DRAWING NUMBER 10.020
Installing the Engine Unit
SEE DRAWING FOR PARTS REQUIRED
Recommended 3 persons job. You could leave this job until later but if so
you will need to secure some ballast to the engine mount to keep the
nosewheel on the ground. Please use professionally built engine lifting
equipment (a small gantry with castors) that is placarded safe for the
engine weight (58kg). Many DIY car enthusiasts have such lifts in their
workshops or you can rent one from your local tool-hire shop.
Note. Do not
trust unsupported garage roof beams to take the weight of an engine!
1. Unpack the Rotax 912/912S and read the manufacturer’s instructions
regarding handling and lifting. Locate and inspect the brackets, the rod,
the lug and the bearings as illustrated on the drawing. Select the correct
size bolts with nuts, washers, cotter pins and spring pins. Brief your two
assistants on their parts in the job so that each person is clear about
their area of responsibility. Ensure that you are familiar with the
operation and control of the lifting tackle. Practice before you start the
job.
2. Lift the engine and offer it up very carefully to the engine mountings.
Bolt it in place exactly as shown on the drawing but with the nuts finger-
tight and the weight still supported by the lifting equipment.
3. Re-check 1 and 2.
4. Tighten the nuts as normal and insert the cotter pins and the spring
pins. Give the mountings one more check then
gradually transfer the
weight to the fuselage.
5. Remove the lifting tackle and thoroughly examine the finished work.
Note that the bolts 8 and 9 are secured with locking wire.
