Need big help with my NP XL and Super Streak

[Nomadic Pirate]

I really wanted to get this 2 guns to Ed for tunes, but the shipping makes it prohibitive, can't afford that kind of money just to send 2 guns back and forth.

And the fact that at the moment both guns are shooting perfectly, i just couldn't send them out.

Now, I guess I have to learn to work on them a bit, fist of all i want to buy a couple of seals so once the go bad I'm ready,.....where should I buy them ?...how hard is to change the seal ?

Next, ......can I put in the Gene kit without special tools ?

What kind, and where can I buy a good lube?.....I hear Moly alot.

i think those are plenty Questions for now,...I'll have more later 


Thanks in advance

Manny

Who were you going to ship thru and how much would it cost? Just ship the receiver, no need to ship the stock.

Manny, the SS and XL will both take this seal from JM.

You can also get moly (or actually a 3 lube kit) from JM. The 3 lube kit has everything you would need for several airguns.
http://www.airrifleheadquarters.com/catalog/item/251484/4169286.htm
If you decide to do it yourself, you will need several other tools and items. First, the SS will require a spring compressor to safely disassemble. The XL does not require the compressor due to the small amount of pre-load on the RAM. You can buy or build a spring compressor. We have instructions in our library section and on Charliedatuna.com site.
You will need some tools to debur, sand and hone the air chamber. Do a search for spring compressor and also search the Shop Talk and Airgun Mods gate for steps, hints and tips on doing a home tune/lube of the XL and SS. Be sure to look at my seal saving post in the shop section to help you get a clean install of a new seal in both of these guns.
Good luck and keep us posted.
Happy Shooting....and tuning!!!!

Manny first you need to buy or make a spanner wrench to losen the end cap, this is no easy task had to put mine in a vice between 2 towels also had to use the wife's hair dryer and still took everything i could muster to break it loose and i am 6"1' tall and 270 lbs at 44 years old but still  like to think I still got it...lol

hey LongIslandArcher  how much were the NP XL internals if you don't mind me asking.....ty

[Nomadic Pirate]

Thanks,

 so lets see if I understand, as long as I'm able to take the end cap off, I should be able to replace the seals without any special tool ?

about all the othe stuff, ( deburring and things) I think I need to do some search for pictures,...because I have no clue what you guys are talking about 

[Joshua A.]

here manny, this is very very helpful. with many pics as well. good luck! I am certain you will have a great time doing it. and I have also heard from a ton of ppl that those guns are very easy to work on because of having less pre-load than other rifles and therefore don't need a spring compressor. I really wish you the best and hope this helps you. also search "spring gun tuning" for many other helpful articles, i just found a bunch when i tried it...lol

The Super Streak doesn't require a spring compressor.  It has the same threaded end cap as the NP XL.  In fact, I have on order from Crosman, the internal parts for an NP XL that I'm going to be installing in another Super Streak.

LIA,
Then how do you propose he deal with getting that very strong spring out of his Super Streak, without a spring compresser, and without hurting himself ?

Paul

[ezman604]

Safety is a MAJOR issue at GTA Forums with giving out advice on airgun maintenance. You MOST DEFINATELY need a spring compressor to perform internal maintenance on a Super Streak!!!!
That massive spring is under a preload that can cause damage and injury if not controlled. The XL does not require a compressor to gain access to the RAM and internals.
DO NOT DISASSEMBLE A Super Streak WITHOUT A SPRING COMPRESSOR!!!!

IGNORE THIS FOLLOWING STATEMENT. IT IS VERY DANGEROUS AND UNSAFE.  "The Super Streak doesn't require a spring compressor.  It has the same threaded end cap as the NP XL.  In fact, I have on order from Crosman, the internal parts for an NP XL that I'm going to be installing in another Super Streak."

