ELECTROMAGNETIC COUPLlNGS SERIES 30900
Running-in is required to obtain the desired ratad torque values of
electromagnetic couplings. Running-in is carried out by engaging
and disengaging clutch at high speed several times with the pump in
During assembly, make sure that there are no oil or grease traces on
pulley surfaces whith must be completely clean.
When assemblying electric clutches with front driving fl ange, check for
proper coupling alignment, but do not exceed rated torque because
this would cause slippage of contact surface. This stage must not last
more than 5 secs since coils could burn.
