The Poo service handbook mandates a blowtorch!
Quote:
"The recommended source of heat is the use of propane
gas, and can be obtained at most commercial hardware
stores."
Also:
"Bonded components must be removed, cleaned,
and re-bonded if the adhesive is subjected to
temperatures above 300° F (149° C)."
In my experience, removing chain cases, it takes a good amount of grilling due to the heat dispersion of alu.. Heated enough it makes a pop and snaps loose (due to glass beads mixed in the adhesive)
