I currently just took posession of a John Deere 70 Diesel Standard. I have only had it a few days, and am starting to make some repairs. I need some help on how to replace the friction disks in the throttle lever. I am a reasonably proficient mechanic, but I am stumped. I have the lever out of the tractor, which was an interesting venture to say the least, but that is a story for another time. I already have the bolt off that attaches to the spring, and I know that the disks are behind the plate. How do I seperate the assembly to replace the disks?
 

The free parts book from Mother Deere is the first step to decipher what goes where.

There's a dowel pin and a bushing between the two main parts of the lever assembly both going through holes in the speed control bracket. Once the nut & spring are removed they like to stay together because of rust. Sometimes them being stuck together is the only reason the spring can't "put the squeeze" on the assembly to make it work right. I followed much the same path you're in with my 70D some 25 years ago & once I got it apart (soaking, wiggling, tapping & heating) I epoxied a chunk of new band brake lining to the lever (if I remember right) and I slathered the dowel and bushing with anti sieze. It's been fine ever since.

Hope that helps.
 
Thanks all, I got the parts manual and took the advice. Got it seperated and replaced with friction material. Works like a champ!!!
