viair problems

so ive got a viair 450 that doesnt seem to want to work. when powers applied to it it just clicks but wont run. any suggestions? also are there rebuild kits for it?

there's a rod & piston kit, head kit & cylinder wall kit.

I don't have them listed on the site but let me know if your interested.

Lmao..

I've used the piston/cylinder wall rebuilds when they run, just not running like they should.. for it clicking, it could even be the brushes or thermal switch (I'm pretty sure) and Viair could probably get those type of replacement parts if you call them up. Hope ya get it working..

im tellin u bro everyone laughs but since the compressors only have so much lube in them they seez up all the time..... I use to always spray lub in mine and beat it with a rachet and shed start goin again. U can tell if you turn the compressor on and the body gets warm. that means it is still tryin to push the motor but it cant cuz its stuck. So tap it with a hard object and see if she starts movin again. Wouldnt suggest leavin in like that but if ur tryin to get back and forth for the time bein and u cant afoord a new compressor u definatly cant beat that. Rebuild kits are like 70 bucks for a viair. cheaper then buyin a new one. Good luck

ive never had a problem with a viair seizing up, or having any trouble, but i always install the recommened viair pressure switch/relay, and try to advise the owner that you need to run it by the manufacterers recommendations....

You should never lubricate a VIAIR pump, ever! Despite what you may think, there's nothing inside that will benefit from lubrication. The bearings are sealed, the cylinder wall is an anodized aluminum and the piston seal is PTFE. There's nothing you can add to a VIAIR compressor that will make the piston slide easier within the cylinder or make the armature turn better.

There are repair parts available however for the pumps. Please see below, several typical maladies and the cures for them...

If you are going to replace a piston or piston seal, you should double check the cylinder wall as well since a scratch in the cylinder wall can damage an otherwise perfectly good piston seal by allowing it to rub back and forth over a damaged surface which will in turn damage the piston seal.

If you have problems with a compressor that's not starting and have to use something to tap on the compressor - inspect the carbon brush assembly (they can be replaced.)

If the compressor is not building pressure and is blowing air out of the intake port, you might need a new piston seal, a new check valve or new flapper (reed) valve.

All of these parts are available. About the only things you can't replace with repair parts on VIAIR compressors is the housing, and the armature. Everything else you could possibly need is available.

Hope this helps...

i got 2 380s in my garage that need rebuilding where are these kits?

I have the 380 Piston, Head, and Cylinder Wall/Gasket kits available.. PM me if you haven't already found some.. I'd be glad to help out.

Always buy from an authorized distributor whenever possible! If you have no luck finding what you need, please feel free to contact VIAIR directly. We do sell the repair parts to Jobbers/Distributors but no one stocks every single part for every compressor.
