Features/Benefits
-
- * Used to remove and install threaded gland heads on hydraulic cylinders.
- * Spanner wrench virtually eliminates chance of disengagement when removing or installing gland.
- * Eliminates damage to gland caused by hammering, welding, heating, or other destructive means of gland removal.
- * Removes glands where spanner wrench slots are in face or outside diameter of gland (each adapter works on a specific gland design).
- * Designed to pilot around cylinder rod (fits most sizes of cylinder rods).
- * Two wrench sizes for convenience: 9U-7868 for 25 to 80 mm (1.0 to 3.2 inch) rod diameter and 9U-7869 for 76 to 115 mm (3 to 4.5 inch) rod diameter.
- * Spanner wrench is held in place with cover and six adjustable screws (can be tightened so wrench will not disengage even when rod is at a downward angle).
- * Screws are fitted with nylon pads to protect cylinder rod (screws also center wrench on rod, making installation and removal on gland much faster and easier).
- * New plates can be designed and released as needed.
- * Handle is heat treated for additional strength and all parts are zinc coated to prevent rusting.
- * Used with 5S-6090 Sliding (T) Wrench Head, 5S-6089 Handle, 8T-9294 Torque Wrench or equivalent, 2P-8261 3/4 to 1 inch Adapter, and hydraulic cylinder repair stand.
- * Used to remove and install threaded gland heads on hydraulic cylinders.
NOTE: Cylinder barrels should be honed before assembling new parts into cylinder.

Adapter Plate Usage
Chart A will help determine which wrench matches a specific gland. The chart includes a list of each available adapter, the part number of the threaded gland, and the model of the machine. Use Chart A to select the adapter plate required for disassembly of the cylinder.
Adapter Plate Specifications
Chart B can be used to identify adapter plates or to determine if an adapter plate can be used on a gland not listed in Chart A. There are three styles of adapter plates as shown in the illustrations.
Style "A" Adapter Plate - Pins engage radially; counterbore surrounds outside diameter of gland.
Style "B" Adapter Plate - Pins engage axially; counterbore surround outside diameter of gland.
Style "C" Adapter Plate - Pins engage axially; no counterbore; plate and gland faces contact each other.
