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.

Holey crapola. What a deal. Sometimes you are at the right spot at the right time. Nice job!

Well it's all there, just coming apart. I guess a good shop could resurrect it and make a pattern to something else and cover it? Not sure I would try to reuse it and cover it.

AH, I see. Interesting.

Mine was replaced some time in it's life. The threads in the seams are coming loose and it is falling on my head. The cardboard is also brittle.

Anyone know someone that has the pattern for a black pleated/diamond headliner for B model cab? My original headliner is falling apart at the seams, literally and I don't want the beige anymore. I want to make matching door panels.

Twin snorkel air cleaner? Would think that would be tip turbine?

Nice! What for powerplant? 285/300?

Great work. I get SOOO jealous when I see shiny new parts going together!!

This is my typical day at work> Making drawings of broken parts so we can make them new. Nothing that unique about that casting that shouldn't take but a few minutes with a set of calipers to make a drawing. I hope you get it taken care of.

So does anyone know the real part number for a fuel pump? Should I just hit the dealer with my IJ pump number and go from there? Something like this? http://www.ebay.com/itm/E6-Fuel-Supply-Pump-2-Valve-PAI-P-N-ESP-3598-Ref-Mack-314GC227-Bosch-0440008015-/262616166868?hash=item3d2524b1d4:g:3N8AAOSwEK9T37NI&vxp=mtr Mine has the old school hand pump on it and looks more like this: http://www.ebay.com/itm/Mack-E6-Fuel-Supply-Pump-w-Primer-PAI-EPA-3587-Ref-319GC110-Ambac-SPA22B6363A-/252530193697?hash=item3acbf8f521:g:s4IAAOSwZjJU9M2T&vxp=mtr

LOL!!! You're leaving yourself WIDE open to a real smart alec comment on that statement!!!!! My friend had a FL120 toter and don't recall seeing a shut off? Maybe I never looked hard enough.
