Re: [MBZ] adjusting valves
I used a drawing. I also used 2 sets of feeler gauges and just adjusted whatever one was next up when I turned the cam. I discovered 2 things that I hope to remember for next time. The 2nd from the last valve - (exhaust on #5 I think) required that I use a different wrench. I have the special bent wrenches and they worked fine everywhere else but that one is too close to the cam support tower and the firewall so I used the bent wrench on the bottom nut and a normal wrench on the upper one but had to mess about to find a wrench that was the right length. The other thing is that I want to find a different wrench to turn the power steering pump. I think, maybe a ratcheting boxend with a modified handle so it sticks up a bit higher. I still have bruises on both arms from my efforts to turn the cam. Randy On 22/07/2014 9:57 AM, LarryT via Mercedes wrote: I put a dab of White-out on the valve stems as I adjust them.

Yes, that was why it caught my attention.

Re: [MBZ] adjusting valves
Rick, thanks, that's the video I was thinking of. I had the author wrong, and down in the comments is one from the author about turning the valve spring retainer to adjust the valve clearance at the TIGHTEST (?) point. That didn't make sense to me, I would imagine that the retainer would trend to find the most loose point and settle there.

Re: [MBZ] adjusting valves
I have no real fear of doing it. It is a bit of a dirty job but I have become a nitrile glove believer so I should avoid getting black fingers if I am careful. I have done valve adjustments on many vehicles over the years but never on the diesel. It no doubt has needed it for a long while and I hope to notice a difference. One of the issues is hard starting once it starts to cool off in the fall and I believe that is an indication that the valves are likely too tight.

Re: [MBZ] adjusting valves
I don't recall if it's been mentioned but (1) always turn the crank shaft in the direction of normal rotation and (2) it's easiest to turn the crank shaft by turning the power steering pump nut (vs the actual crank shaft nut). This should work if the belt tension is correct. While you are there, check chain stretch by aligning the marks on the cam tower and sprocket and reading the number on the timing pulley in the crankshaft. Do it several times to get a reliable number.

[MBZ] adjusting valves
I have been more than a bit negligent in terms of keeping the valves set on my old 300D. I bought the tools and the new gasket but have yet to do it. I was thinking about it this past weekend and did a bit of searching online. The advice offered was pretty loose. My past experience with gas engines required one to turn to the specific timing marks etc. The advice offered on the diesels seemed to be just to turn the cam so that the point sticks up. Is that considered close enough? I have never disconnected the throttle linkage? I seem to recall someone suggested one just pops them apart by prying with a screwdriver? Is that correct? I really don't want to damage anything by my own lack of knowledge on how to do it.

Re: [MBZ] adjusting valves
If you're setting valves on a diesel, you want the cam lobe to be 180 degrees (opposite) the flat spot on the follower. That's not necessarily straight up. I eyeballed it for years and never had a problem. Straight up is not usually 180 degrees out.

Re: [MBZ] adjusting valves
I would add that the gap will change as you tighten the jam nut. So measure the gap before you loosen it. Guess at the required adjustment and do it then retighten and measure. After a few valves you'll get good at guessing and dial each one in with only one or two attempts. Also, I make a picture of the valves and write down the before and after gaps for each valve. That way I don't miss any or double adjust any. It's also interesting to see how much adjustment was needed. Also, wear plastic (like nitrile) gloves; Diesel oil stains.

Re: [MBZ] Adjusting valves - was: 240D success!
Curt wrote: Today I tried adjusting the valves, I'll not try that again until I get a proper set of wrenches... I use normal flat wrenches - except I have one ground thinner. I found the intakes all slightly loose (0.13mm) except for one that was perfect. Loose is good! Too loose and it effects power, but too tight and the engine will leak compression which has a bad effect on cold starting. The exhausts were all slightly tight (0.25-0.28mm). That's what normally happens. Considering the rough adjustment I was capable of I decided I'd loosen the tight exhaust valves and leave the loose intakes where they were, even then the adjustment took me right on 2 hours, most of that was farting around not knowing what I was doing. Just for the valves? Or including messing with the fuel feed linkage? The offset wrenches might help some, but it's still a fiddly process as tightening the nuts _will_ change the size of the gap. Practice will help. *smiles* -- Philip ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Why not simply run the engine, long enough for it to reach some uniform temperature, shut it down, and just as it cools enough to work on it safely, do the adjustment? That should allow doing it above the freezing temperatures of the day, and also have some mercy on the fingers. Of course, you would want to warm the tools beforehand, also!

I have not done the valves in 2 yrs and I don't have a heated garage. Absolutely ok. The colder it is when you adjust them, the less likely it is that they will be held open during a colder day. The clearances when normalized will be slightly looser but that improves low end torque, with only slightly noisier valve clatter.

