Phillips head threads?

[Dale]

Trying to get my water pump off and I've hit a snag with this..

Is there a special tool I can get to get in there to crack this? It's just in a really bad spot to get pressure on it, you can't get a screwdriver in there of the right size, nor a drill with a phillips head bit in there.. is there some kind of thing that will go into a socket with a phillips head bit on it that will do it?

It's done up tight too, I'm scared of stuffing the head on it and having to drill it out!

I've tried an assortment of screwdrivers and phillips drive bits from drills but none can get the pressure on it that's needed.

Bit of a simple question I know.

There is an impact screwdriver which you can get, specifically for loosening thses sort of items, however they tend to be bulky and need room to move, as well as a good striking path due to them being hammered inot the hole

I have one of those little bosch ixo screw drivers, I think that would fit in there and pretty sure you can get an attachment big enough!

they are $70 tho, but oh so handy!

That is a good link which describes what i was talking about.

The impact screwdriver looks good takai, just wondering if i'll be able to get in there to hammer it on good enough.. hmm. Might take a trip around to ripco or somewhere and see if they have anything like that?

Just charged up the cordless drill and tried to get it to crack with that, but it was so tight that it spun the head of the drill off rather than cracking the thread! haha

My other options are looking towards drilling the head of the bolt out, undoing the rest afterwards with vice grips, OR using an ezy out or something like that. I hate it when simple jobs become not so simple!

Squid - if I had $70 to spare at the moment I'd consider it but I'll have to wait till pay day on monday

get a bit that fits the slots perfectly, and then use socket..

Get a correct size bit, Grab it in a pair of small vice grips find a suitable lenght piece of metal to brace against the chassie leg and the end of the bit. Possible get a friend to hold a wrecking bar on the piece of metal to maintain pressure and hopefully rotate anti clockwise. Good luck.

lol.. that looks like it would be really frustrating.. i see what u mean bout being so simple yet so difficult..

the only thing i could think of would be (if it doesnt tear up the thread) get the phillips in there, and then grab somethin like vice grips and get a good grip

theres a word for it.. starts with V i think, but basically u get more lee-way (sp??) because of the distance away the grips will be from the screwdriver.

easier to push than turnin the screwdriver handle

make sure u tell us how u got it off in the end

the word you're looking for is torque innit?
F=N*m so if m is bigger, u get more torque on the thing.

Anyway, i believe Karl had an answer for him in the st162 thread... apparently he can pull the whole thing out without undo'in the philips head screw, then just unscrew it with as much room as he likes. heh. seems obvious now ey?

btw, Dale, ive got a socket set (cheap one) with an attachment for screwdriver heads somewhere, so they are obtainable.

The word is probably leverage, which is essentially torque when using lever arms.

And my socket set came with at least 2 dozen screwdriver bits, in phillips, flathead and Torx bits, all with a 3/8" socket attachment. Only problem with that is the Phillips head is designed to cam out when over torqued, so you're quite likely (if the bit doesn't bite properly) so suddenly slam your hand into a rather solid or sharp bit of the car.

Indeed Karl's answer made it all clear!
I have a few screwdriver heads that go into sockets, but nothing would fit quite right, and even those that were pretty much right I couldn't get the pressure on them I needed to push into the screw (using a socket and bar).

74sLeeka - Once I get around to getting it out again I'll let you all know.. I'm thinking it will be easy knowing I can get the pump out without taking that screw out!

[74sLeeka]

hiro is right.. i think leverage was the word i was meaning to use.. but the word in my head was for different meaning.. totally unrelated..

[mullett]

There's only a few different phillips heads, and they're pretty different. 0point, 1 point, etc. I think yours looks like a 3 point. After that, there's also pozi drive bits, which look similar, but have an extra small notch between the 4 main slots of the drive, and while you can use a standard phillips bit in them, much more driving force can be had with a proper pozi drive...

The solution ended up being a drill
Drilled the head off and pulled what was left of the thread out with vice grips once it was all apart.

Big thanks to Karl (warrior) for his advice from the other thread, got me out of trouble here! And thanks to everyone else. +rep

this is the most enjoyable part of working on cars!






























glad to hear you got it sorted
