TM:

(c)Clutch Shaft and Gear (fig. 21)Replace the clutch shaft if the splines or gear teeth are chipped or worn, if the gear has any teeth missing. Check the diameter of the pilot end of the shaft. If the diameter is less than 0.625" replace the clutch shaft. Replace if the clutch gear if it is worn or has any broken teeth.

OZ: The clutch shaft GPW 7761 and gear GPW 7762 are in very nice shape with greats markings. Unfortunately the shaft mikes to 0.623" which is 0.002" out of tolerance.

TM:

(d) Output Shaft Bearing (fig. 21) Ball bearings with loose or discolored balls or with pitted or cracked races must be replaced.

OZ: The bearing 7719 and snap ring 7783 will be replace as a matter of rebuild practice. The bearing is a New Departure 3206. The Parts Lists shows it as a ND 3206, so this appears to be the original bearing. It does not roll smoothly, it ratchets in the race after cleaning. REPLACE

(3) INTERMEDIATE GEAR ASSEMBLY (fig. 25). ‘Replace the intermediate gear if excessively worn, or if any teeth are damaged Check
the thickness of the thrust washers. If the thrust washers are less than 0.093" in thickness, replace them. Check the diameter of the intermediate gear shaft If the diameter is less than 0.750", replace the intermediate gear shaft. Replace the roller bearing, if the rollers are scored or have flat spots.


OZ: The Intermediate Gear 7742 is in really great shape. No wear and nice marking. Teeth are bright and neat. The shaft 7743 is worn slightly below limits at 0.0749" and has some minor pitting: REPLACE

The Thrust washers 7744 are one at 0.092" and one at 0.094". I will probably replace these.

The roller bearings appear to be in good shape, but I will replace these also to keep everything fresh. No sense scrimping when all other bearings will be replaced.

It seems like this build is keeping you busy, and it looks like it will take you some time to finish it.

I'm still splitting my time between finishing the home and doing other projects. I have a few parts on the way to finish the trans, and need to order all of the parts for the transfer case. Posting all the images takes a lot of time. It's a fun project.
