Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 threading new throttle cable

Excuse this post if it's been discussed before. I am installing a fan kit. The kit comes with a new throttle cable with an "angled end." I was told the easiest way to thread this would be to cut off old cable in the middle, tape it to new cable, and take the end of the new one (which attaches to pedal), and pull it through to the footwell. The problem is the hole is way too small to accommodate the threaded end, nuts, and cable end. What am I missing here? This is not "plug and play." The Morgan instructions do not say how this trick is done. I'd like to avoid soldering a new cable end. Am I expected to drill a bigger hole? What have others done? Including idea for new hole to make threading this thing easier. See pics of parts I am referring to.

I think drilling out the hole is the only option. I would like to hear what others have done, though?

Interesting. On my December 2012 machine the cable doesn't go through the plastic panel at all. Rather it goes up then forward, running between the top front frame tube and the body before going to the engine.

So in case any new owners are interested in this thread: the engine end of the cable (with 90 degree elbow) will fit through a 3/8 inch hole in the footwell wall. I was able to fit the drill in there and make the hole larger. I cut the old cable. From inside the opening over the footwell, I inserted the new cable and grabbed it from oil tank area side and brought it through to the engine (under the K brace as per instructions) and up to the engine. I took off the air filter assembly to have free access to the cable connect. My advice is attached the pedal mount end first, and then attach the cable to the engine side. Back to footwell: adjusting the two nuts that come with the cable is tricky. the below pic is not correct. there are 2 nuts you use to adjust the tautness of the cable. You loosen the bottom nut so it slides down the cable next to end (it is off the threaded tube entirely and loose with the cable end), slide it onto the mount (which has a slit for the cable), insert the threaded tube into the hole of the mount, and then you have bring the bottom nut up to the threads of tube and start screwing it onto mount. To get the cable end to the pedal (while pedal is in the total UP position) and THEN you can begin to tighten the two nuts.... Stand by for more posts. I will be getting a stubby 10 mm wrench for those nuts (one below the mount, and one on top). all the above was done in cramped space all done by feel.

I have been avoiding this job for months now even though I need a new cable. Because the gas pedal side looks like a royal PITA. Interested to see you pave the way for the rest of us in this thread....

Finished this job. Here are some pics of what I was dealing with. The throttle body-threaded end-- was all rusty seized up. and needed anti corrosion lubricant to loosen it. You have to do this by hand and it takes a god awful amount of time. And scraped knuckles. I bought some special wrenches to help get under there. the one on the left was the ticket. I was told not to tighten the cable too much as it messes with the auto idle. Pic of the final product (even though the fan shroud I bought was new stock from Morgan, it was scratched and denatured. Dealer is making it right by ordering me a new one). Fan kit is NOT a "plug and play" if you are dealing with a pedal assembly in the driver footwell that hasn't been touched or oiled or cared for. I will give another post to say if the throttle and fan works. I am using Emil's fan switch (not the relay that comes with it from factory. I will save that for next owner if they want to do the program at the dealer etc.). Mine has a 90 second relay which I turn on manually from the cockpit after a drive on a hot afternoon or a long traffic light.

Okay, upon test driving, it idles WAY TO HIGH. 2500 plus. So either: cable adjusted too tight or the fan shroud is interfering with something. I will attack it tomorrow: loosen the cable and give the gas pedal a good clean and check and make sure the spring makes it return to full up position.

Gave it 1/8 inch slack and now purrs at 1,000 rpms at idle. tightened everything, lubricated the gas pedal hinge bolts. 90 second fan relay works like a charm. I will consider this job done.

What did you use for throttle cable lube? Back in the day a molybdenum disulfide based product was what was recommended but what is the best today?

BTW, good thread!

thanks, Stephan! I did not use throttle lube as it's a new cable with Morgan kit. Please recommend what you think will work so we'll all know what to use when it starts sticking. I am surprised at the level of tech involved with the throttle. These cars are time machines. Wanna know what it was like driving in the 1930s? drive one of these.

The way you tighten the throttle cable is the same way you tighten the cables of your brakes on your ten speed bike. Anyway, I don't drive my car in the rain so I am dealing with modest humidity rust (from original owner who lived in Florida) and rust from me washing (oddly, the Harley Davidson rectifier bolts are not stainless steal so those are showing rust after only a few weeks). If there is a lube I need to consider, let me know. I imagine you would unhook throttle at the engine, tip the cable up, and spray down the cable hose? Mine does not stick or get bound up now so it's something I should prepare for later. I had the car out on a short sprint through countyside and performed really well. I have to say, the fan shroud limits engine noise a tad and so it's all grumble from the mufflers. And the 90 second relay is idiot proof. Turn it on after you're done with your ride. it shuts off automatically. but the main reason to get the fan kit I imaaine is because it funnels all that air past the back of the engine and looks so cool.
