I know, I'm a pain.

New clutch in my 966 back about 100 hours ago; tractor pulls just fine.

However, I started noticing it "grinding into gears", it is getting worse in the last day or two and it seems to have an awfully lot of free travel on the pedal. It has the hydraulic slave.

Could you go thru that "sure fire" method of clutch adjustment you do? I went thru the archives, but can't find it.

Please?

Allan

well on a hyd. clutch ya want 9/16th free travel from the back of the pedal shaft to the floor board , there is and arrow on the clutch pedal massure from the arrow to the floor board with the engine off and see what ya got . and if ya need to make any adjustments will go from there also check and make sure that the cylinder is not getting loose on the mounting bolts . To make the adjustments first unhook the trans brake and the foward clutch rod by removing the pins , next puh the clutch rod as far back into the cylinder next loosen the lock nuts on the rear clutch rod and adjust till ya feel resistance and lock it down . Now ya want to get place something that is 9/16th. thick between the clutch pedal and the floor plate , then ya hold the clutch bell crank foward till ya feel the throw out bearing touchen the clutch and then adjust the front rod out till ya can slide the pin in freely . Next ya want to adjust the trans brake ( this is when ya need a spare foot to hold the clutch pedal down aganist the stop loosen the lock nut on the trans brake rod on the right side of the tractor with your hand hold the lever of the trans brake back then adjust the clevis till the pin will slide in once this is done let the clutch up (tractor does not have to be running for this )next add one turn to the clevis , now depending on ware of all the linkage due to age and ware ya may have to go 1 1/2 turns ans at times i have had to go 2 turns to get it to work correctly . Next it is the dump valve here the engine MUST be running tractor in PARK here again it needs a helper . First back the dump valve adjusting bolt out about 5-6 full turns Depress the clutch pedal down to the stop and hold , the RED teltale light should be on now start turning the adjusting bolt into the clevis and turn till the teltale lite just goes out as soon as it goes out STOP let the clutch pedal up shut off tractor then add ONE MORE FULL TURN TO THE BOLT AND LOCK . Test drive tractor.

Ya should it is incorparated into the OiL LITE in the gauge cluster and if it is not working then ya had best FIX it . The 1086 sets a littel differant and the 1256 unless it has a hyd assist clutch it set about the same as a 706 other then the free travel on the pedal.

You mean the oil light should come on when you push the clutch on the 1256?? It's never come on since we bought it in 97. Where's the sensor? It has the hydraulic assist from a 1066 on it, installed by us.

I think it's time for me to find some good shop manuals for those tractors... recommend anything better than I&T?

Thanks!

Well the switch is SUPPOSE TO BE on the backside of the MCV , looks like and oil pressure sencor and a Gray wire to it .And yes it should come on each time ya push the clutch down . As for adjustment on it use the same that i gave Allen . No scratch the lite in the gauge cluster it should be on like on a 1066 on the right ft. face of the lower right dash. Hey it's been a rough day and have the head ach form hello.going on at the moment .

Thanks Bud,

I'm gonna print it out this time.

Makes a heck of a lot more sense than the way the IT manual says to do it. Your way allows for wear and so forth.

We'll give 'er a shot.

Much appreciated,

Allan
