Help!!!!!!!!!

cummins_785 · 01-28-2007, 09:50 AM

Ok took my pump off to do some work to it, got it back put it back on, killed the KDP and now i cant get it to start. The one thing that i can think of is that when i took the pump off i did not have the motor complelty on TDC, and when the pump was off they adjusted the timing. So i need help on what i can do to fix it, i am not sure if that is the problem or not but i do need some advise, Thanks.

When you remove the P pump it is absolutely critical that the crankshaft be aligned to TDC, and that the pump itself is then lined and locked by its internal locking pin, before you remove the nut that holds the pump drive gear.

I am a bit confused about someone adjusting the timing with the pump off, as that would tell me that a qualified pump shop has gone into the pump and moved the lead timing. The only user set timing is done with the pump installed on the engine and properly indexed.

If someone adjusted the engine timing with the pump off, you are screwed, and now need to return all the timing and cam gear drive train to the proper index markers.

The best way to do that is to pull the front timing cover and align all the timing marks, then index the pump and align that drive gear to the reference mark for zero there. Then, and only then, will you be ready to actually time the pump.

If you do not have a repair manual that can walk you through the indexing of all the gears in the front of the engine, pick up a Haynes Manual #30041 and follow the instructions to the letter. You may also find that the pump's indexing pin is stuck and will not lock the pump. If so, you will need to work that nylon pin loose by using penetrating oil, and then get it so it can be lined to the internal pump shaft and pushed in and locked before you do anything else. Do not get any dirt or dirty oil in the open fuel lines, the injection lines, or the delivery valve towers on the injection pump itself.

Sometimes the indexing pin on the injection pump will break, but it is still possible to find TDC manually by measuring lift height of the pump's #1 piston. That takes a special wrench, a dial indicator, and lots of patience.
