Disconnected mower deck. Took off mounting bolts and idlers, put on new ones and tightened the bolts, put new spring on and reconnected the mower deck and belt. Smooth as silk!

Spindle and Idlers on mower deck needed replacement.

Remove old spindle and idlers with wrenches and socket set. Screws that secure spindle are self tapping, so take your time and make sure the new bolts cut a good thread in the spindle assembly. Secure the spindle with the four bolts, reattach the blade and tighten the bolt holding the blade to the spindle ( I used an impact wrench on the lowest torque setting). Reattach the new idlers proper side up (best to use your phone to take a picture of the whole deck before you disassemble anything) and any assembly you are not familiar with to make sure you get it right. Put the new belt on, reattach the deck to the mower and get to mowing grass! Online pictures of older mowers showing the entire assembly are hard to find. Take your time, take pictures, and do one thing at a time, don't tear the whole thing apart all at once. Use new 5/32 cotter pins (about 6-8) to finish it up right. Good Luck Mike
