Is it a system from a 425, 445 or 455 with the same size deck? If it is not maybe probably not. Roger

Howdy all,
This weekend I replaced the primary and secondary drive belts on my 78 JD210. Getting ready for snow blower season! I also picked up a new secondary idler return spring part number M41946. I also ordered a Variator spring but they were out of stock. I have noticed the old gal would slow way down going up hills. I could grab the clutch pedal and bring it to the top and she would speed up. As soon as I let go the clutch pedal would drop and the speed would drop as well. Earlier in the summer I serviced the variator pivot bolt, and variator, adjusted the variator spring (Shortened it), and adjusted the variator with not much improvement. Then I read in the archives about other members having similar issues and resolved them with a new idler return spring. Well guess what? My variator problems where in fact due to the secondary idler return spring! The spring I removed was much longer and smaller in diameter than the new one I just got. See picture below. In fact the way it was routed is suspicious. I always heard a spring stretching sound when I would push in the clutch. That long spring was rubbing on the rectangular cut out that it passed through. I attached my new spring in a small hole in the frame. This hole lines up with the spring and required me to stretch the spring about an inch to get it mounted. I hope this is right. If you have a picture of where your secondary idler spring is attached please share. My clutch pedal now comes up fast as soon as I get my foot off it. I have a steep hill and my driveway is all up hill to the street. Now I can blast up those in 4th gear with the variator all the way forward. This site and its members are amazing. We all learn from others experiences. I thought I would post in the event it can help someone in the future.

Scott,
I think I screwed up! I just went to the JD parts site and the spring they show looks like the one I removed. The one I installed is for earlier serial numbers. Awe man! But it works so good now. I guess I will reinstall the old spring and see how things go. Like Homer Simpson sez DOH!
