  • Slew Drive Installation and Maintenance Manual

    Liner bolts fail (break or loosen off) for a number of reasons but the vast majority of these can be eliminated if the pre-load is correct. Fatigue failure is the most common mode; this is almost invariably due to pre-load that is too low. This can in turn be divided into 3 groups: inadequate original tension, consistency and high relaxation.
