Thank you for the Special Tool making DIY.
I suggest these changes to your instructions:
For those needing or wanting instructions.
#0. Take pictures for reassembly and routing, BEFORE work begins.
#1. Pull throttle linkages off and out of the way.
#2. Remove the STEEL Injector lines from injectors and injection pump, flip the line set up side down, cover the line ports to protect against dirt/grit, and set aside.
#3. Cover the injection pump delivery valve ports against grit/dirt.
#4. Remove the injectors.
#5. Remove the injector heat shields (I used an old dental pick to remove the shield).
#6. Remove glow plugs, brace the wire harness connector so it does not twist off.
#7. Remove prechamber collars.
#8. Screw tool into prechamber and extract using slide hammer (Mine took about 10 smacks each, some prechambers have been known to require heavier force).
#9. WARNING: Make sure prechamber seal ring is also removed.
#10. Clean out any carbon / soot / dirt, use a vacuum cleaner with a wide bore drinking straw taped to the nozzle for reaching into the cylinder.
#11. WARNING: You MUST install a NEW prechamber seal ring every time the prechamber is removed, this is a single crush seal…
OM617 part numbers are:
Standard seal ring MB# 6150170060
Repair size I; 2.3mm MB# 6150170160
Repair size I; 2.6mm MB# 6150170260
Repair size I; 2.9mm MB# 6150170360
#12. Using a good used or new prechamber, thread tool into prechamber and tap into place firmly.
OM617 prechamber number is:
MB# 6170100352
#13. Install new collar
OM617 prechamber collar number is:
MB# 6150170003
#14. Install new glow plugs, WARNING/DANGER: you can break the tapered seat in cylinder head with excess force.
#15. Install a NEW heat shield. WARNING: You MUST install a NEW heat shield every time the Injector is removed, this is a single crush seal…
#16. Install wires onto glow plugs. WARNING/DANGER: This is an electric connection, the eight millimeter nut should be tightened with a wrench, and final torque is applied using one finger tip = any more force will damage or break the electrode = destroy your new glow plugs.
#17. Install STEEL injector lines, and looped fuel return hoses.
#18. Install throttle linkage.
#19. Prime the fuel system one hundred strokes.
#20. Start the engine.
#21. Use 50/50 solution of dish soap/water to inspect for prechamber combustion leaks.
