Product Details

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

  • Remove the intake manifold
  • Remove the glow plugs 
  • Remove the mutli-spline 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.
