I damaged my main pulley trying to use a puller to take it off 😢 I’ve been realized I have the key way and it’s still. Is there anyway you could give me some advice or I can send a video?
If you broke the main engine pulley, you can buy a new one. The parts diagrams are on jdparts, but I usually order from Green Parts Store's website. Here is the diagram that includes the drive belt and all the pulleys. As seen in the list on this page, the engine pulley for a serial number 0-70000 is AM118395. partscatalog.deere.com/jdrc/sidebyside/equipment/69927/referrer/navigation/pgId/65808723
I'm using the John Deere service manual TM1574 (TM1760 is for gen2, s/n>70k) and CTM39. Send me an email and I'll tell you where you can get them (you can find my email by using Google on my full name).
