Replace the Drum drive module

Swap the DryStar 5300's Drum drive module (spare part CM+343338.X) by working through four prerequisite covers/modules to reach it, then unplugging 3 connectors and removing 4 screws.

Applies to
Drystar 5300, Type 5365/100 (source Chapter 3.5 §4.4 'Drum drive module', Edition 1 Revision 7, 2005-08-05) — replacement procedure for the Drum drive module, spare part CM+343338.X. This is the module the error catalogue designates MOD06 (see Related).
Personnel
1 technician · Basic field-service skill for the module swap itself — unplug 3 connectors (A), remove 4 screws (B), lift the module out (and the reverse to refit). No calibration or software step is called for in this entry. The overall job's real complexity is sequencing: it sits behind two other removal procedures that must be done first (Main drive pulley & Drum belt §4.1, Input sensors module §4.2), which themselves sit behind the Front cover (§1.1) and Left side cover (§1.3).
