Here is what the book says about this... (long) illustrations will follow...
Disassembly
1. Remove the snap rings by using pliers. If the smap ring is stuckin position, remove paint from the hole in the yoke or tap around the edge of the bearing lightly with a mallet.
2. Hold the universal joints with one hand and tap the yoke lightly with a mallet or a copper hammer. fig 4-12
3. As the yoke is tapped, the needle roller bearing cap comes out gradually, permitting easy removal with hand, as shown in Fis 4-13.
Reassembly
1. Apply molybdenum-disulfide grease to the bearing cap inner surface. Install the needle rollers, then install the oil seal.
2. Assemble the spider to the yoke and then inser the needle roller bearing cap into the hole by using a wood block and a hammer or a press as in Fig 4-16
3. When the bearing cap is in position, select and install snap rigs of suitable thickness so that the end play of the spider pin is held withing .004 inch.
a. Install a .059 inch snap ring inn the groove on one end.
b. Select the tickest snap ring wich can be fitted into the groove at the other end. Snap rings are avaiable in .057, .059 and .061 inch.
4. Repeat the same procedure to reassemble the spider on the other end.
I left out the section on Inspection. Let me know if you want that.
Here are the drawings...might need to make the image box bigger when it pops up to be legible...
