DDK - Die Deutschen Klassiker

I've been doing some more thinking about replacing the crank seal behind the pulley. Up until now I've presumed it's an engine out job but over on Pelican there's an alternative suggestion.

Support the engine, remove number plate panel, exhaust box, engine mount, et voila, full uninterrupted access to the inner sanctum. (the pulley)

So then, how does that approach sound to you guys who own your own spanner ?

Mike,

Perfectly reasonable
You need to do most of that to START to get the engine out, so press-on!
Good luck.
Been spannering the brakes onmy old girl so good to know someone else is having a go instead of watching Le Mans on TV.

Thanks Graham, that`s all the encouragement I needed.


The pulley seal on my car has been leaking for a long time now, resulting in a clarty fan and a regular gas attack spewing out of the passenger windscreen vent. Sinky horrible stuff.


So new seals were ordered up, along with a pair of silencer gaskets and the Apprentice and I removed the back end of the car in short order. PET shows two seals, one undersize, so I ordered both just in case but the standard size worked fine. Never did get to the bottom of when an undersized seal would be required... unless of course your crank had worn down by half a mil.

The overriders and number plate panel were unscrewed and the exhaust removed. Then with the engine supported on the jack the engine mount was removed (an easy job, the rubber engine mounts were replaced last year) along with the rear most piece of tinware that's in the way.

Et voila.



The pulley bolt unscrews with an impact gun , pop the old seal out... pop the new seal in, Bolt everything back together and..

Job`s a goodun.

Then, of course, just to check everythings working perfectly, the Apprentice has always to to testdrive my poor, delicate, beautiful little short wheel base 911. We strap ourselves in (me, a little more securely than is normal) and James spends the next half an hour treating us to ( ) a bit of a meander down a few country lanes. The sort of meandering that the Nurburgring has become famous for.

Still, once again, we lived to tell the tail and the pulley seal and fan are as dry as a bone, all mended with the minimum of fuss.

Thanks Mate, maybe next time you can have the engine out.

Mike.

Very impressive stuff Mike - well done

HI Mike
please tell me that you DID disconnect the gear-linkage before dropping the engine down to that angle!!!!!! if not it looks like you may have a oil leak at the other end?

regards mike

Hi Mike, thanks for the reminder.

I should have added, if you do drop the engine down this far, it`s important to disconnnect the gear linkage to avoid future oily disappointments.

Regards, Mike.
