In the process of rebuilding your Crosman 130

Remove The Sight Screw First


When looking for a new piston, you will see new old stock pistons that have been around since the 1970s,

Crosman made two piston that will fit the Crosman 130,
 one with an O-ring and the other with a cup.  The piston to look for is the piston with the O-ring, all the new old stock versions of the cup piston should have been thrown out years ago.

Crosman no longer makes either of the two pistons  and the rubber on these old pistons are 44 years old, well over there shelf life.
 For the best results, find the old piston that uses an
O-ring for a seal and you will no longer be at the mercy of new old stock, the O-ring is replaceable for a measly few cents and replaceable by you.


Demand the Best


This is a new old stock Crosman 130 Piston that was self installed by a gun owner.
 He rebuilt the gun it worked  fine for a few weeks then stopped pumping, he sent the gun to me because he thought he did something wrong.

I checked the gun over and everything was in top shape, he did an excellent job on the rebuild, the only problem was the NEW OLD STOCK PISTON, the rubber on these old pistons are 40 years old and past there usefulness.

I installed a new O-ring Piston fixed the problem and sent the sweet old Crosman 130 back. 

 Be careful when buying new old stock Airgun parts,
if the part has rubber make sure its replaceable.


When the Crosman 130 was first introduced 1953 they were sold with a flat bottom aluminum piston and O-ring with a steel upper. late in production of the Crosman 130, late 1953 and into 1954 and when the Crosman 130 was in need of repair, Crosman issued the newer style 130 piston with a cup as seen in the image  above, the reason for the swap  is longevity of the repair. A Crosman 130 piston with a piston cup for a seal will out last a 130 piston with an O-ring if the owner forgets to oil or just never maintains the gun.  But it has been a known for more then 50 years that the O-ring piston out performs the cup piston buy at least 1/3 which is why Crosman Installed the O-ring piston in the Crosman 130 in the first place. I have run across many Crosman 130s with the Aluminum O-ringed piston that are still working today with nothing more then an O-ring swap, Crosman in there design of the 130 were on the mark for a nice air pistol that would be handed down thru generations with a simple O-ring replacement, when the change over to the cup piston occurred and the same guns became in need of repair they were put away never to be used again. because parts were not that common.


This $27.50 MINT gem came from a flea market and is a later production with the cup piston I will admit when walking around flea market and gun shows finding Airgun's in need of repair is one of my past times that I will drive hours or days just to seek out and find.

When installing the Airgunsmith Flat top Piston you must
grind an O-ring relief, this allows the O-ring to pass the pump arm slot
without cutting the O-ring. Don't get carried away, all were looking for is enough space
for the O-ring to pass the edge without getting cut.

Crosman 130

The Crosman 130 is a great little gun but will never be a big power house. The kits we are building will help increase
 the power on guns that use a piston cup, if you have the model with a flat piston there will be no power increases.

The intention with our kit is to bring back life  to these fine old guns not to make
them high power shooters but keep them as the great old shooter they have been for years.

The Crosman 130 is a fine old heirloom and if cared for will virtually last forever as long as itís cared for properly
and not abused. We are in the process of build kits including a brass O-ring piston and will be ready soon.

Having said that we have noticed a slight increase in power from the brass piston.


Crosman 130 Repair

When you send your Crosman in for rebuilding this is not the best way. Sometimes it make our work less and sometimes more.

Crosman 130 Rear Sight Screw

 If you do take your 130 apart just be careful to not break the rear sight hold down screw, Always remove the sight screw first. these are a tedious little bit to make.

If you have lost or broken your rear sight screw,
we have a screw with a screw cup, this is allows us to turn the screw without moving the rear sight from side to side.


The two highlighted are key to a solid rebuild
The check valve for the most part will last forever

As you can see the gun has a very simple design
the only drawback for self repair is the piston.
After we get rid of that and replace it with the brass piston
the gun will forever be a home shop rebuild.
I'll be the first to tell you, proprietary parts suck.

Crosman 130 hammer assembly

The inner exhaust valve seal goes here
you must be sure to replace this,

Below is the Crosman 130 Piston disassembled.
They can be rebuilt but the results are not as good as the
flat piston, also when its time for a rebuild the flat piston is a simple O-ring replacement not a custom made cup.


This is another 130 that has arrive for a rebuild
wonder where this gun has been hiding?

One day I will do a full rebuild process

and include the modifications needed to bring theses 130's
up to current standards.

Wonder how good this thing will look when its complete.

Below is a picture of both Crosman 130 Valves
The brass on top is the self cocking valve the aluminum
is a manual cocking valve. I like the bottom valve, its simple and a treat to rebuild.


Below is the reason I say use good oil and do oil all pivot points

Now; When I say oil your pivot pins, let this show the reason
why, oil on the pivot pins is very necessary if you want it to last.



Another one of Crosman's well designed components.
When rebuilding this Crosman 130 and the pump arm bushing is worn out its a simple 5 minuet machine job to get it back into top shape

This is another 130 Pump arm pin that the weld has failed.
These come in every so often, no amount of oil would prevent this from happening,
This is a production defect that lasted 50 years. We can see the pump arm
contact with the pin has very little wear and if the weld would have
 been complete we would of never had an issue.

I never like to weld the formed tin pump arm,
 a few of them just seem to burn away with even the lowest heat setting.

It looks like one side of the pin was never fused to the pump arm allowing it to rock back and forth
until the gap became great enough to allow enough movement to weaken the holding weld and finally
break free.  


Since the integrity of the pump arm looks to be at least 90% it should take the weld just fine.
The first thing to do is to machine a pin to a snug fit, making sure the width is the same as the arm.
next is to direct the weld and heat to the pin and allow the material to flow over to the
 pump arm fusing them together. 


With the Crosman 130 pump arm linkage pin machined and ready to go,
 it's time for two spot welds.

The Spot weld on the Crosman 130 Pump arm pin.
Looking through a 10 power lens, we can see good penetration and
we have covered more steel with the weld then the factory weld.


Looking like better then 50% penetration with a bit of cleaning and some bluing
this Crosman 130 is ready to put back together.
