In the process of a timing belt job and I am stuck. I cannot get the timing belt drive pulley off of the crankshaft (the one that looks like a gear). Any tips? I tried the two screwdriver method which cracked the back of the pulley. I have PB blaster on it now, I also used a MAPP gas torch for a little while (did not get it too hot). Any tips or special tools I should try? I don't think a standard puller will work.

Spend $15 at autozone & get a pulley puller.

I will take a look at NAPA today, in my mind it seems too tight to get the jaws in there.

You are looking for a bolt puller set like this without jaws (assuming your gear has threaded holes in it, some do and some do not):

Reblast it and try tapping on the shaft with hammer and heavy punch. If no center dimple on the shaft, leave the nut on the end of threads.

probably corroded in place.

we were able to do the pry-thing. need more hands than just 2 though. held some blocks of wood in place to pry against rather than prying against the oil pump.

for other pulleys, I have used my favorite tool....webbing. wrap it around and pull VERY tight each time, this will walk the pulley off...or at least, this method had worked for me.

Whew, got it, I almost gave up. I bought a cheap puller for O'reily's like this: http://trackdogracing.com/website/pr...tos/puller.jpg
I ground down the end tangs to fit behind the sprocket. The puller started to bend, so I put the heat on it one more time and it finally gave up, man that made me happy.

Thanks for the tips!

Ah, you guys are wimps. I just use my teeth. Get a couple guys to turn me 'round and 'round by me feet and pops right off!

I tried the starter method, but I wound up on the other side of the shop. That was fun...

I use my buddies teeth to save mine....LOL Not really....I use a mechanical puller of some sort.

SkiRig, how much rust was in there or was something else hanging it up?

<<<ehem>>> ^^^^ whimp....

SkiRig

Yup, it was pretty rusted. Will put a little anti-seize on there this time. The previous owner had the dealer do the timing belt only, no seals, so they probably did not take off the drive sprocket.

Just to be clear, I am talking about the timing belt sprocket that looks like a gear, it drives the timing belt. Not the larger crankshaft pulley that drives the accessory belts (I used a harmonic balancer puller for that, worked great). The timing belt sprocket does not have any tapped holes in it, that is why it is hard to get off. Looks like: http://ww2.justanswer.com/uploads/wo...8_064435_1.jpg

Oh, right. My bad. I just use my toes for that....

Yeah, I knew that is what you were having trouble with. On the 5VZ-FE the timing belt crank gear comes with two holes drilled and tapped. Recently a guy on here hand drilled and tapped holes in a rusted one like yours off to get it off.

Heat with tension/torque is a great thing for removing stuck parts/fasteners.

Belt is back on, only took me 3 times to get the timing right Spring clamps proved useful to clamp the belt to the cam sprockets during initial alignment. Might just get this thing back together tomorrow.

A nifty trcik that I use too....I call them my third and fourth hands.
