Benjamin trail XL barrel replace

I think the allen just removes the end cap of the shroud.Then the shroud turns off.

I heated the shroud and it came right off.  👍👍

The oval end goes through the similar shaped opening in the cocking slot and rests in the cutout in the piston. Insert it before the pivot screw.

Is it supposed to look like this?

Yes, just lined up better.
There are several way to remove the chisel. It MUST be pushed in. Then the pivot bushing has to be pushed out. 5/16" or 8mm. I cushion my vise jaws. I clamp at the yellow arrows while pushing the chisel(red arrow)in with the side of the vise. Clamp snug, push in, then tighten. Drive out the bushing. Then the reverse to install in the new block. Make sure the bushing is flush with the sides of the breech block and not protruding.

So how do I line it up to insert the cocking arm?

Stick a screwdriver in there and twist it until you can line it up.

sounds like Matt has done this once or twice, not much to add.. When driving those pins  out , using an old drill press as an arbor press really helps , u can drive it with good leverage from the press and a steel dowel in the chuck,. ( for future reference

Thanks guys for all your help.  I was able to successfully to swap from a .177 to a glorious .22.   Btw, what would you guys recommend for it? I shoot crosman premier hollow point pellets.
👍👍
I’ve heard people say you gotta clean a new barrel, should I?

I would clean any grease or oil out of it.Try some pellets with more heft.Skenco,JSB and H&N are good ones to try.Mine shoots these well just not to the same point of impact.
