Quadra Trac Advice

So I was rebuilding my front and rear drive shafts on my 1976 wagoneer. I drained my transfer case fluid, it was really dirty. I checked the slack in the Chain and came up with almost 1 inch of slop. Should I just replace the chain or throw in a part time kit as well? Don’t know how much if at all it would save in fuel. Can you drive a Quadra trac on hard surfaces with a part time kit? By hard surfaces I mean like between snow patches on asphalt. Also wondering with the fluid being pretty nasty should I risk the clutches being worn out? I drove it maybe 10 or 15 miles before I did the driveshafts. Thanks for any input you guys can offer on this. I have replaced chains on a Quadra trac in the past on previous Jeep’s.

If there's nothing wrong with the case, why go part time? Can you shift between full-time and emergency drive?

The chain just connect the two hubs in the case. I does not have anything to do with part-time or full time. If it were mine I'd change the fluid, add a new chain and drive it.

Suggest you read everything here: http://jubileejeeps.org/quadratrac/index.htm

I think everything is fine minus the Chain. I was just thinking I’m in there anyway. Wanted to know from those that have converted, the benefits fuel mileage etc. I have checked out this link. I saved it in my bookmarks, very helpful into understanding the Quadra trac. I have a few others bookmarked as well. I found one thread stating a 2 mpg decrease after converting to part time.

I did try engaging the emergency drive once, but couldn’t verify it’s operation either way. I was on a dirt surface and wasn’t stuck or anything like that.

Reports are that any mileage increase is negligible. I predict you'll never get back the expense of a part-time kit by savings in fuel. The Quadratrac full-time works really well, and you will like having it if you ever drive in snow, for example. And a part time kit has no effect on the longevity of the case, since all the power - rear only or front and rear - still goes through the problematic chain drive.

Post on fsjnetwork.com and you might get Flint's attention. He owns the page I linked above and is the guru of these things. I've been around them a lot but never owned one.

I would try the e-drive on pavement. Should be an obvious change - you'll feel the bind-up when you turn. Won't hurt for a short test at low speed.

Ok thank you very much Tgreese. I will give the emergency drive a test on a hard surface and see how that goes. If all goes well I will just replace the chain. Later on down the road I can do a part time kit.

Why do you want part time?

Well I was thinking less wear and tear on the front drive line etc. Better miles per gallon, that seems to be a myth or at least very little if at all. Unless I find something crazy I will keep it all time and like it is. It seems like at this point to only convert if you absolutely have too. Just wanted to bounce the idea off you guys and get your input. Thanks for your advice and input.
