Are they in Jerry Kuhnhausens Gas Operated Service Rifles book? I'd look in my copy but it is packed into a POD at present.

From DIFFERENT, who wrote the book of the History of the M14 rifle:

M14 extractor plunger spring: 0.48 " reference free length 12 coils

M14 ejector spring: 2.13 " reference free length 40 coils

M14 operating rod spring: 15.23 " reference free length 104 coils

References: USGI drawings B6008886, B7267959, and B7267079

IIRC, Ted Brown recommends replacing the operatng rod spring when it gets to 1 " less than its new condition free length, so ~ 14 1/4 ".

In my experience, the extractor spring lasts more than 5000 rounds but at 5000 rounds is when I find myself replacing the ejector spring. YMMV and HTH

A fired 30.06 case helps with disassembly/assembly of the bolt internals. Chamber the 30.06 case, the op-rod spring holds the bolt/ejector and extractor tight. Flip the rifle over and use a small punch to drive extractor stem out from the bottom of the bolt. Pull op-rod back slowly to capture ejector spring/stud.

Or, use a 7.62mm/.308 case. Both will fit into the chamber and the case heads are identical. This applies to both .308 and .30-06.

True but the 06 case holds the bolt farther out for ease of access.  I prefer to do it right in the gun with the longer 06 case.  The gun does the holding of parts.  

The garand chamber brush tool also does the same job.



I was going to upload a photo of the M1 and the M14 ejector and spring combos next to a ruler I just took but yea, brownells.
