Crosman Model 99 Rifle Disassembly, Part 3

On I go…

10301001

Two more screws on the left receiver half.

10301002

Removed.

10301003

The barrel comes free.

10301004

I assume this nut is to adjust the gap between the pellet shuttle and the barrel.

10301005

The pellet cam rod, shuttle, etc.

10301006

The shuttle does not have a setscrew to lock it on the rod the way the model 600 does.

10301007

Valve assembly.

10301008

Spring on the end of the valve stem extension/transfer rod.

10301009

It slides out of the valve assembly.

10301010

Piercing pin nut.

10301011

Removed, the mesh filter comes out as well.

10301012

Piercing pin parts.

10301013

The seal is a metal ring with a rubber center. Odd. In theory I should be able to use the piercing pin and seal used on the Model 38 pistol, I hope.

10301014

Valve stem housing.

10301015

Unscrews…

10301016

Valve assembly.

10301017

Exploded.

10301018

The valve seems to be the same as on the Model 38 revolver.

10301019

Seal inside the nut.

10301020

This plastic piece is loose, but retained by a staked steel washer. I’m going to keep it in place, unless forced by circumstances to replace it.

Now to clean and get together some replacement parts & seals.
