1984 300CD Sticking Throttle

I have a 1984 300cd and the gas pedal (accelerator) does not work any more. I thought that my car was sluggish because it needed a diesel purge (did that). Now the gas pedal does nothing. I tried to manually push the control linkage assembly and it seems to stick or get hung up. I think that I need a vacuum valve levers. Is there any thing else that would "loosen up" this problem? Thank you in advance for your help. Mathieu 1984 300cd turbo 314,000 miles

240D charging problem

My Battery drains occassionaly in my 81 240D. I had my alternator tested and it tested OK. The car runs fine otherwise. The only other thing I have noticed is that the Break Pad light and the break warning light comes on and stays on at low RPM. These lights go away when I increase the RPM. Could there be short in the break warning system or is it still the bad alternator and the regulator that is causing the the break light on the dashboard to come on?

Obscure parts needed: wagon rear side window trim clips

Have a 1981 300TD wagon in the body shop and have found most of the trim clips for the chrome trim on the rear side windows have rusted away. They are riveted in under the window rubber- need a complete set for both windows (not sure how many there are). Anybody have a parts wagon with good trim clips? Can email a photo of one for clarification... Thanks!

My '81 240D stalled, and now won't restart..

Okay..

I rolled my '81 240D off the ramps, after changing the rear
diff fluid (boy-- I bet THAT stuff was there since the Reagan
Administration!)..

It stalled when it came off the ramps, and refuses to restart..

IN THE LAST WEEK-- I replaced the passenger rear window (as some
vandal put a rock thru it!). Also last week, I changed the
transmission fluid (including draining the TC) and put up a new filter..

I also put up a new starter-- because the old one wasn't always
engaging.. (New one works fine, and I had it bench tested BEFORE I put it up)

Anyway--

The car has historically HAD a vac leak-- to shut it off, you turned
the key, and locked the driver's door, and it would stumble out.. The

Purpose of diesel hand primer pump?

On my '78 300cd there is a hand primer pump on the fuel line just upstream of the main fuel filter. Does this pump run continuously while the car is on to draw diesel from the tank? Or is it just there to act as an emergency hand pump if you run out of fuel? I am trying to determine the appropriate place to cut in my svo line.

Crank shaft pulleys fell off!

Mayday mayday!!!!!My crank shaft pulley sheared the bolts that held it (the pulley itself) to the crankshaft! There is a large bolt that appears to hold the flange that the balancer and pulley is fastened to. Is this correct? If so can I remove the large bolt to remove the flange to make the repair easier?

Better starter for 123 240D

Kent mentioned in one of his guides, that an old 240D engine that has trouble starting in the morning might benefit from being equipped with the turbodiesel starter. I have inquired with my repair shop and two parts suppliers, and they all maintain that the starter for a 240D and a 300 Turbodiesel are one and the same. Makes me wonder . . . has the aftermarket already upgraded to the "better" starter or downgraded to the "cheaper" one? Hence, I'd love to get some info, maybe a parts number for that one . . . Thanks, Bernard

Rear End Howl/Rear End Questions

I had an 83 300D Turbo which has a rear end howl issue. It has been that way ever since I got the car, which now has about 260000 miles on it, and I only hear the howl when I am applying throttle, when I let off the throttle it goes away. I am going to be replacing both rear axels in the near future since I am starting to hear some noise from the CV joints on 1 of the axels and figured since I am replacing 1 I might as well replace both. I have been told the whine is due do a worn pinon bearing in the rear end and that is putting excess strain on the gears in the rear end.

Center vents barely blowing

Can anyone PLEASE help me? I recently got the A/C working on my 1983 300D, but the air barely blows out of the two center vents. The air will blow strongly out of the far right and left side vents, but not the center ones. If anyone can provide me with possible reasons and/or solutions to this problem, I'd be GREATLY appreciative.

If you'd like to email me directly, my email address is maptgpkrp@msn.com

Thank you VERY MUCH!!
