Ok, so I read through Vince's walk through on how to time a 1.6TD engine. Although it's very helpful, it didn't solve my problem. I have a 1.6TD that I'm installing into a 1996 Suzuki Sidekick. I'm not 100% I have it timed correctly and I'm about to change the timing belt. I have a complete engine with the flywheel, but no tranny. I can get the cam and injection pump timed (I have the dial gauge and other items needed). I just don't have reference point for the engine. I was told by the seller I could align the flywheel mark with the center of the engine to get it to TDC. Before I go blowing up an perfectly good engine I thought I would ask if anyone knows for sure.

not sure of a quik/ easy way to time with out a trans, you should post your location maybe some one would stop by with a trans and slip it on, than you could time it and make a reference pointer on the ft engine dampner for future reference.

you could take out #1 injector or glow plug and put something soft in it to measure TDC. A straw from a WD 40 can or similar. I wouldn't time the IP that way, but you could get it close enough to get the cam, crank, and IP to where they wouldn't destroy eachother. Make sure to push toward the meat of the head to get an injector out or you could break it. Don't pull your wrench away from the head...if you don't understand don't wrench until you do.
-
I have done the straw trick, mostly to ensure the flywheel mark was ok.
IIRC, you can also push down the intake valve on #1 and hold it with a shim (or screwdriver), then carefully turn the crank one direction until the piston gently touches, mark that point, then do the same the other way... halfway between the points should be TDC.

So it has the Volkswagen flywheel still on it with the timing mark in it?? If so, you're in business.

This guy does not have his aligned properly.. ;) but that little diamond cutout is your TDC mark. Put that mark in between the two top transmission bolt holes. That will be exact TDC for the crank. Because if you look, the timing hole is dead center of those two bolt holes.
-
I have a garbage tranny and a sawsall. I could send you the top piece of the tranny. IM me if you're interested.
8v, have you measured to confirm that it's dead nuts between the 2 bolts?
-
I have timed them this way about a half dozen times (aka no tranny). And all have run, bang on. I do not know for a measurement fact, but I am 99% sure.

Jeremy, you are wrong..
the diamond notch is 6*BTDC
look just to the right of it. see the little dimple that looks like a casting flaw?
thats the TDC mark..
the TDC mark is always at the edge of that bolt hole.. ALWAYS.
-
Yup, you are right. The diamond is NOT TDC.
-
We are talking a 1.6 vw diesel flywheel?
My bently shows a diamond mark for tdc and I have always used it. I just went out and looked at all my flywheels and they aren't even like the one pictured? Not near a bolt hole and all mine have diamonds with nothing else around. Some have the circle under the diamond.

I concur... ;)

for real? the diamond isnt tdc? That circle is? I have always used the diamond as tdc.

^^ for real? the diamond isnt tdc? That circle is? I have always used the diamond as tdc.
What??? Heresy. I have always taken as gospel that the diamond is TDC. I am sure the Bentley I have proclaims it (talking about the correct diesel flywheel here). We need to form a committee to study this...
-
If I understand correctly, in order for the engine to fire correctly, the bottom half is off a few degrees in order to have a complete combustion. Someone correct me if I am wrong.
-
dude, the diamond is a TIMING MARK..
the DIMPLE NEAR THE BOLT HOLE is the TDC mark..
someone pull an injector and stick wire down the hole..
if you time your engine to the diamond, it will KNOCK when you shift.. ask me how i know..
-
I'm so confused now ???

85 Jetta GL Turbodiesel flywheel.
Yes. Please clarify. I had mine aligned as per the Bentley manual for about 100,000 miles.
-
Yes, Kevin please try and stop the non-informative posts when there is already confusion lol! It makes it more confusing.
I was pretty damn sure the DIESEL flywheels had the diamond timing mark.
Here was my 91 NA. A diamond right by the hole.

Now here is my 210mm gas flywheel, as you can see the dimple is over and to the left of that hole. So I referenced a diesel flywheel and copied marks and notched my own for my TDI application.

I just checked the flywheel on a 1.8 gasser my brother and I pulled out of his cabriolet--it's the exact same as in the one in the picture. This leads me to conclude that:
ROR is correct when he says the diamond on the flywheel in the picture that 8v posted is indeed NOT TDC, but instead a timing mark, meaning that to use that particular GASSER flywheel, you would indeed need to time to the circle, not the diamond, as ROR suggested. However, on all DIESEL flywheels, USE THE DIAMOND AS PER BENTLEY or prepared to be very sad.
-
Time to the Diamond unless you know for sure you are running a Gasser flywheel.
Also, for what that picture was originally intended. Yes dead center of those two bolt holes is TDC. The pointer in the trans housing is right in the center of those two bolt holes.
-
when the DIAMOND AND DIMPLE are right in line with each other, they are TDC marks..
when the DIMPLE is 7/16" from the DIAMOND, then its NOT the TDC mark..
see the bentley post, thats a dimple and diamond in line with each other..
those are both in the same relative position, and both TDC marks..
-
My dimple has diamonds, or is it that my diamond has a dimple? Either way, diesel motor and flywheel so both in line as in the picture. Keep it stock and you don't have this kind of confusion. But no fun either.
