IMPORTANT NOTE TO WORKING ON THE ENGINE CASE
Read this section before you start to work on the engine case. Plan the precise order of assembly so that you can insert the
bearings the first time the case halves are heated.
To press or tap out the bearings, remove the dowels and place the engine case half on a large, level surface. Make sure the
entire sealing area of the engine case half rests on the surface to avoid damage (a wooden panel makes a good base).
If possible, bearings or shaft seal rings should not be hammered or tapped in at all. If you do not have a pressing tool, carefully
tap them in with a suitable drift. Cold bearings usually fall into the bearing seats automatically at an engine case temperature
of approximately 150° C.
If the bearings do not fit tightly in their mounts when the case half has cooled down, they may turn in the engine case when
they warm up. In this case the engine case must be replaced.
