Variances in Construction –
Tie Rods Extended Mounts
There is a construction variance in the
1
1 / 8 ", 1 1 / 2 " and 2" bores, and the 2 1 / 2 "
bore with a 1 3 / 8 " and 1 3 / 4 " diameter
rods, and the 3 1 / 4 " bore with a 2"
diameter rod. The round rod gland
retainer is not employed on those sizes.
A square retainer, the same square size
as the head, is used.
On the FX and BX mounts, the retainer
is secured by tie rod nuts and the rod
gland cannot be removed without
loosening the tie rods.
On the RX and NX mounts, the retainer
is secured by retainer screws that thread
into the head and the rod gland can be
removed without loosening the tie rods.
Variances in Construction –
Double Rod End Cylinders
There is a construction variance in the
1
1 / 8 ", 1 1 / 2 " and 2" bore sizes, and the
2 1 / 2 " bore with 1 3 / 8 " and 1 3 / 4 " diameter
rods, and the 3 1 / 4 " bore with a 2"
diameter rod. The round rod gland
retainers shown on the adjacent page
are not employed on these sizes. Square
retainers, the same square size as the
head, are used instead.
Side Flush (SF), Side Lug (SL),
Centerline Lug (CL), Trunnion
Front (TF), and Trunnion (T)
Mounts – The rod gland retainer on
one end is secured with retainer screws
that thread into the head. On that end,
the rod gland can be removed without
loosening the tie rods. On the opposite
end, the retainer is secured by tie rod
nuts and the rod gland on that end
cannot be removed without loosening
the tie rods in these sizes.
End Lug (EL) Mount – The lugs serve
as nuts on both ends on the bottom two
tie rods to secure the square rod gland
retainers and tie rod nuts are used on
both ends on the top two tie rods for
that purpose. The rod gland cannot be
removed without loosening the tie rods
in these sizes.
Front Head Flange (FHF) Mount –
A rectangular retainer, the same size as
the head, is employed on the mount end
and a square retainer, the same size as
the opposite end head, is used on the
other end. The tie rods thread into the
retainer on the mount end and tie rod
nuts are used on the opposite end.
Neither rod gland can be removed
without loosening the tie rods in these
sizes. Note that when mounting,
mounting bolts must be long enough
to clear through both the head (G dim.)
and the retainer (FF dim.).
Front Flange (FF) and Front
Flange Extra (FFX) Mounts –
In addition to the sizes mentioned
above, in these mounts the construction
variance also applies to the 4" bore with
a 2
1 / 2 " diameter rod, and the 5" bore
with a 3 1 / 2" diameter rod. The tie rods
thread into the flange on the mount
end and the flange retains the rod gland.
On the opposite end, a square retainer,
the same square size as the head, is
employed. It is secured by the rod
nuts. Neither rod gland can be removed
without loosening the tie rods in these
sizes.
