coolwind57 Posted August 24, 2018 Share Posted August 24, 2018 Working around my master cylinder, I heard a snap. Check out the pic. This plastic pieces I'm pointing to appears that it should be a single piece with spring inside giving tension. in other words, I don't think we should easily be seeing that spring. I've been driving with so far zero effect. Accelerator pedal seems fine like nothing happened. The cable seems secure when I work it back and forth. What exactly does this device on my accelerator cable do? Link to comment Share on other sites More sharing options...
hakukamana Posted August 24, 2018 Share Posted August 24, 2018 Do you have cruise control?, it appears to be the servo cable for the cruise control. It has a connector that connects to the accelerator linkage. It would not effect the normal accelerator function unless it were to start binding. It is engaged when the cruise servo is energized, and vac is applied to the servo, the servo will pull on the cable linkage and maintain, increase or decrease, based upon the commanded functions, from the stalk switch or the brake pedal.

coolwind57 Posted August 24, 2018 Author Share Posted August 24, 2018 No, I have no cruise control. Never did as far as I know. Certainly no provision for it on the turn signal stem. Link to comment Share on other sites More sharing options...
coolwind57 Posted August 24, 2018 Author Share Posted August 24, 2018 But what you're saying makes sense, hakukamana. Perhaps they put these type of cables on all Jeeps with only some having cruise control. By the way, you getting some major rain yet? I hear you island guys are fixin' to get hit pretty hard. I have a buddy on Molokai. Link to comment Share on other sites More sharing options...
hakukamana Posted August 25, 2018 Share Posted August 25, 2018 Hilo got hammered, the rain is still falling they got over 3' feet of rain so far. Major washouts, landslides, road closures. I live on the Kona side, did not get much of anything, no wind, very little rain, but the entire state took (2) days off. What does that cable attach to? If its a servo cable there should be a black can up by the cowl over by the pressure bottle. The cable would be the servo control cable for the cruise. Cruise control is a hit or miss, lots of parts and everything needs to be functional. One part fails and the whole system is shot Link to comment Share on other sites More sharing options...
hakukamana Posted August 26, 2018 Share Posted August 26, 2018 Coolwind I double checked my rig, that your accelerator cable from the pedal, if you trace it back goes through the fire wall and has the cable with the small plastic retainer that goe through the hole on the back of the pedal bracket. It looks like it got brittle and cracked, Cherokee 4.0 probably would work if the same length. Sorry for the miss information. Needed to be responsible and correct the bad data.

SVPete Posted August 27, 2018 Share Posted August 27, 2018 Mine broke where it passes through the bracket. No ill effects either. Maybe I'll epoxy it together one day.....if I don't break the retainer off too. Link to comment Share on other sites More sharing options...
91Pioneer Posted April 24, 2023 Share Posted April 24, 2023 What a useless thread title.... that's certainly not helping anyone find this thread when searching... Anyway, my 89 has this issue and I need to pass an inspection so I think I need to fix it. Have you guys tried epoxying- JB welding the thing back together? I realize it functionally doesn't really do much but I want to fix mine before I take it for an inspection just so it's one less thing to be concerned about. I'm thinking of removing it, clamping in a vice, and epoxying it back together while the spring is compressed. Thoughts? Mine is broken the exact same way, no cruise control.

pizzaman09 Posted April 24, 2023 Share Posted April 24, 2023 What that spring does is prevent the throttle from being jambed hard open if you push the pedal past 100% throttle open. With the way that broke, it will have zero ill effects as it will actually still compress the spring when pushing the pedal past 100%. The only thing that might concern me is if the cable flops over and starts pulling at funny angles and gets bound up or wears out, I'm not sure that would happen.

91Pioneer Posted June 5, 2023 Share Posted June 5, 2023 I thought I'd post a followup in case it helps someone down the road. I wound up taking my accelerator cable off and seeing if it could be glued or fixed but the plastic was brittle and kept breaking. I wound up buying a new ATP Y-296 cable and it fit and works perfectly. I had got another one from the junkyard but it was too short. For my 89 MJ 4.0, you want the slightly longer version of the cable. If you have this issue, measure yours before buying. Link to comment Share on other sites More sharing options...
Salvagedcircuit Posted June 5, 2023 Share Posted June 5, 2023 Good to know I try to put the gloves on and soothing music whenever I move cables near the throttle body. So much old brittle plastic Link to comment Share on other sites More sharing options...
