C3882) 8 Remove the pivot pins using a brass drift punch and hammer. 9 Remove the quick - tach from the loader boom arms. Extend tilt cylinders C3880 C3881 Installation Upon installing the quick - tach to the loader boom arms: 1 Make sure all pivot pins and bushings are in good condition. Do not reuse worn parts.
