Motor mount bracket ?

Well ... Looks like the motor mount bracket has separated from the weld on the frame . The bracket May be able to be salvaged but I was wondering if anyone knows where I can find a bracket ? 1975 scoutii with a 345 and manual trans as u can see in the photo the bracket sits about 3" lower than the weld that broke .

Same thing happened to my '74 about 20 yrs ago. Did your fan shred your radiator shroud?
I just jacked it back into position and welded it up. Been like that ever since. I'm sure your bracket is fine. Just clean all the gunk around the original weld and have someone burn it back in.
 
I can weld it up ... Just worried about structural integrity . But if you say it'll be fine then ok. I found a bracket through a member of the forum . Just in case but with holidays approaching fast , Scout finances are on halt
 
This injury happens because of the manual trans. It has to do with the way IH arranged the clutch pedal actuation. When the clutch is feathered out (especially on a hill), the engine naturally twists against the motor mounts. Since the clutch linkage is vertical, the twisting of the motor actually decreases slightly more clutch than you want (its pulling up on the clutch rod). Then the load on the clutch decreases, and begins to bite again, only to twist the motor again, and unload the clutch releasing it again. Its this on-again-off-again application of clutch (chatter) that hammers that motor mount.
Other makes of trucks have horizontal actuation of the forks and are less affected by this phenomenon.
Nothing wrong with the straightsteer, but it won't solve this problem. It will keep the motor off the ground though.
 
So .... Should I run some extra beads? Cuz it looks like there was only one horizontal bead on top of the bracket . Nothing on the vertical braces . But truth be told it looks as though who ever welded it didn't have a strong enough welder . Only the frame bead got actual metal penetration
 
Mine was that way too. Makes me wonder how it held for the first 20 yrs...
I just put some quality welds on the vertical parts of the bracket. No problem since.
Gotta figure there were plenty of drunk/hungover/high/tweakers/downers that were "welders" on that line. My spring mounts, shock mounts, (basically anything welded to the frame) were sketchy. I ran beads over anything that didn't look right.
