Let me try again, I posted this before and got a copy of the repair manual but its way over my head. Is that large screw an adjustment or needs to be replaced??

I could use some advise on the draft control on my 1948- 8-N . With the lever all the way up it does not work, with it 1/3 down it seems to work fine, and with it all the way down and me pushing hard on it works, but as soon as take my hand off the plow drops. I assume I have a worn part, or it needs an adjustment. Also their is a large screw maybe 5/8 just above the level, but it seems frozen. Any suggestions? Thanks Ron

rainy: Mine does the same thing - I've got it blocked all the way down with an oak block for draft control & it works OK. I purchased the "fix" (adjusting jig and cam follower pin plus detailed instructions) from Zane Sherman, but haven't got a round tuit yet.
You will need to pull the cover and fix it. The screw driver slotted bolt is just the detent ball & spring for the lever, but if the mechanism is out of adjustment, fooling with it will not fix anything. You need to get ahold of Zane.

Right on. I got stuck on the trail with the plow down, and i had to do the same thing with a fat stick. this would allow me to get back to the barn. I'm going to send you my e-mail address if you would let me know how you make out fixing it. My mech. skills are limmited. Thanks Ron

Yer assumptions are correct, the lift cove will need to come off, adjustments and replace the cam follower pin. You do know the quadrant izz adjustable don’t ya. Loosen the four bolts and slide it in either direction to find the sweet spot were it may werk in either draft or position mode and hopefully both. If you git Zane’s adjustment jig with the instructions he will give you the tips to git it rite, you also will have a better understanding on how the lift and linkage werk but only if you follow the stuction’s to the Tee and do not skip enny.
I spec the slotted screw head thingamajig izz the cap that holds the ball and detent spring for the leaver, Not chur problem. Also the copy of the repair manual wuz a help'in jester that most would apreciat, lest I would. One more thang, remove the right inspection cover and manualy move the long leaver that goes in the pump as you move the quadrant and see how it werks, if OK its in the linkage. you kin use a lond bar, this also would be a good time to check the lift cylinder fer leakage.

My parts catalog does not give a good identification on the part. I think it is labeled as, Drawbar, Control Arm, Mesh, 8N. It sits on top of a part labeled as Spring, Draw Bar, Control Arm, Mesh, 8N. While it is not adjustable if the spring is broken or missing. You would have problems, possibly what you are describing. It is not an adjustment as it is not addressed or identified in the adjustment procedure. The guy who knows for sure on these boards is Zane.

Thanks Jim for a while i though i was going nuts. I sprayed that screw with Break-off lub to see if i can un screw it and see whats in their. If its a simple matter of replacing a spring I will do the "SNOOPY" dance

Perhaps you are talking about the quadrant stop lock? It's there so you can set the lift lever to return to the same place on the quadrant.

Sorry guys i'm not making my self clear. The bolt or screw which is pretty large the size of the regular bolts around it, except it has a screwdrive slot(large)right above the small lever. your right he did send me a 8 page doc that explans how to redo the hydrolic system, but thats more then i can do. I have tried to place a picture here but it does not seem to work.

I think you were sent the information from Dunk because Its not clear what your problem is. Anyway the short lever controls wheather you are in draft or position mode. If the lever is vertical or up you are in position mode and the lift follows the large lever. If the short lever is in the horizontal or down position you are in draft mode and the lift is either up if the large lever is up or down if the large lever is down. the lift does not follow the position of the large lever smoothly. If you can specify where the 5/8 screw/bolt is you are asking about, maybe refer to the info Dunk sent, might be able to better answer your question.
