Alright, so my one friend is going to come help me but i havent herd from him yet. And i really want to finish my timing chain. So heres a quick question.
im setting TDC so i can remove the cover and everything. My question is am i fine to remove the cam sprocket, its not perfectly lined up.. il show you a couple pics for reference.




Pully says 0


Distributor is set a 11oclock


Stupid owner put the sprocket on backwards, but the dot is lined up



Only thing im worried about, is the distributor gear drive okay thats its not perfectly vertical?

Thanks guys!

Are you taking it apart to replace the timing chain?

Rocketwrencher

By the way, Once installed, The crank puly should be set to 5deg. on the compression stroke, not zero.

algranger

it should be set to 0 hence the term TDC not 5% TDC
once its at TDC you can pull the upper gear off just dont let the chain hang down and come off the teeth of the lower sprocket unless you plan on removing the timing cover.

This is wrong.

the crank and cam should both be at the matchmarks.

You set Distributor timing to 5deg BTDC with the check connector short circuited at idle. Distributor (aka ignition) timing is NOT the same as cam timing.

Rocketwrencher

Clarification: When installing the distributor, the crank should be at 5 deg. Unless Chiltons is completly wrong.

Also wrong. The crank should be at ZERO. 0 TDC on the compression stroke, and the dizzy rotor will point to #1.

The ignition timing (distributor) is used to adjust the timing to 5 deg BTDC with the check connector short circuited. If chiltons tells you to install the dizzy with the crank at anything but 0, it is wrong.

Rocketwrencher

It def. says 5 deg. for the 22re only. All other engines at zero. unless I am completly reading it wrong but I doubt it. Check it out section 2-5 of Chiltons 1989-96 repair manual for p.u., 4-runner, and land cruiser.

ok, well, its incorrect. Or you are reading it wrong. Double check they are not talking about ignition timing.

It has to be at Zero.

first things first: turn the camshaft sprocket around the right way! the 'dot' on the camshaft is offset from the 'dowel' in the cam in order to compensate for the slack in the timing chain being taken up by the chain tensioner. The way it is installed is going to retard your cam timing too much to let the distributor be adjusted properly, not to mention that the cam that far off WILL CAUSE PROBLEMS.
If you can't, or don't want to, get in and check the crank sprocket, mark which link on the cam chain the 'dot' lines up with, then pull the sprocket and flip it around, making sure that the chain DOES NOT COME OFF the crank sprocket. Then install it with the 'dot' matching up to the SAME LINK as before. You WILL HAVE TO rotate the camshaft (or crank and chain if you prefer) to do it.

I am putting everything back together after a head gasket job. The FSM doesn't include re-installing the distributor in the "Head" section, so you can only find instructions on installing the distributor in the Ignition section. This link shows that section:

http://beefstorm.com/files/5distribu.pdf

It shows you setting it to 5 degrees. This is from the 1993 FSM. Is there another section I should use for re-installing the distributor, or is it the correct way?

Hmm, this is certainly news to me. Everything i have ever read says 0, including my FSM for my 87.

Maybe it changed for 93?

Either way, 0 or 5, it will be correct or close to correct. Each tooth on the dizzy gets you about 20 degrees or so, so you would have to be WAY off.

Thats really strange, as I did one in a '90 and '94 with it set at zero and had no problems.

there's enough 'slop' in the distributor adjuster to allow for +/-5 degrees of crank position (about +/-2.5 degrees of cam position).

I still think you need to turn that cam gear around though.

yeah we did, when we put the new one in we installed it correctly
