Over the weekend I let a friend of mine shoot my 48. Well he over cocked it and broke the little rod that is threaded on each end. I had a spare new rod so I put it back on the rifle. The problem is that when I cock the rifle now the arm does not lock back to the side of the rifle as it did before. My question is, what is the proper way to adjust this arm?
Thanks in advance.

well what I would do is if you have the old broken parts count the threads that were in the hole off the rod { where it gos into the compression tube} and screw your new rod in then go to the back adjustment and eyeball it get it close put your pin in and pull the cocking arm in and out and make the adjustments only at the end where the cocking arm pins into the reciver you my have to make a few adjustments this way untill you get the proper closing pressure on the arm. it should close firmly but not to tight but you don't want any rattle in it either.
-
Well I took the old rod and broken parts out and threw them away. Didn't even think about counting the threads (duh).I figured it was a simple adjustment. I'll play with it some more this afternoon when I get home.
-
well its not a total loss here, you'll have to make an educated guess and you'll just have to make the adjustments at both ends, it's no big deal just a PITA LOL, but start at the front, you can line it up close before you install the pin in the reciver, if you need my help just ask!
-
I believe the correct adjustment is 2 1/4 inches from the stock before it locks in. Hope this helps. Dustin

very good info!
-
slightly OT, in a pinch as a temp measure you can use a section of 5mm thread rod for that link, it does take Umarex a while to ship such parts.
I was fortunate enough to get a spare rod from yamaharider with the gun when I bought it. Thanks for the tip though just in case this ever comes up again.

Thanks for all the help guys. I installed the new rod yesterday. Piece of cake from the great advice here. Now all is well with the 48 again. I love this place.
-
cool! I luv it when a plan comes together.
-
Now if someone could tell me how to take about 3 or 4 pounds off this gun it would be the perfect hunting ag.
lol

get your saw out LOL!

If you weren't using the sights and planed on keeping the gun you could remove the sights take about 3'' off the barrel and cut the barrel sleeve back and add a delrin muzzle break and would lose about 1/2 to 3/4 of a LB doesn't sound like much but it does make a big difference.

My 48 didn't have a cocking lever or rod when I bought it. It was perfect in every other way. Except for being so heavy.
I had to do the trial and error method of adjusting mine. I've thought about shortening the barrel to about 12-13 inches and routing out the inside bottom of the forend, and the inside of the buttstock. I just don't think all that extra weight is necessary. But, I've been wrong before.
I do think that if it was the length and weight of an R9 with a chopped barrel, I'd shoot it more. I'd probably take it hunting a bunch, too.
Then again, the weight could help dampen vibration when shooting. Plus, it helps strengthen your arms for cocking that sidelever.
Maybe I should chop and lighten my 30 first. If it shoot well, then I can put the 48 on Weight Watchers. I like the 48 way too much to not shoot it. It's a great, accurate, hard hitting AG.
Great info on that page. I saved it for future reference when I tune my 48.
I especially like that brass brake. It looks like a couple of razor handles I've made.

Forget losing weight on the rifle end of things. Pump up and there will be no problem to tote the rifle around. lol
