Chuzie's '77 Project

[chuzie]

So here is the deal as of today.
Yesterday I got a lot of the build completed after I resolved my issue with the Rev/High drum. I was able to add the 5th friction+steel by replacing the pressure plate with a .100 thick steel and reducing the size of the snap ring. My clearance came out to about .035 and am fine with that.
So on to the build progress.

Installed...
Parking gear and pawl
Sprag and roller kit and inner race (fun)
Low reverse band
Reverse clutch drum
Output shaft
reverse ring gear and planetary
forward clutch assembly and planetary
input shell
Input shaft
Intermediate band

Modified...
apply strut to fit the new rigid band
stator for the oil mod

Most of the installation items were pretty easy but it took a while because I went so slowly and lubed everything with Lucas Oil Transmission Fix which is thick nasty stuff.

One snag I hit was the sprag and roller kit. It took me a while to devise a method for installation. You can't just shove the rollers in their holes because there will not be enough room for everything. The trick is to install about 1/2 the rollers and then to get the other 1/2 in you have to compress the sprags both on the roller position you wish to install as was as those on the opposite side. This moved the opposite roller into the recess in the outer hub which makes more room for the inner race and thus the new roller. This probably makes no sense right now but I bet when you do one of these you will be like "oh, ok."

The new rigid band has a slightly larger tab to insert into the apply strut so I had to dremel a little out of it to make it work. No big deal and it worked just fine.

I also started on the stator mod. I almost got my butt kicked when removing the ball plug because I could not get it to pop out with the normal suggested methods. I ended up drilling most of the core out and peeling it out after a painful 45 minutes. The spring and one of the balls inside came out just fine and of course the second ball was pretty well stuck even though I was beating the crap out of the stator to get it loose. I ended up caping one side of the shaft with thick tape and wrapping my air gun with a sock to create a seal on the other side. Cranked up the PSI to about 120 and after a few strokes of the hammer and all that air the little SOB popped right out. Now I just need to purchase a 1/4" NPT hex plug and tap to cap off the hole and I will be ready to install the stator and pump and see if we have a decent endplay measurement. I also need to get my air checks done.




This is the Rev/High assembly bits and pieces. Notice I used the rough frictions rather than the smooth.


Reverse gear



Sprag and roller kit before inner race installed. This method did NOT work so I had to remove 1/2 the rollers and then insert the inner race and work the other 1/2 in one at a time. If you look at the outer hub (outer race if you will) you can barely see how the wall tapers out as the wall goes from the roller to the sprag. So if you compress the roller clockwise against the sprag you create more room.

progress as of this evening with most of the guts installed and ready for the stator and pump below.

stator and pump assy.. you can see the hole on the outer diameter of the stator where I drilled the balls out. I will plug it up tomorrow. those are the handful of selective #1 washers I will use to get my endplay clearance correct after stator and pump installation.

I fly tomorrow so I doubt I will get much, if anything, done. Chuck, I need to coordinate with you to get hold of my jack stands and your tranny jack. I have hand jammed the tranny in this rig a few times and it is not even remotely fun. A jack would be most appreciated. :xyxthumbs:
