Thank you. I am a 71 lady. Watched you tube to try the repairs. Got my two back tires on ok. Had to find help from a neighbor to undo and put the blade on.
Was surprised at how fast items shipped and were received. Hope you can keep parts in stock, in case I need front tires.

Did not fit the bolt. Threading not clean.
After spending an hour trying to tighten the nut onto the bolt to connect the wheel to the mower I ended up having to go to department store to get a replacement nut.

Spindle and Idlers on mower deck needed replacement.

Difficulty
Easy
Time
30-60 minutes
Tools Used
Screwdriver, Pliers, Socket set, Wrench Set, Impact wrench
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

The plastic was worn away by the drive belt on the pulley causing vibration. The carriage bolt wouldn't hold in it's square hole and it was difficult to get the original locknut off. I had to lift the whole tractor off the floor in order to hold tension on the carrier and bolt to back off the locknut. Then it was easy.
