I recommend however to learn replacing the end stud to the arm. I found it unnerving as well, and even opened a thread here without much solution, until I realized that using angled tweezers makes the job much easier. You can practice at will on the damaged hairsping.

Follow the instructions is the data sheet which has pictures. After placing the stud in the right position I recommend you continue pressing it in with the curved tweezers until it clicks. If you use another tool the contact is not secure and if if slips it can destroy the HS.

Yes will do.... thanks for your support I will be working on it this weekend.

 

Hello - sorry to resurrect this old thread, I have to also replace a complete balance assembly from an NH36A to the 4R36A.  How did your repair turn out?  This is the new thread I posted about my next nightmare repair. :)
