MD-50 Compressor

PaulW - 10-8-2019 at 08:08 AM

Good topic for most of us. Yes, I know it has been discussed before, But, IMO it needs to be a stand alone topic. Much better than buried in other threads.

Sigh: Good things need some effort to make them work better or correctly.
Yes the Mv-50 is a good choice for a handyman.
Check out this link to decide what improvements are necessary. I do not think you have to go the whole way, but just pick and choose to the important improvements that could be fatal out in teh boondocks.

I had an MV-50 for awhile. Did several of the improvements shown in the link. Nonetheless, the reed valve still self-destructed so I replaced the entire unit with a Viair 400P portable compressor.

My Viair 400P has has seen heavy use for 6-7 years filling 33-35" tires and is still going strong with no modifications/improvements necessary. About $160 when on sale on Amazon.

In my opinion the MV-50 is okay for light duty use, but just okay even if/when "improved." There are better buys for portable compressors.

YMMV

P.S. - A damaged MV-50 reed valve can be replaced with a cut down piece of feeler gauge. Go slightly thicker than the original reed valve, but not too much.

I've had a Viair 85P for about 4 years, have had no issues at all with it. I probably should have gone with the battery connect style, but so far have not had a problem using the power port. Never blown a fuse and it airs up pretty rapidly.

I really like the screw on air connection, much better than the lever type, IMO.

Pumas are indeed great compressors. Unfortunately, they take up a lot of space which is in short supply in my rigs.

JZ - 10-8-2019 at 10:51 AM

This is the one I've had for 5-6 years: https://www.amazon.com/Inflator-Portable-Compressor-MasterFl...

Fits perfectly in the center console of the truck. Easily inflates 33" load E tires.

The photos at that link are compromised because somebody didn't pay the minimum on Photobucket for third party hosting.

Here's a pic of my MV-50 box:

Ultimate high end compressor. Way overpriced but is very close to being as fast as my CO2 bottle. I would never spend the money, it was in the jeep when I bought it. https://www.4wheelparts.com/p/arb-on-board-twin-high-perform...

Yes, a crazy price...
A Nomad I know installed something like that in the back of his '03 Wrangler, taking up valuable space. I still could fill all my tires in less time with my MV-50 at $80. The MV-50 fits behind my driver's seat in a tote bag.

ehall - 10-8-2019 at 03:44 PM

Mine is mounted under the passenger seat

David K - 10-8-2019 at 03:49 PM

Nice... I would enjoy a built-in setup... There is room in the engine compartment, too. I just don't go off-roading so much, now that the road guide driving work is done. Getting old fast and I hate it! It was really nice to be a passenger in the last two Baja trips (riding with TV camera crews and celebs)!

Mr. Bills - 10-9-2019 at 11:54 AM

As mentioned above, I own a Viair 400P portable compressor.

I also have a Viair 400H mounted under the hood of my jeep.

The 400P and 400H have identical output and can easily handle 35" E load rated tires. They are significantly faster and run cooler and quieter than the MV-50 I have on my parts shelf, although an engine driven compressor or the ARB twin compressor would both run circles around my Viairs.

Mulege Canuck - 10-9-2019 at 07:55 PM

I have two VIAIR 00088 compressors. I use to have just one. I run my tires at 70 PSI due to the weight of the truck camper. I air down to 30 PSI if I am driving on soft sand.

The problem was when airing back up to 70PSI, the unit would over heat. It would be fine for two tires though. So I bought another one and I switch out the units.

PaulW - 10-10-2019 at 07:26 AM

DK, Thanks for the pic
Ed, I use a 20# CO2 tank and no one in our groups in Colorado or San Felipe can ever beat me in airing up from 12 to 28psi on my 35x12.5x15 tires. I use a fixed reg, Powertank gauge assy I got for a pittance. and a 3/8" hose. I can even beat the York compressor guy.
All others, Keep the compressor suggestions coming.

sandpoint - 10-10-2019 at 12:02 PM

I have the Vivair 450. It's a 100% duty cycle model. It's certainty expensive, even on sale, but I've had it long enough the sticker shock has worn off. It has quality fittings and accessories. It fills tires resonably quickly and hasn't had a problem filling multiple vehicles worth. It's reasonably quiet too. The bag it comes in has more than enough room to put it away without duplicating a factory small-as-possible folding job. There's plenty of room left over for the valve stem deflator tool, tire plug kit items and extra pressure gauges. I like having it in a bag so I can take it in whatever vehicle I happen to be riding in.

Ya. I use the bottle but love having the compressor for back up.

I have the Viair Extreme (2 Viair 350c compressors with a 2 gallon air tank) on the TJ Rubicon. I bought an inexpensive Harbor Freight portable compressor for the JT Rubicon. When I go to 37" or 38" tires, I may upgrade to ARB twin compressors.

Hey Ken what motor did you get in the Gladiator?

I have the 3.6l Pentastar - the 3.0l diesel hasn't been released yet.

David K - 10-13-2019 at 02:19 PM

Would you even want a diesel, Ken?

I would! High torque at low rpms, better fuel economy, longer engine life, more stable fuel if it sits for a while, and oooh the aroma!

David K - 10-13-2019 at 02:37 PM

Noise, smoke/ smell, diesel fuel costs... are things to consider, aren't they?

Exhaust smell is horrible - it's punishment for other drivers. The cost will be $6,000 more. I would need to carry DEF on long trips. Different spring rates for suspension coils on a pickup with an already heavy front end. I'm not completely sold on having the diesel. I am sure they will sell like crazy next year for their towing abilities off road utility.

JZ - 10-13-2019 at 08:53 PM

Smoke, smell? Cost more at the pump?

I see some posters here haven't driven a diesel since the 90's.

But they are driving trucks that you buy for your kids in HS, so not surprising.

PaulW - 10-14-2019 at 07:25 AM

Just my opinion after driving diesels for many years.
Diesel No any more for me.
Cost per mile is poor per gas. DEF is a pain. Service cost is much higher than gas.
The only attribute is towing ability and would be only a little better than a comparable gas rig.
Ken got the correct motor.

Ken Cooke - 10-14-2019 at 04:31 PM

On the last leg of my Copper Canyon run, Bill handed me the keys and I drove his 2000's F250 diesel from Phoenix to Riverside. It had choked all of the Jeep drivers for two weeks but it had serious power on tap. For a Jeep with it's top off, I prefer gasoline.

High school pickup? I don't know many kids receiving $65k trucks, do you?Haha

I guess the higher the monthly payment the more of a man you are? Must be the neighborhood he lives in, nothing but Jones'. Or, small manhoods.

37's are not a problem with the 8 speed automatic and 4:1 transfer case gear reduction. The rear axles are from a Ram 1500 truck and have better reported stopping power than a JK with the Big Brake mods. Heavier axle tubes than a JL, better cooling than a JL. Guys are running 38" Patagonias without any issues - completely stock (w/Tazer). As a matter of fact,The Gladiator Rubicon was designed to run 35's completely stock.
