1.0 INTRODUCTION
The patented LORD J-28348-64 MWD Tool Axial Isolator is designed for service in air, foam, or mud drilling operations.
Its use and maintenance requirements are summarized in this document.
2.0 FUNCTION
The LORD J-28348-64 MWD Tool Axial Isolator (herein referred to as the Isolator) is designed to protect the sensitive
electronics in an MWD string by isolating these components from broad frequency vibrations. The isolator will also
attenuate shock inputs.
3.0 ASSEMBLY INTO MWD/LWD TOOL STRING
3.1 Mechanical
The Isolator has been designed to be assembled and disassembled to MWD String with 1-7/8 inch (1.875 inch) diameter
friction wrenches and/or friction vise.
Figure 1: 1-7/8" Friction Wrench
3.2 Pressure Conduit
The Isolator is designed to be used as fluid conduit for use with a pulser.
3.3 Location in MWD String
The Isolator has been designed to support the MWD string and be located directly between the pulser driver and lower
end.
Figure 2: Axial Isolator Location in MWD String

UM1004 | MRO-00011 05/21 Rev.0 DCO-016875 5
4.0 OPERATING PARAMETERS
4.1 Maximum Operating Conditions
The Isolator was designed for the operating conditions shown in Table 1.
Table 1: Maximum Operating Conditions
Temperature
350°F maximum
Pressure
N/A
The Isolator can withstand temperatures of 350°F and beyond; however, extended periods of exposure to this extreme
condition should be avoided. Prolonged exposure to consistent elevated temperatures (>300°F) will accelerate the
degradation of the elastomer package, reducing the elastomer’s overall useful life. Elastomer kits rated for high
temperature use are available, please contact your Parker LORD representative for details.
The Isolator has no pressure rating limitations as it is pressure compensated with the downhole environment.
4.2 Maximum Static Loads
The maximum loads for the Isolator are shown in Table 2. Note that the recommended assembly torque is 250 ft-lb, well
below the maximum torque.
Table 2: Maximum Static Loads
Maximum Torque
400 ft-lb
Axial Load (Fishing Load)
5,000 lb
4.3 Explosive Decompression
The Isolator was not designed to function following an explosive decompression event. If any such event should occur,
the Isolator should be removed from use, disassembled, assessed for damage, and any damaged components replaced.
5.0 PARTS LIST
The Isolator consists of the items shown below, in Table 3. An Illustrated Parts List (IPL) is shown in Figure 3, Section 8.0.

7.0 RECOMMENDED SERVICE KIT STOCK
Parker LORD recommends that certain service kit items be put in stock by the users of the Isolator to facilitate quick repair
or replacement of wear items. This section will detail the recommended kits and quantities that should be kept on hand.
Quantities of each kit are given per number of Isolators in service (see Table 5). For example, for each Isolator in service,
five (5) Redress Kits are recommended to be kept in stock. For some lower wear items, a single kit can support several
Isolators.

9.2 Overall Length (OAL) Inspection [Shoulder-to-Shoulder]
The nominal starting length of the Isolator is 36 ± 1/16 inches long when measured shoulder-to-shoulder as shown in
Figure 6. Between runs, the length can be checked using the below method. When the OAL falls near or below the
minimum, the Isolator requires a full elastomer replacement, Level II Service.
Table 9: OAL Shoulder-to-Shoulder
Nominal
36 inches
Minimum
35 inches
The anti-rotation feature should also be checked before the Isolator is run below the rotary table. To do so, attempt to
manually rotate the Isolator. If the part rotates, tear down the Isolator and ensure pins are installed and are in working
condition.
