Rochester Air Rifle Disassembly, Part 1

I was offered a deal on a pile of Rochester Air Rifles, so here I go with some more airgun insanity…

12021001

Rochester #1. Based on the Crosman 101 but somewhat different…

12021002

Somewhat ugly, to my eye.

12021003

“ROCHESTER PRECISION AIR RIFLE ROCHESTER NEW YORK”

12021004

Hammer setup just like the 101.

12021005

The bolt is nice.

12021007

Three more Rochesters…

12021008

Pile of parts. Before you ask, no I’m not parting any of these out. The plan is to get all four rifles functioning, and possibly a fifth…

12021006

Rusty buttplate

12021009

All the stocks have splits…

12021010

Buttstock removed.

12021011

Interesting fiber(?) washer between the head of the stock screw and the stock.

12021012

Removing the trigger guard assembly.

12021013

Two pieces.

12021014

Trigger/sear spring.

12021015

Barrel band has two screws on each side.

12021016

Removing screws.

12021017

The band slides back exposing the pivot pin.

12021018

Four screws.

12021019

Pushing out the pivot pin.

12021020

End plug and pin.

12021021

Barrel band just hanging around.

12021022

Pump arm and pump plunger removed.

12021023

Link pin is riveted and I’m not going to remove it. Notice the lack of a tension spring – none of the rifles had one.

12021024

Pushing out the link pin.

12021025

Adjustable length pump plunger.

12021026

Plunger assembly. I need to make a small spanner (or use snap ring pliers) to get it apart.

Much more to come…

  2. Nick, I have one of these Rochester Precision air rifles. Did you ever separate the soldered joint? They all have it. On the interesting fiber in the butt stock, I believe this is spare parts for the pump piston.

    Thanks for the post.

    shows the desoldering.

    That's awesome about the washer - didn't even occur to me. I'll have to check and see which guns have it.