Aparently you do not practice safe air gun tuning LIA.  You know the GTA is all about safety with air guns no matter what application. This is an unsafe practice LIA and I for one do not want to see  this kind of unsafe practice posted on any of the GTA forums.
Gene

[ezman604]

And Manny, please do search the forums (the Shop section in particular) for Super Streak and XL home tune/lube/debur info. There have been a LOT of posts with helpful info. And even go back to the old GTA for a ton of good stuff. Best advice is to read a lot and understand the total process BEFORE diving into it. Have all of your tools borrowed or bought and handy before starting. Get your parts and lubes also. It will make the process SAFER, more enjoyable and the results more positive if you are fully prepared before diving in. Home tune/lube maintenance on airguns is very enjoyable for me. And I really feel proud when my efforts show in the whole operating cycle of the airgun. And I thrive on learning new things.
Good luck and keep us posted.

Manny, if you want to drive to Kailua, I will help you do a lube/tune on your Benji's. I've done quite a few and would be happy to help. You'd be amazed at how much better they shoot afterwards.

as much as I would like to dive in and do them myself, I'm not that mechanically inclined (good with wood but not with mechanics)......so Perry your offer is very, very much appreciated, if you don't mind we could make a date for the future , I go ahead and buy all the stuff and maybe when i see you doing it Than i'll feel better in the future doing it myself, ...brother Perry that would be awsome, thank you very much.


So what should I order ?

2 seals.
Moly.
Gene's KIT
New spring for the S.S.

Thanks a lot guys for all the imput, ....I really mean it

Paul and Gene and Dave,

I've done quite a few conversion of the Super Streak to a gas ram, one of which was for Dave (Ezman604).  It needs a spanner wrench to remove the end cap and I don't know how one would do that if there's a spring compressor blocking the two holes that the spanner wrench goes into on the end cap.  Yes, there's preload on the spring, but not quite as much as on other springers.  All I did was loosen the end cap enough with the spanner wrench till I could loosen the rest by hand.  I then put a double pillow case over the end cap and finished loosening it by hand.  When the end cap got free, the spring pushed everything into the pillow case and that was it.  Just make sure hold onto the pillow case around the receiver tube and point away from you when you take it off.

Jerry C.,

the internal parts for the NP XL came to about $70.  That included the piston seal (B22-04-1), piston sleeve (BT1500-02-100), piston (BT1500-00-2), plain plate (BT9M22-00-7), rear gas spring guide (BT1500-00-1), adjust washers (BT1500-00-4) and tube cover (B22-00-5).

[LongIslandArcher]

Correction, a spring compressor could be used once the cap is taken off.  You have to take the end cap off first and then put the compressor foot into the back of the rear spring guide.  Then you take off the screw that holds the rear spring guide and trigger assembly in place.  Then back out the compressor.

I took out the screw and the trigger assembly before I took off the end cap.  Once the end cap is loosened enough, a lot of the spring's preload is reduced and all the parts can be safely captured with a double pillow case.

[ezman604]

Yes, you got the parts for me to convert my SS. I opened mine up several times before and after that conversion. Very simple, you do not remove the stock capture bolt that holds the trigger assembly and the rear spring guide in place. You remove the end cap FIRST. Then secure the receiver into the spring compressor. Apply pressure to the trigger group and rear spring guide. Then remove the stock capture bolt and slowly back the compressor out releasing the preload on the massive spring.

[Perry]

Manny, after you get all the parts, leave me a PM and we'll set up a day to do the lube/tune on your Benji's.

[Nomadic Pirate]

Thanks brother, much appreciated

Perry,
I don't need help with my Benji, but I was just out side and the wind chill is well below zero, and we're expecting a foot of snow tonight !!! I put extra air in the tires ...is that invitation to "drive to Kailua" still open ?

[Perry]

Paul, it was 85 degrees and sunny yesterday. Here is a picture I took Christmas morning from my bedroom balcony:



You can drive over too. In addition to some moly, can bring some sun block as well?
