This is the ninth in our series of posts where we are sharing drawings for the White Horse CAD Wobbler Engine. This week we will look at the Wobbler Engine Base Sub Assembly.
Next week we will look at the Wobbler Engine Piston Housing.
Lets look at the Wobbler Engine Base Sub Assembly in a little more detail. If you would like to refer to the PDF engineering drawing it can be found by clicking here..P9999-13001_Rev1
The Wobbler Engine Base Sub Assembly forms the back bone of the engine. All of the major components such as the main shaft, piston and piston block will be fitted to it. So it is important that all of the bolts are tightened adequately and the vertical support is perpendicular to the wooden base.
Detail C on the left shows how the socket set screws hold the flywheel bearings into place. you can see the the top of the screw is below the surface of he bearing and tightens against the base of the flat bottomed hole. This will stop the bearings rotating and hold them against the face of the vertical support.
It is also important to ensure the vertical support is assembled in the correct orientation. The exploded isometric view on sheet 2 of the drawing details exactly how the components fit together.
