Yes
YesWas there a gasket between inj pump and timing case?
Try and find the instructions for the 300 belt mods, as Iirc there was some things you had to do when fitting the inj pump.Thinking out loud so bear with me.
Crank gear can't be in the wrong place and cam gear can't be wrong. That leaves the injection pump which has a gasket (although I can't see that makes a difference) and also has the pump rear support bracket. So I can't really see how that would be wrong.
Could the actual timing case play a roll in all this somewhere, it's a 2nd hand one from Turners, could it be out of whack somewhere?
Could be the inj pump or the timing chest that is not square, ie something stopping either one seating correctly.Using my Heath Robinson straight edge the cam gear and crank gear are good.
Using it across the cam gear and injection pump gear it suggests the outer edge (nearest the outer edge of the casing) of the pump gear is further back. There is a 1.6mm gap between the gear and straight edge, measured with feeler gauges.
Would that suggest a warped timing case?
I'm going to remove the injection pump gear and pump and reseat them tomorrow and see if I can see anything a miss. Quite what could be wrong I don't know.Could be the inj pump or the timing chest that is not square, ie something stopping either one seating correctly.
Remember cam and crank are square as they are in the block, inj pump and tensioner rely on the timing chest.
Straight edge across front face of timing chest and measure from straight edge to the face of the gears?I'm going to remove the injection pump gear and pump and reseat them tomorrow and see if I can see anything a miss. Quite what could be wrong I don't know.
Have a watch of this, quite interesting.
