Now we're gonna jaw about "THE BEARING"!!

This issue pertains ONLY to a Scout II 727 tranny witha MARRIED transfer case.

The pic shows three different variations of a 727 tailhousing (and this doesn't even begin to cover ALL the variations that were produced!!).

On the left is a Dodge 440 motorhome tranny, this would be near identical to the same item found in some IHC motorhome chassis. Next to the Hemi version of the 727, the motorhome unit was the most rugged variation Chrysler produced and was the same unit found in medium duty Dodge trucks.

The center unit is what is found on IHC 2x4 Scout II, and all fullsize 2x4 and 4x4 vehicles (except motorhome chassis).

The tailhousing on the right is for a Scout II married transfer case...that is the unit previously discussed regarding the vent relocation project.

The Dodge and the IHC output shaft ball bearings are dimensionally identical. However, the Dodge unit is a "9 ball" bearing (higher load capacity), while the IHC bearing (that tranny is from a T'all)is a "8 ball" bearing.

BOTH of those bearings are "specials" meaning they are for TRANSMISSION applications only and are NOT a common off-the-shelf bearing from the local parts source. We DO have a supply of those bearings available (semi-difficult to locate) but they are pricee...currently around $78 new. If ya can't stop a leak at that seal point by installing a fresh one, then the bearing is NG!

Both of those trannys use a "bolt-on" yoke (not a slip yoke like Chrysler passenger car apps) and use a common single seal which is provided in any TF 727 "soft parts" overhaul kit.
