On theFront Flange (FF) and Front Flange Extra(FFX) Mounts, in these sizes, the roundretainer shown above is not used. The tierods thread into the flange, and the fla n g eserves as the rod gland retainer. Hence, inthese sizes, the gland cannot be removedwithout loosening the tie rods. The basiccylinder dimensions shown above do notchange. See drawing A.On the Front Head Flange Mount (FHF), inthese sizes, the retainer is the samerectangular size as the head. Tie rodsthread into the retainer and the retainerholds in the packing gland. Hence, in thesesizes the gland cannot be removed withoutloosening the tie rods.
