IP 180deg off, is this possible?
HI Guys,
I purchased this 220D from a fellow who told me that car just stopped running??? I think I have found the problem. I have good fuel, glow and battery but I think the fuel/injection pump is off 180 deg, is this possible? I turned the crank 24deg BTDC and did the drip test and she flows like a river. I turned the crank another 360 deg, again to 24deg BTDC on the next rotation (not for #1 cylinder) and the drip test can be set. With the limited knowledge that I have I can only assume that the pump is 180 deg off. How do I change this? I have no idea what all has been done to the car but it looks as if it has had a good amount of attention recently. New starter, battery, hoses and such. I think all it needs is to have the timing corrected. Andrew |
If it was 180 degrees off, it wouldn't be injecting on the compression stroke, right? So figure out if #1 is injecting when the #1 cylinder is at the top of its compression stroke.

Andrew, there use to be a lot of Guru's on this forum that could answer your question. I would say that if you spent just a little time doing some really basic search on the "Diesel" part of the forum, you would get more info then you could read in an evening. I don't have an answer except to say that at 79 years of age I would be scared to death of messing with the IP. It is very critical, but we have guys that can do it. Just go to search and find them!

Here I come up with 8 pages of Forum talk on "Setting injection pump" You should get them all by clicking on this. That is a lot to read, but I bet the answer is in there.

To answer your question; with out someone pulling the Fuel Injection Pump off of the Engine and re-installing it wrong it cannot be 180 Degrees off.
For what ever thier reasons previous owners do not always say the truth. I would suggest checking the Camshaft Timing First to see if that is correct since the Timing Chain turns the Fuel Injection Pump. Not hard to do. Line the Timing Mark on the Camshaft Gear up with the one on the Camshaft Bearing Tower and look down at the degree marks on the Crankshaft Damper. Another issue is that the Degree Pointer sometimes bent or otherwise moved around.

I followed the DoItYourSelf article for timing the IP and all I get is a steady stream from the drip tube even when I push the IP as near to the engine as possible. I will try again in the morning. The car has sat here for over 8 months now and I might as well try and get her going. Its a nice car and it would be great to get it on the road. I will part it out this winter if I fail to get her going. Thank you for your comments and links. Andrew |

To determine the actual start of delivery, rotate the crankshaft, not the IP. |

Hi Tangofox, Is there a DIY article or any information on re-indexing an IP? Regards, Andrew |

Set the crankshaft at desired start-of-delivery position, remove IP, align IP index marks, reinstall IP in center of adjustment range. Then adjust SOD. You could probably get away with just pulling the IP out, rotating it (the entire pump, not the shaft only) in the retard direction, then reinstalling it. That will give you the needed range of movement in the "advance" direction. |
