Inspect commutator for cracks or burrs,
wear, scoring, spalling or brinelling. If any of
these conditions exist, replace commutator

plates bonded together to form an inte-
gral component not subject to further
disassembly for service. Compare con-
figuration of both sides of the manifold to
ensure that same surface is reassembled
against the rotor set.
