York On Board Air Install summary/pics on 80

[southerncruiser62]

Alright guys some of you had seen the tank mounted under the truck at a few of the HAMOM's over the past couple months but in an effort to make trail repairs easy at Harlan I worked through getting everythink installed. Luckily we never had to use it really in Harlan. We gave it a shot as we were getting ready to leave-had to change out Barry's tires and one of Jared's for a safe drive home.

Overall I am very impressed with the setup, used one of the last few brackets greatlakes had made and though there were a few small qwirks in getting it mounted it was nothing to stop me from buying another on if they were available. Nice laser cut piece with very clean welds, but with anything when you are only making a select few of a unit and welding it yourself things tend to "shrink/warp" slightly. Nothing a quick dremmel touch couldn't solve. Other nice feature about this setup is that it uses a toyota pulley so replacement is made easy. In the pictures you will also see the new 3 groove pulley that was machined for the belt.

As for the rest of the unit well after searching through online suppliers for indivdual parts I decided on taking an alternate route, kilby sells nice stuff but in my mind it was a bit higher in price than I thought the entire setup could be put together. So I ventured out to Sears and a few other big box stores to see what they had. I found a 3 gallon unit that seemed like it would work perfect and it was on sale, so I walked out the store under $80 for everything (mostly) under the price of Kilby's 2.5 gallon tank. This saved a great deal, and as you will see already had me setup with a Atuo on/off Pressure switch, Pressure regulator, Pressure Guage, Tank, air intake side air filter, 4 quick disconnects, tire chuck and guage coiled hose, and a few misc. pieces to setup other small accesories. Only parts I had to source beyond these was the 3/8" air line, check valve and coecselating filter seperator.

I was fortunate enough to have been given a brand new never installed York 210R unit with a brand ne clutch which also saved me the hassle of junk yard searching for the unit and rebuilding or what not. I was hesitant in installing the unit as it was actually a factory 1976 FJ55 A/C compressor that would have been dealer installed but I thought I would never use it otherwise and this was ideal, hell it's the reason I bought the last bracket in the first place.

So overall the install went pretty smooth, only issue was that over thinking I checked everything 3 times I didn't realize I had installed the check valve backwards which caused a small issue when the 300 PSI hose blew up-lets just say these yorks pump a good bit of air in a small amount of time. Once that was removed and installed correctly the unit was tested for functionality, on at 90 PSI off at 125 PSI. Tank fills in about 14 seconds at 1,600 RPMS. Ran the impact on it in Harlan and other than a low torque impact it seemed to drive it just fine. Air all 6 tires up yesterday evening in a little under 10 minutes.

Heres a few pics for reference, if anyone decides to make a go at this let me know and I will gladly provide the part numbers/parts I used.

Did the tank come with the Craftsman sticker upside down, or did you specifically put it on so everyone knows you're sponsored by Sears? I've got a Husky compressor that if the motor gives up, is going to do exactly the same thing...

 

[southerncruiser62]

well since you asked, no I flipped the tank and in doing so I swap directions of all the stickers including the specs.....in flipping the tank I had to swap the inlet and drain which actually made better since now that the drain is centered on the bottom vs. being 1/4 of the way up the tank.

Greg did you have that filter on your line @ Harlan?
I know it seemed a bit oily when we were using it.

Awesome mod and fits so perfectly up under the 80.

 

[southerncruiser62]

Yes I did have the filter on but I had not yet done the oil galley plug mod yet on the york, did that last night and remounted it last night, oil blowby has decreased substantially. However I had also overfilled it slightly before leaving last wednesday so some of the blowby over the harland trip was excess oil.

It's really slick - no "oil" pun intended. I have OBA envy, but didn't have time to get it set up before Harlan to run the ARB. Maybe somewhere down the road - LP conversion first!

Greg, pretty nice setup.

