I was wondering if anyone knows the motor mount nut size. Ive been trying to install a new motor but there is no way i can torque these to 180+ like fordtechmakuloco says in his video. i have stripped the threads oni my second mount. going to need to replace. does anyone know the bolt size and demisions, i cant find them anywhere online and might need to got the local hardware. any help will be greatly apperciated. the nuts head size is m21. its a vibration reduction connecting nut. my mount is also the type that has the same size studs. 2007 5.4 3v flex 4x4 extended cab

 

180+?

Don't break the bolts trying to torque them to 180

 

I found this exact page as well. the only issue is that my bolts are stripping at or before 110. plus the direction above are incomplete. the drivers side has one bolt that has to be torqued to 258 ft pounds, and fordtechmakuloco says that passenger side should be torqued to 184 ft lbs. after i read this page i was hoping 120 would be it, but like i said, a brand new mount strripped before 110. im going to goto lowes troday of the junk yard to find some new nuts. but im still worried about having the correct torque figures. and help is apperciated.

 

i could follow these directions and locktite it at 95lbs i suppose, anyone got any other ideas?

 

The factory bolts are pretty HD (10.9) hardness and should handle 210 Newton Meters or 154 ft lbs. of torque
Been using a wacky packy on them for years and years and years

 

 

Are you doing just the driver or the passenger as well? The passenger for your 07 should have 2 same size bolts. I believe they are 19mm, but could be wrong off the top of my head. The driver side is a 15/16. You need to use a 1/2 deep socket on the passenger side, and you shouldn't have any problem torqueing those to spec.

The driver side is a little difficult. I would use a standard size 1/2 inch 15/16. Don't use a deep socket or you will slip off. Use a metal pipe or breaker bar for leverage and do the best you can. Coat it with blue loctite and get it as tight as you can. Yes, the required torque is difficult, but if you get it within range, you shouldn't have any problem. Just did both recently.

 

this is from for techmakulocos official 5.4 3v randr swap video. it list passenger side torque values as 184ft lbs. i have even contacted brian to make sure specs were correct and he confirmed that 184 is correct.

 

Maybe 07 is different than 04, but here's what my 04 factory
