Baikal IJ-22 Air Rifle Disassembly & Reassembly Notes, Part 3

Almost done…

05221139
The piston seal screw has seen better days and is a replacement. The seal looks good.

05221140
Piston face.

05221141
That screw is wrong, I’m surprised it even held on at all.

05221142
Seal parts.

05221143
The breech seal is ok.

05221144
Notice the barrel is a rifled brass liner.


05221145
I found a good candidate for a replacement screw, but it needs a shorter head.

05221146
Chucked in an arbor.

05221147
Faced flat.

05221148
A replacement spring, two less coils, same diameter wire, a lot less curvature… Then reassembly just as disassembly, in reverse. I lubed everything, lightly.

05221149
Again, note the need to rotate the trigger block when assembling.

05221150
Closed.

05221151
Just for posterity.

05221152
The butt plate. Note it says IZh (in Cyrillic) rather than Baikal. I wonder why we call it an IJ-22? Just a Blue Book oddity, or some romanization of Cyrillic?


The rifle shoots! Quite powerful for its size although it may be dieseling a little due to the fresh lubes. I still need to sort out an issue with the rear sight, chrony it and check accuracy. I may lightly refinish the stock, or just re-oil it, not sure yet. I really love this rifle. More to come, later on.

Baikal IJ-22 Air Rifle Disassembly, Part 2

On I go…
05221117
The action in the spring compressor.

05221118
Punching out the rear pin.

05221119
The trigger block rotates to clear the detent.

05221120
Removed.

05221121
Think the spring is just a little canted?

05221122
The cast piston.

05221123
Cocking lug and sear.

05221124
Leather seal.

05221125
Barrel latch.

05221126
I love seeing a lockscrew on the pivot screw.

05221127
The latch.

05221128
Spring loaded!

05221129
Latch parts.

05221130
You can see the top of the trigger through a hole in the block.

05221131
Trigger unit.

05221132
One spring not to lose.

05221133
Trigger spring.

05221134
One pin pushed out. The pins are tight but not too tight. Light raps of a 4 oz. ball peen hammer did the trick.

05221135
Parts.

05221136
Trigger pivot pin.

05221137
Careful not to lose that spring!

05221138
A simple trigger, but robust! There was no lubrication anywhere.


More to come…

Baikal IJ-22 Air Rifle Disassembly, Part 1

Derrick sent me one of the rifles on my wish list, the IZh Baikal IJ 22.
The rifle wouldn’t shoot a pellet out the barrel. Although it’s an IJ 22, the rifle is .177 caliber.
Here is a Russian Airgun Forum thread on the rifle, with pics of the manual.

05221101
The rifle. Unique stock styling.

05221102
I love the stock detail at the wrist.

05221103
The other side.

05221104
The plastic medallion. Mine has the odd black streak on both sides.
”MADE IN USSR”! The rifle dates from the 1970’s and was produced for export, although I believe it was also sold internally.

05221106
The barrel has a release latch which I generally prefer to the spring loaded detent found on most modern spring piston air rifles.

05221107
The front sight has a great profile.

05221108
Let’s get started! The stock front screws.

05221109
With screw cups! That’s quality.

05221110
The front side stock screws.

05221111
I thought the rear screw on the trigger guard would be the rear action screw, but it’s just a wood screw. The front trigger guard screw was the action screw.

05221112
Butt plate and cap, with white spacers. Not sure what plastic they are made of.

05221113
The trigger block. Retained by a pin.

05221114
An anti-beartrap mechanism.

05221115
Cocking linkage.

05221116
More detail of the anti-beartrap (or perhaps trigger cutoff is a better description).



More to come…
