Best clutch to put in a IH 574

Wondering what the best type or brand of clutch there is to put in a IH 574 with a loader. Need to replace mine and I want to do it right. Can a 12" clutch be installed and would it be better than the factory 11"? I have read about the number of pressure plate springs etc. but am lost on what would be the best option and where to go to buy it.

Can't help on brand of clutch, but putting a 12" will need a bigger flywheel.

12" not impossible, seems to me the 4x4 & 5x4's were 11" with a 12" option where the 6x4's were 12" standard

Also, have your flywheel checked, it may need surfaced to be true or the new clutch won't work right.

Hi Brett, the last 3 clutches that I installed in a 74/84 series tractor were re-manufactured clutches and pressure plates sold by CaseIH at a very competitive $$ and they had a core exchange as well.
The most expensive part per pound was the clutch release bearing at $60. I always use the HD pressure plate and 6 pad clutches. You should check the flywheel and possibly have it ground to spec. If you have the flywheel off, re-torque the cap screws on the rear main crank seal. To remove the pilot bearing, I have a carriage bolt with a head that just fits through the shaft hole and the lip on the head catches enough of the bearing to extract it. Others on this forum have suggested that filling the cavity behind the bearing with grease and then driving a shaft into the grease will push the bearing out.
On re-assembly, I place pressure plate and clutch on PTO and transmission shafts and put tractor almost back together but leaving enough of a gap that a long screw driver can be engaged in the ring gear and using one of the bolts in the casting as a pry point, I use the screw driver to rotate the engine to install the pressure plate bolts through the clutch inspection plate on the bottom of the bell housing.

Be careful

You can uprate to the later Rockford clutch used on the "95 series tractors but you have to replace the flywheel to do it.
