Well, after Hippy's comment I figured out which B-model that was. Great looking truck.

I remembered the moment but almost forgot the background. Many thanks for the picture. Ummm...  I don't mean the ice cream cone one.

F600's had chassis rails of the shape similar to a R-model.

F700's had their special rails but I observed the later years truck only.

So would be cool (to me) to learn which style early F700 had (if they were existed at all?)

Of possible cases popping up in my mind could be the same rails as on the late F700's, possibly RD rails (same front end shape as an R but with higher section) or just F600 (R600) rails with inner channels.

The truck in the add must be a cool animal with V8 screamer. My personal preference is Mack engines in a Mack truck but two strokers is exotic overhere. Don't even remember of any running truck in the country with a two-stroke Detroit.

That's what we do here in Odds and ends Vlad, you know that. I'll even hijack my own thread-

So, it must not pay to go to Home Depot on Sundays, especially Easter Sunday. The last time I was at Home Depot was when we went to get a freezer last summer. The starter locked up on the red Ford pickup when we were leaving and I had to get it towed. I filed the burs off all the teeths on the flywheel and put a starter on it, been starting ok ever since. 

Today Zina wanted to get some flowers so we drove the Zinamobile Nissan Titan to Home Depot. And on the way back, about halfway up Oxford Furnace Hill it just quit. It would start and run for about 3 seconds then cut off. I coasted it back down the hill and into a driveway so it's off the road. I called a ride to take us home and a tow truck to take the Zinamobile to Lynchburg Nissan. Sounds like a fuel pump issue.  Good thing it has the top to bottom, front to back, complete warranty on it, even the towing is included. Only has 21,000 miles on it.

Doesn't sound like a nice chain of events. I'm not ready to choose the best comment of to not go to Home Depot at all or to not drive a Nissan or any other. One thing is for sure if Zina wanted flowers you should go and make the purchase.   ̷A̷n̷d̷ ̷I̷ ̷g̷u̷e̷s̷s̷ ̷s̷o̷m̷e̷ ̷f̷l̷o̷w̷e̷r̷s̷ ̷c̷o̷s̷t̷ ̷l̷e̷s̷s̷ ̷t̷h̷a̷n̷ ̷a̷n̷ ̷o̷l̷d̷ ̷I̷H̷ ̷t̷r̷u̷c̷k̷

Hope the warranty deal will go smooth.

Isn't that a F600? 

I honestly am not a specialist. But those tortion bar attachments below the headlight panels give me that thought. I can't see the other pics to check out the frame rail shape though.

 I was chasing a bad vibration, I used to be able to run the truck at 50-55 and it was un-drivable above 35.  The rear shaft had bowed badly, not from any hit but from running above the critical speed. The more a dove into the problem, the only thing that made sense. I started laying out a replacement shaft and once I ran it through the Spicer calculator, I found stock would not work. The hard part was U joints were obsolete and I had to switch to a more modern joint. That meant changing yokes and had to make the tube a lot larger to make it stronger.  Ended up putting more in the shaft than the truck cost me 20 years ago!

My only thought is when the truck was produced they didn't expect it running faster than 35. Or maybe they saw that possible ocassionally and that is why the shaft has kept its place on the truck, not on the ground.

Speaking the expences it may be seen as you threw some coins into the shaft repair instead of having a zero worth truck. As long as you could not drive it anymore. And now with the new shaft you can.

It seems though we are hijacking Tom's thread. Regardless the subject has some relation to it.

Yes, of course she remembers you. Every time I'm on BMT she asks if I've heard anything from Vlad. 

Wow! This makes me smiling ear to ear wide!

I may also mention I ocassionally wear a F.L.Moore cap you presented to me and make marks in a desk copybook by a Kroger Pharmacy pen.

Those were the 12.50/38 Super Swampers. I had a set of 38s and a set of 36" Swampers so I could run it in 2 different classes.

That's cool. I never drove anything larger than 33x12.5R15. Macks don't count. But I drove those for whole 10 years everywhere, both in a forest and on highways in Europe

Thank you Vlad, that put a big smile on her face! Dave liked that 2 tone brown paint job too, it is an eye catcher and that's what she said she wanted. The one in the picture I posted used to be parked in the same spot in Macungie every year, but it wasn't there last year. 

Glad to hear I could please Zina. Say hello to her if she still remembers me.

I saw that brown L-model at Macungie. The colors looked nice and the cleanness of the paint job overall was impressive.

One thing I found working out a new driveshaft for my K-7 that early on  and I don't know when it was learned, that driveshafts were made that were well into and above the critical speed.

 My K-7 had the OEM shaft , I checked against the parts list and dimensions, it was as built. I then plugged those very same dimensions into Spicer's calculator for critical speed and it was in and above during most of highway running. 

