just in case anyone else has the same problem-
the brake petal valve on my 75b loader project was leaking so bad that the machine couldn't build up pressure-- so i got the bottom parts out and went to the local parts place to get new seals---heres what they said---you have a e-2 valve---no parts
however if i buy a new e-3 valve you can take the parts out of it and install in the e-2 body---68 bucks for the new valve---
i ordered it and it came in the next day--i had some time so i decided maybe i would just install the whole new valve instead of just switching the internals-- it takes awhile to get the old valve out, the pins and bolts that hold the pedals in place were of course rusted up good and your all scrunched up under the steering wheel--if i ever do it again i'll make sure i loosen the fitting on the steel tubing fitting before i take out all the bolts.. but out came the old valve --except for some grease and grime on the outside, the inside of the e-2 valve looked almost new--so instead of fighting all the fittings and trying to get them all lined back up right- leak free- i indeed swapped out the old internals for the new ones---kinda tuff getting the valve back in --one trick i used to get the most forward nut back on bolt for the treddle flange was to take a 1/2 inch open wrench and a filter off a cigarette--use the filter as a way to hold the nut in the wrench, got the bolt and nut to line up and when tight just pulled the wrench free- it also took a while to get the roller thats in the brake pedal so it would turn.. but its now all back togeather-- 2maro will tell if i get a ful tank of air so i can try to bleed the brakes--or at least 3 of them---when i bought the machine i found that someone had removed the left rear caliper and rotor--- but for now 3 brakes are much better than none at a all
