UPDATE: This yellow slide hammer is no longer available. You can purchase our new silver Version 4 model. See related products below. This is one of the tools you will need to remove stubborn pre chambers. NOTE: You will also need the collar nut removal tool to get the slotted nut out of the head BEFORE you can remove the pre-chamber with the slide hammer. (see related products below) This slide hammer puller includes a special fine thread insert that is installed into the pre-chamber and the slide hammer is then securely attached to that insert. Repeated impacts using this reinforced heavy slide hammer will slowly remove the pre-chamber from the head. This action works to slowly pull the pre-chamber out of the head.
