changing belt, need help, think I have a MAJOR problem

[Shinare]

Tried changing my belt today. Got the top bolt loosened and tried loosening the bottom 14mm bolt but it would not budge. So I sprayed a little wd40 and waited, then tried again and stripped the bolt. then I got another 14mm socket that had less points on it and tried with it. Stripped even more. Now I got a pretty much rounded bolt.

what can I do aside from taking it to the dealer and them charging me $200 to replace the belt. (their quote a few weeks ago)

[JayPrimo]

Hmmmm.....They make these sockets called "Turbo Sockets" for rounded off bolts, look like this....

They are specifically for stripped/rounded bolts, and will bite into the rounded bolt head as it turns. You should be able to find some cheapo brand at your local auto parts/tools stores for very little money. Harbor Freight carries them but I don't know if you have that chain in your location. I'd recommend buying the size the bolt is and also one size above, just in case. (ex. if its a 10mm bolt, also buy an 11mm turbo socket)

Don't fret buddy, rounded bolts are no big deal. Stripped bolts, now that's scary territory lol. Just make sure you have a replacement bolt handy before you bother removing it.

Good luck :thumbsup:

[Shinare]

Oh, thats a good point, where am I going to get the exact right bolt to replace it? I guess the dealership and ask for the specific bolt?

I think the bolt you need is item #2 in the picture.

#2: 90105-10075
#3: 90119-08A53

I'm a little worried that the bolt didnt even budge. I mean I put a lot of torque on that thing and it stripped the head. should I put more WD40 on there or some liquid wrench on there? I just dont want to shear off the head or something...

[CTScott]

Mine was bent on Crashy2, so it snapped when I tried to remove it. That actually made it easier, as it snapped where the threads begin, right at the alternator. Then the section with the head attached just pulled out, and I was able to then easily remove the alternator to allow me to drill a hole in the remaining part and use an easy-out to remove it. I replaced it with a grade 8.8 bolt and coated the threads with never-seize.

[Shinare]

LOL wow, thats actually pretty scary to me, heh. I have no idea how I would cope if that happened to me. How did you get in there and drill a hole in the broken bolt? I can hardly get my socket wrench in there with a socket on it. I just hope the liquid wrench helps some.

[junorico24]

You need an extension on your spanner or wrench.This gives you that extra oomph you need to loosen that bolt.

[mr_miles]

Don't buy a replacement from Toyota. They're pre-rounded at the top of where the wrench bites. I rounded mine off and bought a Toyota replacement, then decided it was garbage. I'll try to find it and take a picture of it next to a regular bolt for comparison.

The bolt goes through two through-hole on the engine bracket, so if the bolt breaks the part that remains in the alternator is just in the alternator, so you can simply pull the alternator off to work on it.

This


It will also allow you to gradually apply a significant amount of force to the bolt without having to struggle and potentially letting the socket shift/slip which is usually how these problems start. I use a 15" length of copper pipe.



Did you get it worked out OP?

[Shinare]

I went to harbor freight this weekend and did not find any stripped bolt extractor socket (maybe they were sold out of them?). Since I don't have a replacement bolt for it (getting from dealership today) and its not an emergency, I'm going to see if I can order the bolt extractor sockets online. I did find a 17" breaker bar but I don't know the size of the sockets yet so I didn't buy that. heh Hopefully this will get done eventually... hehe

What you need is to soak the bolt in releasing fluid, not WD40. I use Plus gas. which is excellent but I do not know if it is available in the USA. It will creep along the bolt and loosen the corrosion. Failing that diesel is a good releasing fluid. Use a six point socket and work the fluid in by turning the bolt slightly to and fro.

Take it to any local mechanic and just have the simple job of removing the bolt done.

[junorico24]

What has happened is you didn't apply enough force/torque on it. The socket is moving but the bolt will not budge then you end up stripping it. That's what happened to me. I stripped it as well. I realized i wasn't applying enough force down on it. So I got an extension. I used one of these

because I was kind of :eyebulge::eyebulge: scurred at the time that I stuffed it up.So i just got something I could find. But it worked for me it helped to put down enough force/torque on the bolt.So the socket spun the bolt and not just the socket spinning around the bolt.

[Shinare]

Thanks all, the bolt will arrive on Wednesday (ordered it from toyota dealer) and talked to my father-in-law, he has a mechanic buddy that has the tools to remove the rounded bolt for me (so I don't have to buy just for one use). I'll take it to him and hopefully by this weekend this will all be a distant memory, heh.

I have some "Liquid Wrench" at home. I will put some of that on each day over the course of the week. Hopefully that will work better than the WD40. That way its nice and lubed up for the mechanic guy to twist off.

Most likely what happened was a cheap socket was used.

I had to use a 3 foot braker bar with a 6 point (SnapOn)socket to get mine off.

Exactly, the quality of tools you use can also have an impact. I used a poor mans socket set but with a that tyre

nut loosening thing ma gee! lol it worked but i stripped it without the 4 way tire nut cracker extension. :biggrin:

Guilty as charged. All my tools are "el cheapo" as I MAY use a socket once or twice a year.

I started out with a many pointed socket and when that started to slip I changed to a 6 point 14mm I found under a bunch of other sockets I didn't know I had. It looked pretty cheap as well tho. No brand name even on it heh. Then it started to turn on the head... guess I should have started with the 6 point. Live and learn... heh

I use BPblaster spray everytime I work on my suspension and it works like a charm for removing bolts. By the way all you needed was a high grade bolt at the local hardware store, grade 8 - 10 hardened steel. It would've been cheaper than the dealer price for sure. If you gonna do your own mechanic work you might want to invest in some good quality tools, makes a diffirence.

It's PB Blaster and I freakin love the stuff! Been using it for a decade...it even smells good in my opinion. :biggrin:

Yea whatever you know what I meant. I don't think it smells so good but sure get's bolts loose quick quick

[junorico24]

Also make sure you tighten it up real tight to avoid that ear bustin squeal!

[Shinare]

Got the bolt finally but forgot to ask what to torque it to. Anyone know.

[UberSilver]

It does not matter if you use a socket once or twice a year! If it's cheap(India, China), it will cost you more time then the cost of a fancy socket set.

Don't use Dayco's drive belt. It has a habit of stretching. Stay with Toyota's belt.:wink:

That tends to happend if it's not properly tightened in the first place, like over tensioning the belt. Toyota could have put a tensioner pulley to make things easier on us. :iono:

[Shinare]

Well, bolts out and belt is on!!!!! Thanks to all here tht helped me. I finally broke down and bought the expensive roundedbolt set from pep boys as pictured. It finallybroke loose after many squirtsof liquid wrench and a long cheater bar. (Thought i had broke the bolt or wrench how loud it snapped when it finally broke.) Thans again everyone for the support and ideas that gave me the courage to tackle what i thought was an insurmountable problem.

Ps there was this white powder in the threads of the bolt. Some gift of thread lock from someone previous?
