Couldn't they be of different thickness? Visually they're one style indeed. Would be interesting to check out the parts lists.

Wow! Interesting. I used to see a different setup on RW2.

Yes, we are all busy minding our own businesses. Happy B-lated B-day Paul!

Uggh! Italians have stolen a Mack color! What a shhhame!

Yes, this crossmember is supposed to be on the rear. I have a similar one on the rear of my MH. With spicers at the sides and put with the dish up. Very probably you have a similar part as the cab support but I expect that to be a single beam. If that one is double like the one in the pics I'd like to see your cab air ride setup. Good luck on the fix and future plans!

Sure it does qualify! Happy Birthday Linda!

This sounds right since R-model frame is a bit narrower than RW2/MH. I have the crossmembers off the R apart sandblasted and painted. So can check out the stampings if needed. Interesting point of using shorter crossmember with spicer plates on the single framed RW/MH. One of my MH's (I have them two) has the very rear beam arranged that way, with spicers at the ends. It's a single frame 1/4" chassis. But it's two stamped shells of the style the original discussion was about, welded together. Also remarkable point is the 2nd MH has the crossbembers off a R/DM. It's Camelback with single 1/4" rails. Sure those parts are wrong for the truck and the rear engine mounts are put on the chassis brackets using spicers to elevate them a bit (for an inch or so). Originally I was surprized seeing the engine lifted up that way but the owner couldn't say anything on that. And later I found the rear of the chassis became narrower than it should so the engine mounts couldn't fit right and somebody in the past arranged the spicers to clear up the edges of the frame rails they would interfere otherwise. Thank you for the part ##.

She's getting looking sexy. That white area - is that plain white color? Or with addition of pearl?

If you look at the #2 photo in the set of pics I posted you may find there was a back to back style using two crossmembers like yours. This way you could make a such one using your old part and that piece of DM. And that would be much stronger than just repair of your original part. But as far as I understand DM must be narrower. Also a berry from the same field - what is 9QL4551M? Is that exactly for Superliner? And for which frame? Single? Or triple?? I ask because those in my R-model are also 9QL-something. I don't keep the digits in my mind and haven't found them in the computer. But those would definitely be different from what you need by the width. At the same time looking almost identical on a picture.

Me either, ha-ha..

It appeared to me the trunnion shaft was higher on Temperleaf than Camelback. Not almost sure, follow Terry's advice.

A five star rating joke!!!

The truck looks having good potential. Congrats!

Looks like Mack used different styles of the crossmembers which played their role equally. Some trucks had the style your truck have, some those flat style doubles. That's for 80's years and maybe earlier. Don't know the reason. Options? Or just supplys from different vendors? My R's are Canadian built (actually assembled) and they look slightly different in a few points than typical US production vehicles. Of what I noted (if I'm not wrong) a certan chassis has all the crossmembers of the same style (what makes sence). But practically it doesn't look any wrong if you put one crossmember of different style and it fits right and functions well.

I wish you guys good luck! Spraying is not very time consuming. When all the prep works are done right.

Worth to point out these do exist of different width. I have two R-models (which are originally differerent to a RW/MH) with those and the truck with double frame has them shorter than the single rail unit. BTW my R-model with Neway has particulary this style for the rearmost crossmember. With shock brackets attached to it.

Looks like ARD-125 to me (the setup in my 1988 R-model) When I was taking my old iron apart a tag was found riveted to the RH (or LH?) airbag support plate down side (seen from the ground).

Check out PAI FKT-4736 and FKT-4737. I've got a trouble with one rod though when PAI bushing was found loosy in the hole. Another rod pressed in Ok. So seems like there could be different vendors of rods with differences in internal specs.

A couple add ons. There's a variation of that cross member as a double style when two similar webs are welded together for more rigidness (the 2nd pic). You can use it too paying attention to the shock brackets (using spicers again or so). And if you find a trouble locating a used part you may contact PG Adams in Vermont. Those folks specialize in fabrication of frame rails for trucks and also offer variety of crossmembers of different styles.

What you have at the rear is a common style Mack chassis crossmember. They were used on many trucks with Camelbacks and other rears in the central portion of the chassis. Just were put upside down overthere. More correctly, the very rear crossmember on your truck put upside down to clear up the trailer pin for coupling (and that's a common practice). Those "common" crossmembers may have holes for the shock brackets. If no you just drill them. There's one point though you need to keep in mind. Frame width is different between RW and earlier Mack model such as R, U, DM, F etc (which used to use those members) Those are narrower so you need a parts from a RW2 (after 1985) or MH Ultraliner (similar chassis). Or you can use a R-model part adding spicer plates. P.S. CH and later models have different distance between the rails too.

Drool, drool, drool!

Outer bearings are 45280/45220 (set 413 as mentioned above) Inners are HM212049/HM212011 (set 409) Stemco seal either 383-0139 or 383-0239. There's a wear ring of 4" OD the seal works against of but you don't need refreshing it if use unified Stemco seals.

Congrats on the purchase! Firetrucks are cook stuff on my mind. I have never had any relation to them myself but definitely would be happy having a classic one in running condition. Maybe some day which hasn't come yet? As for removing the firebody I would keep it in place as was suggested above multiple times. And for transporting the tractor a trailer might be hooked up. Going further this way the tractor might be stylized to fire service too. As Dan Druno made to a R-model in the FAW5371 axle thread, turned out very nice on my mind. Ok, as long as the truck is a red truck with white stripe and the tractor is already a blue tractor with white stripe just a blue trailer would complete the case.

Valve seat? That's not a valve guide. As I was told in a local shop they use liquid nitrogen for cooling seats. And although valve guides, surface grinding and many other jobs are made by guys the seat installation is done by the chief himself.

Paul, I love ya!.. About every other morning after waking up I remember the words of your father said. Of how wierd that would be... and so on. Than after 10 or 15 more minutes I force myself to stand up I would definitely like to have much more energy for the day since I have tons of plans and ideas on turning stuff over or inside out. But unfortunately I'm short on energy and always was from the times I remember myself. Never liked gym excersizes and preferred to tinker with small stuff. Slowly and patiently. This way I just try my best doing every day as much as I can. And also remember your advice on keeping small steps. About every other time I need to kick myself for a few more extra steps Vlad
