Equipment: Kubota ZD18 2yrs old...app 400 hrs Earlier in the year i hit a stump in some overgrown grass, at the time i thought things were Ok...but later that week when removing the bolt that holds the blade, it stripped the threads while removing it( slightly bent). I purchased a threader and new bolt and all was well.... NOT!...after removing them several times the threads are now sloppy. I've noticed the other spindle threads have gotten a little slop also after repeated impact wrench changes. All spindles are fine otherwise. Spindles are 90.00 a piece....Do I a. suck it up and replace them all b. buy a high quality helicoil kit c. trade it for a new anvil?
