Bearings

^ Install needle bearings with the inscribed side (thicker metal) facing the drift.
^ Heat the inner races of taper roller bearings to approx. 100 °C (212°F) before inserting.
^ Do not interchange the inner and outer races of same size bearings.
^ Always replace taper roller bearings which are mounted on a shaft together and use bearings from a single manufacturer
^ Lubricate all bearings in transmission with gear oil before installing. Apply oil with special care for measuring friction torque.
