All you have to do is get your track pulled off to the side and don't take it completely off unless you have the gator clip link. If you do have the link put it around your front idler and unbolt it keeping tracks close by---by blocking or chaining. Pull your idler out and rebuild it. Contact me if you need anything else. Good luck.
Darinray, thanks for the reply. Can you please give me some more details on what you mean when you say, "pull the track off to the side". Do you mean you can get it out of the way for removing the idler without unbolting the track?
Also, what's a gator clip link? How would I identify it. Yeah, ok i'm an ignoramus, but hopefully not too old to learn. Thanks!
