Crankshaft pulley bolt removal and the harmonic balancer

I'm about to tackle this job my self as my 2.7 started leaking slowly. No dripping just weeping. What kind of metal did you use and do you know the specs of your bolts? I've seen people remove the radiator here did it help? I just got the o- seal, the new Allen wrench screws, and funky shaped cover seal. How many hours in total did it take? I'm really curious as I'll be doing this job in my car port. Thanks

 

The metal for the pulley holder I made was the regular old metal "bar stock" that you buy at lowes in the hardware section. IT is 1/4 inch thick and 1 inch wide and 36 inches long. I am finishing the job today. I'll let you know how long it took and all. It wouldn't have taken long at all but I ordered a new Crankshaft bolt just to be safe, I had to wait till that came in at my Toyota dealership. I too am doing this under my car port in the driveway LOL. One day I'll have a garage . Stay tuned tonight and I'll post it on here. I am presently waiting for the sun to warm the outside temp up before I start the work. It's 30 degrees right now. It should get up around 59 degrees in a few hours then I'll start. You ever hit yourself hand when it's cold when a wrench or ratchet slipped ? That crap hurts !!!!!

 

Ouch that's lousy cold! Florida weather is a little kinder here when working outside. Do you know the grade bolt and sizes you used? I'm also ordering the pulley bolt tomorrow since I worry about how much stress that bolt is under. My oil leak has been on this truck for years so at least it kept the rust of the truck for a while lol. I'm just using autozone belts to replace everything when finished. In the repair manual it states to run a sealant along the inner edge of the cover right? what sealant did you find to use?

 

the guy at the bolt shop said that 193 would break your bolt? ...he should get a new job.

 

I posted how to make this type of tool in the sticky thread Homemade Crankshaft Pulley Tool. The bolts that fit into the pulley were class 10.9, M8 x 1.25. I'm pretty sure the length was 35mm, but you might want to get several lengths and pick which works best. tercel89 can post what length his are and how they worked. I also used some washers under the bolt head and nut.

Here is the post in that thread with some pictures.

I just got through a few hours ago. I had to take out my radiator to get more room to pry out the crankshaft oil seal. That was the hardest part. That damn crankshaft seal. Mine seemed in good shape and I wished I had left the old one in place. I finally got it out. But that tool that I made with Dr.Z's plans worked great ! This was around a 2 hr job considering it took more time to take out the radiator.

 

Cool thanks for your advice! I'm planning to try this while the weather here is still warm. Did you pry of the aluminum cover? I got both seals from LC engineering along with Allen head screw kit did you use Toyota silicone or a generic?

 

When you say cover what do you mean ? The only seal I replaced was the crankshaft seal. I have a 2.7 liter engine.

 

I had the oil pump cover which holds the seal off when I did mine and it still took me over 2 hours to get the seal out! So you did good.

Twotacojuan, here are some pictures from when I took mine off. Notice the 2 pins, one on the right and one on the left, that locate the cover on the oil pump. You can't pry too much on one side. You have to work both sides off evenly. Try to clean the area well before removing the cover.


The seal should bottom out and be flush like this.


Here's mine installed with hex screws. You have to be careful removing the old screws. You don't want to strip them. I lightly tapped a screwdriver bit in, then used my ratchet to unscrew. I had JIS screwdriver bits and picked one that fit nice and snugly.

 

That's exactly what I figured thanks! I have been spraying purple power degreaser a little at a time to get all the nasty gunk off that cover that's been built up over the years. I'm going to lightly tap those screws out one by one with an impact driver I've used for years that's come in handy for projects just like this on my old Rsx. I'll post pics and how long it's taken me from start to finish when I'm done. Dr Z did you use jelly to prime the pump or just turned the pump with a narrow screw driver?

 

I didn't put anything in the pump to prime it and didn't turn it. I don't think I took the pump gears out, but if I did I probably just put oil on them. I may have coated the gasket with oil to hold it in place in the groove before I put the cover back on.

 

this how i held the pulling in place while tightening when i loosened it i just put a pull handle on a 19mm put it on the bolt and laid it on the frame. Went inside truck turned key just for a split sec and let the starter break it loose. Simple and fast didnt evev break a sweat
