Annual Maintenance
Whenever the equipment is down for general maintenance
or service, recheck the tightening torque of flange
fasteners. Tighten fasteners if necessary. For extreme
or unusual operating conditions, check coupling more
frequently.
Part Descriptions
Part descriptions are shown below. In addition, all coupling
parts have identifying part numbers. When ordering parts,
always SPECIFY SIZE and TYPE of hub, and part number.

Figure 7 — BASIC TYPE 6 HUB REMOVAL EQUIPMENT
(1)
Hydraulic hub puller.
This is a hydraulic ram that is
threaded into the puller plate (9).
(2)
Low-pressure pump.
The pump should have a 5000
psi (34.5 MPa) maximum pressure rating.
(3)
Low-pressure gauge.
The gauge should have a large
enough face for accurate readings, with a maximum
pressure rating of psi 5000 psi (34.5 MPa).
(4)
Low-pressure flex line and fittings.
At 5000 psi
(34.5 MPa), this line can be flexible, which makes
it more convenient when hooking up the system.
Appropriate end fittings and a gauge mounting
snubber are also needed.
(5)
High-pressure pump.
The pump should have a
40,000 psi (276 MPa) maximum pressure rating.
(6)
High-pressure gauge.
The gauge should have a
large enough face for accurate readings, with a
maximum pressure rating of 40,000 psi (276 MPa).
(7)
Rigid high-pressure line and fittings.
At 40,000
psi (276 MPa), a rigid steel, high-pressure line with
special high-pressure connectors are mandatory.
A high-pressure tee and at least 2 high-pressure
elbows are needed to mount the gauge and for
routing the line.
(8)
High-pressure valve.
This valve is used to shut the
pressure off at this end of the hub as it comes off
the shaft.
(9)
Puller plate.
This plate is threaded in the center to
accept the hydraulic ram. It also has holes drilled in
it to line up with the tapped puller holes in the hub
(See Table 3).
(10)
Puller rods.
These rods are usually threaded full
length. They connect the hub to the puller plate
(Reference Table 3 for thread size).
(11)
Nuts.
These nuts position the puller plate.
