This bolt belongs in the position assigned to its original number and length. It is not a universal replacement for every M12 fastener around the transmission case.\u003c\/p\u003e\u003cp\u003eThe 50 mm length distinguishes this bolt from the longer M12 fasteners used elsewhere in the same case attachment. Returning each fastener to its designated position helps avoid insufficient thread engagement or bottoming in a different hole.\u003c\/p\u003e\u003ch3\u003eCommon reasons to replace\u003c\/h3\u003e\u003cp\u003eInspect the bolt during transmission removal, clutch service or other work that separates the transmission case from the engine. Replace damaged threads, a rounded drive head, corrosion affecting the bearing surface or a visibly bent fastener. Renew removed fasteners whenever the applicable factory procedure requires it.\u003c\/p\u003e\u003cp\u003ePrevious repairs can leave a mismatched bolt, an incorrect length or a damaged head that prevents proper installation. Verify the original number and mounting position before ordering. A bolt that starts in a threaded hole is not proof that its length and bearing arrangement are correct.\u003c\/p\u003e\u003cp\u003eInspect the joint if a fastener is missing or loose. Determine why it became loose and check the surrounding case, threads, locating features and other hardware. A replacement bolt cannot repair a cracked housing, stripped hole, damaged locating sleeve or an incorrectly aligned transmission.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eUse the factory removal and installation procedure for the vehicle's exact engine and manual transmission. Support the drivetrain with appropriate equipment before disturbing the connection. Identify each fastening position and preserve the position information for bolts of different lengths.\u003c\/p\u003e\u003cp\u003eInspect the mating faces, threaded mounting point and locating features before assembly. Address damage or contamination using the prescribed repair procedure. Do not force a bolt into damaged or misaligned threads.\u003c\/p\u003e\u003cp\u003eAlign the transmission correctly with the engine before tightening the case fasteners. Do not use this bolt to pull a separated or misaligned transmission into position. Correct alignment is particularly important when the transmission has been removed for clutch work.\u003c\/p\u003e\u003cp\u003eStart the bolt by hand in its assigned position. Use a correctly fitting twelve-point socket and keep it square to the head. Stop if the bolt binds before seating and recheck the hole, alignment and part selection instead of applying more force.\u003c\/p\u003e\u003cp\u003eFollow the factory tightening sequence and the exact torque or angle requirement for this fastening position. No universal torque value applies to every transmission case bolt. Follow the specified thread preparation and replacement instructions; do not add lubricant or thread locking compound unless prescribed.\u003c\/p\u003e\u003cp\u003eFor replacement transmission cases or modified drivetrain installations, confirm the hardware specification independently. This original fastener's confirmed factory application does not establish compatibility with every conversion or aftermarket component.\u003c\/p\u003e\u003cp\u003eCheck that all required case fasteners and locating components are present before completing the surrounding service work. Perform the prescribed final checks for the repair.
