It was a prototype, rebuilt from NM8D1195 and took its special model name NN-1. Together with a renumbered chassis # NN8D1001. Equipped with Cardox carbone dioxide firefighting unit to be used as airport firetruck. Bart's book, page 71. Getting deeper in reading you can find that NM-2 series (straight front bumper) had chassis numbered NM8D1088-1194 and NM-3 (curved bumper to clear the front towing hitch) were NM8D1196-1299. There's a note that a "missing" chassis 1195 was belonged to that converted truck. But no pointing out it was related to NM-2 or NM-3 series. Actually NM-2, NM-3 etc. series just meant a lot of trucks purchased by some sertain contract. So probably that firetruck was not included in either of those. And if so it's not correct to call it as NM-2 or NM-3.

I think the reason of using aluminium pads was tp minimize the unsuspended weight. That might be actual for a hobby truck if planned to bobtail the most.

Be careful! It could seduce mackoholizm.

Jim, I have that picture saved on my hard drive since you posted it once before. But nice to see one more time anyway. One of the best looking trucks! My only sorry KamAZ didn't happen to produce them

I mean the races of the bearings the interaxle diff assembly (with big bull gear) spins on. Those that attached to the housing by two big clamps, like mains on a cranckshaft. I found them badly pitted in 3 or 4 R-model diffs I've taken apart and 3 of 4 diffs of military NR models I restore. Too large scale of damage to the units which were seen in a working condition until I took them apart. So seems like a typical issue just not many folks are familiar with since not many get that deep into their trucks. Those races have very special style. One has threads for a nut to set pre-load and another has a flange. Both are expensive. What was found interesting to me those on the NR (made in 1945) had Mack part## on them and none of any others. The bearing cones were made by Timken. So seemed like Mack produced bearing races(!) at some time. My original guess was they couldn't hold the quality good enough for such precision and wear resistant product such a bearing is. But those in R-model carriers were made by Timken and Bower. So probably the matter is just high stresses during a long time.

What the place it was at?

Ufff... I'm not that tall to lift those things back to life

Ran out of likes but still wnder I more like or hate to see it/ Thanks for posting. And good point on the shorts.

If the teeth have the most of their surface with rust pitting in them I would use them. If you see some teeth with the most surface covered with deep rust (actually the surface is gone) as I found at many spots I would look for a swap. Not sure which kind of carriers you have (actually don't remember) buty if they're multiple bolt (24?) mounting pattern the bull gears seem intercheangable with CRD92/93 units which are pretty common being used in R's, DM's etc. How are the diff bearing races doing? I told you of my experience finding them pretty rough in no less than 8 or so Mack diffs.

Time goes unbelivably fast! I remember green RW project but expected to hear it was done a couple of years back no more. CL seemed as even a closer event. Good luck on freshening up that huge monster. And sorry to hear about your loss.

She's pretty!

Same to her Tommy, hope she's doing fine.

Happy B-day Tom! And thanks for the pics!

Looks excellent on my screen!

Drool, drool, drool ! Are the front mounting areas hard enough to keep them original?

Great cat asses! And great T-shirt! And the great job at all. Also great to see the familiar faces. The only thing I didn't figure out - were the buffalos walking around the trucks??

Wish you to live forever to fix them all Nice truck!

It's early series NM-1 or NM-2 produced in 1940. A rare beast, only 87 examples of NM-1 and 107 of NM-2 were built. Sure re-equipped with that dump body. If my memory serves well that picture was posted earlier by Al (57BCR) and he stated it was Celli construction company truck. I might be wrong on that though.

Great photo. The cab looks custom made by some facility. It does not look like a home made cab and I think I saw similar ones on other modified NO's.

Ok, we don't

Thank you. Prob the sun made it looking just about as real diamonds. I'm not a real fan to polish aluminium. Have way beyound of enough to at the moment.

Grabbed this somewhere on the net some while back.

What are those rear fenders? I don't remember any store offering such style. Look made of SS to me.

A few more pics from someone's gallery. Not almost sure the chassis relates to the truck but all the files were named in the same manner.

This is how a factory B-model looked with that setup. As I was told the front axle and the transfer case were of the same style as Mack NO had. Maybe excepting the gear ratios. For some reason I think the frame rails are stepped at the front to clear up the drive axle. NO was made that way. But I'm not sure for the B.
