thanks all, i went to see the rs700l saturday. the good part, its all original, the bad, foor rust, back of cab, pretty much needs restoration. i have learned my lesson on rust so am not interested, anyone else want it? they are asking $4500. maybe worth $2000. ray

hey guys, im going to look at a 1975 RS700L tomorow for sale. 300k. the original owner say twin stick, not sure of engine. says rust on floor and back of cab. what is the difference from say a rd600? was this called a western style? is it collectable?

thanks ray

Hey, Im looking at a 1975 RS700L tomorrow. Was that called western style? Whats different than a Rd or Rs 600? He says company bought it new and has about 300k, A twinstick trans and not sure of motor size. also has rust on floor and behind cab, curently a tractor. Thanks ray

did you get someone to look at it? ray

i want to replace my air ride single axle on my "evil' volvo fe42 tree spade truck with locking spring ride axle. its too mushy and wanders. i tried helpers to no avail. i would like 3.7 ratio.

oh heres another request . today at an auction i bought a 1953 chev 4400 grain truck with 12k miles. all original. does anyone know of a 2 speed rear for it? thanks ray

why split gears? the t2080 has 3 off road gears which i need. so that leaves only 5 for the highway. because such a large gap when shifting especially 7 to 8th. actually the top gear is .6 overdrive. ray

ok thanks brian, is the 1241 made by mack?

hey, dont want to go faster , want to split gears. and dont want to lose off road gears. $5000 for 1241? what is 1241? ignorant cuss i am.

Does anyone have an auxillary transmission for my RD with em7 and t2080 trans? thanks ray

oh, a 4 sp aux is not a quad box. yes a 5sp auto with aux trans would be welcome. jamming gears off road to move inches when digging trees is a pain. ray

thanks for info so far, 5.03 rears runs nice up to 65 mph, thats plenty fast for top heavy tree spade. it needs the 3 low hole speeds off road or simular.

rpm's pulls to 1600-1800 nicely

major drop between road gears, annoying. has .6 overdrive

hmmmm, thats why i ask questions. i drove an r model with 5sp auto and quad box last week that gave me the idea. maybe 13 or 18 speed? how much overdrive do they have? ray

hello all, am looking to add speeds for my em7 with t2080 trans. am green on quad specs. call ray at 612-709-1397

Hey guys, I need advice on getting more speeds for my mack em7 300 hp with 8 speed. It has 5.03 rears. My understanding is that the 2080 trans has 40% OD. I have a 85" tree spade and the 3 low grears work great off road. On road it is basically a 5 speed. I am adding a pod trailer this week and would like more gears or more POWER, haha. Could a quad box help? Thanks Ray

history? miles? repairs needed? cab to axle? thanks ray

Ok, Finally got it off. Kind of sick mack puzzle. I definately need a repair manual to save time and energy. Hopefully I will be able to get the gear in the right place and time the thing, with the secret plug and rotating cog. Ha. The dealer warned me not to do it myself, said I would need an A-B timing light. Oh well a person never learned without mistakes. Thanks again ray

I printed your directions and will try this morning. thanks oh ya 91 300hp. ray

It is a 4 valve em7.

I need to remove my inj pump today. the shop said there is a mark to line up under a cover. Is the the mark under the front pan facing the radiator? thanks ray

I need some advice on my 91 Em7 300 hp. last fall i started losing coolant in my tree spade truck. checked for leaks externally. The pressure gage drops from 10# down to 4 in 2-3 minutes. dealer says liners? Any ideas or suggestions.Repair money limited as large trees seem to bean extravagance in this economy. Thanks Ray

What size tires do you run?

1100-22.5

7.00 rears with 1100X22.5 tires at 70 mph, the drive shaft is turning 4000 rpm.

Ok Guys, What rears should I look for ? keep in mind the trans has a 40% OD. If I could drive comfortable at 65 , I would be happy. Ray

I agree- upshifting on an uphill is the Maxidyne's weak point. Turning the governor up to 2100 or so shouldn't hurt the engine, won't hurt fuel economy unless you cruise it above 1800, and will make for a marvelously flexible engine.

Ok , I found the problem 7.00 gears. So anybody any ideas for an aux transmission to upgrade? Anybody with parts for sale?

I think an MR or an LE would suit you well. I have the ins with a few people and ussually get them for around $10,000 almost always allison 740s (4 speeds). ussually come with big hydraulic pumps crankshaft driven. I'll attatch a before picture of the last one i did. (spent alot of money on body work etc.) I also put a former postal CH together as a TMR truck (also auto 740), That truck turned out good too!!

OK I found the ratio 7.00!!!!!!!!!!!!! No wonder it is slow.
