Hi I'm sorry if I've repeated a common asked question, but why does the camshaft pulley have to be removed when changing the cam belt? I have a 9 year old Transit connect with 68k on the clock. My son recently changed the cam belt on my wife's Peugeot 1.5D and he said he would do my connect. On reading the Haynes manual it said to remove the cam pulley. His normal method is to lock the crankshaft and cam shaft pulley, remove the tensioner remove the old belt, replace with the new belt, put on the new tensioner tighten up,but the Haynes manual says to remove the camshaft pulley. Have we missed something? I appreciate any answers and may decide to ask a garage to do it if necessary.

Theres the proper way to do it with crank locking pin, cam alignment plate etc, thats quite involved and fair bit to remove to access the crank locking pin location.

Or the easy way, remove cover , mark postions of pulleys against backplate with dab of paint, remove belt and fit new.
