an someone explain the ford 9 in rears??? I thought the pinion shaft is actually smaller than the 741 center for a 8-3/4 Not bashing just want to learn--Are the fords easier to work on or something???? Thanks Steve
I don't know much about them accept that the Pinion has 2 bearings on it that are supported by the Pinion Carrier. 1 on the backside at the pinion gear and one on the front side of the Pinion Carrier. The bearing races are facing opposite so when you assemble the Pinion Carrier and tighten it down and set the crush there is support on both ends of the pinion. The Pinion Carrier can be removed/installed as one unit to the Case with the Pinion assembled. There are a huge variety of parts available too. All parts are Cheaper than the 8 3/4, cases, bearings, gasket sets, gears etc. Not to mention all the different gear ratio's available. Unlike the 8 3/4 where we only have a few choices. Any gears under 3.55 for the 8 3/4 742 or 489 case will just about need to be purchased used because new ones do not exist. A well built 9" will take some serious power 1200++ easily. A back brace is usually required over 600HP because they tend to bend without one is what I am told.
