Who can check my timing and fuel pin Qs

[ARhine]

I am in a quite rural area of KS and need to know who I should try check the timing on my 93.



There is a local caseIH dealer, almost thought of aslking them since there is alot of case farm equipment with the 5. 9 cummins in it.



Lincoln NE and Salina, KS are about an equal 2 hour drive. Topeka is doable if anybody on here knows of good shops there.



Just have been doing lots of reading how the timing can really affect power. I also have the "wet dog" shutdown that I was reading about in some older discussions.



Maybe I am just reading to much :-laf



Also I think I have gotten the grasp on this fuel pin diaphram adjustment after reading up quite a while on it. one question yet is there a seal under the cap you remove with 4 screws that is going to need replaced? Also does this adjustment affect your overall power or just the rate at which you increase the fuel? In other words how much can I play with this stuff before the stock clutch and getrag don't like it anymore?



My pump already has no cover over the smoke screw, so I don't know what somebody might have been upto in the past.

The aneroid and pin effect the no/low boost fueling rate not the overall rate. In other words max power should be the same but it will make more power/smoke/egt's with lower boost. You can kill the getrag and stock clutch with no changes so a lot will depend on how you drive but you should not have problems. The full power screw is a totally different story.



Bumping the timing will help power, spool up, and the shake at shut down.



Any competent shop that works on the B series engine should be able to set the timing for you. To do it by specs you need a special tool to measure the fuel piston lift and set timing by the lift.



If you want to try it yourself you can use the eye ball method and rotate the top of the pump towards the engine. There will be timing marks on the pump and the pump support housing that will keep you in the ball park. Move the pump so the mark on the pump is about 1/8" above the mark on the housing and you should be in the ball park.

How do I know if I have gone to far on the timing? Are there any things to watch for.



I am gonna have to call a few places and see what they say.

I have read that the timing affects the shutdown, but not shure how? I mean the fuel has been cut to the engine, must just be the last injection causing it I guess.

If you go to far you will get what sounds like pinging on acceleration at low rpm's. Its a real metallic rattle and definitely different from the normal diesel rattle so its noticeable. When you ge tmuch past 15 degrees advance the VE pumped engines just make a lot of noise and not much more power. The rattle tends to go away with rpm's. Its should not hurt anything to run it that advanced but set it back ASAP so you don't run into head gasket problems.



When the shutoff solenoid close there is still 2 or 3 injection events worth of fuel in the pump. As the amount injected diminishes with the advanced timing it slows the engine rotation a bit more smoothly than it would if the injection event was closer to TDC. That my theory anyway.





Good luck and Happy Holidays.
