set pump to begin of delevery then set camshaft to tdc after removing injector pump then turn chank shaft with presure valve out and watch fuel come out of injector line while slowly pumping hand pump to maintain presure problem: the fuel stops at about 180 degrees and again at a little pased tdc please consider and help our car has been on the road for 3 days hoping for a speedy reply |

the engine timing should be 24 deg btdc when reinstalling the injection pump.the pump itself has marks on the spline that must lineup before you reinstall.

prob
the problem is i cant get it to 24 degrees because i use a protractor and its inaccurate i saw one of yellit's post's and if i read it correct is it possible to find the 24 degree mark with the drip methord what i need to find out is at what point does the cam have to be at and what point does the pump have to be at begin of delivery ? and another thing what is meant by cam lobes (borth cam lobes should be pointing up )and one last thing
is it possible that the crank shaft pulley is a protractor and has markings on it already becouse i saw this picture and thats sort of what it looked like so does this mean that i could get 24 degrees at crank shaft using the markings becouse i used super glue to glue a protractor on the camshaft nut (sort of stupid) my camshaft cover is removed so its easy to see tdc ps i dont have a drip tube can i use an injector line please post back as soon as you can as this is my last day to work on the car and i just found out i was suspended from school thanks |

you need 24 degrees btdc at the crankshaft pulley.could be difficult to see or non existent due to grease and dirt.using a protractor on the camshaft would work but keep in mind the actual reading would be different because the cam makes 2 revolutions i beleive for 1 revolution of the crank

You need to clean off and maybe take some sand paper to that balancer so you can see the numbers, 24 degrees should be visible then. You might consider listing your location as someone near by might pop over and give you a hand. If you didn't install your IP on the compression stroke (#1 cam lobes more or less up) you will be 180 out. I think I would pull the IP and make sure when you get the balancer cleaned up. My knowledge of the earlier 240Ds is really limited but I think what I told you does apply to your engine.

Speaking in general. On most engines you will most often find the timing marks on the Crankshaft Damper/Pulley. If not on the Crankshaft Damper/Pulley next common place is an opening to the rear of the Engine (often in the Bell Housing) where you can view timing marks stamped on the Fly Wheel (this is where they are on my Volvo).

This is a 2 part picture. The right side of the pic shows the numbers on my Mercedes Crankshaft Damper/Pulley. This will give you some idea where to look. If you need to do some cleaning down there to see the number be careful not to bend the pointer.

IMHO forget the drip tube for now not necessary to get the car running.you can fine tune later.with the basic adjustment 24 deg btdc and the injection pump set and properly installed you should be on your way

Like Michael said, if you installed the IP at the right place, it should start. Do you have the option of a "tow start"? She should go. Good luck

injector pump timing device
i sort of have a new problem i reset the camshaft and crankshaft timing now its accurate but then the fuel which has to stop at 24 degrees before tdc stops at 10 degrees does this mean that my injector pump timing device is off timing a little too advanced ? do i have to remove the vacume pump and jump a few links at the timing device or is it because i haven't set the ip corectly all i did was jump a couple of links off the camshaft

your best bet is to remove pump, not vacum pump. That gear should NOT be that easy to move on the chain. Your very close in your adjustment, only one tooth off actually I'll bet.
It's a tricky thing to learn especially when you need the car. Once you learn how to time them, it becomes second nature. It doesnt take much to bump or misalign the splines on the pump. Took me a few times my first time, and I was in a warm garage working on a car I didnt need. |
