My old SB-14 John Deere needs a new drive belt, but in order to replace it it appears that I need to remove the blade clutch assembly from the shaft. I Have the lower portion off, that connects to the blade and is bolted on to the end of the engine shaft. Now I'm unsure how the other half connects to the shaft. Is it pressed on there and has to be pulled off with a puller? Is there a special tool that fits the end of it (there's notches around the bottom edge). Also, I was able to free the main spring, but getting it back on there appears to be quite a chore... Is there a trick to that that I'm not seeing? I don't want to mess up the clutch by attempting the wrong way to remove it! I'm going to run to out John Deere place first thing in the AM to pick up a new belt, I'm going to try to see if anyone there knows, but I'm betting that the mower mechanic dosn't work Saturday monrings. Good thing I only use this mower a few times a week! Thanks in advance to anyone that knows!!
