Lawn-Boy 320R Idler Pulley Spring

The rotor on my Lawn-Boy 320R stopped spinning at the end of last season. I figured the belt had gone bad but instead found that the tensioning spring on the idler pulley had popped off. Looking at the manual it shows that the spring should go from the idler pulley to a bolt. This however doesn't seem secure enough. I'm considering putting an additional nut on the bolt to prevent the spring from being able to pop off. I can't tighten it all the way down without bending the spring so I figured I'd use some Loctite on the nut to keep it from backing off. Do you think I'm just overthinking this or should I add the nut as I described? Is there some other solution you guys think would be better?

I unfortunately am unable to add links to my post because my post count is not great enough. I think some images of the problem would really help clarify things though so here are some links to the diagram from the manual and a few photos of the problem. To view them you'll have to replace [dot]com in the following links with .com:

Thanks for the help!

The easy thing would be to add another not on there. I think I would drill a hole in the end of that bolt and put the spring through thru hole and be done with it......




I am deathly allergic to shovels!

could it be that the spring has sprung and doesn't have enough tension to hold on

bad69cat, not a bad idea to drill a hole at the end of the bolt, I'd definitely trust that to stay better than an additional nut. It's possible it even already has one, I didn't think to look for a hole on it. Thanks for the advice.

detdrbuzzard, good thinking although it seems like the spring hasn't stretched. After putting it back on the rotor now turns again I just don't trust the spring to stay in place.

Smile I think my Toro CCR1000 is the same machine...

I haven't had it apart lately but seem to remember there being a tang/tab for the upper end of the spring to hook too. Also be careful when putting the cover back on, if you don't get the belt aligned inside the curved guides just right it rubs on and wears both the belt and the plastic cover.
