Repairing the Frame.
a.
Repairs to the frame are limited to replacement of damaged or distorted draw latches and to welding of
cracked joints in the frame members. In case of severe bending of frame members, replacement of the frame is warranted
to avoid alignment and vibration problems. The frames are manufactured to close specifications and engine units and
compressor units are not required to be a matched pair. In other words, any engine section will fit satisfactorily with any
compressor section. Hence, it is not necessary to replace both frames if only one is damaged enough to require
replacement.
