(CAN) UPON TAKEOFF FROM AIRPORT,  MLG SELECTED UP, BUT THE INTRANSIT LIGHT DID NOT GO OFF.

HYD SYS PRESSURES WERE CHECKED & FOUND TO BE WEAK, HYD POWER PACK WAS REPLACED WITH AN OVERHAUL UNIT, MULTIPLE GEAR SWINGS WERE PERFORMED AND THE AIRCRAFT WAS GROUND RUN AND HYD PRESSURES WERE CHECKED SERVICEABLE.  THE AIRCRAFT SUBSEQUENTLY PERFORMED A TEST FLT WITHOUT GEAR TROUBLES.
