Lyman 450 parts question

[oscarflytyer]

I have 2 Lyman 450 sizers I bought used. Would like to replace a few minor parts. Basically the cross bolts/pins in the handle mechanism. And new O rings.

Can anyone confirm that the parts for the 4500 are backwards compatible with the 450s? Thanx

I used grade 8 bolts of appropriate size.
Also made up new handles.

I did what CW described.

Grade 8, here, too.

The 450 and 4500 use the same O-rings, and they can be found in a hardware store's plumbing section.

Some years back I was bringing a 45 lube sizer back to life. The machine did not take O rings but the new O ring pressure assembly would fit. I go along with the hardware store suggestion. Missing O rings here are up for resupply. Ace hardware here also has "gun screws." I'll take
along some scope rings for missing screws..
