This makes sence. I'm known a little bit about design of your LF's since Stephen wrote me alot back in the day. Unfortunately he went to shade without even saing Goodbuy. To the moment i mostly went through all the chassis of my military Mack which is pretty similar to what you have in your pair. Also a big progress along Lanova engine is achieved. So when you're more close to initiate that project feel free to get in contact. Unfortunately it's complicated to me to get British visa. Otherwise I would be too likely to show up in person to look at the trucks. The AC seems to me as a really nice project. Pure mechanic, a pleasure to restore.

I'm looking for a pair of good front fenders for L-model. But Fl is too long ways off for checking them out and transporting.

Wow! Nice environment. I like the Volvo and that steer axle

That sounds really sad. Hope you keep the track on anything like that if shows up. Any progress on the LFSW?

That's the question flying in the air. Worth to make a call? As for me I'm afraid doing that. Because if the cost is attractive I would get plenty of rambling thoughts.

Great looking place, put on the list.

Looks like a good purchase. And nice to see old photos.

Great looking classic pair! And a real pleasure to see how that gentleman cares about his trucks. At least about restored ones. Have never seen any in person but the pics always bring me to take my hat off.

Yes, that's sure for the same reason. I would expect the elephant ears (trunnion support brackets) made of aluminium also used on your truck. The point is the relation of unsuspended mass to the suspended. As lower the figure as softer the ride (less hits, vibration etc). So for a hobby reason (no worry for the total weight) both is good to minimize unsuspended mass or to increase the suspended. Quite funny when someone comes to my place and see truck parts he use to talk how to make better one thing or another. And sometimes when I ask why it's better the answer is "It's lighter". Than you observe quite funny reaction when my words are "The heavier is better"

I've got good berings of the pinions and the cross shafts the small bull gears cut on. Only the diff ones was the issue. Bought them new both for the NR and the R.

I took apart the most of Canadian assembled 1988 R-model with Neway airride. Found that all the big suspension brackets together with crossmembers were assembled with Grade 5 (not Grade 8 ) body bound bolts. Seemed like the chassis was assembled at the factory that way. The fuel tank hangers and many other attachment brackets were installed using common style grade 5 bolts.

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!
