120. At the same time as the bomber pilots of Einsatzstaffel 234 were training at Burg, the ground crew of 3. Flughaffenbetriebskompanie (FBK)/76 were learning to service the Arados. One of their most difficult tasks was switching out the Junkers Jumo 004B engines, which weighed 745 kg. (1642 lb.) each.
First the access panels of the engine nacelle had to be removed, the side panels dropped down for access to the securing bolts and, in this case, a special gantry with block and tackle wheeled above the wing.

121. An angled lifting bracket was brought under the wing to attach to the engine's centre of gravity on both sides.

122. The J2 hose connection had to be uncoupled as well as the bundle of wires coming from inside the wing.

123. After the securing bolts were removed, the engine could be carefully manouvered away from the wing.

124. This photo shows clearly where the lifting bracket hooked at the centre of gravity of the engine.

125. This is a view of a crane with a motorized winch being used with a different shaped lifting bracket. Again the Arado has the yellow ring of the Einsatzstaffel.

126. In this case, the bracket is C-shaped but also hooks into points of the centre of gravity.The bundle of wires can be seen.

127. Once the securing bolts were back in place, the wiring and plumbing could be easily re-connected, and the nacelle panels re-attached.
