Crosman 101 Back in Operation
« on: February 12, 2019, 08:42:12 AM »
My first attempt at freeing the valve on this 101 failed. It held air for a short period of time but not overnight. I thought for sure it would have to be rebuilt because the discharge from the first attempt began like all the previous flushes, dark residue to clear. I guess you could say I was board so decided to give the flush another go.
 
This time I cycled the gun to 4 pumps & with the lever arm partially open dumped as much alcohol into the air tube as it would hold & dropped the lever closed. I let it sit in that position (muzzle up) for one hour. Slowly cycled the gun another 4 pumps over a 5 gal bucket to catch the alcohol as it ran out of the tube & there it was, more 71 year old crud coming out of the muzzle. Every one of those marks on the rag accounts for 8 pumps. Every time the discharged appeared to be clearing up I added 10 drops of pneumatic gun oil, cycled the gun & dumped air a few more times, added more alcohol into the tube until there was no question all the crud was gone. Competed the flush by adding another 10 drops of pneumatic gun oil, cycled & dumped air until the oil discharge was gone & swiped clean the inside of the barrel. The final test was to see if the gun would hold onto all its air overnight. Knock on wood...he did.

There was no question half way through this second attempt at the flush that progress was being made. Previously the gun built up good pressure to 5 pumps with no change in subsequent pumps. This time every additional pump made huge gains. I will test him on the chrony latter today to see where heís at.

Nice work!

I'll keep that method in mind.

That's a nice looking 101! It's good to know the alcohol flush treatment is getting good results from those that try it. What have you got to lose? It won't damage anything and worst case you'll end up replacing the seals anyway. When I first suggested squirting alcohol down into the valve to flush it people thought I was drinking more alcohol than went into the gun.  ;)  I like your technique of alcohol then oil and repeating the cycle to get out crud that been in there a long time.

Thanks guys. I've come real close to letting this step child of sorts go. He's taken a back seat to just about every gun I own but that timeless vintage look keeps him locked into the collection.

I should have some numbers for him in a few hours which should tell the tale. If he turns out as good as I think he will it will reinforce my belief concerning how good this alcohol flush is. It has worked on every one of my guns but one. As it turns out I probably gave up on it earlier than I should have.

Is there a serial number on the pump strut? Looks like a twin to mine.

I tried your method once, putting one to two tablespoons worth of alcohol down the pump tube through the air hole (I used a syringe).  I went to close the pump arm and it wouldn't go down very far.  When it hit that liquid it stopped going down like there was a chunk of steel in there.  I'd say I got the pump arm about 5/8 closed before it hit that wall.

I had to open the pump arm all the way and turn the gun muzzle down to drain the alcohol out.  Did I do something wrong?

It sounds like the valve is stuck shut.  Hydro-lock is like that.  I bent a con-rod in an Audi engine bump starting it with a cylinder full of gas that way.  I'd bump the pump arm gently and see if that breaks it loose.

Luck,

The valve IS stuck shut Randy. That's why you leave the alcohol in the gun overnight to let it work its magic. Make it easier on yourself & pour the alcohol in here...

It's not going to work on every old gun. I just fixed a Benji 310 that had a frozen exhaust valve. Tapping the exhaust valve shaft with a hammer didn't budge it. No amount of alcohol was going to unfreeze it. It was one of those cases that pulling out the valve was the best solution. I was still able to save the original seals and lead gaskets. It logged 710 fps after it was back together.

Thanks Steve. Looks like I'm in the ball park.

BTW; what is the serial # of your 101? Is there a way to pin point the year? Crosmans DOM seemed vague...

My glossy 1949 is 1433 J   
My Kringle has no serial number

Nothing is certain with Crosman.  Iím assuming my Kringle paint is the last made?  Diablo Knocking knob was their last improvement?  On it they also eliminated the spring cover on the pivot pin.

Marty, does your rifle have a steel or brass barrel.  Does it have the screw on clip bolt retainer?  Thanks.

Do you have a through air bolt or a solid probe.  The through air were the last ones, with your serial number I bet itís though air?
