    When I got my auction 1954 Fleetwin 7.5 hp, the twist grip
    would not turn. I thought it was just bound up from
    hardened grease or corrosion.
    After going thru all the parts, I put the tiller handle back
    together, and of course the twist grip throttle still
    wouldn’t turn.
    Inside the handle are two tabs that will slide into slots
    in the tiller handle….. why they’re there, I have no idea!
    When I get the twist grip screw inserted into the control
    shaft, the tabs remain in the slots in the tiller handle,
    hence "locking" the handle from turning.

    It would seem that I have either the wrong twist grip
    handle, or wrong control shaft.
    In the photo that shows it together, the right edge of the
    tape marks where the twist grip would have to be to
    get the bolt to screw into the control shaft.
    The twist grip is shown in position where it’s not locked….
    therefore, I have a control rod that’s 1/8" short, or a
    twist grip with the bolt hole in the wrong place.
    Am I missing something?
    Anyone else ever have this problem?

    I removed the fiber thrust washer that would make
    the control shaft longer, but then I didn’t have enough engagement
    in the gears.

    Perhaps the previous owner went crazy as well, and put
    it on auction!
    Your thoughts appreciated!
    Thanks.

    The tabs on the friction block are likely not aligning with the notches on your tiller.

    In your last pic, see the 2 cut outs straight down from the hole in your bar? There is another notch 180 degrees away on the other side.

    Take the white nylon friction block out from inside your tiller grip.

    Slide it into the tiller handle, aligning the tabs in the block with the notches in the tiller.

    Then slide on the grip and screw to tighten.

    If you are not using the tiller handle, (remote steer) you remove that white friction block. It keeps the throttle constant while using the tiller.

    It looks like the nylon friction collar is missing. You need one of those in the bottom of the handle. Part # 303282 Find one of those and put some grease in there and it should move much better.

    Gentlemen, It sounds like you’re saying the piece inside the twist
    grip with the two tangs is suppose to rotate. I had the tangs
    engaged in the notches in the tiller handle, but in doing so,
    I couldn’t turn the grip. I hope someone didn’t glue it
    in there! Will look at it again tomorrow. Thanks!

    P.S.- all shafts, gears, and mag plate turn freely,
    except for when I have the twist grip attached!

    Buc,

    The piece in the handle with the tabs should fall out when you tap the handle on the bench. If not, it is stuck somehow, and that is likely the problem. Get it free and it will work right.

    I just worked on the twist grip on my 1969 Johnson 6hp. It was very hard to turn and I had to use a bent pick to get a hold of the friction collar to remove it. I got it out of the grip, cleaned it, and applied a bit of anti-seize to the friction surface and put it back together. It works great now. I just hope the anti-seize doesn’t react badly with the nylon. It was the only thing that made it feel right. I tried grease, Vaseline, and light oil and none of those worked very well. It was in there dry and the spring put quite a preload on it when the screw was in place in the grip.

    Yes, that notched friction collar/washer is most likely stuck/corroded to the twist grip…You will need to fashion some sort of puller set up to pop it out of there…Your collar might be aluminum instead of plastic, clean it up and lube the mating collared surface with grease and your problems should be solved.
    The other common problem in this area is the throttle speed indicator collar. The collar gets expanded slightly and sticks to the twist grip making it tough to turn….Be sure to compress it down somewhat before installing to ensure it fits snugly to the tiller handle…

    Being an early model, the friction block is probably made of cast aluminum and is stuck inside the handle. If you can’t pull it out with a pair of long needle nose pliers, you’ll have to soak it in something first to loosen up the dried out grease. You want to be careful installing the screw to, it’s a non standard 12-28 thread and if you damage the threads, it’ll ruin your day unless you have the proper tap on hand.

    To install everything, I’ve found it easiest to position the tiller straight up and install the spring and greased friction block with its tabs aligned with the notches in the tiller. After aligning the flat inside the handle with the corresponding flat portion of the shaft, the handle can then be slid down over the block and spring and with a little bit of pressure and twisting action, it should fall into place.
