Z27AG Shifter Linkage Repair Bracket








So back in 2011 when i installed my new clutch i broke the shift linkage bush. No surprise here as they are a crappy design and can tear when removing them.
Just the other week mine started to pop off. Looks like the balljoint cup wore out? or became loose over time.







I did spray it with WD40 a while back, wondering it that was the cause of the bush getting a bit too slippery and popping off.





So i designed a little clamp that can go over the ball stud but slide around on itself to a narrower part of the clamp. This allows it to hold onto the ball stud.

If this doesn't work i am considering a heim joint / rose joint.
Angle joint - consisting of ball stud and ball journal
Female Rod end with spherical plain bearing




Round end ball pressure screw - replace the current ballstud on the gear shifter

rod ends are available with slotted shank and compressible threaded section or with a "welding shank" i.e. a shank suitable for welding to another component.

Rod End Bearings, also known as a heim joint (N. America) or rose joint (U.K. and elsewhere), are a mechanical articulating joint. od End Bearings are used on the ends of cylinders, linkages, rods, and shafts to take up misalignment between connected parts. They consist of a spherically-shaped inner ring and a cylindrical bore for mounting on a shaft. Rod End bearings attach to rods and shafts via a male stud with external threads or a female housing with internal threads. Right-handed threads tighten in a clockwise direction and are the most commonly used type of thread. Left-handed threads tighten in a counterclockwise direction and must match the mating part.

Rod end bearings differ in terms of dimensional specifications and special features. Dimensional specifications include design units, bore diameter, major diameter, bearing thickness, housing diameter, overall length, and thread length. English design units include inches (in) and fractions of an inch. Metric design units include millimeters (mm) and centimeters (cm). Bore diameter is the inner diameter (ID) of the bearing bore. Major diameter is the nominal diameter to the top of the threads. Bearing thickness is the length through the bore. Housing diameter is the outside diameter (OD) of the bearing housing. Overall length is the distance from the top of the housing to the end of the shank. In terms of special features, some rod end bearings are self-lubricating or include a lubrication port. Others are corrosion-resistant or equipped with PTFE seals.
