Application Specification
Generator/water pump drive belt Burroughs method: new belt 556 to 578 N. Run for one minute, allow belt
(normally aspirated engines) to cool and reset to the in-service setting. If in-service tension falls below
356 N, reset at 511 N to 534 N.
Clavis method: new belt 174 to 180 Hz. Run for one minute, allow belt to
cool and reset to the in-service setting. If the in-service tension falls below
140 Hz, reset at 167 to 173 Hz. (Measuring point: mid-way between
crankshaft and generator pulleys).

Generator/water pump drive belt Burroughs method: new belt 560 to 600 N. Run for one minute, allow belt to
(supercharged engine) cool and reset to the in-service setting. If in-service tension falls below
335 N, reset at 405 N to 445 N.
Clavis method: new belt 180 to 186 Hz. Run for one minute, allow belt to
cool and reset to the in-service setting. If the in-service tension falls below
131 Hz, reset at 155 to 161 Hz. (Measuring point: mid-way between
crankshaft and generator pulleys).

Generator drive belt (V12) Burroughs method: new belt 775 N. If in-service tension falls below 230 N,
reset at 400 N.
Clavis method: new belt 182 to 188 Hz. If the in-service tension falls below
119 Hz, reset at 137 to 143 Hz. (Measuring point: mid-way between
generator pulleys).
