One Brake Out, Power Steering Out, Now Hydraulics

Posted by Looking for IH Bug, RAS o on July 21, 2003 at 08:47:29 from (67.241.68.72):

I have a 674 diesel that the PTO and Power steering comes and goes, PTO will start if I raise the control arms. If I raise the auxliary outlets (lower right side handle by the right foot step) everything works, has soon as I release everything stops.
I can hear what sound like the engine under a load when I engage the auxilary outlets, Am I causing high pressure verses low pressure when activating the handle?

IH Bug and RAS thanks for your help thus far.

IH Bug Yes, I lost one brake just before everything went to crap. after the tractor had sat thru winter I noticed the left brake was alittle weak (I thought maybe a bad mastercylinder)
I started mowing hay with a conditioner and about 15 acres in I started losing PTO speed, I checked fluid and was alittle low (Not quite to the low mark on the stick) so I added some and the PTO worked fine and I finished up mowing.
the next day I hooked the tedder/rake up and headed to the field as I started I didn't think the PTO seemed just right with the RPM. I adjusted the control arm and noticed the PTO speed had increased with the movement of the arms. I returned to the Barn to check filter.
Thanks to RAS I located the filter and changed the fluid.
I did noticed some fine shavings in the Hy-tran
oil but not alot. the oil in the filter was quite dirty so I drained the fluid and changed filter and fluid.
My problem still persist.

What is the fix for this? take everything out and replace the MCV.
Should a International Dealer do this repair?
Is there a repair manual for this tractor, if so which one is the best.
This tractor has 6200 hrs of Mostly bush hogging and baling :)
Any help would be appreciated greatly!!!!!
Thanks Kevin
