Quickfarms Posted October 5, 2022 Share Posted October 5, 2022 Can anyone identify this 4 spring suspension? it is on a 1972 RS700 that I believe is a glider 1 Quote Link to comment Share on other sites More sharing options...
Mark T Posted October 5, 2022 Share Posted October 5, 2022 I'm not sure what suspension that is, but that's a nice old truck. Looks like it has a Detroit ? 1 Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted October 6, 2022 Share Posted October 6, 2022 don't recall such a light equalizer being on a tractor. if I'm seeing right ,the rear drive has the parking brake cans with one disconnected. a little T L C that would make a real nice truck . R700 western ,old kysor AC and bullet roof lights . Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted October 6, 2022 Share Posted October 6, 2022 must have been parked for some time based on the cob webs. a real great barn find. see the sangangomo (wrong spelling) speedo /clock on the dash; haven't seen one of those since the '70's. I still have quite a few DD tools in my toolbox. just a suggestion, I would clean off the top half of engine and remove the valve covers to make sure the rack and injector plungers move freely. a runaway DD is a scary and costly situation. you would be sick if I told you all the brand new DD parts I threw over the bank yrs ago. turbo's, new complete piston kits , and the list goes on. got tired of moving them around my garage. 1 Quote Link to comment Share on other sites More sharing options...

Last registered in 1993, used as a yard mule until 8 years ago. No brakes on the front axle and only spring brakes on the rear most axle, the disconnected air can probably leaks much worse than the one that is still connected. once it is running I will replace, or rebuild, all the air cans and see if that starts to correct the air loss issue tell me more about checking the rack and injector plungers Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted October 6, 2022 Share Posted October 6, 2022 I thought it was from an international with Eaton rears, and the aluminum rims are modern,, didnt see if they were budd's or hub piloted.. i'll look again.. The truck is still cool.. but I think its a Mongrel... sorry, dont know how to spell Mongrel..... jojo 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted October 7, 2022 Share Posted October 7, 2022 looks like budd wheels on the front, i assume budd's on the rear,,, certainly not spokes with aluminum rims.. I would be curious if there is a seem where it was married to a back half? Its a cool truck... Just my 2 cent's... Jojo 2 Quote Link to comment Share on other sites More sharing options...

Jojo most gliders were long frame rails with suspension added based on wheelbase wanted. cut offs welded to cab front half didn't seem to majority that i remember.

LOL short version which i believe i told before on the forums;; working night shift waterbury Mack CT . a K100 towed in for drive line problems. sat for two weeks in shop waiting for tab to be paid. guy comes in late night ,climbs up in cab . hits the key; engine went beyond wide open in seconds. i rip rear cab engine screen off . CLIMB /CRAWL on top of screaming engine manually flip emergency stop;; tooo late. it shuts down; jack cab remove valve covers :: ALL rockers were shattered. 2 Quote Link to comment Share on other sites More sharing options...

I would remove truck fuel linkage from governor making sure engine linkage is free. enlarging the picture the emergency shut off might not be connected. most of the time , steel cable cuts through the flip lever. MAKE SURE THE EMERGENCY STOP WORKS . sounds like a technical deal ;; it's not;; very simple preventative maintenance. 1 Quote Link to comment Share on other sites More sharing options...

The cable is not connected to the flip lever, it looks like it was just bent over the lever. That seems like a weak way to attach it, how much force would be in the flip lever? The lever moves freely, do I need to check it further? how many batteries should I put in the truck? Here in Southern California i have only run 2 batteries in my other trucks. Will 2 work or do I need 4? Quote Link to comment Share on other sites More sharing options...

The Sangamo Tachograph looks like it should be mounted in the dash to the right of the tachometer. But where it is now was a common spot for them. My MB had one mounted on a 1" X ? length of pipe wielded to plate steel on the dog house. Speedometer cable came thru a hole near the shifter tower. Have two of them, should mount one of 'em where it once was. .....Hippy 1 Quote Link to comment Share on other sites More sharing options...
Mark T Posted October 7, 2022 Share Posted October 7, 2022 Looking at this truck on a laptop. Looks like it has some kind of shifter relocating shift tower ? I'm assuming it's a thirteen speed ???? Looks to be in really nice shape too. Quote Link to comment Share on other sites More sharing options...

Probably doesn't weigh much either. 2 Quote Link to comment Share on other sites More sharing options...
