General Motors Part # 14066235 Clutch Release Fork

  I have a New "235" clutch release fork and a
used fork with 340278 stamped on it,and the only
difference between the two that I can find is the
"278" is 1/8" longer. GM lists the part # for the
340278 fork as 14066235. And aftermarket
manufactures like Dorman have one fork with
both GM part #'s listed on the box. This is some
times called the Heavy Duty Fork, because of the
thick material it is made.

Measurements
The "235"fork measures 10 1/2" from bearing
end tip to center of push rod pocket. It has a hole
on the side rail for the return spring and one hole
on the opposite side for a return spring bracket.


Wings & Spring
This is one of the reasons for this fork to be called
heavy duty. The throwout bearing and fork retention
spring is a standard and typical part # 1349163.
