M1097A2 injection timing

[Jan Micka]

Hi guys, does anyone of you have the specs for the injection timing? I just bought the tach n time meter and want to set the timing on my humvee. Seems to me the timing on my humvee is far advanced even though the marks are aligned. Or if someone has a manual how to do it I would greatly appreciate the help. Thank you very much

I am located in Europe and info is kinda hard to find. Thank you very much.

With NO history, what are the symptoms that makes one "feel" it not right or ?

Guessing here...so free advice.
Check the cold advance switch and solenoid circuit for proper operation? Injection pump internals components free and not gummed up?

Manual can be googled and reference here in section 4 D

Lots of other free info too

That's all you get for free, CAMO

Starting the engine in the morning the diesel rattle is to my belief way excesive, it almost hurt the ears especially parked in garage. When it warms up it is better but as I have already bought the tach n time, I just would like to know where I am at. Plus correct timing has an influence on consumption which a good excuse to check it anyway, 1 gallon of diesel is over dollars. Thank you very much for the manual.

Is this your first diesel?

Nope, third humvee plus 6,9 IDI diesel, this humvee is very noisy after start. So the timing should be 4 degrees at 1300rpm what I have read in the manual, of course engine at operating temp.

The Ford Navistar diesel 6,9 IDI is 8 degrees at 2000rpm which makes more sense to me as it is around rpm range the engine operates the most. I have an obsession with US cars, as I like to be different.

My "new" GEP turbo "rattles" considerably more than the old 6.2L
I would also be interested in how to confirm the IP timing

Especially in winter, my 6.5 TD rattles more than usual. Until about a mile down the road.
The cold advance seitch on RH rear block causes a timing change until warm. Doesnt it?

Action, the better part of the European world all drives, or has driven, Diesel something.

Jan!
Howdy to you from Germany!!

Hi, have a few friends in Gwrmany, all colecting wwII german warfare. I am in Prague. My only civil car is BMW diesel, still have to decide wether I want 1972 Gran Torino or Chevy Impala 66, and then I can die happy.

Other free guess... when checking / setting up TDC... Note clocking position of crank harmonic dampener to timing marks. Might have sheared the key and spun / slipped or??

It's a guess to consider if the TDC to timing marks flag is wack. Normally bent, twisted, etc.

I know...seen that on an alien space craft once, CAMO

Yes but the 6,2 has the same to my belief. The only thing that could be true my humvee is brand new, so the IP should perform perfect, all the others I have ever driven were higm miles. The design of the Rosamaster injection pump is rather simple and not very long lasting, they were considered wear item like the injectors.

It's suppose to for proper ACTION.

You knew that, CAMO

Ha! we don't have winter down here!

 

[papakb]

Not much winter down in Cams Mojaveland either! Just lot's of alien spacecraft to study. LOL! Sorry Cam, Hadda do it!! Kurt

WHAT ! Winters can be 15 degrees. Pipes freeze, Humv starts fine with the Camoteksystems controller. Runs for 3 minutes like it's going to throw a rod.
Where's my alien LASER gun for a show down, CAMO

Back at ya. POOF LOL

I am not too sure of that, I have two John Deere machines, a 350 dozer and a 310 loader backhoe, both are over 50 years old and I have owned them for over 30 years and both still have the same Roosamaster IPs I bought them with.
The 350 sat for 9 years in a pasture and I went out this week and tossed in a battery and she fired right up, now waiting her turn to get into the shop for a full fluid/filter change and possibly a re-core of the radiator.

Wait! John Deere is against self repair! You might void the warranty.

That is not the scary part, JD can permanently disable any of the newer tractors remotely by wireless connections through cell phone networks and satellite, their system is said to be full of faulty security measures, how long would it take for us all to starve if someone hacked the "system" and shut down every JD tractor in the world?

EDIT, fortunately nothing I own as far as farm equipment is new enough to worry about, I get a big kick thinking about the TV show Green Acres, the Fordson (re-labeled "Hoyt Clagwell" ) was only 30 years old when that show was taped and I work 50-60+ year old tractors daily, the 1900 Oliver (453 Detroit) I use regularly is 62 years old, weighs about 16,000 lbs and has armstrong steering, simple as can be, why it still runs like new.
