Re: Information needed on Quadratrac 4WD System

i've had mine for six years now. i've replaced the chain twice. i get about 40k miles from a chain. they aren't that expensive and can be replaced in a couple hours. i like the versitility of the q-trac too. on the street i unlock the hubs and lock the transfer case. off-road with the transfer case unlocked and the hubs locked, the locker in the front doesn't make it that difficult to turn. with just a turn of the vacuum switch it's locked up like any other transfer case. without lockers, the full time is more stable on the road than a rear wheel drive cj. just some things to think about.

Re: Information needed on Quadratrac 4WD System

[img]/wwwthreads_images/icons/smile.gif[/img] You can make a small modification to the QT which will increase it's ability to please you immeasurably. If you disable the cone clutches it helps the Jeep run freeer in all wheel drive and enables you to pop in and out of lockup much easier. It also eliminates having to use special fluid, makes the chain last longer and improves gas mileage. What you are doing with this mod is approaching the modern style 242 transfer case which has 2WD, 4WD(locked), 4WD(unlocked), and 4WD Lo Range; a very versatile and well-designed setup.[img]/wwwthreads_images/icons/tongue.gif[/img]

Re: Information needed on Quadratrac 4WD System

[img]/wwwthreads_images/icons/smile.gif[/img] It's pretty easy to disable the cones. All you do is machine the splines and the small register out of the existing cones, and then install a thrust washer between the side gear and the cone to take the rotation. By doing that, you free up the center differential to actually differentiate, and the Jeep can run without binding. THEN when you go to "LOCKUP" (Emergency Drive)for balls-to-the-wall FWD, the open differential will allow the sliding lockup collar to latch up easier and more definitely. You can usually find spare QT differentials laying around that have been taken out when the case was converted to part-time drive.[img]/wwwthreads_images/icons/crazy.gif[/img]
