Need Help from HW80/R1 Experts

[HWNut]

Hey there,

today I received a new spring for my old HW80 and to my surprise, the spring is much bigger in diameter than the HW95 spring. I also noticed that the white plastic spring guide rod is as big as the one in my HW95 so the white spring guide wobbles in the new bigger HW80 spring. Is this right?

Pic for comparison:

On the left HW80 spring on the right HW95. All springs are original Weihrauch.

Sorry double post.

well for one the R1 and HW95 are 2 different tube sizes and are not really ment to interchange! the R1/HW80 is a 30mm tube and the R9/HW95 is a 26mm tube, the OD and ID of the springs as well as wire size are complete different!  

[HWNut]

Okay, now that I know the OD and ID is different, what's with the white guide rod for the spring? Is this the same diameter for both rifles the HW80 and HW95? Only the metal ring of the guide rod is bigger on the HW80. Is this correct?

[Mark 611]

no the OD is bigger on the HW80 guide, the wire size on the HW80 spring from the factory is .148dia and the HW95 factory wire size is .122dia

Weihrauch in my opinion has really messed up changing their old steel spring guides to the  newer cheaper and more brittle pieces of junk spring guides they use now in their HW 80 and now the 95 as well. I imagine all the models have been changed over?!?!?!  Mine snapped in two after only a tin and a half worth of lead. I would keep the spring as a back up reserve and just go ahead and order the JM R1/HW80 kit.
Just a guess here, but because of the wire size and length of the HW80 spring, they (Weihrauch)might not feel the guide has to be as tight in that spring, as with the longer and thinner wired 95 spring that would have the tendancy to buzz more. Like I said, just a spectulation on my part.

For me it seems there is only one guide rod size for the HW77, 97, 85, 95, 35 and 80 because I can't find a thicker guide rod for the 80.

[Mark 611]

The 77,97 85,95 are all the same set up as far as guides and wire size even the HW50s has the same size guide with a shorter spring! I don't know about the 35 and the 80 being the same if you want to tighten up the guide to fit the 80 spring you can use some heat shrink on the guide to give it a better tighter fit I would suggest you just buy a new factory guide their not that expensive and you can buy one from Specialty Shooting Sports

lol I'm sooo stupid. The bigger metal ring for the HW80 guide has the same hole diameter for the guide rod than the Hw95 one. So there is only one size fits all... for now I will stick with "all stock" configuration.

Thanks for the advice Mark. Maybe I will buy the tuning kit.

[Mark 611]

Tom is right buy a JM kit for it!

[HWNut]

Well, if anyone disassembles his R1, please let me know what was inside your gun.

The most interesting part would be the rear spring guide diameter. I can't believe they put a much smaller guide in it...

The JM kit's are the way to go and what I install on customers tunes. Ed

well inside my gun are all the correct parts for a current production HW80/R1 well use to be anyway but I do have some factory parts lying around! looks like the guide in this one I have is .588dia and it a plastic guide I also have a steel one!

[HWNut]

This sounds about right. My nylon rod is only 5.2dia.
