Throttle Lift Solonoid

[LXIX SL Rookie]

This rookie is searching for an AFFORDABLE Throttle Lift Solonoid for our '69 280 SL, auto  trans. 

My M-B tech -- seemingly knowledgeable and competent, and definitely patient -- found one quickly through dealer/factory M-B parts sources -- for about what I paid for my first car! --  but he's been unable to find one yet through his aftermarket contacts.

It's part #000 072 0500 .

I'm OK with your rants, raves, and recriminations, but I'd prefer your ideas and suggestions ... Many thanks!

It looks like SLS has them for 260 euros -- which strikes me as reasonable. Of course, have no idea what exchange rate is today -- or shipping. In any event, I bet less than MB price...

Thanks for your quick reply, "J."  And with apologies for my ignorance, what's "SLS" ... Pete N.

[J. Huber]

Sorry Pete. Boy you are a rookie...

SLS is one of the SL parts vendors we tend to use here. They are based in Germany -- so the prices are in Euros. For that reason, many of us opt for U.S. based vendors such as (but not limited to): Miller's, Bud's Benz and K&K Mfg. A link to all of these can be found on the Home page here.

I like to use SLS's website for parts diagrams and as a price comparison to the stateside vendors. Sometimes, they have things others don't -- sometimes it comes down to price...  All depends. As a new owner, I would take a look at them all and get familiar with the way they operate. Personally, I like Miller's or yet another business -- Dave Gallon Restorations. You will find that there are many times where the MB price is higher than these guys. Not always -- so don't rule out checking with your local dealer or the Classic Center (again found in the suppliers list)... Good luck.

Very reliable, and usually good prices.

Hello,

You may want to find a good used one. They were used most of the injected MB 6cyl sedans of the era. You could buy the whole engine and trans for that money at your local Pick n Pull.

Happy Hunting!

Does anyone know how these were used, positioned over the 9 year production of the W113's?
Example: only used on automatics? Were they used if no A/C installed?  If A/C installed they only were activated when you would switch on the A/C?

Were these used on later 280SL's with no A/C?

Thanks,
Bob

Hello Bob,

They were originally used on automatics to boost the idle when the car was put in reverse or a drive gear. On the later USA cars they were used to boost the idle when the AC was switched on.  Not sure when the exact breaking point was.  It probably coincided with changes made with the injection pumps or the addition of the vacuum dashpot.


Some  cars came from the factory with the solenoid is present but never hooked up (eg. late USA car with no AC and vacuum dashpot).

Thanks Joe!

The reason I asked is that I dont have mine installed.  I removed it when I removed my A/C a few years ago, as it was only functioning when I turned on the A/C.

I also removed my dashpot when I had my injection pump redone by Gus at Pacific.  He performed the Bosch service bulletin adjustment which came out in '72 which sets the pump up so that the dashpot is no longer needed.

In summary, I am currently running w/o the dashpot and lift solenoid.

Hello Bob,

Sounds right to me. Less complexity is good!

.....this is getting to make sens now why my 1970 280sl runs and idles far better since I deactivatyed the dashpot. I arrived at that solution by process of elimination and up to now felt guildy of doing something that is a no-no.....I feel a lot better now......

CHEERS !
