QuadraTac low range unit Question.

I'm installing a low range unit on the back of my Q-Trac.The problem is how do I remove the drive slug for lack of a better term from the back of the non low range equiped Q-Trac.It's still in the Jeep so I can't see to good on how it is held in. [img]images/graemlins/confused.gif[/img]

Re: QuadraTac low range unit Question.

The planetary reduction just slides onto the back of the case so I would imagine the single speed spud shaft does the same.

Re: QuadraTac low range unit Question.

There should be a snap ring that holds it in place to the sprocket.

Re: QuadraTac low range unit Question.

Thats the problem I can't see what kind of snap ring it is, so I need to know what kind of tool to use to get it off.I really don't feel like pulling the case off if I don't have to.

I've got a spare single speed quadratrac sitting on the floor in the garage. I'll pull off the rear cover in a little while and post back with what I find.

Re: QuadraTac low range unit Question.

Sorry for the poor quality picture but it's the best my $20 camera could do.

If both of your driveshafts are still connected, you'll have to raise one front or rear tire (or one front and one rear tire if you can't overcome the limited slip in the transfer case). Put the transmission in neutral and make sure the transfer case is unlocked if only raising one tire. Remove the 5 bolts holding the cover on and remove the cover. Be prepared to catch a little fluid. Rotate the tire(s) until the slot in the drive slug is visible. The snap ring is inside of this. You'll have to spread the snap ring open at the same time you remove the slug. It's pretty easy.

For installing the low range, you'll have to remove the planetary part from the low range unit. Slid this on the sprocket where the drive slug was. Install the snap ring. Install your gasket or silicone. Now slide the low range unit on and bolt it down. Remove the transfer case fill plug AND the low range fil plug. Fill the low range unit with fluid with the transfer case fill plug removed too. When the low range is full, then fill the main fill in the transfer case.

Re: QuadraTac low range unit Question.

OK now it's time to laugh at me.I jacked up the rear axle to spin it to where I can see it.I grab ahold of it to look at it and it comes off in my hand [img]images/graemlins/chair.gif[/img].Then in less than ten minutes the low range unit is on [img]images/graemlins/cool.gif[/img].Thanks for your help and patience. [img]images/graemlins/40BEER.gif[/img]to WILL.
On a side note are the QuadraTrac's from the late 70's waggy's the same as the CJ units?I looked at a 79 and a 84 this morning and the 79 has a low range unit on it also.I can get both for $150.I don't know if they run but if they do it will be a nice bonus

Yes, the quadratracs used in the FSJ's in the 70's are the same Borg-Warner 1339 transfer case as used in the CJ's. The one from the 84 will not be the same. $150 for a quadratrac is about 3 times what I would pay for one. The ones that sell on ebay usually go for $40-$70. I've seen a couple with starting bids around $100 and the auctions end with no bids.

Re: QuadraTac low range unit Question.

WILL,sorry I wasn't clear.It was $150 for a 79 and 84 Waggoneers.That mean's 2 360's,1 T-400 ,1 TF-727,1 BW-1339,
3 Dana 44's,1 HD AMC 20 and plenty of spares for my J-10 project.The 79 has a good set of 31's with nice rims and the 84 also has a clean set of wheels.
I usually don't rush out and buy anything when I need parts because if I'm patient enough, rigs like these turn up. [img]images/graemlins/grin.gif[/img]
