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.

Hi
The Rover 2000 had two pins bolted to the engine.
One pin held the flywheel while the other held the cam
shaft. But then it was a chain and required a lot
of disassembly to replace the chain.
The main purpose was to hold things while one removed
the cam shaft to install adjuster shims for the valve
clearance. To make things a little more tricky, the
same bolts that held the cam shaft bearings were also
the head bolts :(
