Mech-Tech CCU Operation & Maintenance Manual - 1911 Model 1) SAFETY ADDENDUM This is a safely addendum to follow page 1. Carefull reading of this manual will reveal that the bolt must be retracted before any attempt to remove the pistol lower unit. There can occur a unique circumstance where a cartrige gets stuck in the chamber and the bolt cannot be retracted. The stuck cartridge may not be seated fully into the chamber and this will prevent the fireing of the CCU because the bolt is not fully forward.

muzzle end of the housing. Be certain that the 1911 lower unit is in full contact with the CCU housing when the ‘rails’ are in their correct opening and only then push the lower forward. Assembly of the 1911 lower into the housing may be easier with the whole thing upside-down. Be cautious to remember that unintentional release of the CCU bolt during assembly can injure a finger! A word here may be helpful as to senses of direction as used in this manual.

3) Maintenance The CCU does not ‘field strip’. The main areas of concern are lubrication and cleaning. The cleaning of the barrel bore and chamber is performed using the same techniques as with other firearm systems. Use a cleaning rod and a bore brush followed by rod and patch. Use any of the commonly available bore solvents for this. The barrel is stainless steel and does not require any lubrication after cleaning. Lock back the bolt in the open position while cleaning the bore.

FIG. 9 SAFETY SPRING BOLT CHANNEL SUBASSEMBLY BOLT INSERT BOLT CHANNEL 13 (Do not use the springless bolt handles with a housing designed for the spring loaded bolt handles and vice versa.) The next step in the CCU disassembly is to remove a total of 8 SHCS’s - 4 on each side of the housing at the front. The heads of these 8 screws also serve to locate the plastic foregrip. You will need a 9/64” hex wrench. The screws are 8-32 SHCS’s which are 5/16” long. Do not substitute screws of a different length.

Keep the right thumb firmly over the post so as to prevent the recoil spring from leaving the post. Now separate the bolt from the barrel by about 3 inches. Do this by pulling the assemblies apart along an axis parallel to the barrel. You will notice that the recoil spring has stretched. Carefully tilt the barrel, using your right thumb as the approximate pivot point, so that the portion of the barrel which is to the rear of the support moves out of the channel in the bolt.

RAIL MOUNTING THREADED STUDS MOUSETRAP SPRING 19 FIG. 10 When the extractor pivot pin is removed the extractor falls free. Note carefully how the extractor is oriented. The ‘claw’ faces inward. The extractor has two small holes at one end. The rear-most hole is larger and it is through this hole that the pivot pin must go when reassembling. The smaller hole just forward of the pivot pin hole is for the extractor spring.
