rebuilding Viair compressor

how to rebuild a Viair compressor

[@sthomson06]

Thank you for this video, helped a lot. I have a vair compressor I need to take apart this week and it looks straightforward.

[@Slicpartna]

Thanks for watching Let me if you have any questions

[@resdawgs]

Very helpful. Mine just went out yesterday. But i already ordered 2 because i got it for a good price. I am definitely going to rebuild the bad one using your video. Thanks.

[@Slicpartna]

Cool, Let me know if you have any questions

[@victorrodriguez9882]

Thanks for the video. It was very helpful, you saved me from buying a new one. Only spent $38 on a rebuilt kit. Much appreciated.

[@davidgarcia3610]

Can you share the link where you bought the rebuild kit please thank you

[@JeffRigney]

Where did you get the rebuild kit?

Thanks for the video. I just ordered two rebuild kits for my 380c’s powering a 20 gallon air tank to my Nathan K5LA train horns.

[@Slicpartna]

Awesome, I hope everything work out for you Let me know if you have any questions

[@WVChad]

@@Slicpartna will do. Thank you

[@songofthepassaic1521]

Awesome video, thanks for sharing it. I also appreciate the fact that you posted an honest everymans video, not a fake one where everything is awesome and perfect works perfectly the first time👍

[@Slicpartna]

I appreciate the compliment Thanks for watching

[@joekirklin]

Great video. Not only did you show us how to rebuild it, you showed us that it’s not a bunch of plastic junk inside like so many other compressors. Thinking about building one of these into my off-road project for airing up and down tires. Some guys use them (with a tank) for locking differentials.

[@Slicpartna]

Wise decision, there isnt anything worse than being on the trail and need air to air up a tire. It better to have it and not need it than to need ir and not have it

[@PersonaN007Grata]

Someone as handy as you are should have a proper work bench. Good video. Thx.

[@gobbledgoop8350]

thank you for the knowledge!!!

[@Slicpartna]

No problem Let me know if you have any questions

[@mase7207]

Thanx for sharing great vid!

Thanks for the compliment Let me know if you have any questions

[@billyhernandez7540]

Great work sir mine is making a noise too and barely putting air

[@Slicpartna]

Sound like it needs to be rebuilt Let me know if you have any questions Thanks for watching

[@billyhernandez7540]

Did noise went away sir put new rebuilt kit on ur compressor

[@Slicpartna]

@@billyhernandez7540 if your compressor isn't producing air pressure it will need to be rebuilt or replaced. I would suggest taking the compressor apart and evaluate the condition. Let me know if you have any other questions

[@harleyd9857]

Some how the positive lead /wire on my VIAR 380c has become grounded. Thank goodness it didn’t short out my battery.

[@Slicpartna]

Wow That could have been bad Good thing you caught it

[@daveschidlmeier6425]

When you install the connecting rod, is there a stop so you don't put it on to far or little. Remember that's determined where the piston rides in the cylinder. Just saying. What kind of oil did you lube the cylinder with... silicone oil?

[@isleeparoundoverland7583]

Yes there's a stop

[@stickbogart3657]

❤❤ 🔥🔥🔥🔥🔥🔥. good job I have 6 of those air compressors 4 of them are in the toolbox of my pick up truck just for my airhorns. I will be buying those kids to rebuild the 4 air compressors that I use for my air horns I’ve noticed that they’ve gotten kind of slow on the air pressure buildup. I’ve had the pressure gauge all the way up to 250 psi to test for leaks, but I run the system all the way up to 170 psi but I do have a Boost button that will run it up as high as I want it as long as I hold the button in. After blowing my airhorns, I wanted rapid recovery on the air pressure so I have two switches, one activate. 2 air compressors, and the second switch. Activates. 2 more air compressors. Trust me the airhorns wake up the dead if they are not staying in their own lane, going down the freeway because they are texting on the phone. I don’t want circus clowns to hit my truck so I have the wake up call button that I can push on my dash and wake them up. ❤❤❤❤

[@Slicpartna]

Cool beans Let me know if you have any questions

[@stickbogart3657]

Trust me, you would love to see it. It’s completely custom built

[@Slicpartna]

@@stickbogart3657 I love custom

[@swatz22]

So my compressor isn't kicking on at all. Air tank is practically empty and compressor isn't doing nothing. Any ideas where I can start to diagnose the issue?

[@sweetmemories4448]

Thanks for the video. What lubricant did you use?

[@Slicpartna]

If I remember correctly, I used some regular engine oil just to lightly lube the cylinder

[@zackvw3164]

anyone know what size allen wrench it is?

[@williamward3433]

Where do you get parts for the viair ocmp.

[@Slicpartna]

You can find replacement parts for viair compressors on hornblasters.com Let me know if you have any other questions

[@kalimullakhannazeerkhan2486]

Hi, Great video .Can you suggest me the thermostat specification and purchase details?

[@Slicpartna]

Thermostat? Are you talking about the pressure switch?

[@jmsssx]

Thanks sir

[@jesusmartinez-dy1ue]

👍👍👍👍👍👍👍

[@dptp9lf]

Great Video! Can i ask where you got the rebuild kit?

[@Slicpartna]

Thanks for watching I got the rebuild kit through www.newmaticsinc.com/ Let me know if you have any questions

[@resdawgs]

How would we know if thats the only part on the compressor that fails? I ask because when i look at part kits there are different types at different prices.

