mason Posted April 21, 2020 Share Posted April 21, 2020 Hello friends, I am trying to change my timing belt and I have a few questions that I need to ask you . The first question is with regard to loosening of the crankshaft pulley bolt . There is a video on YouTube on timing belt for 4Runner 93 . The guy uses the starter to loosen the bolt. The manual says remove the starter and use a pry bar to hold the crankshaft from turning and then you can undo the bolt . Do I have to torque it to 180 pound or just an impact wrench is enough. Your suggestions are greatly appreciated. . Quote Link to comment Share on other sites More sharing options...

You can torque it to 180 but it is extremely unlikely they it will come loose if you get it good and tight Quote Link to comment Share on other sites More sharing options...

Facing the engine it turns clockwise so prop your tools against the drive side. You may want to pull the coil wire it's no big deal if it starts the whole mess will just fall on the floor but it's worth the effort. It may take a couple of hits so don't get discouraged. An impact is more than sufficient. Quote Link to comment Share on other sites More sharing options...

jjrbus Posted April 22, 2020 Share Posted April 22, 2020 I made a simple tool out of a piece of bed frame, for torquing after installation. Quote Link to comment Share on other sites More sharing options...

Well being a grease monkey and shop owner for 38 years it "was tight enough" never had one fall off! There are certain things that torque is extremely important that's not one of them. I gather you have an impact gun that should be sufficient. If not you'll need to block the flywheel or the crankshaft. You sure it's 180 FP that's a good bit of torque.

mason Posted April 22, 2020 Author Share Posted April 22, 2020 Yes I should be able to borrow an impact wrench. Thanks for the responses. Quote Link to comment Share on other sites More sharing options...
moonfresh Posted May 26, 2021 Share Posted May 26, 2021 Hey, is there enough clearance to remove the crank pulley with an impact gun? Going to attempt this myself in a few weeks. Any other tips? Thanks. Quote Link to comment Share on other sites More sharing options...
Maineah Posted May 26, 2021 Share Posted May 26, 2021 I don't think you can with out removing the radiator but doing so gives you a lot of room to makes the job a little easier. Quote Link to comment Share on other sites More sharing options...
jjrbus Posted May 27, 2021 Share Posted May 27, 2021 Pull the radiator and have some room to work. While the radiator is out flush the block and flush and flush. I was amazed at the amount of crud that came out. Quote Link to comment Share on other sites More sharing options...
moonfresh Posted May 27, 2021 Share Posted May 27, 2021 Thanks guys. I will definitely pull the radiator. Any other tips/tricks? I'll keep you guys posted with pics. Quote Link to comment Share on other sites More sharing options...
