Planning to rebore JD LA (3.5"dia. cylinder) engine to .040 over. Been told rebore for sleeving can cause block to crack when center head bolt is tightened. JD parts show only .020 over pistons.Does anyone know if .040 over is too much? What is max bore for LA?
 
Would have to look up what sizes they had. Getting pistons to an odd size would be a challenge. They can be sleeved.
 
Been told rebore for sleeving can cause block to crack when center head bolt is tightened ...do you know max size to rebore without risking cracking block?
