    Angry TDC cambelt change 1.8 diesel escort

    Hi, I am in a bit of a quandry, My cambelt snapped whilst starting my van on my drive, it just fired and then snap!, my injector pump belt is intact, I've got the lot stripped out on my 96 (N reg) 1.8, 55 diesel van, inner wing off, alternator off, all covers etc etc, got the full belt kit and tensioners, but, I cannot for the life of me find this crankshaft locking off pinhole on cylinder block!, think I will have to use a mirror to look above alternator bracket, is it removed with alun key? it does not say with diagrams and instuctions that came with belt kit from Ford! If I cannot do it this way, is there another way of locking off the crank, assuming all other markings are lined up correctly? whilst on the diagrams, in said instructions, I have on plate at back of camshaft sprocket a silver mark at 12 o'clock position and a silver mark on sprocket, do these have to be lined up? on my injector pump sprocket casing, again, a silver mark at 12 'o clock and one on sprocket, do they line up as well? I ask this because in the instuctions mentioned above it says to lock off cam sprocket with tool (6mm drillbit) when I do this the only hole it will lock to puts the mark on cam sprocket at the 4 o'clock position? On fuel pump sprocket there is a tiny dot like drill hole on a cog tooth (bit like a timing mark) when this is aligned at 12 o'clock, that silver mark is at 4, o'clock! My thoughts were that if I line up both sets of silver paint marks and can lock of crankshaft then it is at TDC but as explained above this doesn't tie in with my markings and explanations etc ( the ford instructions are dated 2000!) Please please someone explain before I top meself!!!!

    The Crankshaft locking hole is above the alternator, You have to remove a plug first. The camshaft locking hole is inbetween 2 of the 4 bolts and lines up with the engine locking hole at approx 9 o'clock.
    The slot in the Injection pump sprocket should be at 12 - 1 O'clock to put the locking pin in.

    Don't forget to slacken the bolts on the cam and pump before tensioning new belt. Always use a pulley holding tool - never tighten or loosen against timing pins or the belt.

    make sure engine turns over easily by hand before trying to start it.

    Question TDC cambelt change 1.8 diesel escort

    Many thanks Mr Danno, I have actually located the plugged hole in crankcase, and the holes in cam and pump sprocket\block, but what is confusing me is the existing silver paint marks on sprockets and casing, are they what someone else has used or are they normal, if so what relevence (if any) are they to the TDC, as when these marks are lined up the cam and pump sprockets cannot be locked because the locking holes are miles out? It looks like the common sense and obvious way is to line these up together! Hope you understand my apprehension, if the belts are put on wrong its a ton more work to strip all out and start again!

    Well, Chances are that someone has put these 'painted' on timing marks and changed belts when the engine was not at TDC. If it was me I'd go with using the locking pins and dis-regard these painted marks.
