I need some help! I can't figure this out, and I know it's wrong.

What happens is, when the clutch is not engauged, about every 2to3 minutes a loud knock comes from the clutch. I know it's not the main bearing, but that's what it sounds like. After I engauge the clutch thier is no knock or any other problems.
I have had this problem for some time and took it apart a million times over the years. I have been around John Deere tractors about 50 years and I can't figure it out.

Your suggestion and any questions PLEASE! THANKS

Hi JD nut, As said in the posts below, your toggles and dogs, or even the pivot holes might be worn. The other thing to check is make sure the slide pin isn't broke off, bent, or badly grooved. I have seen the cast ear that slides in and out on the pin be broken or worn also. I hope one of us has hit upon the problem for you! Good luck, Don

JD Fan, the first thing to do is make sure the flywheel is tight. If the flywheel is even the slightest bit loose it will knock & the sound will be heard loudest on the clutch side. (put a big 3/4" drive on the bolts as a 1/2" drive probably won't get it tight enough, or use the correct flywheel wrench). If that is ok then pull the clutch cover off & run it like that for a while (while the cover is off look at the inside to see if the clutch adjusting bolts were hitting the cover when it was dis-engaged. Make sure the clutch driver is tight on the crank as that can knock if loose. You should also adjust the brake to hit the clutch pulley before the pulley can move in far enough to hit the dust shield. If there is very much wear on the splines on the clutch driver the disks can rattle when dis-engaged. If you have to adjust the clutch as tight as you say to get it not to slip it probably needs new "dogs & toggles".

Hey JDFan--Just guessing, but maybe It's your bearing in your clutch, could be dry and maybe locking up. When your clutch is ingaged your crank and clutch is turning the same speed. When disengaged your bearing is rolling with the crank while your clutch is stoped. It is important to have your clutch engaged when your tractor is idleing for oiling purposes. Check it and post it so we will all know!! luckydog

Sorry, but I don't think that is it, because I replaced the bearing, clutch plates and new operating bolts. The only thing is that it doesn't stay adjusted after a good day of work in the field. It always needs to be adjusted so tight, that it takes a good hard snap(harder than anything else I own), to stop from slipping.
It has alway been a very jerky clutch, worst in reverse, even when adjusted loose, and I don't think there is any end play(that I am aware of).

as far as the jerkyness, check all your disks to see if they look good, and make sure the other thin drive disk (the one that fits on the main drive disk) isn't warped or cracked. I had one like that, replaced the disk, and it's smooth clutching.....

I'm back JDFan-- I would guess you are smart enought to put cotter pins in your bolts. Without asking someone who knows, I'm lost without asking. Maybe clooney or JohnT might have an answer for you. Good Luck and I would like to find out what you find. Just thought maybe your pivots on your main bolts need to be working very freely for your bolts and springs to keep your adjustment. Like I said just a thought. luckydog
