I replaced the trigger valve on my Harbor Freight, Hitachi style, Pierce framing nailer, you can too

My Harbor Freight, Pierce-branded pneumatic framing nailer sprung a leak in the trigger valve. I couldn't find any instructions or videos on how to replace it so I decided to make one with no experience or expertise. If this video helps you diagnose or repair your own nail gun please leave a comment & give the video a thumb.

Very nice job, explained it thoroughly, not to mention the BIG PLUS he did it all in ENGLISH!

sir you’re a life saver !

Appreciate the video in changing mines today very informative

[@orinmed1-ex2hc]

Your video was very helpful I was able to have the old out and new part in, in about 20 minutes. Would have taken longer had I not watched this. Works great again. For reference the Hitachi NR83A is the same as the pierce. Amazon has multiple parts for this particular framing nailer. They sell the plunger and trigger vale in one kit.

I just purchased the same nailer brand new in the box for $80. I think it was at that price due to a model change. I plan on buying the same part ust in case I have the same issue. I'm gonna save your video. Thanks

For those that are in the middle of a project and all you need is the BB. A 6mm Airsoft BB will work in its place while you wait for a trigger kit. If you happen to have one lying around.

You rock thank you I wish you the best

Thanks for the video! Will be doing this shortly.
FYI, they sell an actual siding gun which fits the smaller nails

Also, hold the trigger down and push on the “foot” to shoot a nail, don’t press it down and then pull the trigger, makes it much easier, just bounce it!

Thanks for the info, my nailer just suffered the same fate, now I can fix it with your guide, can complete my new home for the family in CO... Thanks again for the very helpful video.

Buen trabajo 👍

It's almost like the plastic BB and maybe the plastic valve should be made out of something much stronger but, I guess it wouldn't be a Harbor Freight budget version. Good video though.

Thank you, the replacement part looks like it is made of a different material. I think that there is a good chance that Harbor Freight sold me a Hitachi replacement part.

[@darthslipknot91]

@Fire&Rod Most likely. The Hitachi/Metabo and Pierce look like they definitely come out of the same factory. Wouldn't surprise me

[@MrChristian3777]

Thank you for the info and What's the part number?

[@firerod3074]

16083 was what I ordered, but the call to the Harbor Freight number was unexpectedly personal & helpful. They can probably find it based on your model number or even description.

What’s the part number?

[@klatubaradanikto]

16083 good luck!
