HELP!! 4AGZE TIMING BELT - no back plate :(

[AE101LEV]

ok now im up s##t creek and need helps!

I have my cams out and the gears off with teh belt still attatched to them with wireties so it didnt move any teeth.

I couldnt get the belt back on so I have tried to take crank pulley off to lossen the tensioner and the crank has moved

I dont have the plate that goes behind the gears so align the notches in the gears up with - some fucker threw it out GRRR

umm on 4ag's you line a dimple on the lower timing sproket up with a simple on the oil pump housing

edit: oh i see your issue not lining up the crank but lining up the cams.

didnt you set the engine at TDC before you pulled it apart.. hence shouldnt the cams and belt be at TDC so lining up tyhe crank at tdc and then placing the cams back in place ?

[AE101LEV]

no i didnt set it TDC, i didnt know i had to until i couldnt get it back together valves were open. it all came apart so easy but it just wont go back together

do you have the plastic cover for the cam gears as well? cos il take that too

Don't despair, you should be able to get it close enough to run without the plate. Assuming you still have the pulleys tied to the timing belt:

1 - Set the motor to TDC.

2 - Pull off the oil filler cap and turn the inlet cam until you can see a little 'notch' which should align with the shelf under the cap:



3 - The cams should look like this from the front:



Notice I've marked the pins in red.

4 - That should be OK, but I'd suggest you pop the rocker covers off and have a look at the cams themselves. At TDC, they should be basically a mirror image of each other with the lobe for no1 on the outside, just up from the horizontal:

Inlet:


Exhaust:


That should be enough to get you out of trouble.

i always rebuild my ge/gze's with-out the silly backing plate. i like the open cam wheel look.

There's 13 belt ribs between the two marks on the cam gears, if that helps.

So - What do you do with the wiring loom which goes behind them?

[AE101LEV]

prob same thing I did

put some pretty plastic over the wires and re-tape, shift the loom over and wire tie it to the TMIC bracket at the front of the motor and the hook at the rear of the motor.
