    Some Jeeps won't back up at all without the cable, just buck like crazy. Others don't seem to mind it. Definitely worth hooking one up if you don't have it. Will let the clutch live much longer with it installed.

    What does that cable actually connect to? The bell housing? Because there's nothing that looks anything like that under mine, 225/T14 at present. It backs up fine, it just isn't pleasant.

    Same here, but I've never noticed poor performance while in reverse.

    I wish I did have one. Mine bucks like a bronco in reverse. I have steep driveway. If I want to back into the garage, I have to put it in low range.

    Mine will occasionally buck backing up an incline. Never had a stay cable. Never did it prior to correcting the crossmember/t'case mount arrangement either. Interesting as those mounts were all wrong. Guess I'll fab up a stay cable.

    Fokker, I think I see the remnant of the bumper arm in your picture. Somebody cut it off for you.

    Visible in lower right corner of pic. "Engine stay cable assembly."

    This is flathead, but F-head is same.

    It is kind of like the torque mount on the side of the transfer case. You really don't notice it, but it is a very important part of the mechanical engineering of the vehicle. When a transmission or transfer case housing is broken or axle shaft twisted, what was the cause? Many people just simply don't know what they don't know about what they are driving.

    Now that I know what it is, I guess I should reconnect it and tension the cable. Is there an adjustment specification?

    FSM probably addresses it.

    I would guess no slack, but not straining tight. It's pulling against the rubber mounts, so I'd guess that it will never get really tight.

    My old '67 had one, my current '67 had one before the swap, my '48 has one, and my 59 has one...
    I just tighten it up "good 'n snug"..;)

    Would a '71 V6 have this? Mine buck's like a bronco in reverse, and I also have to use low range to back up my steep driveway. I can't find anything about it in my FSM.

    I didn't find any easy reference in the Service Manual either, so will include PeteL's illustration (see the word this imposed on the cable) and crawl under photos of a 1967 CJ5 w/225 V6 for additional visual clarity, and a random note.

    In my case, the e-brake cable (black w/yellowish band) crosses in front of the restraint cable. Also, in my case, the threaded end is not in a factory bracket (this is a T-98 conversion). The cable is sold to fit CJ2A 1945 - 1949, CJ3A 1949 - 1953, CJ3B 1952 - 1964, CJ5 1955 - 1971, CJ6 1956 - 1970, DJ 1956 - 1961

    From my random notes:
    Its purpose is to dampen out any clutch chatter. It should be adjusted just taut enough to remove any play--thumb pressure gets a little flex. The engine/trans/transfer is mounted on rubber and can move in relation to the clutch pedal, which is mounted on the frame. As the clutch is engaged, the engine assembly moves in reaction to the torque it is transmitting to the drive shaft. This causes the release fork to move in relation to the clutch, causing it to disengage. Because of this, the engine snaps back to its original position and the clutch re-engages. This cycle repeats itself very rapidly and is very noisy and violent. The effect is to prevent smooth clutch engagement. The stay cable damps out most of the engine movement without affecting the function of the rubber engine mounts.

    Is the bracket it attaches too bolted on? My cross member is currently out and I don't have that bracket but I have the thinner one out board of it and another on the front side that is completely different. I also have a hole in my bell housing with nothing in it right next to the master cylinder, which is where I assume that would bolt through?

    In my case, on 1967 CJ5, the bracket that receives the ball end is fixed/mounted in place with one heavy rivet.
