Popular Post 85snowdog Posted March 11 Popular Post Share Posted March 11 (edited) Been gone for a while . For some reason the computer wouldn't let me log in. Tried a week ago and hallelujah ! it let me in . My latest project is a 1972 Loadstar 1800. Its extremely heavy duty , and spec'd like no other loadstar we would see in this part of the world. With the extended frame to the front , 10 stud disk wheels ( factory was 9.00 - 20 ) not what's on it now . And factory auto 6 speed trans . Its only got 38,000 miles on it . It has a 392 gas with 7.17 rears . Im sure it won't be very fast , but moving around the yard it feels like it might pull a house down . I'm actually not sure what I'm going to do with it , other than show it off at the odd show. It's in too good of shape to let it get forgot about and possibly go for scrap. Unfortunately , I don't know any history on it . Im currently working on that . I'm thinking it was from the oil fields from western Canada , or something government . They would be the only ones that could buy a truck spec'd like that . A farmer from my part could not afford a truck like this in 1972. I have a question I'm hoping someone can help with. No one I have spoke with knows what the 3rd peddle is . I'm thinking its some type of retarder. not sure though. I'm hoping someone has had some experience with this trans and can tell me how to operate it properly . The 3rd peddle I'm asking about is circled in the pic. It's connected to a valve body on the side of the trans , very close to the trans cooling lines . Thanks in advance Edited March 11 by 85snowdog added picture 4 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/ Share on other sites More sharing options...
mrsmackpaul Posted March 11 Share Posted March 11 A de accelarator pedal perhaps ? Lots of industrial machines have a de accelarator pedal Set the hand throttle and use the pedal to control revs Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-547981 Share on other sites More sharing options...
tjc transport Posted March 11 Share Posted March 11 it is a trans retarder. when actuated it will downshift the trans for braking effect. 2 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

70mackMB Posted March 12 Share Posted March 12 Nice looking lH. Did that have a pump or winch of some kind on the front of it? .....Hippy 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-547990 Share on other sites More sharing options...
Popular Post RoadwayR Posted March 12 Popular Post Share Posted March 12 That is a strange Loadstar, seldom seen any that 'heavy'. Did see a few with 6V-53 Detroits, but most Loadstars were medium duty. Looks like that truck has an Allison MT-40, some of those transmissions did have a retard pedal. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-547995 Share on other sites More sharing options...
BOBWhite Posted March 12 Share Posted March 12 We have a GMC grain truck with a V6 (non running) and an Allison with that 3rd retarder type petal. Not sure mechanically how it works, does it reverse the pump or lock up the converter for engine braking? Could it even work like the early Cats brake saver? I'm guessing something to do with the oilfield the the extended bumper like that, however many of the old trucks around here with automatics worked as mixer trucks in feed-yards or silage cutter operations. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-547996 Share on other sites More sharing options...
BOBWhite Posted March 12 Share Posted March 12 A quick google search answered my transmission question: https://www.wanderlodgeownersgroup.com/downloads/1965AllisonMTBrochure.pdf Great truck with a great engine, All forged internals! Any idea was the PTO knob on this truck runs/ran? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-547997 Share on other sites More sharing options...
85snowdog Posted March 12 Author Share Posted March 12 Thanks everyone for the replies . I knew the knowledge I needed would be here . I always learn more about my internationals here than on an international forum. 9 hours ago, 70mackMB said: Nice looking lH.

Any idea was the PTO knob on this truck runs/ran? Thanks so much for that link BOBWhite. I've been trying to find something like that. Unfortunately my google searches didn't get me anywhere near something like you shared. Thanks again !! The strait frame right out through the grille to the front appears to have held a big winch. You can see something big was bolted there. It looks like the bumper was out even farther but someone has cut it and moved the bumper back in closer to the grille. Theres also evidence of a large gearbox of some type that was mounted to the frame with a driveshaft going to the front of the truck. Its clear to see the spots where there was once hanger bearings . The PTO control on the dash is for a trans mounted PTO. At the moment it runs a shaft drive hydraulic pump. But its clear that's been added after. I think it originally ran a gearbox of some type .

67RModel Posted March 12 Share Posted March 12 Those frame channels look way bigger than any I have ever seen on a regular loadstar. I always thought they were some of the best styled trucks of the time. That cab and front clip design is timeless. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-548003 Share on other sites More sharing options...

Terry Yes , the frame is like nothing I've seen. Its almost 15 inches deep with a 9 inch frame in behind it . Its double from back to front. 9 inches over the front and rear suspension . The frame rails extend past / through the grill. I haven't been able to find another one like that with google searches . 1 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-548026 Share on other sites More sharing options...
Joey Mack Posted March 12 Share Posted March 12 as I read this thread, the more I really like internationals.. Me and my best friend had scouts back in the mid 80's, and I currently own a 48 KB-7, as you may know.. I am really leaning towards wanting more IH's of any kind.. Thanks for the inspiration..

Jojo My attraction to internationals is because of my father and my very first jobs. I grew up with them . Drove my first Mack in the middle 90's and realized what I had been missing. For reliability , power, and durability I don't think a R model or DM can be beat. I just have a soft spot for my binders . Brings back good memories . 1 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-548028 Share on other sites More sharing options...
Mark T Posted March 12 Share Posted March 12 I wonder if that was one of those trucks with the giant vacuum cleaner on it. I remember seeing those with some kind of hose reel (?) on the front. Truck looks to be in very good shape.

Popular Post BOBWhite Posted March 13 Popular Post Share Posted March 13 International Harvester was the only company that had a line of equipment that could go from the field to the elevator. A Combine to harvest, a tractor and grain cart to take it away and a truck to haul it into town all built by the same company. Loadstars are really the only grain trucks left in this area with hardly any GM or Fords still around. Our 1969 Loadstar only gets used for filling up the drills now but it wasn't too long ago when that was our only means of getting grain to the elevator. Speaking of scouts; Some IH dealers would throw in a scout for free whenever a farmer bought a top on the line combine or 4WD tractor. Now they only leave you with the phone number of the mobile mechanic and that's it! 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-548039 Share on other sites More sharing options...
70mackMB Posted March 13 Share Posted March 13 Well your in luck to buy a new Scout soon! But you may have to carry an extension cord and generator. .....Hippy https://www.motortrend.com/news/electric-scout-off-road-suv-and-pickup-updates-factory-groundbreaking/ Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-548043 Share on other sites More sharing options...

We didn't use it for many years and I don't remember why we parked it. They had a diesel version of them too, my uncle told me that they built the gas motor around the design of the diesel instead of the other way around like the 5.7 Olds.

RoadwayR Posted March 13 Share Posted March 13 Kind of, the GMC V-6 was engineed from the start to be gasoline or diesel. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73953-1972-loadstar-my-love-for-loadstars-continues/#findComment-548052 Share on other sites More sharing options...
