Mortise cylinders have always been at the foundation of Medeco's product line. In fact, 10 Series mortise cylinders were the first to roll off the assembly line when Medeco opened its doors and started production in 1968. Although the overall mortise cylinder design has seen very little change...

If you are master pinning this cylinder, load the master pins in the cylinder before the top pins. In a master keyed situation, the top pin number will be a number that equals the total of the bottom pin and the master wafer added together.
If you are using a mushroom driver, make sure the cap is pointing down toward the bottom pin.
Step 7. After the top pin is loaded, test the key to ensure that it operates. If the cylinder is master pinned, test all keys that were designed to operate this cylinder.
If the key works, repeat steps 5 – 7 for the remaining pin chambers until all pin chambers are loaded with the necessary bottom and top pins. If the key does not work, recheck the pins used in that pin chamber.
Step 8. Once all of the pin chambers have been loaded with the proper bottom and top pins and the cylinder has been tested with a key, slowly remove the key. Load the tumbler springs.
Step 9. Once the tumbler springs have been loaded, you can begin to cap each pin chamber. A 5/64" Allen wrench is required to secure the Allen set screws in each pin chamber. The set screws should be lightly snug and be deep enough to clear the mortise cylinder threads. If the set screws are over tightened, they may be difficult to remove. This may also cause too much pressure on the pin stack and the cylinder will be difficult to operate. Once the Allen set screws are secured into place, the cylinder can be removed from the holding fixture. The cylinder is now ready for installation. It is not necessary to use Lok-tite on the set screws.
