Narrative:

During preflight; we were confronted with several issues; first of which was a hydraulic pump (adp) that was inoperative and on MEL. This restr our runway allowable takeoff weight and slowed our gear retraction time appreciably. In addition; flight control sent us 2 flight plan updates revising our block fuel. Since we were too heavy to depart from the usual runway (25L); we were told we would use runway 25R and a different departure procedure. But; just prior to takeoff; lebl tower again revised our departure to climb to 4000 ft MSL and track the lebl 247 degree radial. I; as captain and monitoring pilot; entered the lebl frequency and 247 degree radial to use as a backup to LNAV. The first officer; as the PF; incorrectly programmed the 240 degree radial in the FMS. Subsequently; after takeoff with LNAV captured; the first officer momentarily flew the FMS guidance (ie; the 240 degree radial) instead of the required 247 degree radial. Because I was talking to departure and monitoring the gear retraction; I didn't notice we were off course slightly to the south until about 2 NM out. When noticed; I used heading select and we quickly returned to the correct course. Lesson relearned: the monitoring pilot should always back up all FMS entries.

Title: B767-300 FLT CREW HAS A TRACK AND OR HDG DEV DEPARTING LEBL.

Narrative: DURING PREFLT; WE WERE CONFRONTED WITH SEVERAL ISSUES; FIRST OF WHICH WAS A HYD PUMP (ADP) THAT WAS INOP AND ON MEL. THIS RESTR OUR RWY ALLOWABLE TKOF WT AND SLOWED OUR GEAR RETRACTION TIME APPRECIABLY. IN ADDITION; FLT CTL SENT US 2 FLT PLAN UPDATES REVISING OUR BLOCK FUEL. SINCE WE WERE TOO HVY TO DEPART FROM THE USUAL RWY (25L); WE WERE TOLD WE WOULD USE RWY 25R AND A DIFFERENT DEP PROC. BUT; JUST PRIOR TO TKOF; LEBL TWR AGAIN REVISED OUR DEP TO CLB TO 4000 FT MSL AND TRACK THE LEBL 247 DEG RADIAL. I; AS CAPT AND MONITORING PLT; ENTERED THE LEBL FREQ AND 247 DEG RADIAL TO USE AS A BACKUP TO LNAV. THE FO; AS THE PF; INCORRECTLY PROGRAMMED THE 240 DEG RADIAL IN THE FMS. SUBSEQUENTLY; AFTER TKOF WITH LNAV CAPTURED; THE FO MOMENTARILY FLEW THE FMS GUIDANCE (IE; THE 240 DEG RADIAL) INSTEAD OF THE REQUIRED 247 DEG RADIAL. BECAUSE I WAS TALKING TO DEP AND MONITORING THE GEAR RETRACTION; I DIDN'T NOTICE WE WERE OFF COURSE SLIGHTLY TO THE S UNTIL ABOUT 2 NM OUT. WHEN NOTICED; I USED HDG SELECT AND WE QUICKLY RETURNED TO THE CORRECT COURSE. LESSON RELEARNED: THE MONITORING PLT SHOULD ALWAYS BACK UP ALL FMS ENTRIES.
