VolvoThe only risk here is getting injection mistimed, as all the engine timing happens on the front belt.If it does work, it will be real easy...and I''m about ready to grind a hole in the firewall getting the lock pin in n out I guarantee I can keep the lock pin more centered off the car than on. on the car you can't see the pin, and can hardly even feel it.I suppose the thing to do here is make the mark, install and time as normal....then see if my mark is aligned for future reference.you time audis and volvos from the front timing belt? how does that work? the fuel pump sitll has bolts and crap to adjust it.
VolvoI seem to remember having to hold the pump gear to keep it from springing back to get the pin in the hole. The 240s may have a bit more room than the 740s too. Never did a pump belt on a 740. If you get tired of trying You can ship me your engine if its a D24T. I'll get her timed plus boost my 245.The only risk here is getting injection mistimed, as all the engine timing happens on the front belt.If it does work, it will be real easy...and I''m about ready to grind a hole in the firewall getting the lock pin in n out I guarantee I can keep the lock pin more centered off the car than on. on the car you can't see the pin, and can hardly even feel it.I suppose the thing to do here is make the mark, install and time as normal....then see if my mark is aligned for future reference.
I'm saying the engine mechanical timing is on the front belt, so even if I borked the IP timing, there is no risk of bendies.Pump timing is the only thing on the rear belt, and is a moderate PITA, much the same as a 1.6 but more cramped.I was looking at the parts as i set up a test rig, and the thought of pretiming it crossed my mind...Good thing I tested it too, cause my new emergency stop lever seal pissed everywhere. go figure, it is the one feature on the pump my car is not supposed to have(was deleted in man trans cars)I think I have that fixed, and I need to bump the control pressure a hair, it seems to be at the very bottom of spec. Also I think my pressure gauge wants a restrictor, the needle was pretty bouncy
Is the rear cam sprocket keyed or can you spin it freely like on the Audi engines? On the 5 cylinder mTDI, when we were timing it in the van we found it easier to move the cam sprocket rather then trying to rotate the pump. If it's not keyed then I don't even think you would need to lock the pump.
