The Citroen BX Diesel (XUD engine) is even easier. Turn the engine to the 
timing position and put 1 M8 bolt through a hole in the camshaft sprocket 
(it screws into the cylinder head) and 2 through holes in the injection 
pump sprocket (they screw into the block IIRC). Put a timing pin (an 
Allen key will do) into the hole behind the starter motor so that it 
slips into the hole in the flywheel. Remove the belt, fit a new one, 
remove the pin and bolts, turn the engine 2 full turns by hand, then 
check you can fit the bolts and pin back again. If so, it's correctly timed.
