Saw that truck on another webside. Rare to say the least. Can't imagine spec'ing a Toroflow in a piece of fire apparatus! Has anyone ever seen one of the big 637 V-8 Toroflow's? I never have, though I have seen the gasoline 637 V-8 before.

Yes it is very easy to use.We have been restoreing this truck and had removed the entire fuel system from the truck including the fuel tanks right up to the lift pump to paint the frame.We fitted new filters and fuel lines.We did fill the filters with fresh fuel.we were advised it could be a bit of a nightmare to bleed as it had been sitting there for almost 6 months.After about 1 minute of hand priming the truck started first turn of the key.We think the the check valve helped a hell of a lot.....

Half to have you back always enjoyed your posts. Thank

The why, when they have killed for less, was he not even arrested? You see what you want to see to bolster your own views. But ask why no arrest and paper trail that would prove it to be true?

I don't find his uncivilized behavior humorous. He thoroughly embarrassed himself while vandalizing US government property that my tax dollars helped pay for. I take offense at that. I don't see a fake smear. The videos (different angles) display the event as it happened. I see a nutjob maniac with too much spare time on his hands.

Yes, 75W90 or 80W90 is fine. I recommend Amsoil Severe Gear 75W90.

Funny that, he wasn't arrested, the video ends with him standing un cuffed on the side walk. Labled as "appears to be..." Humm Could it be if it was him and they show that he was arrested, there would be a paper trail to confirm the truth of the video? At very least an arrest report and a bond ruling by a judge. It has fake smear written all over it. Spitting on a officer would be assault, Kicking out a light destruction of gov property, but these kind officers just let him walk? Look at things will a little more open mind. It falls apart on the face of it.

I doubt your air drier is compromised in any way, It is way thicker steel than the fitting are. Worse case buy a rebuilt bottom cover if that is badly corroded. You can change that "in situ" with the drier mounted to the truck. Changing driers (when you don't even know if there is a problem) but saying you don't have time to do what is obviously bad, is poor priorities. You've got an air tap on the lower fitting, apply shop air to above gov cutout pressure and see if it pops off! While it is building up listen for air leaks, and spray the hoses with soapy water. If your going to make it on 150 mile/week, you got to spend your money wisely, I see you jumping at things without determining if they are the problem or not.

trust me, it's a tight work space. back in around 2017 or so, the new pinion 'nut' arrangement had a bulletin out. they would come loose for no reason.. and of course Waste mgt and Republic had a bunch of the MRU chassis affected by this issue. We got our practice.

Still well into the range of at least a 3/4" torque wrench, which is going to be damn hard to use while under a trash truck!

the yoke bolt on Mack rears torques to 550 lbft

My point is still to focus on what is likely to shut you down, oil on brake cans isn't (unless the inspector is a real dick) Oil soaking brake shoes will. Air lines on the verge of failure will also get you shut down in an inspection even if they don't fail on the road and shut you down. So why if it only runs 150 miles in a week, can't you address some of these looming problems? There is a lot of oil in a differential, part of the reason there is more than needed for lube is to cool. A qt or two low isn't going to kill it. If it were I, I would pay a shop to do the pinion seal (as other have recommended) and use my time to address the other issues. While a torque multiplier is a good tool to have when working on stuff that needs to be torqued higher than a 1/2 torque wrench can reach, it is expensive kit to sit on the shelf. It is much more versatile then a 3/4 or 1' torque wrench because you can use it in tight spots that the long handle on a torque wrench that can go 600 ft/lb+ can't be used. Look, I know what it is like, I started with one truck, and had to prioritize repairs, I see big problems if you keep jumping problems without resolving any completely. I see real potential for a tow bill in your future, and trust me, you don't want that. It would be cheaper to pay to have the job done than it would be to "Kit up" for this one job.

That makes sense that its a check valve. Primers are usually on the lift pump as you noted, but that setup looks like it does have better access.

My truck deals with alot of snow and wet salty road slush that get frozen and packed into the frame rails and everywhere underneath. Current have 1800 lbs of that according to the scale house at the dump. It took me a day with a torpedo heater to get the fuel line to where I could get it out. The fuel problem is still there so I have ordered a new lift pump and just replumbed the electric back in. The same issue is going to be changing out the air line from pump. In looking closer at the dryer and am pretty sure it is going to be junk from the corrosion from all the road salt. Going to pick up another one before I have the air lines made in case I need to route the lines differently. After cleaning the frozen slush out from around the rear of truck I noticed that the pinion is leaking pretty bad. Brake cans have oil on them. In checking oil level it is lower than I would of liked to of seen it. Finger crossed I didn't mess up anything inside the differential. Good time to do another gear oil change also. My truck only runs about 150 miles a week with 2 trips across the valley of about 45 miles round trip.

Theres no number on the T piece except what can be seen in the picture.It is a one way valve.I spoke to the previous owner who toldme the hand primer was originally on the lift pump but it was difficult to operate so his mechanic made that set up.The one way valve makes it a lot easier to bleed the fuel system.This guy ran a few F 700s back in the day and this conversion was done on all of them too.The one way valve has standard Mack fuel pipe threads...The first picture shows the original position of the hand primer on top of the lift pump.Hope this helps you....

I sent Andrew in Australia a few bottles of hot sauce last year, I think. Might have been the year before last. I call him Andrew in Australia because his name is Andrew and he lives in Australia. Anyway, I think it cost about $50 to ship it. Might have been twice that much, I don't remember that either, but he said I spent too much, I shouldn't have sent it, etc. And I told him that it wasn't about the money, it was just the experience of me sending my own hot sauce and him having it. In Australia 🦘 Kind of like when I wanted to stop at the Big Texan Steakhouse before I retired, but never got a chance to. Closest I came I lacked an hour of driving time to get there. Stupid ELD. And people said "you didn't miss anything, it's just a tourist trap, you can get a lot better steak a lot cheaper at other steak places, blah-blah-blah". And I don't doubt any of that, it wasn't about the steak, I can probably cook a better steak in the back yard, it was just about being there.

Reuters is reporting that MBS (Saudi Crown Prince Mohammed bin Salman) has told Iranian President Masoud Pezeshkian that Saudi Arabia will not allow its airspace or territory to be used for military actions against ‌Iran. Meanwhile, Turkey is asking the US not to attack Iran, but discuss each issue one-by-one so as to not humiliate Iran's leadership. Turkey should never have been invited into NATO, and to think we have nuke B52 bombs stores at Ankara.......what could possibly go wrong. https://www.yahoo.com/news/articles/top-turkish-diplomat-says-iran-074034095.html

Hadnt seen that one yet. I still think its B.S. The D-crats will come out later and say it was a real world training event to see how reactions will be in case it really happens.

one report said it was cat piss.

Glad to see you're back Swishy!!

BTW, unless that pinion seal is gushing oil, I'd put my efforts elsewhere before dealing with a "wet" seal. From what I saw of the airlines on the drier, that is much more likely to either get you shut down by DOT or leave you stranded. A damp or wet pinion seal that is not soaking the brakes with oil might get a mention on a inspection report but will not leave you stranded. You can check the oil and top off as needed, but a bust air hose leaves you dead in the water. Also, how did you make out with the fueling issue? was that fixed when you replaced the hose, or are you still running the electric pump?

Torque multiplier and a 1/2" torque wrench. That is how I do mine. Torque multiplier has a chart showing input (torque wrench setting) for desired output.
