keithjh Posted August 17, 2015 Share Posted August 17, 2015 Hi All, Have just changed the timing belt on the 200tdi (disco engine) in the 90, lined up using timing pin when removing old belt new belt installed (Dayco belt & new belt tensioner). Turned engine 2 revolutions as per book, woodruff key on crank looks to be about 1/2 a tooth off the timing mark clockwise. Pump timing mark is spot on, thoughts please before I go any further.

miketomcat Posted August 17, 2015 Share Posted August 17, 2015 Sounds like you need to loosen the bolts on the injection pump with the timing pin in line up the crank and cam pulleys then tighten the pump bolts. Turn over twice and check it should be right after that, if not remove the belt and start again from scratch. Mike Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 17, 2015 Share Posted August 17, 2015 Set the crank and the cam on their respective timing marks and adjust the pump sprocket. Bear in mind that the sprocket retaining bolts must not be at one end or the other in their slots. Les Quote Link to comment Share on other sites More sharing options...
defender dinky Posted August 18, 2015 Share Posted August 18, 2015 do you need to lock the flywheel to do timing, dd Quote Link to comment Share on other sites More sharing options...
miketomcat Posted August 18, 2015 Share Posted August 18, 2015 You can but as long as the keyway is at the top you should be fine I don't bother. Mike Quote Link to comment Share on other sites More sharing options...
keithjh Posted August 18, 2015 Author Share Posted August 18, 2015 All sorted, had totally forgotten about slackening the sprocket retaining bolts. Regards Keith Quote Link to comment Share on other sites More sharing options...
