# Reassemble the Reaction Nut

When you receive a new puller bar replacement kit, the puller bar and reaction nut will be correctly positioned and locked together with a small setscrew. Make a note of the position of the puller bar and reaction nut position, particularly the fact that the top face of the reaction nut is “flush” with the thread shoulder of the puller bar . The reaction nut needs to be taken apart and eventually reassembled.

1. Remove the small setscrew locking the reaction nut to the puller bar.

2. Feed the puller bar up through the load cell assembly

3. Reassemble the reaction nut onto the puller bar taking care to screw the reaction nut down to exactly the same position as when the kit was delivered. When assembled the reaction nut should rest on the upper piston. Ensure the top face of the reaction nut is “flush” with the thread shoulder of the puller bar . Once in the correct position reassemble the small set screw, locking the reaction nut and puller bar together.
