<VV> RE: Terminology

[Jim Corey]

Clark:

 

I absolutely agree with you.  However, based on the responses to my thread
about my diff problems, common usage differs from the "book" terminology.
What you call the "case" is often called a "crown assembly". The 61 shop
manual calls it the "differential assembly" (Rear axle 6c-8, Differential
carrier disassembly item 8).

 

I think part of the problem is many people grew up working on "cars".  They
tend to use more generic descriptions of parts.  Others have entered the
mechanics world car specific, i.e.  Corvair.  They tend to use the book or
manual descriptions. Just my thought.

 

It's oft been said, problems are often just communication.

According to the GM drawings I have here, the CASE is the part the ring gear
bolts to and where the spider gears live.  The CARRIER is the big part with
the tin cover on top. Also to further complicate the swapping of parts, the
distance from U-joint to U-joint on an early is less than the same
measurement on lates.  You can not use late stub axles on an early or early
stub axles on a late.  The late CASE with COVER is almost an inch wider than
an early. I recall the instructions on a 4-spider beef-a-diff kit say you
have to hacksaw off about a half inch of the case to use on an early car.
