cruise control 200 1993

I have a 1993 240 with the late model cruise control (with the separate vacuum pump). The system would not longer hold speed and I did a vacuum check. Quickly found that the system would not hold a vacuum. The source of the problem was a hole worn in the rubber diaphragm of the throttle servo. I tried a ghetto fix by using a rubber inner tube patch. This only worked briefly. I think there is too much flex in the diaphragm for the patch seal to hold.

Does anyone have a source for a new servo? I have found the same part but for Jag or Land Rover and the brackets/linkages are different. I don't want to buy a part at Land Rover prices only to hack it up with no real guarantee of success. Thanks in advance.

    Try 3M Super 33. You should have some in your toolbox anyway. The other electrical tape ain't worth a darn. 3M also has Super 88 but I've never used it so I couldn't say.

    I can tell you that I have used the 33 on those diaphragm lacerations. The repair didn't last forever but it lasted for a while. I too tried the tire pump patches. They stunk.

    Also don't forget to use that narrow protector piece when you reinstall the diaphragm.

      I don't have any experience using Super 33+ on diaphragms but I have to echo you on this. Once you start buying $5 rolls of electrical tape there's no going back. The plastic cans are handy for holding little odds and ends too. I want to say Super 88 is intended for "cold weather" so it may actually be a better application.

      Can't hurt to try one of these tapes, at $5 what do you have to lose? It's not like you won't use it elsewhere.
