Smooth rough spots, scores, burrs, galling,
and gouges from damaged machined and
polished surfaces so that part will efficiently
perform its normal function.
The finish of the repaired part is to approxi-
mate that of the original finish.
In performing any of these operations, criti-
cal dimensions must not be altered.
Remove corrosion from all parts of material.
To remove rust or corrosion, use wire brush,
abrasive cloth, sand blast, vapor blast
equipment, or rust remover, except highly
polished surfaces.
On these surfaces, buffing or the use of cro-
cus cloth is recommended.
Check tubes and fittings for cracked or split
condition.
Check tubing for kinks.
Replace defective fittings.
Replace damaged tubing with tubing of
same size.
Take care in making bends in tubing to pre-
vent kinking of tubing.
All tubing and fittings must be completely
clean on inside prior to installation.
