York on PTO (1 Viewer)

[Coolerman]

If I were to run a PTO aircompressor, I would get the alternative PTO drive, that bolts to the back of the transfer case, Spector used to have these, may still. They may be settup better for continous use. For a pump, I would rig up a direct drive from this output, maybe with a rubber coupler to reduce vibrations, and use an Air Compressor pump for a real air compressor. Buy a cheap one, or a really good one, either way, it would be a real compressor. This settup would also work well for a hydrualic pump settup the same way.

You can run both PTO's this way, you would have a twin stick PTO, the standard shaft for the PTO lever was settup for both sticks. Then you could still run the side PTO for winch, and the rear PTO for air independently.

Dedicated air compressors, OffRoadRecovery.Com EXTREMEFLOW ENGINE DRIVEN AIR COMPRESSOR Pricey though

Spector still has them. About $150 before shipping.

What advantage does this have over the 'normal' PTO setup? One thing I see is it would not hang down as low...

How could you possibly want all that heavy iron crap instead of a nice little electric ARB-style pump?

I agree it would be kinda cool, but way too complicated and heavy IMO.

I have the electric ARB pump, the heavy duty one.
You would be sad if you tried to air up a 38" swamper with it. Let alone four.

My general complaint with electric pumps is the watt to CFM ratio. Also to me it doesn't make sense to generate electricity from mechanical power then turn it back into mechanical power to compress air. In a perfect world with 100% efficient generators and pumps this would be fine, but in the Real World® you lose energy every time you convert.

It's a 1984 truck.

I swear I think I saw this truck here on mud, because I have many pics of it. Here is another view of the engine:

That's my 84. It's a Swiss model. Most of the FJs here were modified at the dealer in Safinwil with this compressor and a nice tank and air brakes for heavy-dutry towing.

I no little about compressors and still am on a hijack to know what my compressor style is called.

it will work fine.

THe toughest thing is getting everything to mesh and mounting locations

Thinking about it more I guess a regular AC pump without the big piston head sticking up would work, just plan a trip to P&P every year or two to get a replacement.

Spector still has them. About $150 before shipping.

Since I currently have no PTO output at all this has all been an academic exercise anyway. But I agree, unless you had a PTO winch it wouldn't make sense to use the rear O/P. I have an 8274.

I have never fitted one, but the benefit would be it runs directly on the tailshaft of the tranny. Unlike the standard PTO box that uses a gear, and more gears and idle shafts to get to the outputs. Also the side mount boxes sometimes have reverse, this would not work well for a compressor.

That rear mount would spin straight on through, with I presume a simple clutch, mutch like the front driveshaft output to engage and disengage. It would jut be more suited to a dedicated output like that.

I agree, but a 10# CO2 tank is more portable and lighter than a pto compressor setup. Just MHO...

 

[shelfboy1]

Why would you need the PTO engaged at highway speeds? Or at all while driving? Even a small tank will run air lockers for a long time. I have the big ARB pump with a tank the size of a 1# propane bottle and it will run my lockers through four or five cycles. One of those hot dog tanks would probably run me most of a day even on a tough trail. When airing up you would be stopped anyway.

how about the truck in the post that has pneumatic brakes and you did not specify what your use was good luck

Rusty, what year is your 40?
I have a three speed Ramsey pto that I am not using...

it has outputs to the front and back. They are not that strong of a unit but would probably work perfectly for your purposes...

I have CO2 now. I'd rather have a compressor. At the time CO2 was the cheap fast way. Now I have my rig on the trail and want to upgrade.
I'm not convinced PTO is the way, just noodling.

I have a 75, but the t-case is an Orion. I thought Ramsey was a winch?



I'm coming to the conclusion I need to get a three position pulley and put the compressor under the hood. That means the alternator will have to move to the former smog pump position to make room for a York. Or I put a regular AC pump in the smog pump position and plan on replacing it periodically.

Unless somebody has other ideas???

 

[grant5127]

Engine mount and bracket idea... although the belt routing needs to be changed to include the crank pulley for main drive source..........

 

[77TLCFJ40]

You need to see Mudrak.com. He makes a bracket that mounts where the alt is but it also has a provision for the alt. Its a slick setup.

Not affiliated, just happy with my York Bracket.

Good luck

He's in NorCal somewhere isn't he?
I'll look into it.

mudrak is a great guy dan..

Good to hear.

I still want to know what you were talking about with the Ramsey.
Does it connect to the PTO O/P shaft?

BTW I looked at the access to the PTO on my Tcase. I would have to re-route mu exhaust, again, to make room. Since I finally have it up out of harms way I don't want to mess with it.

 

[Mace]

the ramsey pto unit bolts to the tranny output on the tcase...

want a pic?

That would be cool. I'm having a hard time visualizing it.
