timing belt question

[hoiskii]

Hi.

I'm going to change my TB/water pump/tensioner/idler...
So, suppose I rent a super-heavy-duty impact wrench and get that bolt holding the harmonic balancer removed. Even more, what if I rent a proper puller from Autozone/ChekerAuto and remove the harmonic balancer pulley. My question is: HOW can I tighten the pulley bolt back to specified 80 ft lbs??? Is there a special tool to do this in the Autozone's pulley puller set? I saw some special pulley holder tool on the internet for just (!!!) $200. Those of you who have successfully changed the TB and put the pulley back (!) , please tell me how did you do this.

Thank you!!!

I've actually asked a same question here:
My Timing belt change (very detailed, pics) Gen 4
Taking a starter off woked for me, but some people suggested using a chain wrench. To take off a crank pulley bolt, "blipping" a starter trick worked for me. You can read a thread and find out more about it.

Thanks. I red these very nice instructions too. But my question is NOT about how to remove the bolt, but it is about how to INSTALL IT BACK!!! ???????

Please tell me how did you tighten the bolt at the very end? Thank you so much!

I had to make a custom pulley holder, not too hard for me as I have a torch and mig welder. But I have wondered why no one has produced an aftermarket holder given all the Camrys out there. You could try to remove the starter and have a helper hold the flywheel with a large screwdriver or pry bar. As for renting an impact gun, I would just try the starter bump method - it worked for me when even my custom holder did not provide enough leverage to break the bolt free. It had not been moved in years and never had anti-sieze on it.

I made a tool that actually works .... is strong enough to hold the pulley while you loosen the center bolt, and also tighten it.
I mentioned it a couple of times in the forum, .... no interest. If you want one, send me a pm.
See link here:

It uses two bolts, a couple of pipe nipples, and some angle iron. The picture is the prototype that I have used. ....

Thank you!
Well, I've got an idea of how to use a rental puller to hold the pulley while tightening the bolt... my idea will only work though if I can get a 1/2" extention rod through the puller's central hole ... I'll see.

to dc_98_cam:
Thanks, I actually saw your great tool and I really want one, but only for one day in 3-4 years. So let me try some simpler solutions first. ... like, for example, screwing a short bolt into one of the pulley's holes and block the pulley from turning by placing a bar between the bolt and ground. Have no idea if it works, did anyone try something that simple?

[dc_98_cam]

You are welcome to try. However, I went through the same trial and error process, and found that you have to have something extremely strong .... If your center bolt has not been removed previously, you might be looking at a torque in the range of 200 ft.-lb., to remove.

[hoiskii]

You are right. That's why I think of an extra heavy duty rental impact wrench or maybe the starter approach at the end to unscrew the bolt.

I've taken a starter off and used a long screw sriver to hold a flywheel gear in place. So crank wheel doesn't move. It was actually very easy but you have to remove a battery and its stand for more space to insert a long screw driver. As matter of fact this may work for loosening a bolt, too.

The starter ...
Sounds that I will need to take half of my car apart.
But you are probably right, a similar trick is in the Haynes manual.
Was it hard to remove the starter and to hold the flywheel?

[renmike]

You can either remove the starter up top or remove the inspection plate below and do the same down there.

This idea has some merit ... maybe you can place the 'reaction bar' between the chassis rail ... on one end, and underneath the short bolt in the pulley hole on the other. However, due to the 'recess' of the pulley flange face, I'm not sure if you have a good angle to work with.

Let us know if it works.

... Also, if you decide to remove the inspection plate underneath the flywheel, you can buy a tool at a parts store ... a fly-wheel 'holder', which will grip the teeth of the flywheel and solve the problem .... Still, several dollars to be spent for this item.

Anyone knows which company is the timing belt OEM for Toyota?

The pulley nut will tighten itself when the engine is run.
