crawler tech in a puller?

[gooba]

hey guys im building a pulling/show clod to haul my 3 crawlers from the truck to the rocks but im having a few issues first i need a hitch to hook my trailer too but the biggest problem is the suspension and gearing. right now the truck i literally a stock clod with oil shocks and stock motors. i dont really want to alter the wheelbase much cause it matches the stock hard body very well(remember looks do count in concourse which this truck is a regular in) but i was wondering if i couldnt put some crawler tech into it. what gear reductions are people using on clod axles besides the thundertech ones. the main problem i have is wheel hop and lack of suspension movement over the trail to the rocks. i locked the rearend already for more traction which helped but i still get a lot of wheelhop and on gravel and small rocks it 3 wheels horribly and is hard to keep straight and under control. if anybody else has a similar truck and can help or if anybody has ideas your help would be appreciated

Show trucks suck.

Wheelhop is caused by shitty stock suspension. A 4link will fix that.

Show trucks suck though.

9t pinions can help your gearing. Lathe motors can also help the low end. I havent seen a stock clod in years..so I dont rember how crappy the stock set up is (not that I want to either). Maybe oil shocks....piggybacks for looks?

lock the front axle. for a hitch use a ball bearing on a piece of round stock

lock the front axle. for a hitch use a ball bearing on a piece of round tapered stock

hey guys thanks for the info i had today off and it rained all day so i locked the front. ive heard about using lathe motors but cant get enough info on them whats the torgue like im used to mags so a comparison would be good. and sr5 show trucks do suck which is why this truck hauls the trailer and plays in the mud quite a bit

Lathe motors have more torque than MMs. The run times are also awesome. No good with mud though, they have no RPM unless you get 14V to em.

If your looking for torque go for the Lathe motors. They would be plenty fast for pulling your trailers around, it's not like you are racing anyone right?

lets get some pics

He mentioned mud though. Lathe motors are not fast enough for mud. They'd be acceptable w/ 14.4V in em though.

I just looked up the Lathe motors, and think I maybe should have bought those instead of my magnetic meyhems... Will the Lathes get longer run times as well as more torque?

First post, awesome site

[JasonInAugusta]

Yes.

The higher the number of turns, the less amp draw and longer run time.

BTW, welcome!

Tahnks a lot, geuss I got my first item for the christmas list...

Also, I started out with a chassis based heavily on the Mudcow, but I just found this site yesterday and think that a chassis like the one TerribleOne built makes more sense... Are their any advantages to cantelievers? Sorry for using your thread gooba.

Thanks a lot.

cants suck. just use the shock to link set up.

Wow kid... great addition to our tech dept! Damn...


badtodabone, Please explain why a cantilever setup sucks, that is if you even know..do you?

[badtodabone]

no not eaxactly. That is why i didn't make my self look stupid and make up a reason. toyo can you explain it to me real slow? I have trouble understanding things.

You're the one who stated cantilevers suck...

I would rather have shocks on the axles to the frame, or on the links to the frame, the only downsides to cantilevers are more moving pieces, less dampening (May or may not be a downside), and a minimally higher COG, you can get more travel out of a smaller stroke shock though.

[badtodabone]

I know. I said tht because i heard other people talk about how they suck

[toyofast]

On a Clod they might work fine but on a shafted crawler they can tend to allow the truck to "unload" too easily. Which will cause an early flop.

A shafted truck transmits too much drivetrain forces to allow a cantilever system to really work properly... at least in my opinion. I ran a cantilever setup on the 'Tot back in the day and on flat ground it worked quite well, it was once it was on a side hill and it'd just act like a limp "Oscar Meyer" when to much throttle was applied.

A Cantilever setup can allow free'ier movement throughout the suspension travel though... mostly due to more rod ends/joints flexing and lessening the binding issues. Almost any cantilever setup will net a 90*+ articulation.







I did like my cantilever setup but I had to progress to the next stage in my crawler....

Then let those people speak for themselves.
