18. Making sure that the bearing-shaft assembly is right way up, hit the shaft on a block

of wood (not metal) to free the upper bearing from outer tube (photo J).

19. Remove the shaft and hit the lower bearings with a hammer and bar to remove the

lower bearing and seal (photo K).

20. Install new bearings and seal. It is important to install the seal the correct way up.

21. When reassembling, make sure that all parts are correctly in place and that all bolts

are tightened.

22. After PowerPal has been securely reconnected to the turbine stand and penstock

adaptor flange the forebay is refilled and normal water flow is allowed to continue.

Wait until this occurs before reconnecting the cable and appliances.