[@Slicpartna]

Use the model number for your compressor to order a new piston and cylinder Take your compressor apart first to see if you really need a cylinder. look for signs of scoring or scratches on the cylinder wall Let me know if you have any other questions

[@daveschidlmeier6425]

Do you think it would be wise to put Blue Lock Tight on the bolt threads. So it don't come apart from the vibrations that these units are known for. As you stated these are made of Aluminum and can't handle high torque on the bolts...Just a thought...time will tell.

[@Slicpartna]

Blue lock tite would work fine Let me know if you have any other questions

[@thegrave2000]

it's a must. originally it was used for this bolt, that's why it goes off so difficult.

[@romelpatani884]

Hey brother! So quick question on the head, last night I snapped both of my heads due to overtorqueing the fitting on it.. whats your recommendation? Hand tighten & 1 rotation? Thank you!

[@Slicpartna]

I would only go 1/4 to 1/2 turn passed hand tight. There is a gasket that will do the sealing. Anything more than that, you can strip the bolts or break something

[@romelpatani884]

@@Slicpartna perfect! I do not plan to strip the head again, just wanted to double take before doing the process again. I appreciate your help brother!

[@Slicpartna]

@@romelpatani884 no problem, feel free to reach out if you have any more questions

Is there a way where you can get to the wires that come from the side ?

Im sure you can, just have to take the cover off Let me know if you have any other questions

Молодца, чернявый. Перчатки мог бы и не одевать. Руки в них потеют.

[@rustylocke]

Well did it work? I'm at the point to decide to rebuild or buy new.

[@Slicpartna]

Yes it did work, I would suggest replacing the compressor if the motor sounds weak or under strain during operation

[@rustylocke]

@@Slicpartna so you would suggest total replacement? I took mine apart and it is a bad bearing making a bunch of racket. I think it still pumps air.

[@Slicpartna]

rustylocke if the bearing is making a noise it will eventually sieze up

[@rustylocke]

@@Slicpartna I'm going to replace the bearing and put it back together and see what happens.

[@Slicpartna]

@@rustylocke cool, be sure to oil the cylinder before putting it back together. I hope it works out for you

[@resdawgs]

Out of curiosity what do you use your compressor for?

[@Slicpartna]

I have an air suspension on my suburban

[@resdawgs]

@@Slicpartna cool i have air suspension on my 2006 Altima 3.5

[@resdawgs]

Mine doesnt turn on anymore. I swapped fuse but it still stays off. If cylinder is no good does it still try to operate?

[@Slicpartna]

Ok ok Might be the motor itself Hook the compressor directly to a 12volt source That will ley let you know That bypasses relays, fuses and pressure switch

[@resdawgs]

So ill do that once i get the new one. Take out old and test it. But yeah complete rebuild kit with power supply is about 150$ which is still worth repairing and not buying a new.

[@resdawgs]

Also before the old compressor stopped working i heard it making some wierd sounds as the other one was working.

[@stevep6108]

nice vid thanks for sharen please go buy yourself or make yourself a table to work from - your killing your back , work easier man nice vid keep it up

[@Slicpartna]

Thanks for the compliment, Yes you are right about the table. I was talking to a friend about the same thing yesterday Thanks again

[@aakaashmaraj901]

My compressor is making a lot of noise would this solve the problem

[@aakaashmaraj901]

It wasn't making noise before just started to make noise and the tank taking a lot longer to full.

[@resdawgs]

What type of oil did you use?

[@Slicpartna]

I just rebuilt another one, I didnt use any oil on this one Just wiped the cylinder head clean with a lint free paper towel and brake parts cleaner. Be careful when sliding the piston into the head. Let me know if you have any other questions

[@resdawgs]

@@Slicpartna i was thinking maybe a little compressor oil?

[@2vgod460]

Way better videos

[@aasastephenson1538]

How old was the compressor before you had to rebuild it?

[@Slicpartna]

The compressor was about maybe 3-4 years old Let me know if you have any other questions

[@aasastephenson1538]

@@Slicpartna thank bro! And how often did you replace the filter?

[@Slicpartna]

@@aasastephenson1538 to be honest with you, i really don't do anything with the filter it is never an issue. it doesn't get wet or any serious debris into it I really like these compressors they are work horses! let me know if you have any other questions

[@2vgod460]

What if it’s the motor

[@2vgod460]

Just went through the same thing for duck sakes

[@2vgod460]

Man why would you take it off after you install it

[@2vgod460]

Yours from China? Mine came with everything your missing a part

[@jonis870]

if your compressor couldn't understand when to stop compressing air, wouldn't you focus on the digital air prssure sensor? having trouble with mine atm.

[@Slicpartna]

The compressor didn't build pressure in the tank, since it didn't build pressure it wouldn't satisfy the pressure switch to turn the compressor off Let me know if you have any other questions

[@jonis870]

@@Slicpartna send email ? My fronts aren’t receiving enough pressure. Solenoid makes clicking noises but after tank builds up 150psi the tears are able to have air pumped into the struts. The difference between my rears is it takes within 20psi for it to accept air into the struts. It sounds like my front struts system are failing

[@frankmontoliu2341]

You didn't start the compresor😢

[@2vgod460]

Funny watching him do it wrong

[@2vgod460]

That would not cause a problem min problem your compressor engines gone
