The CPS is easy. Here's how I do it broken down into tiny steps:
Remove cap so rotor is visible.
Line up circle indicator with notch on the other end.
(I don't do this, but you might as well) Use a magic marker to place a mark on the rotor and on the CPS/Dizzy housing so you can relocate/verify 0? easily if you need to.
Now, insert the shaft in the hole...
Giggle like a girl. (optional)
Before seating the CPS/Dizzy, rotate the whole assembly so the CPS/Dizzy retainer bolt's hole is in the CENTER of the eccentric opening.
Now, as long as the rotor is still at 0?, insert!

NOTE: Due to the cam and rotor's helical gears the rotor will rotate a little bit as it turns. If it doesn't line up very close to 0? when inserted try backing it out and rotating the rotor just a hair clockwise or counterclockwise to correct for the rotation. Mine's not dead on, but it's only off by 1/16" or so... With the dizzy lined up to the center of the eccentric bolt hole my timing is pretty much at 0?. You don't have to do it this way, but it makes things easier sometimes and you can then confidently mark the CPS/Dizzy housing to reflect where 10? is.

bolts moved smoothly all the way. used the goooooooooy stuff they gave me. did it in 3 passes also to make sure everything was tight.

rev rev rev rev..... POP

Okay... I'm just the paranoid sort; It's served me well over the years.

Well, don't blame ya if you do, but I'd go over it all one more time... you're missing something. If it's back firing through the intake either the mechanical timing is off or the plug wires are installed in the wrong order.... same thing's likely if it's doing it out the back too actually.

I'd go back through the TRSM's reinstallation segment and double check everything. http://www.cygnusx1.net/Supra/Librar....aspx?S=EM&P=1

Make sure you do not over tighten the timing belt tensioner pulley, it will distort the #1 cylinder rather easily if tightened past specs.

i dunno cre. im kinda scared to see whats dead now. there was smoke in the engine and no power after last night. grrrrrrrrrrrrr

[cvbikeguy]

ok so my friend says that the smoke is nothing. grrr

"keep trying"



ok so. lets think this through again. the cam gears should be pointing up as the crank is at 0. right?

i take the cap off the dist.... sh*t as i was reading i was going over cre's other post.

"Line up circle indicator with notch on the other end."

circle indicator? that little hole inside the dist?

i lined up that little notch with the other little notch on the side...

God im hopeless

does it matter how the cap is installed?

[cvbikeguy]

ok so i start work tomorrow. i know its sad that i still cat understand this process but any help is appreciated. what is the notch and indicator? people keep saying to point the arrow to cylinder 1. and does it matter what way i have the dist. cap?

[oregonjoe]

The cap only goes on one way - its keyed.

Besure you got the plug wires correct on the cap and locate the #1 Spark terminal on the cap. Then mark the distrib housing where the post is.

When the distrib is installed correctly, the rotor will boin to the mark when the engine is at TDC on the crank mark.

But the engine is TDC twice during cycle so be sure ist on the compression stroke. Put a screw drive in the #1 spark hole and be sure it tops out at tdc or else its on the exhaust stroke.

Any errors in putting timong belt on will also cause the symptons. Need to look at cams and be sure valves are opening and closing at the right time.

Be sur ethe two marks on the cam sprockets ling up on crank TDC. You need to check that after several rev as the belt will tension and stretch after install
