Lyman 450 Luber sizer. Question

Boolit Master Join DateSep 2009LocationArizonaPosts770

I bought a used 450 at the park and swap a couple of weeks ago got a really good deal I think $20.00. The shaft was bent and the whole thing was really kruddy It cleaned up nicely. I ordered a new pressure screw assembly and got it yesterday. In the parts assembly on the shaft there is a nylon bushing, my question is what function does it have? I called Lyman and the service department said I don't need to use it. I am wounder though does it help in any way to use it?

On the shaft above the piston? What is the diameter of this bushing? None of mine have this. All that is in mine is the piston with two O rings on it.

The first result here is a .pdf for the manual which includes a parts schematic. It shows exactly what mine has ... two O-rings. I'd say the "spacer" is some kind of packaging stabilizer ring or similar to prevent parts loss.

The bushing is about 5/8" in diameter and about 1" long and located under the pressure washer. The hole in the center is a couple of thousands larger than the threaded shaft so it slides up and down with little drag. It was packed in a loose plastic bag inside a shipping envelope so I don't think it was for stablizing. I will probably end up not using it as it takes up a little space in the lube reservoir.

Well dah! I found it on the Lyman web site. It is called a Nylon piston stop coller. It is shown being used on the 4500 but not the 450. I think it is to prevent over tightening the pressure washer when the luber runs out of lube. I probably "will" use it as a safety measure.

Wish I could find a Lyman 450 for 20 bucks....

The parts diagram for the 4500 shows that as the piston stop collar. It is not shown on the parts diagram for the 450. I serves to prevent the piston from coming off the threaded portion of the pressure screw. Perhaps someone can post pictures showing the difference between the 450 and the 4500 in this regard.

If you get your shots in the black, the 10s and Xs will take care of themselves.

Wish I could find a Lyman 450 for 20 bucks....They are out there; I got a gray one at a gun show for $20.00, missing the lube piston. I also bought one of the orange ones that had the handle upgrade and heater at an estate auction for $7.50.

I think the key is that no one else knows what it is.

That is an excellent little part as it prevents the pistol from coming off the pressure screw . Without it it can be almost impossible to get the pistol out of the machine.
