Action

1 First apply an activator to the con-
tact surfaces.
2 Then apply new flange sealant to the
corresponding contact surfaces.
Note
The activator must be used to harden the
flange sealant.
Fit two guide pins in opposite holes in the
wrist.
Tip
Lubricate the guide pins with some grease
to make the wrist slide better.
