steering clutch properly is to remove the track (find the the master track pin usually slightly longer than the others) lay the track on the ground remove Tate the only way to free your seat assembly and rear side panel, and the two square covers behind the levers then un adjust the clutches and unscrew the grease tubes to the yokes and then un bolt the top cover and lift it straight up and away,you will then be able to see the brake band and drum if you release the adjustment on the brake band you should be able to remove the brake drum and final drive in one go. Once you have released the brake band undo the bolts that hold the final drive to the main gearbox about 20 bolts i think wrench size 3/4 inch you don't have to remove the sprocket if you have help you can rotate it past the track frame and carefully slide it off the steering clutch pack leaving the brake band in the rear casting be care full on removal as you can brake the teeth off of the fiber discs a few broken ones wont matter but if you break a lot of them off it will then you will need to remove the clutch pack from the tapered shat by bending the lock tab on the large centre nut and unscrewing the nut you may need a puller to get the clutch pack of off the tapered shaft,once you have it of the shaft cut the lock wire from the 1/2 inch dia unf bolts you if you remove two opposite bolts i think they are about 3" long and replace them i think with two 5" bolts screw them in tight,then remove the other 8 1/2" unf bolts then slowly a little at a time undo the two longer bolts witch are now compressing the clutch pack once you have the pressure off you can then disassemble the clutch pack lift the top off and you will have a friction disc and then a steel disc 8 of each i think. The best way i have found to clean the metal parts up are grit blasting you can carefully clean the friction discs with a grinder and wire wheel with light pressure,if you tractor has been stood as long as you say their will be no wear on the clutches i have 3 Allis M,S and i have had to free all of the clutch packs in them as they were all frozen i tried all the tips from the so called experts from filling the compartment with diesel to tying it to a tree all you do with that method is strip the pinion shaft or bull gear as you say it is ex army some of the military ones had special pinions and bull gears i think there was 250 tractors made for the military as i have a military service manual witch lists the quantity made parts are still available for the steering clutches but as i said earlier i have 3 Allis M,s and they have the original clutches in them as i said they were frozen but i cleaned them up and reused them i did have 1 set of new ones but i used them in a K crawler. Tractorparts.com do reproduction friction discs and steel discs if you should need them they are based in Boise ID phone no 208 342 8911 it is a tough job but as i said i have done 3 so i can now do it with my eyes closed if you need any more advice please email me. sorry this is so long if you need anymore info/help email me everett048@yahoo.com regards Mark
