Default 88 Camry: Can't get damper pulley bolt loose....


Its the 4-cyl 3S-FE engine.
I have about run out of ideas. I soaked the pulley and bolt in Seafoam
for days. I did the " screwdriver jammed into the flywheel teeth"
trick to lock the engine. Tried a 1/2 in air impact wrench at 100 PSI
first, that did not work. Then tried a 1/2 in breaker bar with the
impact socket, hitting the bar with a heavy mallet. NO joy. Put
starter back in and tried to break bolt loose by cranking engine, that
didn't work, either. The bolt is starting to get damaged, rounded a
bit... but my 19mm impact socket still holds on it. I can't even get
to first base replacing water pump, oil pump, timing belt, until I can
get that damper pulley off. I am just going to end up ruining the bolt
head, and then will have to drill with sucessively larger bits until
the whole bolt head coms off, I guess. Then I would have the problem
of easy-outing the bolt stud. I also tried some "freeze spray"
(R-134) on the bolt, no help. I have an acetylene torch but that
would likely ruin the pulley, because I think it is two parts held
together in the middle by rubber.
Its not reverse-threaded, so that it has to be turned clockwise, is
it? I didn't try that.
Any other "tricks" I can try before drilling the bolt head off?

Just to make sure, its not a lefthand thread?

You may need to put a 4 ft length of pipe on it and really give it a go.
Check with the group to see if its RHthread.

If the bolt is starting to get damaged it's time to stop.

If the bolt has not been removed, there hasn't been much disassembly.

Just order a new bolt from the dealer, put the car back together, drive
it to a local shop, and let them remove the bolt, temporarily install
your new bolt, and tighten it enough for you to drive home and
continue.

Shouldn't take more than a few minutes and a couple of dollars.

Going to be a major headache for you if you try drilling that hardened
steel bolt.
If the bit slips or you damage the end of the crankshaft, your project
will become much more interesting.

================================================== =========
Next time, try Kroil. Seafoam is for a completely different purpose.

Hitting a breaker bar with a mallet never works. If you need additional
leverage, add a "cheater bar" extension.

Impact wrench or starter motor should have done the job for you. Either
the impact wrench capacity rating is too low, or the starter - battery
is not in optimum condition.

At this point, simply have a professional mechanic who does this on a
daily basis remove the bolt. This is routine for them and you will
avoid the not insubstantial risk of damaging the bolt further. You're
going to be amazed how quickly and easily it comes out with the proper
equipment. Easy, inexpensive and safe. Just turn the car over to them
for that one item and don't sweat it. The objective is to be able to
continue your work.

I did this once with a mangled sway bar end link bolt which I
"inherited" with the car. Could barely get a wrench on it, much less
loosen it. Local garage had it off in seconds, and my neighbor had a
similar experience with an axle nut, after destroying a 1/2" breaker
bar with still no effect on that axle nut, they had removed in less
than a minute it like it was nothing.

For future reference, when you say you "put the starter back in" - you
don't need to take the starter out.
If you want to use the flywheel teeth to hold the engine from turning,
you access them by removing the sitffener plate at the botom of the
engine near the transaxle. You should see a small, light, sheet metal
section that is held in by a few bolts to reveal the flywheel.
I've never used that method, though.

That bolt is only supposed to be torqued to 80 ft. lbs., like a lug nut
on the wheels.

It should not take you much more than the force needed to remove a
wheel lug nut. If so, STOP and let a shop do this for a few dollars as
recommended earlier.

The trick is to be able to hold the crank pulley. I use own tool made
of 2x4 lumber and grade 5 bolts that goes through the pulley spokes
(not the drilled bolt holes). If it takes any more than what you need
on a wheel lug, then it's likely to have seized up after all these
years.

Well, its not a reverse-threaded bolt, is it? The Haynes manual
ddoesn't say that it is.

I had a similar problem with a '86 Camry. I need the help of my son. We
used the pry bar method between a steel tight fitted pin into the
pulley and the socket head. I believe the other end of the pry bar was
held by the driveway. My son kept his foot against the socket and pry
bar to keep them from falling off.

THE BOLT IS A STANDARD RIHGT HAND THREAD.

Good Luck.

You can safely assume its RH thread in that case.

Locking the flywheel properly is the key. Some people use a "U" shaped piece
of tough steel to engage and hold 2 flywheel teeth. As Dan said, descretion
is the better part of valour in some cases ie get a shop to undo it.

On all the engines which had pulley bolts, I used to use a large straight
bladed screwdriver to engage the flywheel teeth or in some cases a hole in
the torque-convertor driveplate to hold the crank. Mechanical shops probably
have better ideas tho.

I had the same problem with my 94 V6. 1/2 inch impact wouldn't budge it.
Rented a 3/4, using the same 100psi and it poped it right out. They use some
type of locktite during assembly which works really well.

Different 1/2 inch guns have different abilities-- how much did it cost the
user? every once in a while I get one that no 1/2 inch gun in out shop will
budge; I bring out BIG BERTHA, a 3/4 inch gun. She has only struggled once
but she has always won.
