XS-B18 I'm no expert and I'm a bit puzzled....

[Blue]

I'm just spitballing early in the morning here but you might have luck finding replacement parts (the broken roller bit) from Crosman.

Since they use the B-18 as a base for some (a lot?) of their rifles you might be able to order it from them.  Look through their diagrams and parts lists, or maybe post the question specifically in the Crosman Gate asking for the specific part number.

I have heard that as long as you know the part number, ordering from Crosman is easy and inexpensive.

p.s.  Has the new spring been set yet?  If it hasn't been compresses before, it may seem longer than it will end up once it gets cycled a few times.  I remember seeing replacement springs at one time that you could have pre-set so (I think) installation was easier.  I haven't been down the replacement spring rabbit hole yet so please excuse me if I am mistaken.

I never thought about checking out the Crosman part # for a possible replacement roller, I'll have to look at it a bit closer but it seems that mine was installed over the axle pin and then the end of it was flared out to prevent it from sliding off, not sure how I would get a new roller over that pin without removing the flare with dremel tool and then keeping the new roller from coming oof the pin while in use, I'll check it out a bit closer and then when I have a chance I'll take a couple pix of the broken roller and the pin it rolls on and I'll post them.

I know the Crosman Quest looks almost Identical to the XS-B18 and probably basically is so maybe it uses the same roller, I'll do a bit of digging and see what I come up with on that, Thanks for the idea and the Crosman part..... that gave me a big DUH........! moment. LOL!

Never heard of setting the spring as you mentioned but then again for me to not hear of many things related to the springer air guns is not unusual since repair to them and mods are fairly new to me on the springer guns, I have dabbled with them and had several of them apart over the years to replace leather seals in some of the old chinese models and I have replaced a few springs in them, but I never got into the mods other than some shims and and just polishing the internals for smoother operation, but I can see how what you say could be the case to an extent, because once the spring is under full tension a few times it is bound to settle in a bit from where it is when never being compressed before, the preload on the Tarantula spring I have will be pretty high to begin with no doubt but I'm sure it will settle in and be very strong in my rifle based on the fact that it is 0.010 larger wire size than the original and I can tell by just handling the two that it is a much stronger spring, very rigid and stiff, the old spring can be compressed some just in my hand and its a bit floppy feeling compared to the Tarantula Spring.

Thanks Again Blue

Did some looking and it seems that I was right about the roller being a permanent item on the cocking lever, so I will call Crosman and try to order a new lever from Crosman, I found the part # B18-07-00 it is the same part on the Quest 800, Quest 1000, & Storm 1000 and I'm sure a few others also, so if it isn't to high I will just order a new arm and be done with it.

Just wanted to post an update and say that I finally had time time get the XS- B18 rebuilt today, Tarrantula spring and seal installed along with everything deburred and well polished, chamber honed heavy tar on spring and the good moly lube on seal and a good thin coating on piston, haven't done and work on the trigger yet but it is stronger and smoother firing than it has ever been, cant wait to put a couple hundred rounds through it and then see what the accuracy is gonna be like.

I think im gonna be really happy with this rifle when its all said and done.

I know this is an old thread and hasn't had a post in several months, but I have not been on here in a while either so since I seen this request for an update I wanted to give it.

Short and sweet update is that the XB-18 is an excellent shooter now, super accurate and hit like a freight train, I am very impressed with how this little rifle performs after installing the Tarantula Spring and new seal, the tar on the spring made this rifle so quiet and smooth, very happy with the results.

Peace, Shan
