coming from oil cooler
to reservoir to build some pressure. Yes, make
sure the hand brake works good. Common to leave
them engaged and take the linings off. Major job
to replace it.

Thanks!

Next question- Any engine or driveline problems common? Average hours between rebuilds assuming it was reasonably cared for?

I had a 560 that the headgasket was giving up the ghost on and don't want to deal with that again. Between that and the fact it was a MONSTER for 5 acres divided up in a few sections with fence, I had to get rid of it (nearly giving it away... It was nice running and purdy).
