Information
The engine mounts must be aligned using the engine carrier.
The engine mounts differ (left/right) and must not be interchanged.

1. Position engine mountings on the support arm. When doing so, note the positioning pin on the mounting. It must engage in the recess on the support arm.
2. Position new fastening nuts and screw them on so that the positioning pin cannot pop out. Do not tighten the fastening nuts.
