Gear unit with block flange

The front area of the block flange must be absolutely free of grease.
This is essential for safe and reliable torque transmission. Do not use contaminated
solvents or dirty cloths for removing grease.
Tighten diametrically opposed tensioning bolts to full torque.
The joint bolts must be tightened to the prescribed torque. For the correct torque, refer
to item 6.22. Bolts of the minimum strength class 8.8 must be used. The transmittable
gear­unit torque is limited by the bolted joint on bolt circle K1.
