Tightening torques for banjo screws as per MTN 5183–2 standard This standard applies to banjo screws as per MMN 223 and N 15011 sealed with sealing ring DIN 7603-Cu MMN 223 (4 flow holes)
N 15011 (3 flow holes)
Tightening torques MA are given for banjo screws made of steel (St) with surface protected by a phosphate coating and oiled or galvanised and for banjo screws made of copper-aluminium alloys. Thread and mating faces beneath heads must be coated in engine oil prior to assembly. An assembly tolerance of + 10% of the table values is permitted for unavoidable deviations of the tightening torque from the table value during the tightening process – e.g. resulting from inaccurate readings and overtightening during assembly.
