Centre exhaust mount bolt sheared

[reetp]

Centre exhaust mount bolt sheared. Damn damn damn.

Having just finished my exploits with an engine mount, whilst hunting for the issue I had noticed that the centre exhaust block was pretty knackered (the square one that supports the centre box and bolts to the chassis) and I decided to change it for a shiny new one. Best laid plans & all that.

Both bolts free OK, but the shafts were clearly clagged, and inevitably the top one sheared as I was removing it. :doh

Sprayed some release stuff on the lower one but decided not to risk removing it in case I buggered that one as well. Tightened it back up for now, but clearly all pretty shaky shaky under there now with one bolt and knackered support.

Any one had a similar experience and have any solutions??

As Rustic taught me undo a bit and then tighten again and keep repeating until the bolt comes out.
As for your other bolt you will probably have to drill it out carefully and retap the hole assuming it’s the two bolts that go into the chassis.
Then when putting bolts back smear some copper slip on them happy days.

Ironic as I have done that a million times and for whatever reason had a brain fart.

They felt ok... but clearly not.

No fun to drill it out as you need the box out of the way :-(

Damn damn damn :-(

I feel some improvisation coming.....

you could always use some self drilling roofing sheets bolts i have done it the past just let it drill in to old bolt

Nice... if I can get a drill in there first.

Wonder what they're called in Spanish??!!

Weld a nut on and wind it out

It's pretty well flush with the chassis rail :-(

When I snapped one of mine, I WD40'd it, then used the Dremil to cut a slot in the remains of the bolt, getting it nice and hot, then used a screw driver bit in my small ratchet set and wound the bolt in, so it then went right through and dropped into the chassis.

That is a brilliant bit of advice, much better than trying to extract a threaded bolt with 10 mm of corrosion on threads that need to come through the captive nut, Rick

Absolutely agree.

I'll be under for a play in the morrow!

Ooohhh errr missus......

It'll need drilling, and that isn't easy to do with the exhaust in place.

Anyways, much quieter with a new mount and just one bolt. Old one let it flap around like the proverbial shithouse door!!
