How do you get it apart

O.K., I tried the obvious, removing the bolts , but that didn't work. I am trying to remove a Rancho overdrive from a D18 transfer case. Anybody able to tell me how?:?

Edit: Sorry about putting this question in the wrong place.

TIA,

 

Usually a snap ring in there that holds everything in place....and makes it difficult to remove. Search for the snap ring and get it out. Everything should come out then. Don't force it out!

 

Well, I have looked, carefully pried and peered, cussed, threatened it with the torch, I don't see any clip or how this is supposed to come apart :evil: :evil: :smash: :smash: If anybody has any knowledge of how to get the Rancho loose (or refer me to someone who does) from the D18 I would...... well I don't know what I would do but I would be very appreciative.

It does pry apart just a little but then it stops.

Don't know if this is the same for the Rancho model.

From Novak site:

If the Model 18 is equipped with Warn overdrive, it must be removed before the transfer case can be removed from the transmission. To accomplish this, disengage the Warn overdrive. Remove the shift linkage from the O/D. Remove the five bolts that hold the O/D to the transfer case. The four bolts on the back cover of the O/D do not require removal. The O/D housing can now be pulled straight back for removal. If necessary, the housing can be tapped back (while pulling on by hand) with a plastic faced hammer or block of wood. Be careful, the housing is aluminum and is easily damaged. Do not attempt to pry the overdrive off. Note that bearing seat constriction may prevent easy removal. In this case, remove the rear cap of the overdrive. Attach a slide hammer to the six-spline tube and tap it rearward. With the unit now separated, continue as indicated.

With the housing removed, the hub assembly is now accessible. Use a light to look in the hole in the center of the hub assembly. You should see a square shaped flat wire lock ring in a groove. A thin pair of long nose pliers can be used to squeeze the ends of the lockring together for removal. The lockplate (or washer, in common parlance) that was retained by the lockring can now be removed. With these removed, use a regular 1/2" drive socket extension to remove the special hub retaining nut. This has a regular right hand (counter-clockwise to loosen) thread. When the hub nut threads disengage, the hub can be removed from the output shaft.

The transfer case can now be separated by removal of the five retaining bolts. One is on the front side near the front driveshaft yoke.
