That is it. I want the big flywheel for my engine. I would like one that is usable. I don't really want the gasser one, more the 1.9 diesel one since I won't have to mess with the timing marks. Let me know what you want out of it. Lucas ><>

There's a difference between gas and diesel 210mm flywheels? Why would they be different? Shouldn't TDC be the same between gassers and diesels?

I think the gasser flywheels use marks at 8 degrees BTDC or something funny and confusing like that. I've only owned 2 gas VWs so I could be way off on that one though...

You got it... the gassers have no TDC mark... it's of no use to them. :wink:

Having said that, if you remember that pi=3.14 and the circumference of a circle = pi * d you can scribe your own.

so if gassers don't have a mark on the flywheel for TDC, how do make sure the timing belt is installed correctly when you replace it?

Using the 6 degree BTDC mark that *is* there and scribing a TDC mark of your own using the formula for the circumference of a circle.

Or, using piston height.

Or, using the instructions found in (some) of the Bentley(s) for a specific distance from one of the timing lugs.

that's not what I mean. say you have a factory gas Mk2 car. you're doing a timing belt with the motor in the vehicle, as in preventive maintenance. How do you make sure you're at TDC when you install the belt if there's no TDC mark on the flywheel?

TDC is irrelevant. You use the BTDC mark on the flywheel, the notch in the cam gear and then align the distributor so the rotor is facing the proper way.

You are basically timing the motor BTDC, instead of at TDC

are you talking about valve timing or ignition timing?

Both. Again though, I'm a diesel guy, not a gas guy so I could very well be wrong. I did 1 t-belt on my friends 8v digi engine but that was a couple years ago now

funny I thought you needed a timing light to do gasser ignition timing properly.

sorry tyler if I sounded kinda snarky there...I just don't think there's any difference between gas and diesel 210mm flywheels that's all. The 0 mark on the flywheel is TDC on gas and diesel vehicles with a 210 mm flywheel. Look up the part numbers on vagcat.com gassers and diesels take the same part.

You're both right... some gasser flywheels have a small TDC dot... others don't, and of course over time VW has worked to consolidate their inventory.

The real message is, whichever flywheel you have, take a couple minutes to check that you know where TDC is as you install it.... we see lots of conversations with people that troubleshoot engine problems for a long time, only to discover in the end that the root problem is that TDC isn't TDC on their particular flywheel.
