Disassembling a Marlin Glenfield 30A action for cleaning and maintenance.
Field stripping the Action of a Marlin Glenfield 30A..
First visually make sure the weapon is unloaded by opening the action and checking the chamber and feed ramp for cartridges..
Leave the action fully open and lay the rifle on a clean flat surface such as a padded bench or table..
Using a good quality tight fitting flat blade screwdriver remove the lever pivot screw..
Pull the lever free of the bottom of the action and out of the frame..
Grasp the bolt and pull it rearward out of the frame..
The EXTRACTOR is a single stamped piece of spring steel that grips around the bolt and is removed by carefully prying it free..
Clean the bolt with solvent and a small brush then wipe dry and apply a small amount of heavy gun oil or petroleum jelly to the machined depression in the bolt where the extractor grips it and also to the new extractor..
Push the new extractor onto the bolt until it is seated completely then check for proper clearance of the claw to the bolt face by placing a spent shell on the bolt face..
If the claw does not grasp over the rim of the shell and hold it in place over the bolt face try to wiggle the extractor at the point it clips onto the bolt to make sure it is seated properly..
If this fails to achieve the proper clearance you may need to remove the extractor and file the claw until it grasps the rim of the shell correctly..
Wipe away any excess lubricant and apply a light coating of gun oil to the entire bolt..
Clean the inside of the frame with gun solvent and a brush taking care to clean around the ejector lever in the back of the action.. You can remove the ejector by simply pushing on its post which is visible at the rear outside flat opposite of the ejection port.. Wipe dry and lightly lubricate all contact surfaces inside the frame..
Reassemble the bolt back into the frame the same way it came out and reinsert and attach the lever with the pivot screw..
