I sharpied the bolts red. Also visible is the tip of the input shaft coming through it, and the snap on front seal retainer.  After the bolts come out, a special puller is used to remove it.  Pump on the bench  With the pump removed, the input and reverse drum come out as a pair. The band will likely give you grief, but a screwdriver will wiggle it out of the way. Notice the machined surface on the reverse drum. That is where the band clamps. In spite of the pic, it is in great shape. I will not be reusing it on this trans though, as I am installing a new drum for the extra wide band I am using.  The pic below shows the trans case gutted down to the front planetary set. Notice the band still laying in the case. At this point, the "input" side of the trans is ripped down. Now, it is time to remove the output side.  The sun gear pulls out, and there is a snap ring to be removed. After that occurs, the output shaft slides out and smashes your toes, and the front planet assembly is removed. Sun Gear:  Front Planet assembly:  The pic below shows the reaction shell, and the front planet assembly mocked up as it sits in the trans. The large outer ring is the reaction shell, or "cookie cutter". This will be replaced by "The Beast"  This pic shows the worn Reaction Shaft. The bushing located in the rear sun gear has worn this piece. I will be replacing it with a like new, used, $50 replacement piece. I will make oiling and bushing mods to prevent this from happening in the future.  |
