Toyota Timing Belt

[joeydirt]

Am I allowed to talk about yotas here? heh

I think Im good to go here but wanted to get some thoughts before I actually fire it up since its an interference motor. So I changed the timing belt on my 4.7 tundra using the 50 degrees ATDC mark at the crank and the T marks on the cams and after a few manual rotations they got out of sync. I thought I did everything right but apparently not either the belt slipped or I need glasses. So I tried again but this time using the TDC mark on the crank and cam, and everything stays in sync. I have the plugs out for ease of rotation and there does not seem to be any resistance or noises. Allthough Im not sure there would be if there was a timing issue and the valves and pistons were crashing. So thoughts? Some of my readings indicate its is a bad idea to rotate the cams without the belt hooked up but Im assuming this is to avoid spinning the cam when a piston in that bank is at TDC so you dont bend a valve.

Welcome to the site.
I used to own one of those 4.7's in a four runner a while back. Great engines. I am getting ready to do a timing belt swap on my 3.3 in my Highlander and have found a wealth of "how to" information on Youtube. Look up your engine in their search feature and I am positive you will get all the information you need in video form.

Let us know how it turns out.

My neighbor has a 4.7 in a toyota and i looked up the recommended service intervals and it mentioned valve clearance as a needed item. I believe it's a 2004. Further searching on alldata pro found that the style of valve clearance adjustment is a select fit disc. You measure the clearance, record it, and then look on a chart and order the new correct thickness disc id adjustment is needed. If memory is correct my recommendation by 100,000 miles was a t-belt, tensioner, waterpump (might just as well) and the valve clearance adjustment as per the service sheet. Good luck.

jobs complete, I was just being paranoid I guess. Thanks for all the help
