Can anyone tell me where # 873AX33F door glass seal goes?

Main is in the middle. But deep is up next to accelerator.

I have a 12 speed with the second gear shift (not on air). It is gated so it can only be used in 1st gear as it should.... The question is, can this be worked around so that shifting through all five gears in the main transmission is possible?

Because they're better, or just the availability ?

The truck is new to me, I have no real first hand knowledge about how it was driven or what it hauled. But when I pulled drain plug found metal (fingernail size pieces). The gear set in it was pitting, flaking, chipping: it was a matter of time. I began to hunt around for a replacement 3.87 crdp92 and nobody had one within a 100 miles.... I actually had a guy tell me he had remanned 3.86 to sell, and that I could just use that... small difference he said. Another guy said he was crazy, totally different .. Which led me to wonder why Mack offered such similar ratios... Then a guy on facebook replied: "I'm sure someone will correct me but from my understanding 3.87 was a weak gear set, most notably the spur gear. Subtle changes were made to make it stronger and the set wound up being 3.86. 4.17 and 3.86 use the same spur gear and 3.87 and 3.65 share the same spur gear, the last 2 being weaker." My rebuilding shop agreed with the above statement at least as far as the "weak gear set" comment. Any truth to this?? I haven't a clue. He can order new parts to rebuild my crdp92 as a 3.87.. total cost around $2000.+ I found a set of carriers with 4.17's in them used for $500..

What's your 'go-to' for an E9 12 speed OD with 11r24.5's in a road tractor? It currently has 3.87's, but I've never worked it... yet. Found metal on drain plug on the crdp92, so I pulled it... gear set is toast. Rebuilder is shying away from replacing the 3.87 ratio. He called it a "weak gear set". I have zero experience with that sort of thing. He's steering me towards 4.42 or 4.17. That's the reason I asked about the closeness of the 3.86-3.87. .. and why he calls it a "weak gear set".

Can you speak as to why two such similar ratios were offered?

He scrapped it.

I need to replace the boot on my 12 speed. It was and has been shot as long as I've owned it. Is there a slick way to fit all those air lines through a boot? I haven't had any success finding a boot through Mack that would fit my early Superliner with the 5"x7" opening. Love to see or hear what others do. Thanks

Has anyone ever seen anything like this before? Is it a retrofit, or some option to get away from the axle mount steering gear? The frame on a Superliner 1 gets pretty narrow (weak?) where this box is mounted. Looks like the original Sheppard gear minus the sub-assembly... very interesting. https://www.purplewave.com/auction/241121A/item/EH2873/1980-MACK-RWS766LST-Trucks-Truck_Tractor-Iowa

I like the stripes. Did the truck stay in Canada?

Yeah!? How about that? Very interesting. I’ve never studied on a 865/6 V8 engine mounting to see how it compares to the E9, perhaps it would fit?

Does anyone know what the production numbers on the all aluminum F model cabs was? Did a “FL700L” indicate aluminum cab as well as frame rails?

You may be thinking of the early V8, the 864(?). I believe it was available in twin turbo form. But I'm fairly certain the E9 was a single turbo only engine for Mack truck operation.

My Superliner 1 has heated mirrors, but they are pretty ugly, glass too, but the elements are still good and work Is it possible to swap over the elements(etc) into non-heated mirrors? Found a beautiful set, but they aren't heated.. Don't have access to any to compare in my hands (I'm talking about the bulldog mirrors) Thanks

F16's on American roads would have caused quite a stir. Joining in the fun of BIG power in the USA at that time.

Driven responsibly, does that set-up return reasonable fuel mileage?

No.. He scrapped it. I was just there last week.. It was pretty rough, would have taken quite a lot to get roadworthy... but the hood was good. No title and wanted $2500.

Fuel tanks straps or steps?

I tried to buy that Road Boss at least ten years ago. Guy that owned it was a contractor for fedex. Had all kinds of old iron. Farm equipment etc. I don’t think he really wanted to sell it even though it was advertised .. more like someone was onhis neck to let stuff go. Something was the matter with the clutch, truck wouldn’t move

Thanks Vlad.

I'd like to find a few of those original lug nut covers.. anybody have some?

Anybody know if this was an option on Superliners? Or was this a one-off? Anybody have any other images of this paint job? Thanks

(Asking for friend in Holland, not my truck) Looking for confirmation on the installation procedure for the thermostat install on E9. Bulletin shows installation tool, and has note on the bottom.. does the sleeve come out with the tool? Or Does it stay with teflon? Friend says it's not closing after opening.

Hoping someone can provide a higher definition image of these SUuperliner designs... anyone? Anyone? Anyone??
