Crosman Model 99 Rifle Disassembly, Part 3

On I go…

Two more screws on the left receiver half.

Removed.

The barrel comes free.

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

The pellet cam rod, shuttle, etc.

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

Valve assembly.

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

It slides out of the valve assembly.

Piercing pin nut.

Removed, the mesh filter comes out as well.

Piercing pin parts.

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.

Valve stem housing.

Unscrews…

Valve assembly.

Exploded.

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

Seal inside the nut.

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.
