oops, jjust realized i put this in the wrong place. sorry

picked up an 84 superliner a few weeks ago. it is an rws721lst. here is what i know. em9 400hp, maxitorque 12 speed. mack axles(44k), canadian spread with hendrickson walking beam setup.steering box mounted in the front axle( doesnt turn good at all) power divider lock switch on dash (doesn't seem to make a difference) the truck began life as a tractor and was converted to a dump truck in Canada in 87(speedo in km/h) it now has a 16 foot dump box and it was restored in the late 90s early 2000s. somethings were changed around and swapped out. it has been converted to the rectangular head lights, the mack heated mirrors were takin off. the heat, and I think ac unit is MIA, the whole thing. the intercooler pipes are not correct and are rigged up. it had a drop axle at 1 point,still has the control in the cab. so what I'm wondering is what does the rsw721lst actually stand for? did this truck actually have AC from the factory( the condenser grill is there). also why does the turning radius suck so bad on this thing, I used it for hauling corn silage, I was having a hard time even in the fields, but maybe I'm just used to my old 6 wheeler IH. there are some parts that I am looking for too. the chrome/ aluminum trim piece on the pass side of the grill is missing, and the plastic piece on the ceiling of the cab where the radio goes is all busted up so looking for 1 of those. thanks

thank you for clearing that up.

Hi all. Im Nick from New York. Im will be 25 in about a week. I am a graduate of the diesel tech program at Suny Morrisville. I have been a truck lover since I can remember and a mack lover for a long time. I grew up on a 600 acre farm and still work there. we borrowed a 84 r model tandem axle tractor for a while. it had a 237 with a 5+2. was a fun truck and the first tractor trailer I drove. we had a flat deck for hauling hay and a dump trailer for hauling silage. when we were no longer able to borrow it I pieced together a 79 ih s1724 that I bought for about scrap price. junked the big block that was in it and installed my dt360 that I had bought for a pulling truck that never got built. fast forward to last fall. I rolled it over on the silage pack and destroyed the lift cylinders and badly tween the converted dumping stake body. after that happened I borrowed a 87 dm mack with a 300+ and 9spd. 58k rears and a drop axle. that was a really nice truck and was for sale but the guy wanted 10k for it and I knew that I couldn't afford it at the time really(my girlfriends uncle ended up buying it). But I always had my eye on the super liner that the retired excavation guy had down the road. he has been long time friends with my father. I finally asked to look at it the other day and that is why I am here now. it is an 84, has an em9 400hp. 12spd maxitorque trans. spread rear axles, with camel back springs and walking beams. Dayton wheels all around. very nice ~16ft dump body that is setup to be heated( ill never need it to be). at 1 point it had a lift axle. shows 384xxx miles and about 6k hours if I remember right. interior is ok, but driver seat shot.( I have a good used 1)I mad the guy an offer and he didn't say no. the truck has not been on the road since 2010 and hasn't moved in about 2 years. I went back yesterday and rolled the hood again. it has the v style injection pump, which I though it should have the inline p-pump. it does have the charge air cooler. exhaust is rotted. is there anything else I should look for? he says he had to put a new cam in it. do these motors have any serious problems? I usually don't post much but do a lot of reading and browsing. I do try to put in my input sometimes though to help out. this looks to be a great site. THANK YOU
