Default Help! Sheared front gearbox carrier bolt.

Any help would greatly be appreciated. Whilst installing gearbox into refurbíd chassis, Iíve managed to shear the bolt that is welded into the chassis tube , that the front gearbox carrier mount attaches to.

Any advice on how I could rectify the problem. Can it be drilled out and replaced? Stuck now as canít continue my chassis build until I can secure the gearbox mount fully.

Thanks

from what i can see. Remove the g/box mount for easier access. Drill out the broken bolt too just under the thread size of the bolt. Then using an easy-out or similar torqbit try to remove
the broken stud. make sure you use plenty of lube wd40 etc.
Iftht fails drill to close to the size and retap the tread

Cut another bolt down, crank up the heat and weld on where it's snapped as it'll be below where you need the thread

The bolt is welded into the chassis, an Easy out won't work as there is no stud there to remove, it's not just threaded in.

Also worth getting a torque wrench too, sometimes these old studs just sheer but at least if you use a torque wrench you know its CORRECT in your mind and less chance of it happening again i love mine.

Sorry, disagree, unless your torque wrench has been checked and calibrated recently, most torque wrenches are way out, even quality ones used in industry. I never trust them.

The only three values you need on a Bug are nipped, just tight enough and 'kin tight

hmmmm fair enough.

i have a halfords one, comes with a calibration certificate, i also check my regularly on calibrated machines at work and its always been spot on.....
i was pleasantly surprised.

i think what harms them is when people use them as breaker bars.

also quality ones used in industry should be regularly calibrated anyways.... and checked before each use. thats our policy at work....
