jd la rebore

  1. John Deere
    Want to re-bore JD LA (3.5" dia cylinder) engine. Have .040 over pistons but concerned that JD only made .020 over pistons and have heard that re-bore for sleeving can lead to cracked wall when tightening center head bolt. Have you re-bored an LA? Is .040 too much? Anyone know max bore?
