so i had to do a little work to the old 4020---  needed a clutch, injectors and injector lines.

decided to use A&I products parts---  flywheel and injector lines.  

anyway got the clutch all together---  started it up and backed it out of the shop.  then notice the tractor is shaking BADLY. pulled it back in the shop and checked the crank run out--  over .015" out of round!  dang...

called them, they said send it back and i'll get a refund.  i did so.  put in an OEM deere flywheel, fixed the problem 100%.  it had only around .003" of run out.  no shaking at all.

anyway about 2 weeks later we get an email from A&I stating that they will not refund the money for the flywheel because the clutch was improperly adjusted causing it to burn the flywheel,  and it is balanced properly.   this is 100% impossible!  it only drove about 50' total, in reverse and 1st gear!  tried explaining this to no avail.  they are just refusing refund for no reason.  so i'm still fighting with them on that.

and none of the injector lines lined up.  they were all way out of whack.

just so you guys are aware of what kind of company they are and what kind of parts they're selling.
