4.17.3 Reinstallation of the powerplant
Reverse the procedures for removal mentioned above. Note sections 4.12, 4.14,
4.16, 4.19 and 4.21!
Use only new selflocking nuts for reinstallation. Use Loctite 243 to secure all
threads and bolts without selflocking nuts.
Use new gaskets for the coolant outlet.
Reinstallation of the starter ring gear
1. When reinstalling the starter ring gear adjust the propeller position versus
the engine compression point according to sect. 1.11.4 via the drive belt.
2. Install the screw at the crankshaft without using Loctite and tighten with a
torque of 100 Nm (73 ft lb). Hold the Propeller to counteract the moment.
3. Tighten the drive belt according to section 4.12e).
4. Reinstall the proximity switch and check its adjustment according to sect.
1.14.15 and correct if necessary.
5. Reconnect spindle drive and gas strut.
6. Rig the wings to the fuselage and secure the glider. Start the engine, apply
full throttle for a short while (max. 30 seconds) and stop the engine again.
7. Retorque the screw at the crankshaft with 100 Nm, to accomplish this the
spindle drive must be disconnected again.
8. Start the engine, apply full throttle for a short while (max. 30 seconds) and
stop the engine again, retorque again. Repeat this procedure until the
screw can’t be turned any more with the same torque. Normally it is
necessary to repeat the procedure 4 times. After the last retorque remove
the screw, apply Loctite 243 and torque again with 100 Nm.
9. Install a new selflocking nut M10DIN985-8zn to the spindle drive bolt.
10. Check if the propeller position versus the engine compression point is still
in the limits. If necessary correct according to sect. 4.12 f).
