TRailing Arm Stud Alignment jig


Recommended Posts

Based on various repairs I made my own baseplate and new Studs.

M11 with 5/16". I did not want to deal with helicoils and stuff. Eventhough M11 x 1 can be considered "fine" thread, the increased diameter is more than sufficient to withstand required torque.

If required, I can supply the drawings for drilling and tapping.

I've seen numerous thread breakthroughs on the stud walls when they've been helicoiled, especially when the helicoil thread has been tapped in on a lean which coincides with the closest side, and that's where the tapping drill dia is only drill size for 5/16th UNC Helicoil is .328 thou (outer tapping size for the helicoil). This is 16thou MORE than the .312 (5/16th) hole required for a 3/8th UNC PARENT thread tapped into the alloy casting. Conveniently when the 5/16th UNF thread in the trailing arm strips it often leaves a hole of about the .312 thou dia there which accepts the 3/8 UNC tap nicely.
