M3 PINK: Changing it up! Toyota Land Cruiser 2UZ-FE Timing Belt Change

Im about to do mine...very informative, best i found yet.

Only thing we can't do on the 4runner would be using a Impact to remove the crank bolt.

Very nice DIY indeed.

x2!

Thank you for sharing!
Also, it is very pleasant to see another very positive engineering\ design comparison to other car manufacture (German cars in this case) from obvious “hands on” mechanic. And another proof of how reliable timing belt design is in Toyota 4.7 V8….

I didn't use an impact on my crank bolt, just a long cheater on my 3/4-drive socket wrench.

Several writeups on the timing belt here, including mine: 100 series LC/LX FAQ and Featured Trucks

Well damn, this whole time I thought I had a timing chain!

scottm!

coool!

Great photos!

Thanks I've been looking for this even though I have a Hayne's manual. Just in time as I have 88K.

I did mine several weeks ago. I think it was a ***** to get to the a/c compressor bolts jut by the angle of the bolt. and I would say everything else was pretty straight forward. just make sure you have a manual cause it mentions about the teeth position when installing the belt and is very useful and makes a great difference.

I recently put together a very detailed how-to video on changing the timing belt in the LS430, which is very similar. Here's a link, hope you find it helpful!

Was there a reason you could not use an impact wrench?

The OP posted 10 years ago so I doubt that he'll see this and reply but not because it was 10 years ago but because from viewing his profile he hasn't logged in on the forum in 2 years.

I can however answer your question, the reason most don't use an impact is because of the very high torque value that is required for the crank bolt, I don't recall the exact torque value but it's up around 300 ft. lbs. and very few impacts can apply that much torque, at least most normal 1/2" impacts can't, a good 3/4" impact can, but any impact that can apply that much torque are very expensive and require a very high volume/CFM of air which only commercial compressors can deliver.

There are a few very good write ups on the forum for the DYIer that will help you greatly, so search for them which will be worth the effort.

My M18 Milwaukee 1/2” impact is 1100 ft/lb of break torque. Popped the crank bolt off easy.

When I did mine on my 02 Sequoia I pulled everything out, radiator and all. Made plenty of room to work. Impact fit right in.

I also own the M18 1/2" impact but it's one of the exceptions, and not everyone has one and many can't afford one, most DYIers have small battery impacts or normal bargain type 1/2" pneumatic impacts neither of which will come close to removing the crank bolt and most struggle to remove lugnuts.

The poster above was asking “why wouldn’t” one use an impact. Your point about someone not having one powerful enough is not a valid response.

Bottom line, an impact can be used, and the vast majority of us wrench turners use them whenever possible.

I beg to differ, my point was completely valid, I didn't say an impact couldn't be used, if everyone had an impact strong enough to remove the crank bolt then they would use it, it's not your place to judge if my response was valid to his question or not, that would be his decision alone not yours.
