    Hello All,

    I purchased an Air Venturi Compressor from Air Gun Depot back in November of 2017.  The only issue I've had with it was about a month ago.  Had some buildup on the valve plates that didn't allow it to make pressure, I was able to clean them and restored normal function.  Aside from that, it has performed flawlessly and I have been extremely pleased with its performance….until today.

    The armature/drive shaft snapped!!!  I was filling my tank and at about 4000 psi the motor started free wheeling….no grinding, no noise, nothing!!!  As you can see, it's a clean break at the bearing.

    I realize the warranty is only one year.  But, for what this unit costs and only two years of use, this type of failure in my opinion is unacceptable.  I am hoping Air Gun Depot will stand behind their products.

    As big as that shaft is, it should not have failed!

    Why do you feel like airgun depot should stand behind their products after it's warranty? All items in the states is only for 1 year unless stated in the manual. If it was under warranty then yes they should repair it at no cost..but since you bought it in 2017 and now it's 2019. They do not have to stand behind their products. You can either send in back for repair and paying the fees. Or just order the parts and fix it yourself. I would order the parts and fix myself cause you can learn a lot about your own compressor and how it works and how to repair it. Sending that heavy compressor back in gonna cost a lot in shipping to them as back plus labor fees and parts.

    Same thing happened on my Honda 50cc ,anyhow it is not how big a shaft it is it is the strength of the rod and that rod ,shaft looks to be porous.

    I'm not expecting a "free" replacement.  I am hoping they will work with me to get it repaired at a reasonable cost or perhaps a new compressor at a discounted price.  As I stated, I know it's out of warranty…..this type of failure for a solid steel 1" shaft that drives two small pistons/cylinders is ridiculous weather it happened in two years or ten years.

    Usually when I see a shaft broken off like that it is caused by a “dropped valve” or other part impacting the piston and/or rod. Have you pulled the heads and checked the internals?

    Sorry for your problems, I can relate. Mine failed about 2 months ago in about the same place on the crank. Here's my post https://www.airgunnation.com/topic/my-av-compressor-had-a-major-fail/. Although it sucks big time, fortunately AV had that armature in stock. I ordered one and replaced it myself. Not an easy task but I got it done. The biggest issue is getting the armature out of the motor housing. I had to snip a few wires after carefully making notes and pictures.

    This is the last part that I would expect to fail. May be some tiny cracks has developed in the forming process of the rod. If I were AV , I will give you the parts for free in exchange for deletion of the post

    Is that black mail? The part is only $99 on prymaid air. And PA always have discount codes and free shipping. Asking for a freebie when it's out of warranty. Then AV would have to send everyone who owns their compressor free parts for the life of the compressor.  They are a company.  They need to make money to feed their family too you know. If you were a company, I'm pretty sure you wouldnt send free parts for a out of warranty product. Then you would have to do it to everyone.

    Thats a shame, the only compressor that holds up over any time is Bauer and they are a fortune.  yong heng atleast isn't so expensive to replace.

    Air Venturi has helped me out a little (high pressure seals and couple of other small items) since my compressor has had so much trouble. I keep in close contact with them when I have issues which I think helps. They didn't offer and I didn't ask them to send me a new armature knowing the compressor was almost three years old. I was just tickled finding out they actually had one. So for right at $100 I got it back up and running.

    Jimmy-

    Thanks for the links to the parts, greatly appreciated!!  I was very surprised to find out that I am not alone in this failure of the shaft.  All the more reason in my mind, for Air Venturi to step up to the plate and take care of the customers who have had the shaft completely break in half.  I took it all apart and there is no damage to anything else…meaning nothing came loose that would have caused a lock up or seizure while the motor was turning.  Sadly, this will probably happen again after the repairs are done. Reason being the counterweight is not supported through to the other side of the case….it is only mounted to the one end of the shaft.  Not having the drive/crank shaft supported on both sides of the counterweight allows more vibration to take place and with the crappy chinese steel used for the shaft, it's only a matter of time for it to fail again.  If this was a $300.00 Yong Heng from Ebay and I got two years out of it, it wouldn't be such a big deal.  But, the Air Venturi cost me $1300.00…Here's a quote from the owners manual:

    "Your Air Venturi Compressor is manufactured to the highest possible standards, using quality materials to give a lifetime of service…"  Well a failure such as this after only two years is hardly a "lifetime". 

    I put a call into Air Gun Depot yesterday and left a message..haven't had a call back yet.  I also called Air Venturi a few times and never got through to anyone, didn't leave them a message.

    Rick,

    When mine broke and I was discussing (emailing) the problem back and forth with Jordan at AV I asked if this particular problem had happened before and he said it had. He didn't say if was just once, twice or how many times though and I figured since mine was out of warranty and it was almost three years old I wouldn't push the issue. You may be right on the design plus throw in the quality of the material being used as the reason for the failure. Now that you know there is an issue with two breaking just recently you might push back and see if they will work with you. Jordan is just a tech so he may not have the say so on issues like this so you might have to go a little higher. He has however been a lot of help to me doing what he can. You might try this email address to make contact with Jordan. Jordan G (Air Venturi) <[email protected]>.

    One positive thing though…. if there could be one is that your learning a lot about the compressor as I did and can make the repairs yourself and hopefully not have to send the unit back to AV.

    Good luck

    Jimmy

    Morning Jimmy,

    Thank you for the Email address, I will definitely contact Jordan.  It really sucks….I checked PA and the armature isn't due in until sometime in February.  Hoping AV will have one.

    As far as learning about the compressor, I have a background in heavy equipment/machinery repair and maintenance.  So, doing any repairs on this little thing is a piece of cake…I just need the dang parts!!!  Thank you again for the links, your back story, and the contact info!!

    Regards,

    Rick
