shizzl Posted December 6, 2012 Share Posted December 6, 2012 we chucked a rebuilt 5l-e hilux motor into the work truck today,it got a new cambelt aswell.. it fires up mint but is knocking,almost bottom end type noise.. could it be possible that the timing is out? do you these pumps always time to tdc when the mark is on the timing mark? ie: if the belt is off and someone decides to turn the d-pump round one turn before the belt is on, will this put the timing out? (the pulley marker is meeting the front cover marker but pulley has been turned)... i havent had much to do with diesels so not sure how these pumps and timing work... does one full turn of the pump pulley do 1 squirt to all 4 injectors?

shizzl Posted December 6, 2012 Author Share Posted December 6, 2012 so the timing will be out? how do you find the tdc at pot one on the pump? Quote Link to comment Share on other sites More sharing options...
smokin'joe Posted December 6, 2012 Share Posted December 6, 2012 so the timing will be out? how do you find the tdc at pot one on the pump? there are timing marks for all 3 elements. crank pulley, camshaft pulley and injector pump pulley. should be an embossed triangle on the backing plate that lines up with the notch on the pulley at about 10 o'clock.1 tooth out on injector will make it gutless 1 tooth out at the crank and it will sound like bigends or mains have spun Quote Link to comment Share on other sites More sharing options...
shizzl Posted December 7, 2012 Author Share Posted December 7, 2012 got to work this morning feeling rather deflated and pissed off.. took the cambelt cover off to have a gander... fucking belt had jumped 2 teeth on the crank pulley!!! changed it back, spun it over a fair bit, all good. put it back together and shes running mint as....but fuck its gutless, useless non turbo diesel toyotas.... cheers for your help guys... this was my first ever full 4cyl rebuild, thats gone further than a head gasket on a pushrod hemi... stoked Quote Link to comment Share on other sites More sharing options...
Grotty Posted December 7, 2012 Share Posted December 7, 2012 Have you dialed in the pump timing aswell? Quote Link to comment Share on other sites More sharing options...
My name is Russell Posted December 7, 2012 Share Posted December 7, 2012 1st time i did a diesel didn't time up the pump and not allot happened. Another diesel had crank 180 out which resulted in 0 compression And have done belts on current diesel several times now tracing leaks So messy to work on! No help sorry but good luck.