Sounds like the critical speed is a feature of Spicer only. And the rest everybody just don't know it exists  Sure kidding. It's fun to kid until your prop shaft would go off to the ground or hitting the underbody.

Seriousely that's very interesting point you mentioned. I just haven't cut a bit of time from my shedule to check out the critical speed for my WW2 Mack. The shaft is stock though, has intermediate hanger I've revised and the joints are good. I didn't modify anything in the tranny, only put faster carriers. So improving the speed wouldn't affect the prop shaft revs.

The tyres look no less than 37". Must be a cool dirt cruiser with so small chassis weight.

I would imagine so.   They also did some "improvements" to the flyweights.  Not sure what.    But, the long and short of it is, throw some $ at these pumps and the surging can be calmed down.

In my case I suppose I would be the only person in a pump shop to explain what to do with "that piece of old junk". So try to scratch up a few bits of info.

Would be also interesting to learn how to increase the maximum PRM setting from 1900 to 2300 what was told as a safe figure. I sure don't pretend on you to describe that. Just thoughts on the matter.

I would say it's a bit early time for congratulations on the purchace so I wish good luck on the purchase!

Really nice looking truck and especial combo of a single axle and integral bunk. Gasser may be also seen as an exotic thing, hope not much worries on the fuel milage being driven ocassionally to shows.

Another great point is that Zina initiated purchasing a big toy. You must be a lucky guy with that. Told her I would also remove that grill protector (probably the community would blame me for that) and brown colors combo would suit the particular truck very well.

Thanks for the note. I'm going to revise my Ambac pump off E6-350. The idle was floating and the rest seemed Ok. But bench check and other possibly needed jobs are on the list.

I will Google the "rack buffer" to figure more about the issue you fought.

I have a pair off a LS firetruck

 

PM sent.

I think you can correct that offered style into the dome shape by machining. Looks like plenty of meat under the edge to mill or grind off with no worry on structural steadiness.

Shivers...

Saw the video on my local news page.

The heigth of the bridge to fall from and the temp of water don't give good chances to survive.

Don't you have the LH headlight bracket upper portion for a L-model with a soft nose?

My one was butchered with a torch where the light hemisphere mates.

Vlad,

Think these are the Wheels you are referring to. They are Accu-Ride not Alcoa. They were an option on the Ford 9000 back when? I had to have then reworked for stud pilot from hub pilot so they would work on the old B model. It took some searching 15 years ago to find 10 good 24.5 rims even back then. They have the oval 5 holes but do have the correct wheel contour of the old Alcoa 5 hole split rims. Second photo is for comparison. At a distance you would have to take a second look to see the difference in the holes. 

Yes they are, exactly.

Speaking particulary I was impressed by the look of those wheels on your B-model. Saw them in person at Matt Pfahl's place in 2013 when the truck was even not finished.

I didn't know you had to redrill them for stud piloting, never knew they were avalible in both variations or hub seat only. A few month back a set of two showed up for sale locally. They were taken off a certain American tractor, IH or Freightliner the most probably. Not bad condition over all. I have no particular use on them at the moment. Thought they would look cool being installed on a steer axle combo'ed with steel Budds or Daytons at the rear. These are 22,5 though. Not 24.5. But that is a common tyre size overhere, always easy to locate. So now I just have one more bit of a game to play.

My apologies Paul, looks like your right.

I looked the Kenworth wheels over on the 3rd pic in the thread, where it's represented at the exhibition stand. Originally it appeared to me that there was that step over the lug nuts like a common Alcoa had. Now I looked better and it's probably a trick of reflection. Or possibly a bit wrong way of polishing applied to the particular wheel where the central flat spot got an edge passing to the hemisperical portion.

I had a chance ocassionally accuiring a pair of 22.5 tubeless Alcoas of that smooth style with 5 holes. The difference is the holes are oval not round. Also look cool and vintage on my mind. The issue is they're hub piloted style so I need to redrill them. And sure grinding and polishing is unavoidable.

Yes, this is what I meant.

I would agree Vlad

 

The style in the link above are much better suited

Apparently no demand so were only made for a short while 

 

Paul

Are you sure the wheels on the Kenworth are different? To me they look very similar to the product we discuss. Maybe the hole size is a bit less.

I'm pretty sure tubeless Alcoas with smooth dome face with 5 round holes were avalible at a certain time. If I'm not wrong Mike Superdog showed or pointed them out in some thread. Unfortunately there's no way to ask him anymore.

CS Midliner has similary looking hood.

But I have some doubts on that hood to work as the direct replacement.

To personal taste the 1st pic look is better.

Or Mack green instead.
