0000001501 TAMPER PROOF

Test data 106676-2321
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)
----------

Timing setting
