With the transmission out of the ranger. I removed the slave cylinder and discarded. I figured I would replace it, clutch, and flywheel because I had it apart and age. These were all original. I removed the shifter assembly cover and tailshaft housing. Make sure its in neutral before tearing into.
The transmission looked pretty overall however, I purchased a full rebuild kit and tried to replace as much of the components as I could.
Remove the top most piece on the output shaft - black plastic bushing, then remove the snap ring to get the speedometer drive gear, there's a small steel ball that under the speedo drive gear watch for it.
Then you need to lock the transmission in first and third gear, push the bottom ring down and push the tip ring up. The main and countershafts will not turn. Next you need to remove the locknuts from each shaft. You need to pry the staked area away from the shafts. I used a cutoff wheel to take material away then a awl and screw driver.
then remove the nuts on the countershaft (32mm) and output shaft (55mm) I had a 55mm wrench, I work in the wind industry.
Then remove the reverse idler shaft. Remove 14mm bolt on outside of case.
Then use a bearing puller to remove the output shaft main bearing.
Then remove from the output shaft the reverse gear, sleeve counter reverse gear, two needle bearings, reverse synchronizer ring. From the counter shaft remove the thrust washer and split washer.
Remove the fifth /reverse shift rod holding bolt - 12mm.
I will post again with more info.
