I just purchased a 1980 240d 4sp and I have a couple of questions.
1) Immediately after start, oil pressure gage goes to upper peg and stays there until engine shut down, even at hot, low idle. Is this normal for this car? 2) The headliner is sagging. How does one remove it? 3) The left (driver's) rear C/V shaft is wasted. What is the easiest way to R&R it? Thanks in advance, Luchtaine ------------------ 1980 240d 4sp ASE Master Auto Technician ASE Advanced Engine Performance |

In my 240D oil pressure reads 2 at idle after engine has warmed up completely. Verify your idle speed. The 240D has a manual idle speed adjustment in the dashboard. It might be on(increasing idle speed)and giving you the increased oil pressure reading. The oil pressure gauge in my 240D goes to 3 right past idle speed.

from one ase master to another, I just replaced my LR axle shaft on my 1984 300DT.
Easy, drain rear axle, remove rear diff. cover, remove 'c' clip from axle shaft (in diff), raise up diff with a tree stand as high as it will go, remove bolt from other end of axle, 13mm head. punch the axle thru using a brass punch. when removing the axlewatch for the spacer shim against the diff side bearing. Assembly is the opposite of removal(always wanted to say that) ------------------ |

Thanks for the responses.
The headliner and C/V shaft are out. I checked the actual oil pressure against the gage in the car and it is indicating correctly. I am bothered by the design of the oil pressure indicator however. After running oil pressure readings, and further research into design operating oil pressures for this engine, it would seem that a gage calibrated from 0 - 7 or 8 bar would be much more usefull. Oh well, better that the needle stays on the upper peg instead of the bottom one! ------------------ 1980 240d 4sp ASE Master Auto Technician ASE Advanced Engine Performance |

I never thought about MB oil pressure gauges' calibration, until now, that is. All I can think of is perhaps that by dropping from 2 bar (at idle) to 0 would be a near-full-scale deflection of the needle, and be easier to spot than a drop of a quarter of the useful range of a 8 or 10 bar scale.
I know this is a stretch, and also wonder if my car has a low oil pressure idiot light, to back up the gauge. I know, MB would say it's redundant, etc., but I'd be quicker to spot a red light coming on rather than a drop in a gauge (especially at night). ------------------ Robert W.
