Nope. All you can do there is either put in a new one or get an
old version that you can stretch the spring on.

From what I see the 603 one has the non removable end so I am not sure you can
get the spring out?

Manfred,
Are you suggesting that the changes in your engine operation are due to your
stretching the relief valve spring?
And Curley - have you tinkered with the same spring on the OM603 engines and
seen a difference in performance or operation?

My 300TD is still doing a nice smooth idle and does seem to have more power and
oddly enough the engine is quieter both at idle and going down the road. I have
the impression that it accelerates as well now as it did before I put in the
lower ratio differential from the 84 TD. After I had put the differential in I
noticed a definite slower acceleration that is now gone. The mileage on the
first tank, and I always fill till I see the actual liquid fuel at the top of
the fill pipe, with the 5% correction for the difference in the gear ratios has
gone up to 26.2 from 24.6. That was mostly a trip down to Orlando including a
lot of stop and go both on the way down (441) and in town there as well as
using the AC all the way back. I expect that it may go up a bit with my normal
driving around the G'ville area.

Did the spring stretch on the 300D pressure valve. The spring is definitely
the original based on a visual inspection, and was barely 2 cm long. I
stretched it to 27 mm and installed it. A definite difference in idle
smoothness - he engine doesn’t sway nearly as much as it had previously, so
this is good.
Might just do the steering stabilizer on the 350SDL in the driveway, since it
won’t take but a couple of minutes. I’m thinking I’ll save the SL500 for
tomorrow. Gotta pace myself….
