Diesel RVs: Re: [diesel_mercedes] Re: Gas pedal Linkage

Let me rephrase that I lubed all the connections I could see from the engine bay. I wonder if I have to go from underneath? perhaps there some connections maybe that I have to lube from underneath the car perhaps?

Considering the problem didn't exist until after it sat for 6+ months it leads me to believe that the bushing is okay and maybe there's a location that I've not lubed?

So I lubed all the balls. But the problem persists. I believe it might be the it may be the bushing in the firewall. How do I access it from the inside of the car I can not even get my fingers up where it travels through the firewall. Is this something I accessed from underneath the car?

Even after lubricating all the connections the pedal feel is linear only halfway through its travel and I really have to squash down hard that second-half where it only moves a fraction farther. I'm guessing it has to be the Busching but I'm not sure how to get to it.

Thanks for your help,

There isn't a cable , it's all thin steel rods with ball joint ends , they need periodic lubrication , moreso if you live where they use salt on the roads or it rains a lot .

Ma 'Benz says to use ATF , I use Aerosol Chain Lube , it comes with a nifty red plastic snorkel making it easier to squirt into the ball joints as you're operating the throttle with your other hand .

On the firewall is a plastic bushing thing that must not have *any* play , it is made to rotate but as it ages it often lifts up a bit when the throttle is depressed , this means you need another one , new or good used , I've seen them made from chunks of scrap plastic and so on , IMO the correct part works best because it's designed to pivot and allow the engine's normal movement .

There's always plenty of new new ones on junked Mercedes .

Get all the rod balls well lubed up before touching , repairing or adjusting anything else .

Be aware that if you attempt to ajust the rods , you'll prolly screw up the tranny shfting badly as it's all connected to - gether .

> I have a 75 240D that sits a lot - after sitting 6+ mos, the gas pedal is difficult to push. Even if I squash it really hard, it seems to act like I'm barely pressing on it. I thought that maybe it would be the accelerator cable & I'd have to replace it(?) but I'm not finding it anywhere online & now I'm wondering if it has a different way to move the throttle linkage.

I can only get the car up to about 60 mph & if I'm going uphill it won't even do that. This is probably a very simple fix to some in this group but I thought turning to the wisdom here would be a good start for me.
