Sealing Seams cont'd

(4) Next, remove the bolts which are holding the damaged wedge gasket in place. Remove the damaged

gasket and replace it and the bolts. Be sure to keep the new gasket shoved back against the thick end. A rolled thread

of sealing putty (1/s inch diameter - 11/2 inch long) should be placed behind the thick end of the gasket in order to insure

a seal. Avoid smearing putty on the wide, flat surface of the gasket as this will act as a lubricant and could cause the

wedge gasket to spread and split when the chime bolts are tightened.

(5) Gradually remove the wedges in reverse order. They can be extracted from the chime seam by tap-ping

them back and forth sideways with a hammer while pulling on them with a pair of pliers. Page, 10-1.Paragraph 10-
