adjusting valves

[FreightTrain]

how often does the 465 require valve adjustments and is there a Civilian way to do it?

Does it sound like a Smith Corona typerwriter? When the valve clearence is correct, it will sound smooth and will run better. Mine had .050 + clearence on the exhaust, and was getting real bad mileage..about 4-5 mpg. Did a tune up, mileage went from 5 to 8, revved better and the smoke toned down. It's pretty easy, took about an hour to do it, including pulling out the tools. Yes you can do it with 1 person. I just used a wrench on the back side of the compressor pulley and pushed down on the compressor belt to tension it enough to turn the engine.

How often? Once in 30 years would be more often than they have had it... would be a good exercise for you as it is all at the top of the engine and it does not have to be running...do not know what "Civilian way" means...if you mean quick and easy, it is already that way...Military way would be to replace engine complete while they are teaching the Ord Mechs how to read the crummy manuals...and fighting over who Soldier 1 is going to be today.

Which manual has the valve lash adjustment specs?

 

[clinto]

Pretty sure it's .010 on the intake and .025 on the exhaust...........specs are on the engine tag on the pass. side on the front side of the engine.

I turned the engine over using a prybar on the jackshaft between the tranny and transfer case....but it goes without saying that making sure the engine stop cable is fully pulled out is a good precaution

Can't remember which manual it is........"organizational maintence for LD/LDT 465 series" or something like that

Here is something.

As always, Bjorn had it right. I would have said .025 on both sides and been wrong. Gotta remember to read the TMs BEFORE I post to get the numbers.... DO read the TM's before you try this at home, they tell you how to adjust all 12 valves with only 1 (manual) crank of the engine, better to get it right the first time. I need to check my valve adjustment, except I sold my spare set of valve cover gaskets to Bjorn after his 2x cross country road trip with the cranetruck.....
