TM 9-2320-361-24-1 0021 00 0021 00-4 GENERAL MAINTENANCE PROCEDURES (Contd) GENERAL REPAIR PROCEDURES (Contd) 5. Replace all bent and stretched studs. Repair minor thread damage with a thread die. Use the following methods to replace studs having stripped or damaged threads: a. Use a stud remover to remove studs. Back studs out slowly to avoid heat buildup and seizure, which can cause stud to break off. b. If studs break off too short to use a stud remover, use a stud extractor to remove studs, or use welding method. c. Broken studs can be removed by welding a nut or bar stock to stud and removing with wrench. NOTE • Standard studs may have a coarse thread on one end and a fine thread on the other end. The coarse thread end is installed in the aluminum casting. The short threaded end goes into the casting. Studs having coarse threads on both ends are used in some applications Refer to TM 9-2320-361-24P for correct part numbers. • Replacement studs have a special coating and must have a small amount of antiseize compound applied on threads before stud is installed. Install replacement stud slowly to prevent heat build up and snapping off. 6. Use puller to remove gears. Remove minor nicks, burrs, or scratches on gear teeth. If keyways are worn or enlarged, replace gear. 7. Replace bushings when bushing and bushing-type bearings seize to a shaft and spin in the bore, also replace the associated part. CAUTION Be careful not to damage casting or adapter bore when removing oil seals. 8. Remove oil seals by pressing or prying out. Use proper seal replacement tool to install new seal in bore. GENERAL ASSEMBLY PROCEDURES When assembling components, follow these rules to ensure proper operation of vehicle: 1. Cleanliness is essential in all component assembly operations. Dirt and dust, even in small quantities, are abrasive. Parts must be cleaned as specified and kept clean. Wrap or cover parts and components when assembly procedures are not immediately completed. 2. Coat all bearings and contact surfaces with operating oil (axle oil for axle parts, transmission oil for transmission parts, etc.) to ensure lubrication of parts during initial operation after repair. 3. Use new gaskets and preformed packing during assembly of all components. END OF WORK PACKAGE
