flywheel woes
 

The WR engine rebuild has been challenging (to say the least)... And the prep work for CO setting and MOT saw the worst nightmare come true... It's dropped its recently fitted flywheel timing pin.

So, the question is one of balance really... The engine and flywheel were calibrated together, clearly removing the flywheel, drilling it, and refitting a new pin will, by default, upset the balance. (Thus negating the benefits/costs of all the balancing work, I assume)...

Just how critical is the flywheel balance?, we've got two options now, refit a pin to the broken 'balanced' flywheel and hope it holds or fit a spare WR flywheel?

Thoughts please?

Kind regards

I machined a new pin for the 200 turbo flywheel due to one of them being missing, difference between it and the sheared off one would be absolutely miniscule as it was sized to the remaining item.
Made it an intereference fit based on the remnants of the removed one and pressed it in with some loctite just to be 100% sure of it.
Solid as it should be.

HI,

I was running my 220TQ with the lack of two flywheel pins (the diagnostic ones on the opposite site of the ignition point pin) for several thousand miles and I recognized no problems like vibrations or noise.

As a new gear rim can be shrinked on the flywheel at any time as it is an extra sparepart, I wonder if balance is a big issue. Why was the pin dropped, btw.?

Surely the company that fitted the pin are responsible for this Simmo and also for correcting the problem? As Tony says as long as the pin is of the same dimensions it won't affect the balance

SNORT!!!

24p from Audi - must be one of the cheapest parts.

I thought itd be NLA...lol :D

Well, that was another interesting, if potentially expensive day.

On the endoscope we'd assumed the pin had snapped off in the flywheel as it looked like this on the screen.

But

When we took the subframe off and exposed the flywheel through the bottom plate, we found this...

The hole completely empty and the pin laying at the bottom. The pin is 3.95mm in a 4mm hole. Glued. This, in some respects was a relief as it made fitting a new one a lot easier.

Anyway, the expensive bit. The Crank Sensor's taken the hit as the pin slipped out, ETKA shows £156+VAT. Nice.:eek:

:yikes:

Hi,

If it is identical with the Sensor of the 220V or the V8, we can check this New for 100EU.

And: My Sensor was Hit as well by the flywheel pin - even though it was disfigured, it worked well another couple of years. HaVe you checked e functionality?

Merry Christmas,
