Remove the magazine and cycle the action. Put safety "on-safe". Drift out the two crosspins in the receiver. Move trigger group forward, down and out. This assembly can be cleaned as a group with aerosols such as Gun Scrubber.

Remove the large bolt in the front of the forend, then the forend can be slid forward and off. There is a large roll-pin which secures the action tube to the gas tube housing. USING A ROLL-PIN PUNCH, drift out the pin. Using a standard type punch will damage the pin. Bring the bolt to the rear and hold it there. Slide the bracket you just drifted the pin out of toward the rear and tip the action tube downward and then forward. DO NOT RELEASE THE BOLT or you will damage the gas tube. Slowly allow the bolt to move forward as you remove the action tube. You can now remove the recoil spring carefully (it is under tension).

The barrel is held on by the large nut at the bottom front of the receiver. Be exceptionally careful to match the wrench to the nut (there are special tools available, and they should be used). The nut removes counter-clockwise as viewed from the front. Remove the forend stabilizer spring mounted behind the nut as well.

Move the bolt halfway back to the rear again, then move the barrel forward out of the receiver. Move the bolt back forward, then turn the barrel 90 degrees and remove it from the action bars.

The bolt handle is retained by a small cross pin. You will have to position the ejection port cover and bolt just so to see it. It is drifted downward for removal, then remove the bolt handle. This allows the bolt and action bar assembly to be removed through the front of the receiver.

When cleaning, pay attention to the gas ports in the barrel (there is a special tool available).

Hello,

Thank you for posting details Rem 7400 disassembly directions. I got as far as trying to remove the pin that secures the bolt handle to the bolt, but I cannot seem to get pin to come out. I've bent three punches doing it. Is there a trick to it or is it unusually tight to remove? - Thanks

First make sure the bolt is lined up with the notch in the receiver so you can get a punch properly allined to it. Punch the pin out from the top so it drops out of the bottom of the gun. The pin is splined so it only goes one way. If one way won't come out, try the other way. If the gun was ever taken apart before its possible the pin is in backwards.

ok where did he go

If you are bending punches , check your angle of attack , that pin wants to go downward not to the side . Generally a good pop with the proper starter punch will move it . A drill bit shank of the proper diameter makes a good punch for this job . There's no notch in the receiver , but there is one in the dust cover . It's a tapered pin and will only go in one way .
