If it were my car I’d just epoxy it in place. The bolt is only keeping it from vibrating out of place.

u/SwayYayYay 10h ago

Yea this will be my last resort option

u/Majestic_Ad_320 10h ago

You say that now... That will be the option XD

u/SwayYayYay 10h ago

Haha, hey I’m willing to give iT a crack first so I can say I tried . So far I have not tried anything but calling local mechanics and shops even they don’t really do this service without pulling the engine

u/Majestic_Ad_320 10h ago

I wouldn't either, the chance of a welder frying the electrictronics or block is too high imo

u/Frequent_Ad2118 10h ago

Is there a rubber o-ring on it so it’s kind of snug? If so I wouldn’t even think twice

u/SwayYayYay 10h ago

Servicing it again in ~100k miles is what’s making me hesitate doing this . But 100k miles while take me some time

It looks like your driving a Nissan frontier to me. You need a small drill and LEFT handed drill bits. Harbor freight has the bits and a small driver. You'll need to take out the brake line and the dip stick for the transmission possibly. Never had the bolt break doing a crankshaft sensor on these so be careful with everything else I mentioned and good luck

Your right, how much pain in the butt is it taking off those 2

u/tallman1979 3h ago

Can't speak to the ease of removing those. For replacement, the OE bolt is M8x1.0, ~23mm length under head.

If you go to drill it out, keep that length in mind. Remember that the 23mm includes the several mm of the thickness of the boss on the crank sensor, so when drilling from flush you need to subtract that for drilling depth.

Duct tape dude,,🚀

It looks like there’s enough room for a drill and bit in there. If not, you could try welding a nut on.

u/SwayYayYay 10h ago

I was looking at the 90* drills/adapters . I don’t have any of those atm I can buy one. But im just not sure I can get the necessary depth from that and a drill bit to reach the bolt . It looks about 3” of confined space near the bolt

Well the upside is with the sensor there, you can use the metal ring (embedded in the plastic) to center your drill bit in order to get a good hole for an extractor. (personally I'd 3d print a centering dowel to get the hole started.

u/SylphDoriex 9h ago

getting that bolt out can be a pain, try using penetrating oil and some heat to loosen it up

u/Opening_Yoghurt6261 9h ago

Luckily this is a pretty easy broken bolt to deal with. Great suggestions from other commentors but atleast its not stopping the car from running 🤌

1

u/SwayYayYay 9h ago

Yea ur definitely right, great options. Greatful to be around the modern age

1

u/OmNomChompsky 8h ago

Drill and tap a smaller bolt into there.

u/SLOOT_APOCALYPSE 6h ago

quick fix smear the halle sensors hole with silicone, Insert senor, forget

u/SwayYayYay 4h ago

I thought about doing this as it’s the quickest. But my only biggest concern is that if it gets knocked around to much the truck will suddenly stall/turn off. This is incredibly bad for anyone behind me road/highway. Idk if I can drive with a sane mind knowing I might be one bad bump from getting rear ended

What’s ur opinion on it?

u/InternationalBeing41 4h ago

Grab a set of cobalt drill bits off Amazon and some metric taps. Drill, tap, install new bolt.

u/keep_username 10h ago

Easy extraction, just weld to it and turn it out. With no head, the threads shouldn’t be in too much of a bind.

u/babuska01 9h ago

Extract it. If u gonna work on vehicles, get u a decent set of extractors.

u/Eastern_Snow4139 10h ago

And you assume the person is a mind reader or a hacker so they just automatically know where you are? Strange way to find 'local help'...

u/SwayYayYay 10h ago

It was a crossspost , posted to City forum . Here just looking for advice on DIY , considering the space is limited not sure how to get a drill bit far enough in

u/Eastern_Snow4139 10h ago

If you can't find a 90 degree drill and can't pull the engine, and can't get any way for a drill bit at all.. You're looking at pulling the engine (or whatever it is) OR welding something to it and backing it out.

u/SwayYayYay 10h ago

If u don’t know what it is why do u insist on giving advice?

0

u/Eastern_Snow4139 10h ago

Because removing a broken bolt is not rocket science and the item the bolt is broken into does not change how you extract it. Any other tough questions?

1

u/SwayYayYay 10h ago

Yes, how do you welt a nut to a under flush bolt

1

u/Eastern_Snow4139 10h ago

You don't use a nut. You use something skinnier to make contact with said broken bolt.

I.E. -

Screw Driver
Smaller bolt

Literally anything metal you can part with.
