    Hi

    You may have seen from my other thread that we have has some problems with our Peugeot. The AA man has been out and thinks it may be the timing belt that has slipped and thrown the injector pump out of timing.

    Does anyone know how to set this up after the timing belt has been replaced?

    Thanks in advance :thumb:

    How old is the vehicle? Do you know if it's a common rail diesel?

    If so then no pump timing from belt and if not then basic timing is done with locking pin on pulley and refined with dial gauge.

    Thanks for the reply.

    No it's not CRD. It is a 1994 L plate. Rich says he hasn't seen a gauge do you know where it is? Do you know where the adjustment on the injector pump is - would you be able to help with that?

    you generally need three locking pins...

    one for the crankshaft, normally on the flywheel.

    one for the cam shaft, normally on the cam pulley

    one for the pump, normally on the pulley.

    personally i use allen keys of the correct diameter.

    once you find TDC on #1 cylinder the pins SHOULD push into place and lock everything up.

    if the pump timing is out you MUST insert the crank and cam locking pins first then remove the belt and turn the pump pulley slowly by hand, one way or the other, until the pin drops into its hole.
    it will only be a few degrees turn on the pump pulley to realign it.

    obviously you will fit a new belt, idler and tensioner before putting it back together.:Doh:
    you will also need a large torque wrench to retighten the crank nut...i think its around 240lbf...beyond most diy wrenchs.

    First thing would be to determine if indeed the timing belt has jumped teeth, which is VERY rare without breaking totally. If so, then as PJ suggested, new timing belt, tensioner, idlers and probably waterpump would be needed.

    Anyone capable of 'properly' replacing the timing belt should be in a position to determine pump timing situation.

    Further engine damage is possible if valve timing is also an issue as the same belt keeps pistons and valves in sync as well as pump timing.

    on an old vw lt38 i used to own the auxiliary belt broke and somehow got in to the timing belt casing and caused the timing belt to jump about 3 teeth.
    so if you are replacing the main timing belt make sure all idler pulleys and anything the timing belt goes round are replaced and as a precaution replace the aux belt/s also.:thumb:
