Leaf --- 8M6617 & 8M6618 P/O 8M6241 Spring Group - Original supplier went out of
business. Cannot find another supplier that can duplicate design so now these two springs
are straight - not curved on end. If dealer has curved style and one breaks, both have to be
changed.
8M6617 - Used to be flat for many years and as a deviation to print was written to ok
this. Since then we have gone back to original design. This will work fine in the newer
machines but in the older machines this will not marry up to the next spring 8M6618.

Studs
Make sure that heat treat scale on the threads on the 6V5699 stud does not
cause artificially low nut torques at assembly by creating thread
interference (galling). The use of 8M2296 nut with this stud will reduce
the thread interference.
6V5699 was discontinued because it was no better than the 4S6137 stud.
The new part number should actually be 9X2840, which is 3/8 X 16 with
rolled threads. It is also stainless steel. SOW 9-29-88
