NI 5209 slip clutch questions

Clodhopper Pete · Jun 20, 2013

I just bought a 5209 (white paint), an after reading some of the archived threads about the machine I figured I had better check and make sure that the slip clutch was working. It was completely seized up, so I took it apart and am cleaning it up.

My first question is are the 2 thinner interplates supposed to be cup shaped or should they be straitened? They cupped towards the gearbox. Secondly, the AGCO dealer says there is supposed to be 4 slip discs in there, which would make sense to put one between each interplate, but it seems like the only ones that would be able to slip would be the front 2, as the 3 interplates are splined into the hub or whatever it's called.
Thanks for help understanding this and getting it back together right.

I bought mine in "91, burned out the clutch, and it was updated to a newer style- had one more plate than original.

You may have a very early 5209/slip clutch. The "interplates" as you describe may be what my service manual calls "springs" and they are cupped and face the rear of the unit. There should be 3 friction disks separated by 2 plates ,with the last disk being against the clutch hub. The last friction disk(going front to back) goes between the hub and pressure plate. MY service manual suggests that early models have only 2 friction disks in total. I would suggest having your AGCO dealer print you a page (9002-3)from the service manual or go on-line to the AGCO on-line parts book. Your description of the pieces and how they are splined doesn't square with my documentation, So, I can't be of any more assistance.

Thanks for the info. I am guessing I must have one of the 2 disk ones. If I put an third in there going toward the gearbox it would have to go between the splined disk(is that the pressure plate?) and the first spring.

How well does the updated one work? I got mine back together and it was mowing great at about 7mph. Then I took a break to go to my kids' play, and when I got back I can't even keep it going in 1st gear. When I took it apart to clean it up and replace the disks it looked like someone had welded the back spring to the hub at one point, so probably the clutch isn't enough for this mower.

Those "cupped" washers are actually Banvel washers or springs. They are the springs that put the pressure on the clutch disks. If you have it together incorrectly they will not work. Also usually you can't just add a plate/disk.

You really need to get a print out of what it was supposed to look like. IF it has been apart before it very well could have been put back together wrong.

My service manual came today, and though it shows 4 disks for that clutch I can see where all the parts for my 2 disk clutch go. I took it apart again this morning and roughed up the metal parts a bit with the angle grinder and it worked real well for about 30 minutes until one of the driven gear shafts that the turtles bolt to sheared (I think unconnected to the clutch issue). So $310 later it looks like I am going to learn how to pull the hex shaft (hopefully not have to cut apart, but I'm not counting on it) and replace the gears in a disc drive unit sooner than I expected. I didn't pay a whole lot for this machine (probably too much from hindsight) but it looks like I'll be making up the difference in parts and aggravation. I will say that in the short periods between breakdowns it does a nice job, so I am hoping we can get past this awkward first date.
