Thanks for posting, Sandeep. I've never personally worked with this kind of guide, but if it works like similar parts then it should be held in by those tabs you see sticking out of the housing. You will need to firmly work the old one out using needle nose pliers; there's no trick to this, it just takes patience. You can then insert the new one in the same slots where the old one went.
