Hello, I am new to this forum, so thanks for having me aboard.
I am in the process of taking out the crankshaft while leaving the rest of the engine alone, so that I can get it to the machine shop to see if it is salvagable after a spun rod bearing.
Like the title says I am at a dead stop at this crankshaft sprocket (hooks up with the timing belt). The manual says to use two flat head screw drives simultaniously, but this is not working. I have also tried to hit it up with some wd-40 and nada. IT IS IN THERE!!!
Is there any tools that ya'll no of. Or any other product other than WD-40. Or anything at all would help.
It is a 3vze 3.0.

 

i used a gear puller. came off fine

 

I used 2 big screwdrivers on mine, it eventualy came off. I couldn't find a puller that would fit.

 

LTrunner, do you remember where you got that puller from did you rent it from a parts store or did you buy it? I'll go to autozone and see if i can get creative with one of there rental tools.

 

You can get a decent 3 prong gear pulley from sears for pretty cheap...

 

Okay, thanks guys. I found a three prong pulley tool for rent at advance auto parts that looks as if it'll do the job.
By the way, do you think that a How-To-Thread on pulling the crankshaft would be something worth of interest on this site?

 

 

Steering wheel puller works great for it. Take off the front part of the pulley(4 bolts on the front). And there should be 2 bolts in the steering wheel puller kit that will screw right into 2 of the 4 bolt holes.

Pulls off like a charm. Normally Toyota pulleys come off by hand but sometimes corrosion holds them on a bit.

 

Careful -- the sprocket has a Woodruff key (sort-of semi-circular). The rounded side is toward the crankshaft. If it sticks every-so-slightly to the sprocket, as you move the sprocket the key will rotate up in the crankshaft jamming against sprocket. If that happens you could pick up the whole truck by the sprocket; it won't come loose.

VERY gently tap the key back in. If it moved, that will move it back, and it will rotate back to flat as it goes. If it hadn't moved, you may rotate it very slightly in the other direction, but that doesn't matter. As you pull on the sprocket it will push it back against the crankshaft.

 

^Very possible but also very unlikely i've never seen that happen before. Odds of that are low but something to think about.

 

i got the pulley off with ease, its the sprocket i cant get off

this seems realistic, i just thought that key fits in there to snug to move at all. i will try this though. i get exactly what your talking about.i tryed tapping the sprocket inward just to mayby break it from its sticking point ever so slightly.

 

I used two flat heads... came right out... try doing it in a way you can keep it straight on the key way...

 

well. i got it off. but not without sweating some damge i have done. first off. this thing was seized for sure. screwdriver thing was a joke.

after i got it off last night i seen a post on youtube that some drill and tap two opposing holes on the sprocket face. insert bolts and use them for the puller. well that was to late. then i didnt realize gear pullers have very flat tabs on the end i could of used to get behind the sprocket. my cousin has one that he said would have been skinny enough to get behind it from the start. too late as well.

heres the damage

now i know there are micro sleaves that can be used on the rear seal and think i remember them being used on the front as well. the seal running a seam in the crank. can one be used here and where do i find these at?
i almost sits on the outside of the seal but def lays under the seal on most of the gouge. i dont wann take any chances and put it back together buy just throwing another seal on there.

im bummed. please help

 

Ooo... >_<

Thats no good...

Normally this should be avoided... unless the seal was leaking or the oil pump was leaking or faulty... i prob would have left it alone...

I've seen a few crankshaft repair sleeves before for the acctual shaft itself.... but most of them were installed on the crank with the crankshaft removed from the engine.... >_<

You could try and look online and buy one and try it... you will need a special driver(Tool) to install...

But they do sell em... tis your only option... or replace crankshaft...

 

I have priced them out. I beleive rockauto has them for about 5$ and the tool is like 22$. I decided to do this because I had the engine out and I'm replacing everything before I put it back in. Just didn't plan on this happening and it got me very upset. Would just like to hear where otheres have gotten theres and the opinions they have on them .

 

I used a impact gun . Think I nearly took the whole engine apart, using a impact ratchet and gun. That's in the dark,with a flash light while it's still mounted to the mounts.

 

Pulley became very wobbly loose. PS, AC Compressor, Alternator belts almost fell off. Removed pulley Bolt easily. Woodruff key kooks gnarled, can't figure out what to do with it. Can not remove sprocket by hand. HELP. How do I remove sprocket so I can replace the key, then the sprocket, then the pulley etc.? Is this type key readily available at say Advance Auto or Auto Zone? Thanks anyone.

 

DYIJack, what engine, year etc. are you working on?
Toyota dealer has been my source for the keys. Can't say I've ever tried the local parts store for them.
Does your crank pulley have the threaded holes already tapped into it?

 

The woodruff key is the common half-moon type. Sometimes, when pulling on the Harmonic balancer, the key starts to slide out. It moves up the "ramp" in the crankshaft and jams against the HB; pulling just makes it tighter. You MIGHT be able to gently tap the key back in, and then the HB should slide off easily.

Should. If you've gnarled the woodruff key, you may have gnarled the end of the crankshaft. I have no idea how to repair that, other than replace the crank.

Good luck!
