Good Morning All,
There are a few reasons to open a PTO, no need to mention those, for me the
big question is the desiccant needed in civilian usage?
I agree - In fact I would make it a point not to replace the original plastic
dessicant bag in an R-388, R-390 or R-390A PTO. The plastic bag is probably
brittle and could break making a mess inside the PTO as described. The factory
never intended for the chemical to last 40-50 years or more. The PTO has long
since been exposed to air migrating into it every time it heats and cools for
the last 40 years probably and it won't make any difference in performance to
try to replace the dessicant. Best to leave it out and avoid future trouble
and possible corrosion problems. 73 Todd WD4NGG
