Hand throttle write up with pics!

Ok so i had a few requests for a write up on my hand throttle on the ol YJ, so I figured why not, lets do a write up.
*****DISCLAIMER******
Make sure you consult your Jeep before making any modifications, think of it as a heart transplant, your Jeep may reject another random part once you put this on. And in all seriousness be safe with these, it's a liability issue if ever in a wreck.

1-BMX brake lever(I used an Odyssey Monolever)

1-BMX brake CABLE HOUSING(I used an Odyssey Slik cable)

1-Tandem bike CABLE(I chose this so i could be more flexible with routing the linkage.

1-hose clamp
i dont think i need to put a pic here......just use a small hose clamp.
1-Brake cable clamp from a bicycle

1-Barrel adjuster(used as a stop for the cable housing)

1-Jeep(use your best judgement here as long as its a manual)

1-roll electrical tape(to increase the diameter of the shifter itself for a more snug fit with the brake lever)

Ok and next post will be installation

Should've used the trigger monolever, and linear cable for less binding. Just kidding. Good to see a write up with pics though.

You can also use PVC cut in half and painted black to increase the shift knob diameter. I love my hand throttle too.

Part Two-the sequel

So on our first installment of YJ garage we showed you the needed parts for a hand throttle, In this episode we will be going over the installation and tools needed for such a job.

1-Knife(I used it to cut the shift boot a little, it was cold and it wouldn't stretch, you may not need to do this, but i was impatient)
2-10 mm wrenches(to tighten the brake cable clamp and cinch down the cable)
1-5mm allen wrench(to clamp the brake lever to the shifter)
1-Regular screwdriver(to tighten hose clamp)

Ok now that this is over, the install.
The first pic is showing the shifter, the brake lever, cable&housing, and electrical tape I wrapped the tape to form a nice tight seal with the lever to shifter

Once the brake lever and cable were attached I ran the cable and housing through the shift boot and up the firewall to meet with the stock throttle cable

Now this is where the barrel adjuster and hose clamp come into play
I will be making a plastic piece that holds the barrel adjuster to the main throttle cable to anchor it and clean it up but for mock up and test i just taped it on. Now apply your hose clamp and make sure the barrel adjuster is firmly attached to the main throttle cable, this will prevent sloppiness in the hand throttle and act as a stopping point for the bike cable.

From that point I ran the exposed cable through the factory Jeep cable anchor point and attached a spring like component(from a broke snap ring pliers)to the throttle body housing. Next was the cable anchor which was attached through the linkage adapter. I then ran the cable through the cable anchor,adjusted it, and tightened it down with the 10 mm wrenches.

Next is time to test!
ENJOY!

Call me a n00b if need-be but, what is the main purpose of a hand throttle? Just curious...

When driving a Jeep on or off road especially a YJ the ride is too rough to accurately use your throttle, plus it frees up a foot if you do any wheelin(which we do)

It really boils down to 2 basic purposes.

1) It allows you to bounce around off road & maintain a steady throttle by bracing your right hand on the shifter & operating the throttle with your thumb/fingers, instead of your foot bouncing up & down on the throttle pedal.

2) It acts like a "Kentucky Cruise Control" so you can rest your foot while driving long distances. I commute 60 miles a day in my YJ & it comes in handy for me.

Of course, the is the "cool factor" in the mix as well.

The reason I put mine on was so that when I have to start moving on a slope I can use the gas, brake, and clutch at the same time to keep me from rolling back. It helps especially when you have to pull someone up a hill so you don't roll back and jerk the strap a lot. They can also be used to rev the engine at a constant speed above idle for a compressor, welder, winch, or jump-starting.

Ok heres the youtube link for the operation of the lever, Sound is kinda bad but hope it helps to illustrate some of the operation

Oh and if anyone is wondering, i can still adjust the cable to make a constant idle for welding, winching, etc, just by adjusting the cable at the lever

Try starting on a hill with a manual transmission. One foot is on the brake, the other is on the clutch. A hand throttle just make life alot easier in those situations.

Ok, I figured it was mainly for trails and what not. Makes sence with a 5 speed to keep from rolling on a hill. Might just have to look into that.

You people and your hand throttles. j/k

Try a line lock/roll control, Also works as an "effective" e-brake on the trail.

It is also useful when winching, to keep engine rpm's up. This gets the alternator charging at a higher rate, reducing the load on the battery.
