Page 4: Introduction
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. 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. -
Page 5: Operating Parameters
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. -
Page 6: Redress Kits
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. -

Page 9: Overall Length (Oal) Inspection [Shoulder-To-Shoulder]
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. -
