And speaking about yellow one considering it was seen in Petersburg VA region I would suppose it was Keystone Truck and Tractor Museum example.

Once i investigated leftovers of the original glow box the housing was metal and the lining was canvas. Probably the same material as was used for seat cushions.

I belive Hendrickson made them but doubt they're still avalible. Hendrickson was an OEM supplier for original Mack bumpers so quality would be right. Personally I have no ideas where to pick one up excepting ebay. They show up there from time to time. Also keep in mind there were two very similar styles of R-model bumper before and after 1979 (or so). The difference was in the mounting holes pattern since different front spring brackets were used. I don't know which one would correctly fit a U-model probably the early one and the most options I saw avalible (in chrome) were for the later series trucks.

Those on white plasic were a real treasure with no chances to find just a couple years back. Since that good guys at Watt's Mack custom ordered a portion of them somewhere and currently they're avalible through their web-site. Cost is pretty reasonable either. I purchased a pair myself. I don't know if they're avalible on a limited basis or not but there were not many options on Mack mud flaps during the recent years. Another worth for concideration option is black heavy rubber flaps also from Watt's store. They aren't colorful just white print on black background. But they're correct style with dogs facing each other and rubber. Also quite reasonable cost. Vlad

Is your truck a single axle or a tandem? Tandem B's utilized (in the most cases) the same style carriers as later models did such as CRD92 and CRD93. So plenty of different ratio diffs could be swapped in. Sorry no help with single axles.

Thanks, interesting points.

Best B-lated B-day wishes! April is a nice month. And doesn't seem as a bad time to stop doing job.

In Europe you're seldome to never seeing a tandem tractor with so long wheelbase. My guess the truck was a straight truck or a chassis reequipped with the 5th wheel. Or a custom ordered one but this is not a new truck. Nice 14L animal.

Yup. And dial checking its center when installing for the cut would allow the belt grooves exactly where they should be.

Best B-day wishes!

Couldn't the pulley being put into good shape using lathe? They're cast iron parts in many cases and may have enough of meat to cut off.

DMM had different ratios in the transfer case to supply the torque to the front axle. Front axle's diff ratio was different than rear diffs so the transfer case was designed to compensate the difference. Actually there must be (slightly) assymetrical interaxle diff used. I remember I saw multiple those ratios in some brochure and thought it could be done due different styles (vendors) of front axles used in DMM's during the production years. Following logic you're right about 6 wheel full time must mean interaxle diff. And it would compensate some difference of front and rear tyre sizes. But usually it works well when you drive slow and not for a long distance. Otherwise the transfer case may get overheated due to constant spinning of the interaxle differential which is not supposed to be.

PAI supplys R-model door glass either. But clear glass only, no green tint. Mack part# is18QX416 for the clear glass and 18QX416P2 for green. PAI offers FGT5785 which is supposed to be similar to 18QX416. Both L and R door glasses are similar when new since they don't have metal attachment plank.

Do they do cardboard liners? Or any newer material such as ABS or so? My (basically L-model) glove box insert made of sheet metal but I'm not sure on the kind of the liner. Anyway thanks for letting us know.

To sorry to hear about the happened.

Uggh... Just checked in and saw this thread... Rest In Peace Ed. As you once typed, nothing ever disappeares completely.

Congrats on the first start! Didn't you bother the injection lines so they kept fuel in the injectors? Looked like pretty easy start for newly assembled fuel system.

Yes, as said above. If a valve's leaky it would allow the fuel to run back into the tank and also cause loose of pumping allowing the fuel escape that same way instead of traveling to the injection pump. The matter of the belts jumping could be pulleys out of center. Or unevenly worn grooves. I never meet such issue just figuring. Maybe uneven hardness of rubber in the belts due to drying out during storage?

They're still avalibly new and Watt's Mack used to have them in stock. But the costs became not too pleasingly in the recent years. The rocker panels I used for repair of my R688 cab were 169QS43P3 RH and 169QS44P3 for the left. As for the roof skin keep in mind there were shorter cabs (pre- 72 or so) which had shorter roof sheet. So look for the later (or the longer) one. Vlad

Almost true

What are those green tint glasses? Newly made?

And the one in the initial post is a very interesting find.

I'm pretty sure Jim has...

What I found locally is industrial carpet with rubber (poliurethane?) backing and they claim I could bend it in shape applying some heat. Haven't the job done yet just going to put my hands on.

As I said in my previouse post - unbelivable and interesting! Currently I'm on my very first steps on Farsi. Seems to me of not much worth of a trip in those lands with no local speaking skills.
