Thanks! I'll move forward.Replace the gears facing the correct way, theres an arrow on them, arrow facing towards you, and replace them exactly (new gear arrow should be in same position as old) put a small mark on the block were the arrows where. As for putting the chain on, you have to put it on both gears before sliding on the shafts. just make sure that your new gears arrows are in the exact same spot as the punch mark.
Great idea biscuit!Sounds like the ID casting issue PTSchram referenced in his post right above yours. I would recommend calling or contact him since he already called it out before you got the part. Sounds like it needs some cleaning on the inside part of the gear. Don't just go to grinding...talk to him first. This is good info for me as well since I might be doing something similar soon. Keep us updated.
