I am needing to learn what Mech is saying. Just because.. 🍻 also it depends on the box the DM has. a sheppard outside frame pitman had the two screws. inside frame ?? closing in on 74 I was still able to keep up with the youngsters loading hay and shaving on flatbed today after all day of sanding/grinding!! so maybe mind cells are off a little.

THANK YOU for the service manual. two set screws were more common(early) ; the large (5/8th ? allen ) did wake some brain cells, don't remember exact application.

Geoff Weeks Posted 7 hours ago Share Posted 7 hours ago twoset screws I think is the earlest design, I know it is on my two digit Sheppard box from the 60's.

mechohaulic Posted 7 hours ago Share Posted 7 hours ago 14 minutes ago, Geoff Weeks said: Sheppard used three different pitman arm retaining methods, you have to know which of the three you are dealing with. Oldest had no nut and two set screws angled out from the box side of the arm. the next style has a hex nut (allen head) and a star washer/retaining tab behind the nut. The last style has a big hex nut that is split half way through and has a small bolt to "squeeze" the nut so it can't back off thought Bob's DM was a '66 which would make it the two set screw version. can't place the "last style" ;; but that's OK - don't expect to be involved with one.

mowerman Posted 5 hours ago Author Share Posted 5 hours ago It’s around a 3/8 coarse bolt set screw towards the front of the truck as these guys mentioned earlier in the post thier not very difficult to remove… but I’ve had this bucket of bolts for 30 years and trust me fellas I swear this sucker is alive… it fights me every job I do but thus last go around I didn’t have any trouble at all this might sound weird but I’m thinking perhaps the bad karma on this old turkey finally left??????????who knows 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/61/#findComment-574905 Share on other sites More sharing options...
