Just a random question. I am replacing my timing belt on my 92 4runner, (3.0) and using the manual as I go along. The manual says to use specific timing marks on the belt. Neither my brand new one (goodyear gatorback) or my old had any kind of marks on them. is there a number of "teeth" that should be between the marks on the cams? or can I install and just make sure I have no slack and all the timing mars align? Thanks

 

If I remember correctly I believe some people have had time issue by using another timing belt other the an oem from toyota. My advice would be to get one from toyota with the timing marks on it. In my opinoin this is only a job you would not want to do in for a long while. So instead of guessing and possibly having problems down the line just get a belt from toyota to save time and trouble. Thats just me though

 

Thanks, I think I am going to go that route and just eliminate any room for problems.

 

just make sure the marks line up on the cam sprockets and on the crank and you should be fine

 

OEM is always best, but any belt will work. Just make sure the mark on the harmonic balancer points to 0, and the cam gears buth line up at the match marks. Super easy to do.

 

thanks, I was just worried that there had to be a specific amount of teeth in between those marks. I just got done working on my motorcycle that is that way so I had it in my head.

One other question though: If I line the cam pulley up to the mark how do I know that the cam is on the correct cycle? In the same way that you can hit the tdc mark on the crank pulley but be 180* off. Is that possible on the cams as well? Thanks again for your and everyone else's help.

 

If a cam is on its mark, its on the correct cycle. Same thing with the crank. Remember, if you go 360 degrees around, you have gone one full cycle. The 180 degrees off thing only applies when the timing belt is hooked up and the engine is turning over, since the cams turn 1/2 the speed of the crank.

All long as both cams and the crank are on their marks when you put the timing belt on, you are good.

 

Thanks again Cougar, I think I got it all squared away. I just have to go get a torque wrench that can go up to 181 ft.lbs so I finish up the crank pulley.
