thank you. The spindles i have replaced need you to be able to take off the top nut and 4 screws and the blade to to remove from the top . It is a Husquavarna YTH18542. To remove the spindle I have to be able to secure the blade so I can then remove the top spindle bolt. I have now been able to resecure the blade tightly, so will now try to remove the top bolt on the spindle, then the four holding bolts. Since I cannot remove the blade as the bolt seems to be in a stripped hole, I am hoping I can now remove the top bolt as I have retightend the bolt and blade. Thus with that static, the top bolt should come loose? Only problem now is the I would have to cut the blade bolt off as the blade prevents the spindle come from out the top? Hope this makes sense. My only other idea is to torch the blade and try to get it unbent, so I could still use it. Otherwise even on highest cut setting it drags.I am really pissed off that the last spindle I put on the bolts came loose, now instruction to use liquid stop washer.
