my motor mount broke on my single cam ZC
i tried a left handed drill but it didnt work. what else can i do!!?

i was able to get the bolt (cicled in blue) out cuz part of it was sticking out. The other bolt (circled in red) broke at the very end so i was unable to get a hold of it.

tried a left handed drill. got about a quarter inch deep. wouldnt budge.

 

bump

 

night bump

 

extractor, drill and tap, reverse bit, small amounts of heat might work but thats also pretty risky on the block. soak the lower one with oil and work it back and forth. good luck

 

Just like he said. Use an extractor make sure to use the biggest one possible and dont ever use just the tip of the extractor make sure you let it embed itself deep into the bolt you are extracting so that it wont break off in there when you go to remove it. Use some PB blaster as well and drill bloody straight and slow.

 

nothing is going to hepl unless u goto a bigger extracter and drill dead straight, if not, thats like pulling a car crooked out of a garage, doenst work.Use lube, never too much lube, never ever.lol.

A good friend blew his low comp. GSR due to that mount breaking and it breaking the T belt.

 

drill right through the bolt with a drill, then use an easy out. or you could try a punch and hammer, but it sounds like it is too tight for that method. essentially, you try to spin it out by digging the punch into one edge/side of the bolt and hammer away. i've used this method many times with success on industrial applications, but automotive applications it is often more difficult.

 

get a new block. if you btoke it with a rachet the extractor is just gonna break in the bolt. time for a b series

extractors seem to very rarely work for situations like those. is there enough room to weld another bolt to it? thats saved my *** numerous times. i dont even waste my time with extractors anymore.

 

i agree with joe
the more ive tried extractors the more they seem to get me in trouble
welding is an option
or completely drill out, oversized rethread with thread repair kit

thats ur options
or take to machine shop and pay someone to do it
hope this helps

You can just drill it the exact size or one size under and tap it but make sure your square and even when you drill and tap it so you will not run into any problems after....

If that doesnt work oversize drilling it and use a thread repair kit like stated they have worked well in the past with no problems....

Good luck with it ...

 

so i shouldnt use a screw extractor?

 

oh yea...the bolt was torqued down pretty good before it snapped so what method would be better since it was torqued down?

 

get a new block??? are you insane?

screw trying to pick it out.
just drill it. use a smaller drill bit that will ONLY drill the center of the steel bolt. then step up to a larger bit. trying to do it all with a large bit will be harder, and cause a real wobbly hole/out of round. do it in smaller bits, and work your way up to a larger bit. keep an eye on the shavings. stop when its all aluminum.

tap it, and use an insert like helicoil, and lube your thread with antiseize so it doesnt happen again!

buy a new block....better yet, just get a new car. i mean have you considered suicide??? then you dont have to worry about it at all.....

 

you have no idea what to do... if it was me.

I would take a nut, with the center the exact size of the bolt that broke, lay it over top of the broken bolt, and weld the center of the nut full welding it to the piece in the block, you need to get really good penetration or else it wont hold, then just loosen the nut. Goodluck.

pay someone to do it or buy a new block. dont use an extractor, if the bolt broke in the first place the extractor will just break as well, extractors are junk IMO.

 

cut a slit in it w/a dremel and use an impact screw driver.

 

The craftsman bolt outs can be a pain if you don't use it right it makes it worst.

Drill straight through it and weaken it's tension on the female threads in the block and get a reverse threaded drill bit that fits tightly .

 

sell it to one of us who can weld for 5 bucks...........we will fix the block in less than 5 mins and sell it back on here to people that can't do much

we will really apperciate the profit

I've had good luck using this method and if it were my block, this is what I'd do.

If you do decide to keep drilling, your gonna need a better drill. Something that you can slow down the speed and still have lots of tourqe.

 

jerry tap & drill ... i believe they are in anaheim... im if you need number

Thats your best bet. I always TIG a washer to the bolt first, then a nut to that. It's a lot easier to penetrate the broken bolt when you can see it...although I bet if you used a MIG and just set it to stun it would work too.

 

it'd be so sweet if my mig had a stun setting...i could use it like a star trek taser

 

Like others said just weld another bolt to it. I did this on my brother's head recently and it was amazing how easy the bolt comes out then.

I think the heat has alot to do with it. I did this recently and by the time i finished welding i could remove it with my hands

 

I think you are exactly right. If the heat doesn't loosen it up to where you can take it out with your hands, you have that nice new bolt head on there to help. Definitely the only way to get out a steel bolt.
