After removing cap screws there will be a small amount of debris on the screws. Ensure that any loose debris is removed from inside and the face of the cylinder barrel.

1 To prevent as much fluid loss as possible, turn your steering wheel to hard over on the gland side that you are working on, i.e. Por t side gland, turn steering wheel to por t side.

2 Disconnect tubing from cylinder fitting and remove fittings from end gland.

3 Loosen the two socket cap screws securing the gland to the cylinder barrel (Item 1) using a 5/32" Allen Driver. DO NOT remove the screws at this time. Use a 5/8" box-end wrench to hold the cylinder rod nut that is on the same end as the gland that is being removed.
