Rav4 3S-FE Cam Timing and Crank Tensions

Hi all,
I've been rebuilding a 3S-FE that I did not pull apart.
I am giving it a complete rebuild but I can't seem to find any info on crank and bigend tensions.
Also the head was given a complete rebuild and I now have it back from the shop and need to find some info on where the cams actually line up, I already have found a pic on the setup of the timing belt.
Any info will be much appreciated, regards Pete.
P.S. Have experience doing this sort of thing, only didn't pull this one down and other twin cams have had two cam gears for the belt, these are quite different with there setup of only one.

Are you asking about the camshafts alignment to each other (intake to exhaust cam)?

Can you clarify big end tension I am not familiar with that term. (taking a guess you mean harmonic balancer/dampener bolt torque?)

Yes the way the cams line up together, just to double check I have it correct.
The bigends are the conrods to crank connection bearings/joint.

The intake cam knock pin (dowel pin that locates the t-belt pulley) should be at 10-45' deg BTDC (top dead center of the knock pin would be at 12 o clock just for reference use 10-45'deg BTDC) then use timing marks shown in pic

oil treads and under the nuts of the connection rod cap
Connecting rod torque is 25 N.m (18ft.lbf) + 90'deg turn

Thanks for the reply. I went to Toyota today and they gave me some photocopies of those pages from their manual so they are all I needed, they were very helpful.

Wow -- rebuilding an engine without already having (and reading in advance) the service manual. Not recommended! But good luck with the project.

Somewhere is one of my threads, from a couple of years ago, about pulling the head to do the valve stem seals -- you might find it interesting.
