Clocking Axles

[HoupS]

Tell me if I have this right..... The gearbox is at 0 deg.. clocking it 20 deg. you would rotate the axle in (motor closer to the ground)? If it is the other way, doesn't that hang up and/or put more stress on the steering links?

What is the maximum amout you want to go or not go over? Should both the front and rear be clocked the same amount?

i clocked mine about 15deg. in the front and i didnt move the rear so far working out pretty good.

I thought Clocking was just to relieve the pressure on the U joints. (Shafty) How does this benefit MOA rigs?

You could be right...... I have no idea, I just did the mod, lol!!!

Clocking the front axle back has 2 advantages. The first, and easiest to see, is that the heavy motor sits lower, bringing down your center of gravity. (Fellow 540 club members take note).

Next, is the unique steering quality it creates. It gives the wheels a slight caster when steering. You know when you drive up to a vertical wall with your steering at full throw? The front of the tires make you go straight up. only the BOTTOM of the tires have steering.

As you can see bellow, steering caster leans the tires over a bit, giving you steering even when approaching a vertical climb with the front-most of the tire.

AWESOME, thanks dude, I appreciate the info!! I know exactly what you mean about a going up a wall, and the rig went straight up. I have 25 deg. on the front and 20 on the rear. Should I keep the rear clocked or level it back out?

[The Jackalope]

Might as well keep the back too. keeps the weight nice and low.

try this test;
with the 4wsteer on, turn the knob and see how the chassis rocks side to side. If you can live with that while crawling, keep it!


Mine is clocked about 16 degrees front and 9 degrees rear. but thats more for link clearance front, and underbelly clearance at the back. I'm aiming for 20 up front again, like when that picture was taken.

Dude, now that you mention it..... I use that to "wiggle" the rig coming down steep angles over rock or whatever. It works good for when I don't trust myself with a smooth trigger finger.

Hahaha that wiggle has saved me a few times

Sweet, I'ma do it! thanks for the info Jackalope.
