There is a construction variance in the 1 1 / 8 ", 1 1 / 2 ", 2"
bores, the 2 1 / 2 " bore with a 1 3 / 8 " or a 1 3 / 4 " rod, and in the
3 1 / 4 " bore with a 2" diameter rod. On the Front Flange
(FF) and Front Flange Extra (FFX) Mounts, in these
sizes, the round retainer shown above is not used. The
tie rods thread into the flange, and the flange serves as
the rod gland retainer. Hence, in these sizes, the gland
cannot be removed without loosening the tie rods. The
basic cylinder dimensions shown above do not change.
On the Front Head Flange Mount (FHF), in the 1 1 / 8 ",
1 1 / 2 ", the 2 1 / 2 " bore with a 1 3 / 4 " rod, and the 3 1 / 4 " bore
with a 2" rod, the retainer is the same rectangular size
as the head. Tie rods thread into the retainer and the
retainer holds in the packing gland. Hence, in these sizes
the gland cannot be removed without loosening the tie
rods. Dimensions for these sizes of the FHF mount
cylinders can be obtained from the Front Flange Mount
(FF) charting. Mounting bolts will clear through both the
flange (FF dimension) and the head (G dimension).
