Narrative:
One of our 200 series dash 8's ferried to our base for an engine change, propeller change, and sheet metal repairs. Our base here in ZZZ normally only works on 100 series dash 8's. A crew removed and replaced the PW123 engine but did not install the propeller nor did they rig the engine controls. Another mechanic and I were told by our supervisor to install the propeller and to get the aircraft ready for an XX00 departure. The propeller installation and engine rigging was complied with and inspected in accordance with the maintenance manuals. The event was caused by the nacelle mounted control rods being installed on the wrong side of the levers at the engine's fuel controller. The correct side was opposite of what was in the manual. The main contributing factors were that the manuals were incorrect and not specific, lack of training, and a poor turnover from the crew that removed and replaced the engine. The situation was discovered during a revenue flight on the next day when the crew reported that the power and condition levers for that engine bound up. The crew was able to free the levers and continued and completed their flight.

Title: A DH8-200 RPTED ENG CTLS BINDING ON A RECENTLY REPLACED ENG. FOUND MAINT MANUAL FOR ENG FUEL CTL RIG FOR MODEL 200 INCORRECT.
Narrative: ONE OF OUR 200 SERIES DASH 8'S FERRIED TO OUR BASE FOR AN ENG CHANGE, PROP CHANGE, AND SHEET METAL REPAIRS. OUR BASE HERE IN ZZZ NORMALLY ONLY WORKS ON 100 SERIES DASH 8'S. A CREW REMOVED AND REPLACED THE PW123 ENG BUT DID NOT INSTALL THE PROP NOR DID THEY RIG THE ENG CTLS. ANOTHER MECH AND I WERE TOLD BY OUR SUPVR TO INSTALL THE PROP AND TO GET THE ACFT READY FOR AN XX00 DEP. THE PROP INSTALLATION AND ENG RIGGING WAS COMPLIED WITH AND INSPECTED IN ACCORDANCE WITH THE MAINT MANUALS. THE EVENT WAS CAUSED BY THE NACELLE MOUNTED CTL RODS BEING INSTALLED ON THE WRONG SIDE OF THE LEVERS AT THE ENG'S FUEL CTLR. THE CORRECT SIDE WAS OPPOSITE OF WHAT WAS IN THE MANUAL. THE MAIN CONTRIBUTING FACTORS WERE THAT THE MANUALS WERE INCORRECT AND NOT SPECIFIC, LACK OF TRAINING, AND A POOR TURNOVER FROM THE CREW THAT REMOVED AND REPLACED THE ENG. THE SIT WAS DISCOVERED DURING A REVENUE FLT ON THE NEXT DAY WHEN THE CREW RPTED THAT THE PWR AND CONDITION LEVERS FOR THAT ENG BOUND UP. THE CREW WAS ABLE TO FREE THE LEVERS AND CONTINUED AND COMPLETED THEIR FLT.
