I just bought a 85 cj7 and it came with no manual...How do I engage the 4 wheel drive?...I was also told be someone that to never engage 4 wheel drive on dry surface because it could damage jeep, is that true?

Short distances on dry pavement aren't too bad, but prolonged use will cause the tranny and transfer case to bind up, possibly damaging them or the U-joints. It's also extremely hard to get out of 4wd after driving on dry pavement. It helps if you back up a ways to relieve the stress on the driveline. Not sure about Jeeps, but on my old Toy 4x4, the front wheels turned 3% faster than the rear to help the rig track properly on slick surfaces, which is why they tend to bind up when they have good traction.

Though I'm not familiar with your year of Jeep, it should be pretty much the same as mine to get into 4wd. Yours may have manually locking hubs, though. If that's the case, turn the hubs to "lock", then pull back the 4wd shifter to either 4-hi or 4-lo, whichever you want to be in.

Welcome to Jeepz!! Glad to have you aboard. We've got a lot of very smart Jeepers here that can help you with pretty much any question you might have, so pull up a chair and stick around a while!!

Does it have "Quadratrac"? IF so it is full time 4wd

Quadratrac was only offered 76 through 79 on CJs. I believe you need to throw the transfer case shifter when travelling at slow speeds (5mph or less.) I don't think any CJs came with a transfer case that can be engaged at driving speed like newer Jeeps do.
