    Hi All,
    We have a broken bolt of the circumferential register assembly. This is one of the four bolts which is used to tight the cylinder.

    Any tips on how to take out the broken piece of the bolt which is struck inside?

    Regards,
    Abhi

    Have you tried an easy out? Also you need to give the guy that broke it off a good cuff to the back of the head!!! Dont let him be the one to extract the broken bolt. I would suggest that perhaps someone is tightening the bolts too tight and stressing the bolt to the point of failure. Shouldn't require more than say 30 to 35 ft lbs of torque on each of the bolts to keep the cylinder from moving.

    True, the bolt was tightened beyond limit.
    We successfully extracted it. The problem was the bolt was moving freely but the bolt head was not letting it come out or go in and fall. Just imagine a bolt with its thread free between a ring formed by your fingers but it's head unable to come out from the fingers or go in becaude there is a wall behind it.

    It was extracted by cutting it :).
