LOL!!!!! Now that's funny. Yes, it can be a "undetermined" amount of effort to steer depending on the situation. I'll keep mine though. Just my .02.

If you use your bellhousing then it will bolt right up. If you try to use the twin disc-like from a 5-6 speed(deep) bellhousing it might not. Be much easier to use your quad. All depends on what 237 you find. Mine was lucky and had single disc bellhousing. Most won't and you will have to indicate and redrill the dowel pins to fit your bellhousing. See the bellhousing? It has lower right starter and was for single clutch. It supposedly came from a firetruck, with how the oil dipstick was aimed I would guess it was a CF(cabover). It's for access from the rear, not the front like an R Model would be.

Air pressure switch. Likely for the low air light on the dash. By the markings it comes on at 60 psi which is about right.

Nice work!

I noticed the missing battery box also, unless someone put it on the drivers side for some reason. The tank just looks a bit small for air start. Guess they thing 30 gal is enough. Most are twice that length. But nothing bigger would fit.

Small round doesnt look big enough for air start but maybe it is? Maybe wet line? Wonder if they moved the stock tank back to make room?

Sorry, copied/pasted all the info but forgot the link. Thanks Jim. It's only a few minutes from me and I've had thoughts of just going to look at it. Not that I have any need for it but the money is pretty cheap. I'm thinking they asked more for it earlier this summer? Oh how the township would raise hell if that sat in the driveway for more then a day LOL!! I just realized it is a "Gangle" truck. They have been around for years and I know they run some really nice Mack dumps(typically red/black). I used to frequent the historical equipment shows and they would bring some old shovels to play in the dirt. I remember Jim Gangle on the newer trucks. Butch must have been dad? brother?

I was terrified about my triplex, but I have found that it does fine overall. Yes, I still drive it like a Thermodyne, keep it above 1500 rpm and nothing sounds like it is complaining. Some have said that a 237 won't pull higher RPM(up to 2100)very well, but mine is awesome. No complaints at all.

I did put a flipper valve on it from stories I've heard. I turned it off but made so little difference I just leave it on. Due to the lash(movement in the valve) in the torque valve it always has a touch of looseness but I don't let it bother me.

I like my air steering. I put up with armstrong for 13 yrs, this is a nice improvement. Perfect? No, not by a long shot, but better. You have to get used to the random "feel" of it.

Nice score. Ya, you won't know what to do with all the power over using a pickup truck.

Not too shameful. I could do without the fire engine yellow! Ditch the wagon wheels for some old school alum slots and it would look more the part. Scale wise it doesn't really hook hateful and some of them really mess that part up. Ya, I'd take it.

I'm going to try again to get that check valve off the injection pump. If that was leaking off then maybe that is why the readings fluctuate some?

Back up for sale again. Been awhile since I saw it posted. I think the price has come down a bit? 1975 F786ST Mack - $1500 (Copley) Purchased in 96 for family business and its time for retirement. At the time it has rebuilt 300 Maxidine motor that is unstoppable. We've put less then 100k on it since. The bunk mattress still has the plastic. It needs lots of things refreshed but it is running good and drivable. It's been and current stored in a locked barn for.....

My 237 had a finicky hand pump on it. It basically works two check valves to pump. I pulled it apart and got some fuel in there to lubricate things and presto it started pumping. It will not feel like it is doing anything until it gets some fuel pressure built up. So don't give up when it just moves up/down easy. It is moving fuel. Once it gets some pressure built up it will get stiff. I used a gallon milk jug to start my 237 in the garage. Just put the draw line and the return line in the jug and pumped it up. The few times I've had to hand pump my truck I've never had to crack a line. It just lights off and runs fine.

Time to find a 237. Believe me you won't regret that change!! I grin from ear to ear when I get behind the wheel of my truck now knowing it has some balls to it. Have these guys upgrade your stock clutch material: http://dwclutch.com/ I had $300 in getting mine rebuilt last winter when I put my 237 in. I will say it is a bit chattery at times but very drive-able.

What's all the fuss.......I used to eat the paint chips from those bridges growing up and look at me?? Nuttin' wrong with me!!

Ya, but from 1955 to 2015 seems like such a long time..........LOL! And now it's here.

Wasn't it Back to the Future 3 where they showed the Cubs won??

Ok, fill in the un-edumicated about loosing a piston. Common to these for some reason? Do I recall something about a 2 pc piston or am I off on a tangent someplace? Just curious.

Well, the last trip out this past weekend was a good one. The truck ran flawless and seems like it has a bit more Umph. Fuel pressure never dropped and I ran the drivers tank down to 1/2 tank or so. If there was an issue with the pickup tube I would have expected to see an issue. So I'm thinking either the pump was bad or the filters were that clogged up(even if they looked okay). My buddy says he was surprised at how well it ran the hills and we ran 70 mph without breaking a sweat. I actually passed a line of traffic going up a pretty good grade running 70+ mph and still accelerating. I even turned to Karen and commented to her about how well it was running. I got a reman Mack pump for it today. I put it on tonight and fired it up. Still only about 15# at idle. I can slowly rev it up and it would randomly slide up to 20# or so. Not every time but a bit more then I could ever get out of the other two pumps. Still think there is something else that is messing with it. The return line check valve? I haven't been able to unscrew it yet, but now that I don't need the truck I might get a bit more persuasive with a bigger wrench.

Looks like a really, really cool place to visit. Just need time to run down there.

I'll check with him. Thanks.

What a tragedy. My condolences. http://cbs6albany.com/news/local/tow-truck-driver-hit-and-killed-near-exit-29-of-nys-thruway

Talked to local Mack dealer. I need to use the serial number I got from a member to chase down the right pump. Easy enough. I also think I traced down my surging idle issue. The last trip it was getting really bad and by the time I got home it really had to play with the throttle to get it down to idle. I looked at it tonight and think it was my hand throttle bracket was getting in the way of my linkage and holding it above idle. With the playing I've done with the linkage it was getting very close to the bracket and I the bracket was just slightly rubbing the linkage and holding it. I cut the bracket and redirected it to eliminate that problem. I started the truck and it works fine now. No fluctuation at all. Just a steady idle speed. I have one more trip this weekend and then I'm done for the season. I'm going to run the fuel down low so I can transfer from one tank to another so I can empty them and check the suction tube. I really want to replace the tanks but that might have to wait for another year.
