Case IH 585 clutch failure

ccaissie · Aug 12, 2018

Got a call from client, said his 585 clutch 'went out' on him, won't move now, though he limped it in from the field.

Said it was leaking badly, which puzzled me. I was in Vermont when he called me. Leaking? Then I realized it is a hydraulic Wet clutch.

I'm back this a.m., and will take a look at it, but I know little about troubleshooting a wet clutch....I'll report back after inspection, and expect to expand on this discussion...will do more research...

Any first words of advice?

Hi CIH 585 has a dry clutch but if it has a cab on it the clutch pedal will activate a master cylinder down on the left side of the torque tube, no cab clutch pedal is a mechanical connection.
There is an inspection plate at the very bottom of clutch housing. If there is oil leaking out of the inspection plate it could be either crankcase oil or hydraulic oil leaking. If it is crankcase oil the rear main seal is leaking. If it is hydraulic oil it can be leaking from transmission/PTO main shaft seal or there is a cover on down lower in bell housing that can leak as well.

There are youtube videos for 454,574,684 all the same except for cab models with master cylinder activation.

Hope this helps

Oh yeah! So the info re hydraulic wet clutch is wrong...maybe they meant that it is hydraulically activated.

Yes, I looked over the leakage, and it is blackish, coming out of the bottom of the case. Client's description of the problem indicates the slave cylinder might be bad, can't get it into gear...grinding and all that. will pull the inspection covers and get in there to Dx the cause.

Thanks, will report back in.

Hi most likely if it does not have a cab is the throwout bearing has seized and worn the fingers off the pressure plate.
If cab then also could be the clutch activation cylinder. My brother's 684 had the throwout bearing almost seize but enough to wear fingers off pressure plate fingers and had to shut engine off to get it into gear. We did a split and did clutch, pressure plate and throwout bearing. If rear seal is leaking crankcase oil some Lucas oil seal treatment may be short term fix. On my brother's 684 it had leaked a little crankcase oil out the inspection cover for years and the first time we did a clutch job and took the flywheel off to have it turn we noticed the bolts on the rear main seal were loose, we torqued them to spec and no more crankcase oil leak.