Insulated coveralls help a bit, but I am still suffering from my jaunt on the ground yesterday; Hans had an 8mm coolant line pop out of a clip and rub itself to death on the intercooler... To get at the line entailed removing the bumper (4 bolts, thankfully!).. I just used a 5/16 compression union on it, seems to be holding fine.. BTW i found out that I have weeping from between the nuts and the pipe on my oil cooler lines, Thankfully the OM606 has 4 lines; two hoses from the engine to the body hard lines, then the two body hard lines down to the aluminium radiator. Unfortunately it is the body hard lines that have the weep, so it looks like headlight removal time and probably dremel time (split the nuts and they will hopefully unscrew... but they might not be siezed either. It will be decidely easier to get at the cooler with the bumper off. I'm hoping that the radiator is not leaking as well. Does anyone know how much oil the lines and radiator hold? (210.025/OM606.96x) I'm guessing about 2 qt. I also found that the bolts securing the sway bar to the chassis tend to round off (#[EMAIL PROTECTED] E-10 heads) and were up-reved to Hex heads. I'm hoping that Craftsman external ez-out sockets will get a good bite on the now round heads and spin them right out. Additionally, on the stuck lug nut, I found that my locak dealership has a guy who is good enough with a plasma cutter to just blow the bolt out of the hole (!).

It did cross my mind to leave the block heater plugged in all night and while I was working on it. I thought by then the engine temp should even out. As far as the cold temp as long as I get out of the wind it's really not that bad, and after the fingers get that fat numb feeling. Right Lt. Don.

That should allow doing it above the freezing temperatures of the day, and also have some mercy on the fingers. Of course, you would want to warm the tools beforehand, also! For the engine to be at a uniform temperature throughout, the engine must not have been run for 6-8 hours (not even for a minute or two). Unless the engine temperature is uniform, valve adjustment will be uneven. Once shut down, the front, center and back of the engine cool at different rates. Using the block heater would not be particularly desirable either but not as bad as running the engine. What is required for reliable cold starting is that there be SOME valve clearance at the coldest temperatures expected (clearance decreases as the temperature drops because the valves and the head have different temperature coefficients). The precise clearance is not nearly as critical as sufficient clearance for reliable cold starting. Uniform and correct clearances are required for the engine to run most smoothly.

Werner Wouldn't that be to wait for operating temperature? If its somewhere inbetween different things could still be at different temperatures (heck, thats prolly true even at operating temp). The plate on my car says if above a certain temp use xx values or if its below that temp use... etc. (I don't remember the values or temp, but know that I've always needed the 'cold' ones). IMO, its been two years since the valve adjustment was done the little itty bitty differences in tolerance from the super cold temperatures are most likely insignificant compared to how out of clearance they are now. Besides, its not like they'll never be out of adjustment again ;) Warming tools... I'm going to have to try that one! :) Any spiffy warming method or do you just keep them inside? John '79 300SD

Re: [MBZ] Adjusting valves in cold weather
Thanks. I noticed a decided difference in engine running between stone cold (overnight sit) versus warm adjustments. I always wondered why, or if it was something that I was doing wrong. I've gotten to where I can adjust them on the street in 30 mins (It has gotten a question or three from the neighbors, but they have grown to accept it.) -j. -- John Reames 1985 300d (223K Gerta) 1991 Cherokee (149K the fishbowl) 1999 E300Dt (140K Hans) (the leaky one) 1999 E300Dt (106K Frantz) (the squeaky one) -- Original message -- From: Marshall Booth [EMAIL PROTECTED] Unless you are much faster at adjusting valve than I am, the warm values ALWAYS result in unreliable valve adjustment since the engine is cooling while you are adjusting the valves.

As I understand it compensation for volumetric efficiency vs rpm needs to be taken account so that at low speed and at hig speed the maximum injection charge is lower than at mid range rpm due to rereduced volumetric efficeincy. Let me make sure I understand what you're asking real quick. :) On the volumetric efficiency vs RPM are you talking about the amount of available air for combustion inside the cylinder based on RPM (things like boost and/or losses changing that over the RPM band)? If thats the case, then the amount of injected fuel (injection charge?) does have different limits across the RPM range. The reason for it is that if you start injecting too much fuel you will start generating clouds of black smoke (partially burned fuel). I have a graph in a Bosch tech book that shows the max injected volume vs RPM and it does do what you describe. I can post that if you would like that extra verification :) As to HOW thats done that is where the complicated part (IMO) of our governors come into play. In the governor used on the MW pumps I believe it is called torque control. There are very few people who truly understand exactly how it works (and how to change it), and I am certainly NOT one of them. If you are interested in learning more about how IPs work I'd highly suggest this book It talks about all kinds of IPs and how the governors work, etc. As well as a fairly detailed overview of diesel combustion, etc. I sure enjoyed reading it and learned a lot :) http://www.boschtechinfo.com/index.cfm?event=product.searchkeyword=1%20987%20723%20602 John '79 300SD
[MBZ] Adjusting valves in cold weather
Would it be OK to adjust the valves on a 85 300D in cold weather, say 20 degrees F, or would it be a no,no? I have not done the valves in 2 yrs and I don't have a heated garage. _ Valentines Day -- Shop for gifts that spell L-O-V-E at MSN Shopping http://shopping.msn.com/content/shp/?ctId=8323,ptnrid=37,ptnrdata=24095tcode=wlmtagline
