Product Details

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. ( Please note color of our current to is silver not yellow).

Pre-chambers will need to be removed if damaged or if you need to replace the sealing ring under the upper lip of the pre-chamber. If you have a cylinder that continues to run roughly even after you have determined good compression and proper injector spray pattern - then you may have a problem with the pre-chamber itself. Once remove it is easy to inspect it for damage. Note sealing ring in the picture below:

IMPORTANT: To remove the pre-chamber with this slide hammer tool you will first need to remove the collar nut that holds it in place. This will require another special tool. If you don't already own this tool please see related products below to order this tool. 

Here is a picture of the collar nut remove from the head:

The fine thread adapter fitting included with the slide hammer is shown below. No other attachments are included.

 

No specific written or video instructions are included, but here is a summary of the steps required to perform this job:

  • Remove the injector hard lines and the injectors
  • Remove the glow plugs - DO NOT FORGET THIS - you will damage your pre chamber!
  • Remove the collar nut (special tool required not included here - see related below)
  • Install the fitting on end of our new model  slide hammer 
  • Tighten the threaded end of the slide hammer shaft down tight to the special fitting
  • Multiple upward hard hits of the sliding hammer will be required to pull the prechamber out of the head
  • Clean the prechamber thoroughly before reinstalling
  • Make certain prechamber is aligned properly when tapping it back into the head

NOTE: If you remove the valve cover and gasket you can use heat from a good electric heat gun to heat the head slightly to aid in removal and replacement of the pre-chamber.
