⚠️ Common Signs of Failure

• Mating housing misalignment
• Guide sleeve loose or seized in the block
• Visible wear, cracking or deformation
• Loose, damaged or corroded mounting
• Loss of the assigned system function

🛠️ Service Notes

• Check the sleeve and the part that runs in or on it for scoring, ovality, corrosion and pick-up; renew both if either is worn, since a worn pair will never locate correctly
• Clean the bore and the housing before fitting and remove any burrs or corrosion that would stop the sleeve going fully home
• Press or drive the sleeve in square with a tool that bears on its end face rather than on its bore or edge, and seat it fully against its shoulder
• Where the sleeve carries lubricant or a seal, make sure any oil hole lines up, and renew the adjacent seal or O-ring at the same time
• Check that the shaft or fastener it guides moves without binding once the sleeve is home
