I would be kind of hard to get a pic the way it is situated to the pedal, let me look in my manual and see if there is a pic of the mcor rod. There are 2 studs on the pedal side of the rod, one will show wear, thats the one to put a piece of tubing on. About a 1/2 in. piece of tubing, i am sure it can be done with out taking anything apart. If you look through the slot on the floor board from the top, its the top stud.

JRAY maybe you did what I tried and that is to shim the MCOR rod that hooks to the rod connected to the pedal assembly? Now that doesnt even make sense to me??
The rod that comes from the ( pedal ) has a flat plate on one end with 2 holes drilled through it, that in turn meshes with the MCOR splined shaft that has a flat plate on it
( BUT 2 rods ) sticking out that go through the ( pedal ) plate with 2 holes drilled through it? THESE 2 RODS ARE WHAT I SHIMED TO RESTORE TRAVEL.
STILL SOUNDS STUPID BUT CORRECT??
This was on my 1996 so maybe there is different types as mine, I think is older style yet.
Make any sense to you, or am I going about it all wrong? In my case its helping for now until I replace with new style MCOR and required shaft changes.

Mine must the newer style? 02 iq cart. I found a pic of the rod in my service manual, don't know how to post it on here. On the pedal side of the rod is a flat plate with two 1/2 in studs, other end is splined to go into mcor, the studs go on either side of the pedal arm. Clear as mud right?

I looked at parts catalog for newer models and found what you and I were talking about is very similiar at connection end. This is where I found my wear and shimed it to inprove travel. I tried bending the studs but couldnt get enough to do any good without chancing breaking them off. Next time Im under I will look at putting tubing on like you did. Not under very often as it takes a hoist to get me off ground anymore. Have neighbor that when able will do my crawling for several of us in park.
Like you I dont know how to post parts pictures so we will have to depend on our brains? My 76 year old one isnt too good?

The throttle linkage slack is VERY important!

Yesterday afternoon, was testing my new motor and controller via GPS and was getting only 21-22 mph, not much reward for spending $1,100.

While fiddling around, I again noticed the pedal slop and this thread. The pedal was going down at least a third before anything happened. I also remembered from this thread or maybe another on this forum that one guy fattened the stud with a tie wrap. So, I did the same. See photo:



Golly! On the next test run, we were pulling 30 mph. I couldn't believe that an eighth inch of plastic could make that much difference. I don't expect the tie wrap to last very long and will replace it with something like a hose clamp soon.

Thirty mph is too fast for a cart. Using a laptop, I've programmed it down to 24-25 max using only 65 % of the controller's output.

My next cart project will be to check and maybe repair the brakes. pjs

Thanks for the pic, that is the stud i fattened up with a piece of vinyl tubing. You are correct it made one big difference. That whole rod , shaft whatever you want to call it a piece of cheap a$$ed pot metal.

That's the culprit. It's a design made to keep the cart from reaching full throttle easily. Most golf courses that rent these things could care less if they perform to the max. Golf course owners also don't want a cart that is easily modified to run a lot faster than it should. The solution was to create a throttle that is not easily modified and does not quite get to full throttle. I think a new design modification is warranted here to get a good quick and responsive feel to the throttle and also assure that full throttle is being reached. Even with the added thickness you still have that huge distance that the throttle must be moved to just get the thing going.I would like a throttle that disengages the brake in the first 1/4" of movement and at that 1/4" begins to power up the motor. Full throttle should be reached in a controllable distance but not as far as they have to be pushed now. Have you guys ever noticed the small amount of travel (in degrees) that the MCOR actually moves? Not much.

Just for chuckles, I may grind to flatten the rear stud where it makes contact with the pedal to give room to add an even bigger spacer on the front stud. pjs
