Tamperproofing-equipped boost compensator cover installation procedure
(A) After adjusting the boost compensator, tighten the bolts to remove the heads.
(1)Before adjusting the governor and the boost compensator, tighten the screw to the specified torque.
(Tightening torque T = T1 maximum)
(2)After adjusting the governor and the boost compensator, tighten to the specified torque to break off the bolt heads.
(Tightening torque T = T2)
----------
T1=2.5N-m(0.25kgf-m) T2=2.9~4.4N-m(0.3~0.45kgf-m)

PROBLEM
All 20R-0476 Injector Assemblies in dealer parts stock need to be inspected for the date code. 20R-0476 Injector Assemblies that have a date code of D08M07Y15P47 need to be removed from dealer parts stock. These injector as may have a nozzle assembly marked 2645K015 which is not correct. (Image1 = Incorrect) The correct nozzle assembly should be marked 2645K016. (Image2 = Correct) These two nozzles are not interchangeable.
ACTION REQUIRED
Inspect the date code on all 20R-0476 Injector Assemblies in dealer parts stock. 20R-0476 Injector Assemblies that have a date code of D08M07Y15P47 need to be removed from dealer parts stock.