Looks awfully vulnerable there or is that just the angle of the picture? I would hate to see you drop onto a rock with 50-100psi in that tank? (Course the lift / could launch you off the rock and on...but)

 

[southerncruiser62]

It's location was determined by looking at the 45 degree angle from rear bumper to bottom of rear tires, of course I am aware not every rock is bigger than the truick it self but if you notice the picture from the back of the truck you will see you can't really see the tank at eye level of the bottom of the bumper heres a prime example-see the picture it's still not visible at that angle.

 

[S4Cruiser]

Very nice...I'm jealous. Where did you get the 3 groove pulley?

...now on to search the classifieds to see if anyone is selling one of those brackets...

Actually, they tested this on Mythbusters. They dropped tanks just like the one Greg has from a small building (maybe the 10th floor or so) onto the ground and onto a bed of spikes and the results were not very exciting. No explosive release of air or anything. Kinda disappointing actually.

 

[southerncruiser62]

I wonder if the added mass of an 80 from the 10th floor would change the excitement.

Mythbusters blows. They also said that there is no way a winch cable can do harm when snapped. They do one experiment and call it quits. Getting results takes thousands of samples and experiments.
Don't get me wrong it is an entertaining show but as greg said the mass of a truck on top of it would change the game a lot.
We've also had tanks blow at work just sitting there. Every situation is different.

 

[swampthing]

I agree with you Al - one case isn't significant.
I remember the episode of the cable snapping - I believe they were testing if it would slice someone in half - they had the pigs lined up...I don't remember if it broke the skin but there was definitely a permanent indention.

I think they called the myth false due to the fact that it wouldn't cut you in half - but there was definite carnage...I won't be hanging out by one anytime soon.

Without hijacking this too far off Greg's great mod here...the issue on Mythbusters is to validate a MYTH.

In the case referred to, the myth that a severed winch cable could cut someone in half. Nobody has been cut in half by a winch cable, thus the myth. People have lost body parts but the myth that someone has been cut in half is just that...a myth.

My recollection of the episode is that the goal was to see if a steel cable stressed to a point that it would be severed (they had to create a device to do the cutting), would the cable be able to cut a human in half. They used the pig carcass since it is the most widely used as a human equivalent in such tests. My recollection is that they showed it would cause severe injury, maybe death but not "cut someone in half". In as much as the show puts the experiment into a nice package to be seen in an hour, I'd guess that there are many more "attempts" than what is viewed during each episode. How fun would that be to watch someone repeat an experiment a few thousand times to make sure the results are valid.

I find their effort to validate/disprove myths entertaining at the minimum, on the verge of real science at the other end. Obviously, "real" scientific studies involve much more testing to create validity. Yet, their experiments do provide valid results. Their recent show, trying to validate the "science" of which would hit the ground first, a bullet dropped or a bullet fired from a gun, both at the same height. Science says they will both hit at the same time and their experiment validated this.

For me, one that I found in my personal experience was the whole pick-up truck tailgate down increasing MPG experiment. When I owned my Dodge 2500 Cummins, I found that I did get worse MPG with the tailgate down and I was confused. I towed a 30' 5th wheel and bought a nice "louvered" tailgate with a cutout for the 5th wheel coupler to pass through, got worse MPG (not towing, obviously). Put the stock tailgate back on, left it up, MPG went back to where it was. Never understood why until I watched their episode "exposing" that myth.

Regardless, when I looked at Greg's tank placement, we talked about its vulnerability. It would have to be an incredible series of coincidences for that tank to be hit, in other words, bad driving. More mass upon hitting that perfect storm of coincidences would only puncture the tank with more authority, allowing the air to escape. Seeing the damage on Greg's truck from the air line rupture is a bit scary but that was at a much greater pressure than after the regulator which is limited to 120 psi if I recall correctly.

I see little risk or concern with this setup, at least for the driver and passengers. Being behind Greg, either on foot or hanging my head out of my rig, might be of more concern if I saw him backing into a nice and pointy piece of granite.

Hijack off...

I don't know what obstacle you're planning to tackle, but GET VIDEO!!!

Would something close to this do?

Yeah, that oughta do it. If you're doing something like that, methinks the vulnerability of the air tank would be the least of your worries.
