Why doesn't my 3 point lever on my 8N stay in the position where I set it? The lever has been creeping down since the cold weather. Drops to the lowest setting. There doesn't seem to be any friction do dad to cinch lever in place. Thanks

Part number 83977032 is a friction disc that probably needs replaced. It's item 21 on the illustration below. You might try tightening the castle nut, item 42, a bit first before replacing the friction disc. That might be all that's needed.

Thanks Jinman, I didn't think tightening that nut would help but I will take another look at it. Thanks also for taking the time to post the picture. Jim

Jinman, That nut was indeed the answer. A simple tightening and wa la, problem solved. I feel somewhat silly now for asking the question. In 10 plus years I've never had to mess with it. For some reason when I initially looked at it, I didn't think tightening that nut would solve anything. I should have known better! At any rate, many thanks for the tip and picture. Jim

If I'm remebering correctly, the friction disc is made of cork, albeit thin, which can be fabricated locally.

On my 1700 it is a metal washer and not so smooth surface. I don't think cork will last long enough. in a different application I have seen them with almost leather like material.

JC,

Yea! The simple solution is always the best solution. The illustration is from the New Holland website. They have a full set of 8N parts diagrams. I love that site.

JC,

0n the N it is a ruberized cork disc... and if original, his probably shrunk up a bit, and or got hard and wore down so that it became loose. If it had broke or worn so much he couldn't adjust it, it isn't too hard a deal to remov ethe lever and put a new one on.. I've had to do 2 or 3 in the last couple years.

I wondered if a guy can make two thin round friction disks /washers out of EPDM (roofing rubber) or some other suitable material. I'd probably would cut two notches wide enough and a bit wider that the threaded rod. I'd then loosen the caste nut and and break off the fiction disk without further dis assembly, at that point I install two washers 180 degrees opposite of each other and tighten the whole thing, do you thing it might work?

No.. i don't think it would... I'd be afraind the material would roll at the cut notch since it would have to be 1/8" material for 2 of them.. plus.. if you are backing off the adjuster nut to the point to slide the lever back.. why not just slide the lever off and use the correct disc?? it's like 5 minuteds more work... pull 2 screws on the lever out, pull the big handle, then the discplate can slide out without taking the quadrant apart, clean up the surfaces, add new friction disc followed by the discplate and then put the handle back on.

if the discplate is stuck, leverage it off with a couple screwdrivers and some loosenjuice taking it slow.. when you reinstall, add neversieze to the shaft , key and keyway..

I've made disc out of thick innertube and thick leather or ruberized cork.. however.. the disc from tisco, sparex or cnh is so cheap anyway.. it's not worth the bother to make on unless you are broke down in a field and don't feel like a trip to town..
