Did you replace the primary drive pulley? Its about $52 from General Transmissions. Was yours ok? I haven't torn my apart yet to see if its bad. I was able to slip the secondary drive pulley out without taking out the transmission. I don't think my primary is bad from what I can see. I was just wondering if I should replace it while I have it apart. Also what Idler pulleys are they that you replaced? Are they for the mower deck? Thank you for the awesome write up and pictures!Parts are all in I will complete the install tomorrow with loads of pics. But first the part is confirmed to be from General Transmission and the pulleys are JD. Also came with a new belt and instructions even though it’s pretty straight forward it’s a nice to have.
Then I noticed something, the pulley looks a little different. It’s beefier, seems they upgraded the stalk and the unit feels heavier. Instead of a hex shape at the top and bottom it’s thicker and goes the whole length and sleeves in so there is no space. I wonder if this added to the occasional slip or lack of top end. I noticed one of the older stalks ends looked to have some corner wear on the hex points.
