Bolt and lube ?'s from FNG

In trying to read the lubrication instructions for my SA M1A, the photocopied forty-year-old diagrams and text just ain't cuttin' it. So...

1. Can someone provide a quality diagram (exploded view would be nice too) of the bolt assembly?

2. What the heck is the "bolt [anti-friction] roller" and where is is?

3. What are some commonly available lubricants that can be used in lieu of the USGI "spec" lubes [if any], and if more than one is required, which ones go where?

1. TM9-1005-223-20, the M14 Rifle "Ordnance Manual" is a common gun show reprint and probably available on-line. This has quality diagrams and photos of the bolt. Since the bolt is based on the M1 Rifle bolt a diagram of the M1 bolt will serve well, other than the M14 bolt roller which is not replaceable without special tools and skills.

2. The roller will be obvious once the operating rod is removed and the bolt sitting on your desk. It's that thing that spins on the right locking lug. 8) The roller was a proposed M1 enhancement, but the production demands of WW2 delayed it until the M14.

3. There are several good, modern lubricants you can use. I use Tetra grease for "rifle grease" and CLP for "lubricating oil, general purpose." This rifle needs grease and oil, just like the M1. You need a copy of FM23-8 for the lube points, I'm surprised Springfield (Inc.) didn't include a lube diagram. But I didn't even get a manual with my M1A and when I wrote them about it I got a glossy catalog.....

Thanks for the input fellas. The images on the link are still a bit dark (as in my hardcopy manual) for me to truely understand exactly what I'm doing. I will attempt to follow as best I can, and also look for the natural wear marks to figure out precise lube points.

Lubriplate is also a very good grease and is semi-resistant to heat. It can be had from your local auto parts house. It's used to pack wheel bearings and such. I also have a pound can of military gun grease (yeah, I know. "This is my rifle, this is my gun,".....). I suppose that'll last me a lifetime.

Incidently, a testors model paint brush (1/4" wide) makes the best applicator I know of. It'll get just the right amount of grease in exactly the right places.

One last thing, you didn't mention it but if your rifles action and barrel is bedded, you won't want to break it down more than a couple of times a season. All the wiggling will loosen the bedding. Many folks only do a complete strip job at the end of the season so as to store the rifle for the winter months, completely clean, with fresh grease and oil.
