Managed to reassemble the OD end this weekend. It was amazingly therapeutic (to borrow a term from Mr. Milliman).
Started by assembling the
tailshaft and ring gear assembly to the Borg Warner OD housing. This went on with a pair of snap ring
pliers and holding my mouth
just right...
The
gasket (thank you shop manual) went on with permatex non-hardening. Followed by the
control plate and blocker ring...then the control plate
retainer...followed by the
snap ring for the retainer.
Then the
sun gear...and
planetary gear assembly...
The manual calls for a brass hammer to drive the
U-clips back onto the planetary gear assembly and the cam clutch assembly. When I hit it with a hammer, it just slid around. I used a small
hand clamp and this did the trick. No muss, no fuss.
With the U clips installed, it was onto the
cam roller assembly (seen hgere all slathered with assembly lube). Must admit that all the previous rebuild walk-throughs I saw on the OD were helpful here. I could not get the tail housing onto the assembly because the roller bearings were on the high end of the cam and the spring-loaded cage assembly was keeping me from rolling them to the low side. I finally gave in and tried the red and sticky stuff and it actually held the cam roller assembly in the low cam position long enough for me to slide the tail housing on (which has the bearing surface of the cam roller bearings machined into it). Plus one for Deve's website.
I made sure I set the
lockout rail spring (the end of which is seen here in the upper small hole of the tail housing) into to area between the bosses in the tail housing before proceeding. With the cam sufficiently slopped with heavy grease, all fell into place and we were in business.
Then the
speedo gear assembly...followed by the
OD Solenoid, which I
tested here...then the
governor switch, which I also tested using the procedure supplied by rfs56trk in a previous post.
All-in-all, with the picture-taking and fussing, it took about an hour to reassemble with moderate care.
I added the
side cover (sans gasket) to test the operation of the standard transmission and confirmed that
this end of the lockout rail shaft feature knocks the OD lockout lever mechanically to the "locked out" position when engaged by the reverse lever. So, the reverse slider gear lever travel kicks the OD out to prevent it from damaging itself when reverse is engaged. Cool.
Have to replace the speedo gear when the new one comes in from Classic Chevy. Not much point in returning the 60-year-old plastic one to it.
Onto the electricals next.
