Engine/Transmission (1998.5 - 2002) First 24V Adjustment Complete

where did you buy the "Cummins top-end tune-up tool kit. " that might be something I would like to purchase.

I bought it at Cummins store in Glen-Burnie, MD. I did a search but couldn't find it. I'll look at the kit tomorrow to see if it has stock or part # on it. I saw barring tool by itself selling for $40 and that's less than I paid for the whole tool kit.

if you can find that part number that would be great. thanks

No single Part # Listed

I dug out the parts kit, but here is no part # listed for the set. Cover says: Cummins Performance Tools. All tools (swivel head 3/8" ratchet, long ext , two combination wrenches, feeler guage, seven sockets, 3/8" to 1/2" socket adapter, stubby flathead screw driver, oil filter wrench and barring tool) all have KD, USA and a part #. The part # for the barring tool is KD3824.



I checked Cummins web site and could find link to their specialty tools, but no luck. You may want to contact Cummins and see if they can look it up.



Take care, Wiredawg

Got some injectors coming, if they ever get here, seems it'd be a lot easier to adjust the valves while the old ones are out and I wouldn't have to fight compression to turn the engine. There's about 85k on my truck and one sounds a little noisy unless I'm confusing that with the sound of the mighty diesel.

I wouldn't have to fight compression to turn the engine.

The barring tool makes turning the engine over a snap.

I just read the service manual for the 24 valve diesel engine valve timming. It calls for 0. 006 in min. to 0. 015 in max for the intake .

0. 015 in min to. 030 in max. for the exhaust.

Then it go on to say if the valves are with in these specifications no ajustment necessary. also states no affect on performance, emissions, fuel economy or level of engine noise.

I adjusted my valves today, actually. 165K on mileage. couple intakes were couple thousand loose. Several exhaust were several thousand loose.

The trick to removing the valve cover is to remove all but the rear bolt from the cover hole. If you slide the rear of the valve cover towards the left side of the engine, and the front of the valve cover towards the right side of the engine you can remove the cover pretty easily. Yeh, you have to wiggle it about some for the bolt to clear the #6 rockers, but that is how I do it.

I set intake at 0. 10; exhaust at 0. 20. Idle is smoother. Lower rpms are snappier. Engine generally seems to have more power and run smoother.

Now, I cannot help but think this might help the fifth gear loose nut problem. If the theory about engine vibration at low rpm is the true cause of the loosening fifth gear nut, then anything to make the engine run smoother should have some beneficial effect on not loosening the nut.

Removing the turbo silencer ring (an easy 2 min job) is another thing that smoothes out the engine at low rpm. My engine quit the black smoke excerise at low rpm when I fed fuel to the engine and I seem to have more power
